BACKG~OUND O~ THE INVENTION
1. ~ield of the Invention
~ 'he present i~vention relates to communication
termirl~ls which are connected to a communication network
throu~h ~ da~a channel for transfer of such data as line
transaction data or packet transaction data and throuqh a
slgna] channel for control of a ~all to a communi~ation
destirlation p~rty, and ~ore particularly, to a
commurliçAtion termin~l apparatus which can realize
effective communication processing o~ the basis of proper
identifcation of subscriber numbers or subaddresses
received or transmitted thro~gh the si~nal channel as
i~lentification da~
2. Description of the Related Art
~ n prior art communication networ~s, a data ch~nnel
for ~ransfer of transaction data is separ~ted from ~
sign~l channel for tr~ns~er of control data as mentioned
above so th~t, for example, the contr~l data can always be
trsnsnlitted through the signal channel independently of
voice or pic~ure dat~ as the transa~tion data or con~rol
of a plurality o~ such data ~hann~ls can be established
throuc~h the single signal ch~nne~, whereby different sorts
of se~vices including t~lephone, telex and facsimile can
be efficientLy and integrally realized. One of these
pr-ior art comm~nication networks is, as well know~,an IS~N
(Integr~ed Services ~i~ital ~etwo~k)~
1 334866
In the ISDN, the above data channel is referred to a5
the B channel and the a~ove signal ~hannel is referred ~o
a~ the D channel. Thro~gh ~he D channel o the signal
ohannel, i~ particular, identific~tion d~ta on caller
communica~on terminals ca~ also be transmitted as con~rol
data. Accordingly, a ~ommunication termi~al to be called
can know, on the basis of the identific~tion da~a of ~he
caller- communication terminal received th~ough the D
ch~n~el, one of the communic~tion terminals which issu~d
the transmissio~ data ~voice or picture da~) of th~ B
chann~l. The identifi~ation d~ta includes subscriber
numbers previously designated to subscribers of the
communication netwo~k and subaddresses arbitrarily set
among some of the subscribers as additional data to the
subscriber numbers. The subaddres~es, which are attached
to some of the subscriber num~ers as necessary, are used,
for exa~ple, when it is desired to specify one of a group
of ~erminals (user in-home facili~ies) to which a common
subscriber number is designated.
Such IS~N ~an ind~ed re~lize such various sorts of
services as mentioned abo~e integrally and efficiently and
also can allow the signal-r~ceived (receiver)
communication termin~ls to recognize the caller
communication te~minal on the basis of the identification
data of an incomin~ signal received from the D ch~nnel.
In the prior art communi~a~ion terminal appara~us
~onnected to the ISDN, however, the identifi~ation data
has been used onl~ for the purpose of thç reco~nization or

ident~fi~tion of the caller termi~al and processing,
control and so on concerninc3 the actual communic~tion have
been separ~tely carried out through operator's cont~ol
panel. As a result, the ISDN has not fully been utili.~ed
in overall communication ~ficiency.
~ `or example, the following utilization forms (a) to

impro~ed user interface as a co~m~nic~tion ~erminal
apparcltus and thus realizing a hi~h communication
eficien~ of the overall commu~i~ation ne~work. However,
it has ~een impossible for the existin~ communication
t~rmir~al appara~us, even how it is connected to the ISDN,
to re~ e these utilie~tion forms.

carried ou~ so that, when the sensor detects the
communi~ation disable st~e~ th~ re~eived identification
data ~f the second memory is transferred to the seventh
memor~ a~d stored therein, while, when the d~tec~ion of
the comm~nica~ion disable state by the -~en~or is r~leased,
the r~!ceived identification data of the seventh memory is
auto~atically called and the message da~a of th~ eighth
memory is automatically transferred to the communic~tion
terminal apparatus corresponding ~o ~he called
ide~tification data.
~ s a result, the call~r communic~t1on termina~
apparatus c~n smoothly be operated and the waste time due
to the communication disable state can be elimina~ed.

a~tom~,tic transfer mechanis~ of the apparatus of the first
embodiment will be detailed by referring to Fig. 2.
- .
1 334866
.
~ ssume now that a~other communication terminal (not
shown facsimile ma~hine) connected to the ISDN issued a
signa~ to the first embodiment appar~tus shown in Fig. 1.
Then t.he caller communica~ion terminal first sends to the
ISDN cl signal for calling the irst embodim~nt apparatus
~which signal is referred to as the calling signal). The
calling signal usually contains a dat~ indic~ive of a
caller subsc~ib~r number previously desi~nated to t~e
signal-originator (caller) communication terminal.
q'he callin~ signa~ thus sent to ~he ISDN from the
caller communica~ion termin~l is received as an in~ominq
call signal at the network controller 11 of tho embodiment
~pparatus through the ~SDN line (D channel).
l~he first embodiment apparatus, when receiving the
incoming call signal at the network controller 11 and
recogr,izing the presence of ~he incoming signal at ~he
centrzl controller 1 (s~ep 101 in Fi~. 2), starts its
proces.sing in the following manner.
~1) The central controller 1, when recognizing the
preser,ce of the incoming signal on the basis of
no~ification from the net~ork con~roller 11, ~heck~
through the network con~roller 11 whether or not the
incomi~g signal contain.c the c~ller subscriber nu~ber of
the calller communication terminal (step 102 in Fig. ~).
(2) ~hen h~ving determin~d th2t the caller subscriber
number is not in~luded in ~he incomin~ signal, the central
contrclller 1 controls the e~bodiment appara~us to perfo~m
its u~;ual incoming-call answering ope~ation. That is, in
-l5-
- 1 334866
this case, a picture d~ta sent together with the incoming
signal is suitably~dem~du~ated through the communication
controller 12, transmitted to the picture buffer processor
37 an~ then recorded on a recordin~ paper through the
recorder 35 (step tO3 in Fig. 2).
(3) ~Yhen determining (in step 10~ in Fig. 2) that the
caller subscriber number is included in ~he incoming
si~nal, the central controller 1 causes th~ reqister
contrc,lle~ 4~ to set (store~ the included caller
s~bsc~iber num~er in the ID regi~ter 42 (step 1~4 in Fiq.
2). At this time, if another c~lle~ subscrlber number
(corresponding to the previous incoming signal) is alre~dy
se~ in the ID regi~ter 42, then the previous caller
subscribe~ n~mber is repl~ced by the n~w one for its
r~newal, unless the I~ register 42 is cleared each time
the pro~essing is completed.
~ 4) The central controller 1 ne~t checks whether or not
the c~ller subscriber number for specifying the caller is
previc~usly regictered in the caller ~D memory 44 (step 105
in Fi~l. 2).
(5) ~rhe controller 1, when determinins that ~he caller
subsc~iber number is not registered, ~ontrol ~he
embodi.ment apparatus to perform i~ ~su~l incomlng-call
answering operation as in (~). the above p~c~essing
Thereby, a picture dat~ being sent as associ~ted with the
incomi.n~ call si~nal is suitably demodulated through the
commw~ication controller 12, transmltted to the picture
buf~e~ processor 37 and then rec~rded on ~ recording paper
-l6-
- 1 3 3 4 8 6 6
through the recorder 35, as has been explained abo~e.
(~) rhe eontroller 1, when deter~ing tha~ the caller
subscriber number included in the incoming signal is
reqis~ered in the caller I~ ~emory 44 (step 105 in Fig.
2), reads out associated ~ne o~ ~he caller s~bscriber
nu~bers f~om the caller ID memory 44 through the memory
controller 46 and compares the read subscriber number with
the s~ ccriber number set in the ID regis~er 42 (step 106
in Fig. 2).
(7) When determining to be a none-coincidence in
subsc~iber number as the comparison result ~step 107 in
Fig. 2), the cent~al controller 1 repeats the above
processin~ (6)(step 106 in Fi~. 2) so long ~s other caller
subscriber numbers are registered in the caller I~ memory
44 (st:ep 108 in Fig. 2). When the central controlle~ 1
dete~mines that any one of the subscri~er numbers
registered in the caller ~D memory 44 does not coincide
with the subscriber number set in the I~ re~ister 4~, ~he
controller 1 controls the embodiment apparatus to perform
i~s usual in~oming-call ans~ering operation as in the
above processing (2) (step 103 in Fig~ 2).
(a) When de~ermlning through the compa~ison (step 106 in
Fig. 2) to be a su~s~ribe~ num~er coinciden~e ~tep 107 in
Fig. "), the central controller 1 answers to the incoming
call ~ind then controls tc s~ore in the pict~re memory 2
the plcture data re~eived through the network controller
11 and the communic~tion controller 12 (step 109 in Fig.
2) .
1 334866
~ g) When the input picture data h~s been stored in the
pi~tuAre memory 2 in-this wa~, or in othe~ words, when the
above coincided subscriA~e~ number hac alread~ been
registered in the caller I~ memory 44, the central
controller 1 next re~ds out from the receiver ID memory 45
one of recei~er subscriber numbers registered in the
receiver ID memory 45 which is assoc~ated with the
~oincided caller subscriber number through the memory
controller 46, and performs the c~lling operation of the
read receiver s~bscriber number (desired s~bscriber number
to be transf~rred) throu~h the communicatio~ controller 1
and the ne~work controller 11 (step 11~ in Fig. 2).
(1~) When the callinq op~ration causes the present
apparatus to be put in a data ~ransaction en~Able st~te
wi~h the party communi~a~ion terminal (the faccimile
machine to be called), the cent~al controller 1 fin311y
transfers the pickure data stored in the picture memory 2
to the party co~mu~ication t~rminal newly put in the
communication state (step 111 in Fig. 2). Of course, such
data transfer is ca~ried out also und~r the communication
contraller 1~ and the network con~roller tl making up the
communication part 10.
Through the above processings of the apparatus of the
first embodimen~, the prese~t embodimen~ app~ratu~ c~n
also ~e used as a relay terminal to realiAze picture data
automatic transfeAr between the specific communic~tion
terminalsA In other ~ords, even if the operator of the
present app~ratus is absent, favorable pictu~e data
-18-

Eurther, although onl~ subs~riber num~ers ha~e ~een
used as identific~tion data IDs respectively uniquel~
specifying commu~ication ~erminals in the above
embodiment. since a subaddress ~ogether wi~h a c~lle~
subscriber number is also sometimes included in an
incoming signal in s~h a comm~nication network, this
subaddress may a1so be positively utilized as an
ide~tificatio~ data ~D specifyin~ one of the communication
termirlals. In this cas~, this subaddress of the incoming
signal is also temporarily sto~ed to~ether with the
su~s~riber number of the incoming ~ignal in the I~
re!gister 42 and also arbitrary subaddresses a~e previously
regist.ered toge~her with the associated subscriber numbers
specifyinq caller co~munica~ion terminals in the caller ID
memor~ 44. And when the present embodiment apparatus
recei~es an incoming si~nal, ~he apparatus executes the
~bo~e dat~ automatic trans~er pr~cessi~ only un~er the
condit.ion that the subscribe~ number and subaddress of the
incoming siqnal both coincide with associated ones of the
registered subscriber numbers a~d subaddresses
r~specti~ely. The ide~tification data IDs to ~e
regist.ered in ~he recei~er I~ memory 45 may comprise only
su~tsc~-iber num~ers or may ~omprise subsc~iber numbers
added with associated subad~resses. ht least when such
subadclresses are added to the associated s~bscriber
numbers as in the lat~er, desired ones of the
commurtication te~minals to which the data is to be
transferred can be more finely spe~ified~
- 20-
1 334866
~ n either c~se (in both cases o~ su~sc~iber numbers
with .ind without a~sociated subaddresses), ~he number of
caller- identification data IDs (caller su~scriber number~)
tcl be reqistered in the ~aller 1~ memory 44 may be se~ ~o
have a one-plurality or plurality~one relationship with
the number of receiver identification data IDs (receiver
subscriber num~ers) to be registered in the receiver ID
memory 45 as associated with ~he calle~ ones.
In the case where these identifi~tion dat~ IDs are
r~!gist.ered in ~he aboYe one-plurality rela~ionship (one
caller and a pl~rality of receivers), a pictu~e data from
the single c~lle~ communication terminal is transerred to
the plurality of desired communication termin~ls at the
same t;ime or on a time s~ries ~asis.
In the case where these identification data IDs are
regist.ered in the above plurality~one rela~ionship (a
pl.ura~.ity of callers and one receiver), pic~re d~ta
s~par~ltely sent from the plurali~y of c~ r communication
~ermirlal are separately t~ansferred to the single desired
receiver communic~tion terminal.
E.~planation has been made i~ the foregoing first
embodiment on the assumption that these caller and
r~cei~er ID memories ~4 and 45 a~e both memories
incor~orated in the facsimile machine o~ the first
embodi.ment, but one or both of the caller and receiver I~
m~mori.es 44 and 45 may comprise an external memory freely
attachable to the body of the facsimile machine as sown by
a broken line in Fig. 1~ When such an external memory is
- 21-
- 1 334866
emp~oyed, the data of the c~llers and receivers concerning
data t.ransfer can be freely carried. In addition, if the
exteralnal memory is such a simple IC-card writing device,
then t;he writing operation can be easily achieved ~t any
place. From the viewpoint o~ reallzing the more f.Lexi~le
applications of the presen~ apparat~s as a communication
terminal, it is highly important to positively m~ke these
memories 44 and ~5 in the form of such ~n external memor~.
E'~g. 3 s,hows a second embodiment of the ~ommunication

1 334866
appa~tus of Fig. 1 a~d thus the following explanation
will be concentra~ed on the arrangeme~ an~ ~unction of
the s~!cond expansion part 50.
~ s shown in Fig~ 3, the se~ond expansion part 50
includes an auxiliary-da~a display pro~ram memory ~1 for
previously storing therein processing comm~nds to the
c~ntral controller 1 in the ~orm of a progra~ to realize

-23-
1 334866
I~ memory 54 ~s well as the auxiliary data to be
r~gistered in the auxiliary da~a ~emor~ 55 are ente~ed
throu~h the ~ey~oard 21 with the help of, for example, a
suitable guide display on the screen of the displa~ ~2
r~spe~tively as the caller subscriber number o the
auxiliary data to be transferred for automatic display and
as, the~ specific ch~acter data~ When a plurality of s~ch
caller numbers and ~ plurality of such auxiliary d~ta are
re~gistered respectively for the same data to be
transferred, these call~ subscriber numbe~s and a~xiliary
data ~or the same dat~ are stored in the memories 54 and
a~ associated with eaçh other in predetermined
r~lationship, for ex~mple, by using the same or ass~ci~ted
a~dre~s data.
Shown in Fiq. 4 is an example of the operstion of the
embodiment app~ratus based on the func~ion (in particular,
a program registered in the above auxiliary data display
progr~m memory 51) of the second e~pansion part 5~. The
auxili.ary da~a automatic display me~hanism of ~he
apparcltus of the s2cond embodiment will be det~iled with
refer~nce to Fig. 4.
Assume now that another communi~a~ion terminal (not
shown f~csimile machine) connected to the ISDN issued a
signal to the second embodiment ~pparat~s shown in Fig. 3.
Then the caller communication terminal fi~st sends to ~he
ISDN ~ signal for calli~g the sec~nd emb~Aiment apparatus
twhich signal is referred ~o as the calling sign~ he
~lling signal usually con~ains a data indicative of a
-a~t-
: . ~, .;
.
- 1 334866
cealler subs~riber number previously designated to the
sign~originator (caller? communica~io~ terminal.
l'he calling signal thus sent to the IS~N from the
caller commu~ication terminal is recei~ed as an incoming
call ~ignal ~t the network controller 11 of the embodiment
apparatus through the ISDN line (D channel).
l'he second embodiment apparatus, when receiving the
incomi.ng ~all sign~l at the network controller 11 and
recogniæing the presence of the incomlng signal at the
cent~cll ~ontroll~r 1 (step 201 in Fig~ 4), starts its
processing i~ the following manner.
~ 1) The central controller 1, when r~cogni2ing the
presence of ~he incoming signal on the basis of a
notifi~cation ~om the ngtwork controller 11, check~
throu~h the network ~ontroller 11 whether or n~t the
incoming signal contains the ~alle~ subs~iber number of
the c~ller communication terminal (step 202 in Fig. 4)~
~ Z) When having determined that the caller subscriber
number is no~ included i.n ths i~coming signal, the central
contrc~ller 1 controls the em~odiment apparatus ~o perform
its u~;ual incoming-signal informing operation~step 203 in
Fi.q. d,)~
~ 3) When d~termining (~n step 202 in Fig. 4) th~t the
cellle~ su~s~riber number is in~luded in the incoming
si.gnal, the central c~ntroller 1 ca~seC the ~egister
contr~ller 53 to se~ (store) the included caller
subccriber number in the ID ~egister 52 (s~ep 204 in ~ig.
4). At this time, if another caller subscriber number
-25-
1 334866
(corre~sponding to the previous incoming signal) is already
set in the I~ reqister 52, then the previous caller
su~scriber number i~ replaced by the new one for its
renewal, unless the ID reqister 52 ~s cleared each time
the processing is completed.
(4) The central controller 1 next checks ~hether or not
~he c~ller subsc~iber number for ~pecifyin~ the caller is
p~eviou~ly registered in the caller ID ~emory 54 (step 205
in Fic~. 4).
~5) 'rhe controller 1, when dete~mining ~ha~ the caller
subscribe~ number is not registered, control the
embodiment app~ratus t~ displa~ the subscriber ~um~er o~
the incoming signal, i.e., the subscriber number set in
~he r~ register 52 on the displ~y 22 through the console
contrc)ller ~ (step 206 in Fig. 4) and subsequently to
pe~rfoTm i~ usual incomin~-signal i~forming operation as
i~ th~! above processinc~ (2) ~step 203 in ~ig. 4).
~6) The controller 1, when determing that the caller
subscriber number included in the incoming signal is
regist;ered in the caller ID memory 54 (step ~5 in Fig~
4)~ reads out associated one of the caller subscriber
numbers from the caller ID mo~ y 54 thro~h the memory
contrc~ller 56 and compa~es the read subscriber number with
the s-lbscriber number set in the ~ register 52 (step 207
in Fi~. 4).
(7~ When determining to be a none-coincidence in
subscriber numbe~ as the comparison result (step 207 in
Fig. 4), the central controller 1 repe~ts the a~o~e
-a6-
1 334866
processing (6)(step 207 in ~ig. 4) so long as other caller
s~bscriber numbers are registered in the caller ID memory
54 (step ~Og in Fig. 4). When the central controller 1
determines th~t an~ one of the subscriber num~ers
registered in the caller ID memory 54 does not coincide
with ~he su~scriber number set in the ~D register 52, the
controller 1 ~ontrols the embodi~ent apparatus to display
the subscriber numbe~ set in the ID registe~ 52 on ~he
displ~y ~ through the console controller a3 (step 206 in
Fiq. 4) ~nd sub~equently to perform its usual incoming-
signal informing operation as in the above processing (5)
(step 203 in Fig. 4)~
~) When determining through the comparison (step 207 in
Fig. 4) to be a subscriber number coincidence (step 20B in
Fig. 4), ~h~ ~entral controller 1 reads o~t throu~h the
~e~o~y controller 5~ the a~xiliary data of the s~scriber
~egistered in the auxiliary d~2 memory 55 ~s associated
with the coincided subscriber number (step 20~ in Fig. 4).
Subs~quently, the central controller 1 controls the
present embodiment apparatus to also display the
subscriber number set in the ID register S2 on the display
22 through the consol~ controller 23 as in ~he abov~
processin~ (S) (step 206 in Fig. ~) and then to perform
its incoming-signal in~orming operation (step 203 in Fig.
4).
7'hrough the above p~ocessings of the app~ratus of the
second embodiment, the business tile and name of the
~ller s~bscriber as well ~s a note on the subscirber can
-a7 -
1 334866
be automatiçally indicated on the display 2simultaneously wit~ the reception of the in~oming ~allr
~g ~ r-esult, there can ~e eliminated such ~n inconvenience
th~t ~,h~ party c~n be confirmed only after the ~pp~r~tuC
has received the tra~sac~ion data, i.e., only after the
apparatus has been put in its communi~ation sta~e, thus
realizing the smoo~he~ ope~tion o the incoming-~all
processing.
The second embodiment apparatus is substantially the
s~me ~s the first em~odim~nt apparatus shown in Fig. 1
with respect to the following points~
~ The reading control system of these subscriber numbers
th~ough the memory controller 56 is not restricted to the
aforementioned system but may be arbitra~ily employed so

~ One or both of the caller ~ memory ~4 and the
auxili~ry data memory 55 may comprise such an external
memory freely detachable from the body of the
communic~tion terminal appa~atus (~a~si~il e machine) as an
~C card.
~ ig. 5 shows a third embodiment of the communicati~n
terminal apparatus of the present invention, even in which
em~odiment the app~r~tus is also intended to be a
-2X-

facsimile m~chine connected to the ISDN, as in ~he first
embodiment~
The apparatus of thè third embodiment, as shown in
Fig. ~, comprises, as ~ whole, a central controller 1 for
perfo~ming general control over the embodiment apparat~s,
a picture memory ~ for temporarily storing therein picture
data as necessary u~der control of the central controller
1, a communication pa~ 10 for per~orming mainly oontrol
and p~ocessing on the communication of the embodiment
apparatus, a console part 20 for performing dat~ or

picture processing part 30 for executing such picture
~ro~essing as ~eadin~ or w~iting a picture data as the
fa.~simile machine, and a third expan~ion part 6~ for
r~alizing operational-mode automati~ selection pro~ssing
of th~ third embodiment apparatus to be detailed lat~r in
association with the ~unctions of these part~ 1, 10, 20
~nd 30~ The par~s othe~ than the third expansion part 60
are the same as those in th~ first embodiment app~ratus of
Fig. 1 or those in the second embodiment appar~us of Fig~
3 ~nd th~s the following explanation will be concentra~ed
orl the arrangement and function of the third e~pansion
p~r~ ~0.
As shown in Flg. 5, the thi~d expansion part 60
includes a mode autom~tic selection program memory 61 fo~
pre~i~usly storing therein processing comm~nds to the
centr~l çontroller 1 in the form of a program to realize
an operational-mode automatic selection pFocessing to be
-29-
,
1 334866
explained later, an ~D register 62 for tem~ora~ily s~orin~
therein a caller subscriber number and/o~ a ~ubaddres~
when an incomin~ signal received ~t ~he communicatio~ part
10 contains the subscriber number and its subaddress as an
identification data ID, a register controller 63 for
controlling the reading and wri~ing operations of the data
(number) of the I~ ~egister 62 on the basis of commands
from t;he central controller ~, a caller I~ memory 64 for
previously registering therein a single or a plurality of
caller subscriber numbe~s as identi~ic~tion data IDs
cpecifying associated caller communication te~minals and a
single or a plurality of subaddresses as identific~tion
data I~s speçi~ng the spe~ified communication terminals
and the selected operation~l modes, an operational mode
~emory 65 for previoucly registering therein data
indicative of the operational modes sele~table in the own
cc~mmunication termin~l (present embodiment apparatus) in
associ.ation with the subaddresses (in the pres~nt
e~bodiment, only a part thereof), and a memory controller
66 for controlling the reading ~nd writing oper~tionC of
the data o~ these memories ~4 and 65 in ~ordance with
commands from the central controller 1.
~ xplanation will next be mad~ as to relationships
b~twe~n the subscriber numbers and su~addresses as their
acldtional data and as to relationship between the
subaddresses and the asso~iated operational modes,
respectively by referring to Figs. 6 a~d 7.
'~he subscriber number, as shown in Fi~. 6(a), is an
- 30 -
1 334866
identii~ation number data of a predetermined length
previously designa~ed ~o one of su~s~ribers for the
communiçat~on network. In othç~ words, the use~ cannot
change the subscriber num~er freel~.
Meanwhile, the cubaddress is an iden~ification number
data which can be freely determined and set by some
parties among the subscribers of the communication
network~ When an identical subs~riber number is
d0signated to a plurality of communication ter~i~als, the
subaddress is ~sually used, in many appli~ations, a~ a so-
c~lled "t~rminal i~entifica~ion data" to specify one of
the communication te~minals all havin~ the s~me subscriber
number .
To this end, t~e present thi~d embodiment is arranged
so thAt the subaddress is divided, $or exa~ple, as shown
in Fig~ ~(b), into "function identification data" for
specifying one of the set operational modes a~d "terminal
ident.ific~tion data" for specifying one ~f the
communication ~erminals. One of the operation~l modes can
b~ identified, in particular, by the former "function
iden~lfica~ion data".
5hown in Fig. 7 is an ex~mple showing relationships
between the "fun~tion identif~cation data" and associated
operational modes, in whi~h "function identification data"
01 specif.ies "relay multiple ~ddre~s" as an operational
mode, "function identi~ication data" 02 specifies "remote
multi-copy" as an oper~tional mode,..., and ~o on. That
i~, the ~hird embodiment app~atus is intended, when a~
31-
1 334866
operational mode is specified b~ "function identiication
data" in the sub~ddress in this w~, to identify and
~utomatica:Lly execute the specified operatio~al mode.
The subscriber n~mber ~nd its subaddress to be
reqistered in the calle~ ID memory 64 ~re entered throuqh
operator's keybo2rd 21 with the help of, e~g., ~ suita~le
g~ide indication on the screen of the display 22 in such
fc,rmat.s as shown in Fig. 6(a~ and ~b) in the form of
number data which specify a caller communication terminal
~ap~le of specifyin~ ~he shif~ of the emb~dimen~
apparatus to such operational mode, the ~ase comm~nica~ion
t~r~inal (the presen~ embodiment app~ratus) ~nd the
operational mode the embodiment app2ratus can
a~tomatically exec~te respectively. The operational mode
d21ta t;o be regtsterçd in the op~ra~io~ mode memory 6~ ls
also enterd throu~h the keyboard 21 with the help of,
e.g., a s~itble guide ind~cation on ~he s~reen of the
di.splay 22 in su~h a format as shown in Fi~. 7 in the form
o~ a d~ta indicative of thç operational mode placed at the
"iunc~ion identification data~ of the subaddress. When a
plu~:Lity of such identification data and a plur~lit~ of
such oper~ional modes are registered, the identification
data :rD (subscriber number and subaddress~ and operatio~al
mode data are stored in the memories 54 and 55 in
predete~mined relationships with each other, or ex~mple,
b~ using an identical or associated address data for the
subscriber and its operational mode~
Fig. 8 shows an example of the operation of the
- 3~--
.
1 334866
present embodiment apparatus based on the function (in
particular, a program re~istered in the aorementioned
mo~e automatic-selection program memory 61) of the third
expansion part 60. The operationa~-mode automatic-
selection mechanism of the third embodiment a~paratus will
be detail~d in the followin~iby ~eferring to Fig. 8.
Assume now that another communi~ation terminal (not
shown facsimile machine) connected to the ISDN issued a
signal to the third embodiment appar~tus shown in ~i~. 5~
Then the caller communication te~minsl first sends to the
I5DN a signal for calli.ng the ~hi~d em~odiment apparatus
(which sign~l is referred to as the callin~ signal). The
c~llinq signal usuall~ contains ~ data indicative of a
çaller subscriber numbe~ previously designated to the
signal-originator (caller) communica~ion ~erminal and
subaddress ~s its additional data.
l`he cal~ing signal thus sent to the ISDN from the
caller communic~tion terminal is received ~s an incoming
c~ll signal at the network controller 11 of the embodiment
apparatus ~hrough the ISDN lin~ (D channel).
The t;hird em~odiment apparat~s r when receiving th~
incoming call signal at the network controller 11 and
re~ognizing the presence of the incoming signal at the
central con~roller 1 (step 301 in Fig. 8~, starts its
processing in the following m~nner.
(1) The cent~al controller 1, when re~ognizing the
presence of the incomin~ signal on the basis of a
no~ification from the network controller 11, checks
-33-
- 1 334866
thro~gh the network controller 11 whether or not the
incomlng signal contains the c~ller subscriber number of
the caller communication termin~l (step ~02 in Fig. 8).
(2) When having determined that the caller subscriber
number is not included in the incoming signal, the central
controller 1 controls the embodiment apparatus to perfor~
its usual incoming-signal pro~es-cin~ operation ~step 3~3
in Fig. 8). In this case, the setting of the control
conditions is arbitrary ~nd of course, the central
can~roller 1 ma~ control the e~bodiment apparatus to
select and perform an incoming-signal reje~tion processing
to be expl~ined 1ater (step 309 in Fig. 8).
~ hen determining ~in step 302 in Fig. 8~ that the
caller subs~ribe~ number is included in the incoming
signal, the central controller 1 causes the register
controller 63 to set (s~ore) the included caller
su~scriber number in the I~ re~ister 6Z ~step 304 in Fig.
8). At this time, if ano~her caller subsc~iber number
(corresponding to th~ previous incoming sign~l) is Already
s~t in the ID register 62, then the previous caller
subscriber num~er is replaced b~ the new one for its
r~newal, unle~s the ID ~egi~ter 62 is cle~red ea~h time
the processing is completed. Furthsr, i~ the subscriber
n~ber o the incoming siqnal is attached with a
su~address, then the subaddress is also set in the ID
register 62
(4) The centr~l cont~oller 1 next checks ~hether or ~o~
c~ller s~bscriber number ~or specifying the caller i5

1 334866
p~e~iously re~istered in the caller I~ memory 64 (step 305
in Fig. a)~
(5) The cont~oller 1, when determining that th~ caller
subscriber number is no~ re~iste~ed, control the
embodiment apparatus to perform its usual incomin~-signal
processing operation as in the above processing (2) (step
303 in Fig~ 8).
(6) The controller 1, when determing ~h~t the caller
subscriber number included in the incoming signal is
registered in the caller I~ memory 64 (step 305 in Fig.
8), reads o~t associa~ed one of the caller su~sc~iber
numbers from the caller I~ memory 64 through the memory
controller 66 and compares the read subscriber number wi~h
the subscr:iber number set in the ID register 62 (step 306
in Fig. 8)~
(7) When determinin~ to be a none coincidence in
subscriber num~er as the comparisan recult ~step 3~7 in
Fig~ 8), the central controller 1 repeats the above
processing ~6) (step 306 in ~ig. 8) so lon~ as other
caller subscriber n~mbers ~re registered in the caller I~
memory 64 (step 308 in Fig. ~). When the central
controller 1 determines that any one of the subscriber
numbers regis~red in the ~allçr ID memor~ 64 does not
coincide with the subscriber number set in the ID regts~er
6~, the controller 1 controls the embo~iment apparatus to
~o perform a usual incoming-signa~ rejection p~cessing
(step 309 in Fig. 8).
~ 8) When determining throu~h the comparisan (step 306 in
-35-
- 1 334866
Fig. g) to be a subsc~lber num~er coi~cidence (step 3~7 in
Fig. ~), the central controller 1 then makes reference to
the contents of the I~ register 62 and checks whether or
not the subscri~er number is attached with a subaddress
(s-tep 310 in Fig. 8).
~ g) ~he controller 1, when determining thro~gh the check
that any subaddress is not att~ched to the s~bscriber
n~m~er, also controls the embodiment apparakus to per~or~
it.s ~su~l incoming-signal processingoperation ~s in the
a~ove processing (2) or (~ tep 303 in Fig. 8~.
l~O) When d~termining through the comparison (s~ep 310 in
Fig. 8) th~t a subadd~ess i~ attached to the subscri~er
number, the central controller 1 further reads ou~ through
the memc~ry controller 66 the base terminal subaddress
registered in the caller ~D memory 64 as associated with
the coincided subscriber number, and checks whether or not
the read subaddress coinçides with the subaddress being
s~t in the ~D register 62 (step 311 in Fig. 8).
~ 11) As the ~esult of the check, if the con~roller 1
determines to be a subaddress coincidence, then it
con~rc)ls the em~odiment apparatus to perform its incoming-
signa]. rejecting operation as in the above processin~ (7)
(step 3~ in Fig. a).
~ 12) The central ~ont~olle~ 1, when determining through
the above check (step 311 in Fig. a) to be a subaddress
coinci.dence, first performs its incoming-sign~l processin~
operat;ion ~n accordance with the predetermi~ed
tr-~ns~ission control procedur~ (st~p 312 in Fig. 8), re~ds

out through the memory controller ~6 one o~ the
opexational mode d~ta registered in the operational-m~de
me!mory 6S and correspondinq to the "function

contr~ls the present embo~iment apparatus to be
autom~ically shifted to the operational mode indicative
o~ th,~ re~d-out oper~tional-mode data (s~ep 313 in Fig.

1'he above processing of the third embodiment
appar~tus en~bles the reali~-2t~0n of remote ~ontrol of ~he
~hird embodimen~ apparatus through a control terminal or
specific relay co~munication terminal (regist~red in the
c~ller ID memory 64). That is, so long as arbitrary
numbers and d~ta a~e p~eviously registered in the caller
I~ me~or~ 64 and the oper~tional-mode memory ~5, all the
proce~:sing of the registered operational modes can be
autom~l~ically attained throu~h the communication terminals
havint~ ~hese registered numbers, even if any operator is
absenl. at ~he embodiment apparatus, thereby realizinq more
flexible and efficient utiliza~ion of these communication
t~rminals~ In addition, since such rgmote control is
effected independentl~ o$ the communication protocol, the
operat~ional-mode automati~-selection processing of this
embod.~ment .is gener~lly valid even o~ c~mmunication
t;erminals that are man~factured b~ different makers and
~perat.ed a~cording to different communication protocols.
rrhe above operational-mode automa~ic-selection
proce:3sing has been carried out only when not only the
1 334866
su~scrlber number but also its subaddress coin~ides with
the registered one as shown by step -~11 (the above
p~ocessing (10)) in the ~oregoing embodiment based on the
operat.~onal example shown in Fig. 8. However, such
processing as shown, for e~ample, in Fig. q ~ay al~o be
employed. That i5, when the central controller
deternlines to be a subscrib~r number ~oincidence (step 307
in Fig. 9) and there is a s~baddrsss in the incoming
sig~al (step 310 in Fig. g), the controller performs its
incomi.ng-sig~l processing operation in accordance ~ith
the predetermined tr~nsmi~sion control procedure (step 312
in Fi~ nd subse~uently if the operational mode data
correspondin~ to the "function ide~tificatlon data" in the
subaddress is ~lre~dy re~istered in the operational mode
memory 65, then the controller 1 rea~s out throu~h the
m~mory cont~oller 66 the registered operational-mode data
and ~ontrols the present embofl~nt apparatus to be
auto~tically shifted to the oper~tional mode indicative
of the read-out operational-mode data (step 314 in Fig.

en~odiment apparatus to be detailed later in association
wi.~h 1:he functions of these parts 1, 10, 20 and 30. The
parts other than the fourth e~pansion part 70 are the same
as those in the foreqoin~ e~bodiment apparatuses and thus
- 39 -
1 334866
the following expla~at.ion will ~e co~c~ntrated on the
arrangement and funl~tion of ~he fourth expansion part 70.
As shown in Flg. 10, the four~h expansion part 70
includes a return-messa~e t~ansfer progr~m memory 71 for
previc~sly sto~ing therein p~ocessing commands to ~he
central controller 1 in the form of a proqram to realize
an operation~l-mode automatic selection processing to be
explai.ned later, ;~n ID register 72 for temporarily storing
therein a caller subsc~iber nu~ber when an incoming si~nal
r~celved at the communicati~n part 1~ contains ~he
subsct iber num~er as an identification data ID, a register
c~ntroller 73 for ~ontrolling the readinq and writing
operat;ions of the d~ta (number~ of the ID re~ister 72 on
the basis of commands from ~he central controller 1, a
celller ID memory 74 for further temporrily ~toring and
regist;erin~ ~herein the subscri~er number (ide~tification
delt~ r~) that was received when the embodiment apparatus
is pu~ in its com~unication disable state, i.e., that was
temporarily stored in the ~D register 72, a ~emory
controller 75 for controlling the reading and writing
operat:ions of the data of these memories 74 in accordance
wi.~h commands from the central cont~oller 1, a message
memory 76 for previously s~oring therein su~h a document
data :Lndicative of a return message ~s sho~n, fo~ example,
in Fig. 11, and a recordin~ paper sensor 77 disp~sed in
~he recor~er 35 for always detecting the presence or
absence of an out-o- reco~ding-paper state.
With such a return me-~sage as shown in FIg. 11, its
-~0 -
-- 1 334866
de~scription matters are entered through the keyboard 21,
fc,r e~ample, under a suitable guide indication on the
screen o~ the display 22 and its time description matter,
ir, particular, is automatically listed through the central
contr~ller 1 (usually incorporating a timer) during the
tr~nsmission of ~he return message.
~ 'ig. 12 shows an example of the operation of the
present embodiment apparatus based on the function (in
p~rti~:ular, a program registered in ~he aforementioned
return-mess~ge transfer program memory 71) of the fourth
exp~n~ion par~ 70. The return-message transfer mechanism
of the f~urth embodiment apparatus will be detailed in the
f~llowing by referring to Fiq. 1~.
Assume now that another communication terminal ~not
shown facsimile machine) connected to the ISDN issued a
si.~nal to the fourth embodiment apparatus shown in Fig.
10. Then the caller comm~nic~tion terminal firs~ sends to
the ISDN a signal for calling the fourth embodiment
appar~tus (which signal is referred to as the calling
si.gnal)~ The c~lling signal usually contains ~ data
ir~dicative of a caller subsçriber number previou~ly
designated to the signal-originator (caller) communi~ation
termin~l.
'rhe calling signal thus sent to the ~S~ from the
caller communication terminal is received as an ~ncoming
call signal at the netw~rk controller 11 of the embodiment
apparatus through the ISDN line ~ ~hannel).
~e~nwhile, the central ~ontroller 1 is executing a
-41-
1 334866
normal façsimile operatio~ routine under ~he conditionths~ the detection ~utput of the reco~ding~paper se~sor
77does not indicate ~n out-of-reco~ding-paper state ~s~eps
401 and 402 in Fig. 1~). Under such a condition, if ~he
çmbodiment appa~atus receives the above incomin~-~all
sign~, then the central controlle~ 1 controls ~he
e~odi.me~t apparatus to pe~crm its normal incoming-call
a~swering operation. In this case, a pic~ure data
transmitt~d on the inco~ing-call signa~ is sui~ably
demodula~ed th~ough the communication ~ontroller 12,
trans~e~re~ to the picture buffer pro~essor 37, and then
re!corded on a re~ording paper through the recorder 35.
Under the condition that the dete~tion output of the
r~!cording-paper se~so~ 77 indic~tes an out-of-paper state,
i.e., that the embodimen~ apparatu~ (facsimile ~achine) is
put in its c~mmunication disable state, on ~he other h~nd,
if the netwo~k controller 11 receives the in~oming-call
signal. as mentioned a~ove, then the fourth embodiment
apparatus starts the following processing operatlons in
sequerlce on the b2sis of the determin~tion of pre~en~e of
the incoming si~nal by the central ~ontroller 1 (step 403
in FIg. 1~ the case of the detection of such an
out-oi-p~per state, ~he central controller 1 also informs
the operator of the out-of-pape~ by means of, for example,
an o~t-of~paper message indicated on the display Z2
th~ou~h the console controller 23, where~y the opera~or
can quickly condu~t such resto~i~g work as recording-paper
supplemen~ o~ the ~asis of such message displ~.
~a-
- 1 334866
In parallel w~th the abo~e operator's work, ~he
fourth embodiment apparatus carries out the following
processinys.
(1) The central controller 1, when determing the presence
of th~ incoming signal on the basis o the notification
from the network controller 11, further determines throu~h
the netowork controller 11 ~he inclusion o$ the subscriber
number of the ~aller communication terminal in the
incoming-call signal ~nd sets (stores) through the
register controller 73 the caller subscriber number in the
regis~er 72 (step 404 in Fig. 12). In this connection, if
another subscriber number (whi~h is an old subscriber
number included in the pre~ious incomin~-call signal) is
already set in the ID re~ister 72, then the old subscriber
num~er is updated to this newly receive~ one, except that
the memory o~ the I~ re~ister 72 is cleared each time the
procescing is completed.
(2) The ~ntral controller 1 th~n s~ores ~nd registers
the çaller subscriber number set in the l~ re~ister 7~
int~ the caller I~ memory 74 ~hrough the memory controller
7S (step 405 in Fig. 12).
(3) ~ring the above oper~tion, the central cont~oller 1
is continuously monitoring whether or not ~he operator' 5
restoring work h~s been completed on the basis of ~he
detection output of ~he recording-paper sensor 77 or an
ope~tor's work-completion report throu~h the keyboard ~t.
At the same time, the ~ontroller 1 chec~s whether or not
th.e embodiment apparatus is ln a communication able state
- ~3 ~
1 334866
or signal reception able state (step 4~6 in Fig. 12).
~urlng the communication dis~b~e state of the embodiment
apparatus, if the apparatus receiv~ a plurality of
in.comi.ng call signals from a plu~ality of callers, then it
repeates the above p~ocessings (1) and (2) for each
recept.ion of the incoming signals and registers a
plurality of sub~criber numbers of the plurality of
callers in the caller ID memory 74.
~4) The central cont~oller 1, when determing to be ~
signal-reception a~le st~te (step 406 in Fig~ 12), reads
out under the memo~y controller 75 the s~bscriber numbers
regist;ered in the ~aller Il:) memory 74 on a one-after-one
basis and performs its ~alling p~ocessin~ over the read-
out subscriber number through ~he communication part 10.
The central cont~oller 1, after being put in its da~a-
transaction enable state with respect to ~he party
(called~party or ~ll-receiver) ~ommunication terminal
(facsimile machine), reads ou~ the associa~ed return-
messa~e data from the message memory 76 and transmits i~
to the party communication ~erminal newly put in th~
commurlic.~tion state ~st~p 407 in Fig. 12~.
Throu~h ~he above processings of the fo~rth
embodiment apparatus, the re~urn message thus tr2nsmitted
can be received and reco~ded in the new party
communication terminal (facsimile machine) through a usual
operational rou~ine. Thereore, the party communic~tion
terminal can im~ediately know, on the ~asis of ~he
r~ceived and recorded message, that ~he presen~ e~bodiment

1 334866
apparatus has been returned to the communication ~ble
state and thus it can a~ain c~ll the present embodiment
appar~tus at any time t~ere~fter~ Wi~h respe~t to this
point, the present embodimont apparatus can reduce useless
ope~ations and waiting time to a large extent, when
compared with the prior art which re~uires requent
calling o~e~a~lons wi~hout k~o~ing its restoration time,
whereby the operator can comfortably communi~ate with the
party wi~hout causing ~ny irritatin~ feelin~.
Thouq~ explAnation has been made, ~or brevity of
explanation, as to only the case where ~he apparatus is
put in the communication disable st~te when it is out of
r~cording-paper in the foregoing embodi~ent, it will of
course be noted that the present invention is not limit~d
t~ ~he specific e~bodiment but may be arranged so that th~
~c~mmunication disable state of the ~ppa~atus is caused by
o~her fa~tors such as a busy state in a copyin~ mode and
so on, in addition to the above out-of-paper state.
The transfer service af the above return mess~ge h~s
been car~ied out with respect to callers so long as the
caller subscriber numbers are included in the respective
incoming signals from the callers in the o~egoing
embodiment~ ~o~eve~, the pressnt embodlment m~y also ~e
modifi.ed so that particular c~ller su~scriber numbers are

realizing incoming-sgin~l condition c~nt~ol or managemen~
to be detailed lat~r in ass~ciation with the functions of
these parts 1, 10, 20 and 3~. The parts o~her ~han th~
fifth expansion part 8~ are the same as ~hose in ~he
foregoing embodiment apparatuses and thus the $ollowing
explanation will be con~entrated on ~he a~ran~ement ~nd

As shown in ~ig. 13, the fifth expansion p~rt 80
includes an incoming~si~nal-~ondi~ion management program

w~iting operations of the data o~ the memory 84 in
accordance with commands from the ccntral controller 1, a

setter 87 for setting or resetting a flag ~ an index for
the :incomin~ signal condition managemen~ under the
predetermined ~ont~ol of the central controller 1.
The subscriber number or numbers to be re~istered in
the caller ID memory ~4 is entered as necessary through
th.e keyboard 21 with the help of, for example, a suitable
guide indi~ation on the screen of the display 2~, as a
single or a pl~rality of specific caller subscriber
numbers on the basis of which the assoGiated incoming
signa]s are granted or re~ected. Further, the timer time

Fig. 15 shows an example of the operation of the
present embodiment appa~atus b~sed on the function (in
particularr a program registered in the a~orementioned
incoming-s:ignal condition man~gement program memory 81) o~
the fifth expansion part 80 . The incoming-signal
condition man~gement mechanism of the fifth embodim~nt
appara~s will be de~ailed in the ~ollowing by referring
t~ . 15~
~ ssume now that another communic~tion terminal (not
shown facsimile mac~ine) con~ected to the ISDN issued a
slgna~ to ~he fifth embodiment appara~us shown in Fig. 13.
Then the caller communication termin~l first sends to the
ISDN a signal for calling the fi~th embodiment apparatus
(which signal is refer~ed to as the ca1ling signal). The
calling si.gnal usual~y contains a data indicativç ~f a
caller subs~riber number previously designated to the
signal-originator (caller~ co~munication terminal.
I`he calling signal thus sent to the IS~N from the
czller commu~ic~tion terminal is received as an incoming
call signal at the ne~work cont~olle~ 11 o~ the embodimen~
apparatus ~hrough the IS~N line (D ~hannel).
The fi~th em~od1~nt apparatus, ~hen receivinq the
incoming ~all signal at the network con~roller 11 and
rec~gnizing the presence o~ the incoming signal at ~he
c~ntral cont~ller 1 (step 511 in Fig~ 15), starts its
processin~ in the ollowing m~nner~
~1) The centr~l controller 1, when dete~mining the
presence of the incoming signal on the basis o~ an
_ ~9 _
- 1 334866
incoming-s;ignal notification from the network controller
11, first che~ks whether or not the fl~g setter 87 is in
its set st~te tstep 512 in Fig. 15).
(~) When determining through the check that the fla~
setter 87 is not set, the central controller 1 cont~ols
the present embodiment apparatus to perform its usual
incoming-signal processing ~per~tion (step 513 in Fi~.
15).
~ 3) If determining through the check (step 512 in ~ig.
1~) that the flag setter 87 is set, then the central
controller 1 j~dges thro~gh the ne~work controller 11
whether or not the subscriber number of the caller
c~mmunication terminal is included in the incoming signal
(~tep 514 in Fig. 15).
~ 4J When determining that the caller subscriber nu~ber is
not in~luded in the incoming signal, the Gentral
controller 1 controls the embodiment apparatus ~o perform
its incoming-signal rejeçtin~ oper~tion to r~ject the
~eception of th~ incoming signal tstep 515 in ~ig. 15).
(S) When determinin~ through the judgement (step ~14 in
Fig. 15) t.hat the calle~ su~scri~er number is included in
the incoming sign~l, the central controller 1 causes the
r~gister eont~oller 83 to set (store) the included caller
subs~riber number in the I~ register 82 (step S16 in Fig~
15). At this time, if ano~her caller subs~riber number
(corresponding to ~he previous incoming signal) i~ already
set in the I~ ~egister 82, then the previous call~r
subscriber number is repl~ced ~y the new one for its
- 50-
-- 1 3 3 4 8 66 rene~al, ~nless the ID register 82 is cleared each time
the processing is completed. Further, if ~he subscriber
number of the incoming signal is attached with a
subaddress, then the subaddress is also set in the ID
register 6~.
(6) The ~ntral controller 1 then ~eads out one of ~h~
subs~riber numbers from the caller ID memory 84 through
the memory cont~oller ~S and collates or compares the
read-out subscriber number with that set in the ID
regis~er 82 (step 517 in Fig. 15)~
~ 7) When determining to be a none-coincidence in
subscriber number as the comparison result (step 5t8 in
Fig. 15), the central controller 1 repeats the a~ove
processing ~6) (step 517 in Fig. 15) so long as other
caller subscriber numbers are registered in the ~aller I~
memory 84 (step ~19 in ~ig. 1~). When the c~ntral
controller 1 determines that any one of the subscriber
n~ers registered in the caller I~ memory 84 does not
coincide with ~he subscriber number set in the I~ register
8~, the controller 1 controls the embo~i~en~ app~r~us to
perform the incoming-signal reje~ting operation (step 515
in Fig. 15) as in the above processing (4).
t8) When determining through the comp~rison ~step 517 in
Fi.g. 15) to be a su~scriber number coincidence (step 518
in Fig. 15), the central controller 1 determines that it
is data transmission from the caller for which the
apparatus accepts its incomi~ signal and controls the
present embodiment apparatus to perform its usual
-5~ -
1 334866
.
incoming-sign~l processing ope~ation (step 513 in Fi~.
1$).
In this way, through the abo~e processings of the
fifth embodiment apparatu~, the app~ratus can
automatically execute its incoming sign~l processing
operation unde~ dif$erent conditions (A-1) and (A-2) that
the flag setter 87 is set o~ not as fo~lows.
~ -1) Wh~n the flag of the flag setter 87 is set, that
is, when the parti~ular subscribe~ n~mber on the ~aller is
previously registered and the timer time is effective, the
en1bodlment appa~tus answers to the call only from the
registered subscriber and per~o~ms the incoming-signal
p~ocessing operation in response ~o the incoming call
while re~ects for calls from the other subscriber-~ not
registered.
~ A 2) If the flag is not set, the embodiment apparatus
answers to cal1s even from any s~bscribers and performs
the incoming-~ignal processing oper~ion, ~hat ~s, the
apparatus is put in an open sta~e to all the subscribers~
~ ccordin~ly, the modification of the incoming-signal
conditions to, e.g."the apparatus recei~es data (pic~ure
data) only from company A d~ g one hour ~lone and then
accepts all d~ta received thereafterN can be freely
realized e~en in ~he absence of any operat~r, ~o long as
the aforementioned settin~ for the caller ID memor~ 84 and
t:imer 86 is previously effected a~ necessary.
In the foregoing embodiment, the above incoming-
signal condition (A-1) or (A-2) has been set a~cording to
-52 -
1 334866
the p~esence or absence of the setting of the ~lag -~etter
a7, but the present inve~tion is not restricted to the
particular example~ For example, when the incoming-signal
~ondition control program for the memory 81 is set to
cause such operation as shown in Fi~. 16, the present
appar~tus may similarly operate as follows depending on
the presen~e o~ absen~e of the settin~ of the flag setter
87.
~B-1) When the flag oi the flag setter 87 is set, that
is, when the partic~l~r subscrlber n~mber o~ the caller ls
previously regi.st~red and the timer time is effective, the
embodiment apparatus answers to the call only ~rom ~he
r~!gistered subscriber and performs the incoming-signal
pro~essing operation in response to the incoming call
~hile re.jects fo~ calls from the other subscribers not
registered.
~B-~) If the flag is ~ot set, the em~odiment apparatus
r~jects incoming signals rom any subscribers, that is,
the appar~tus is put in a closed state t~ all th~
subs~ribers.
For example, when the incoming-signal condition contxol
pro~ram fo~ the mem~ry 81 i5 also set ~o caus~ su~h
operation ~s shown in Fig. t6, the present apparatus may
si.milarly oper~t~ as follows depending on the presence or
ahsence of the settin~ of th~ $1ag setter 87.
~C-1) Wh~n the flag of the flag setter 87 is set, that
i~;, when the particul~r su~scriber nu~ber on ~he calle~ is
previously registered and ~he timer time is effective, the

- 1 334866
embodiment apparatus rejects the recep~ion of an incomin~
call only from the re~istered subscriber while normally
answers to calls from the othe~ subscri~er-q not registered
and p~rforms its incoming-si~nal processing opera~ion.
(C-2) If the fla~ is not set, the embodiment apparatus
r~jects incoming si~na1s from any subscri~ers, that is,
the apparatus is put in ~ closed state to ~ll the
subscribe~s~
F~ther, when ~he incoming-signal con~ition control
program for the memory 81 is ~et tR cause such operation
as shown in Fig. 16, the present ap~ara~us ma~ similarly
operate as follow~ depending on the presence or ~bsence of
the ~etting of the flag setter 87.
~ D-1) When the flag of the flag setter 87 is set, ~hat
i-c~, when the particular subscribe~ num~er on ~he ~aller is
pre~iously reglstered and the ti~er time is effec~ive, the
embodiment apparatus re~ects the reception of an incoming
call only f~om the registered subscriber while normally
answers to c~lls from the othe~ s~bscribers not regis~ered
~nd performs its incoming-signal processing opera~ion.
(~-2) If the flag is not set, the embodiment apparatus
answers to ~ncoming signals from any subsc~ibers and
perform the incoming-signal processing operation, that is,
the ~pparatus i~ put in an open st~te to all the
subscribers. It goes without saying ~hat these incoming-
s:Lgnal condition con~rol programs may be previousl~
prepared to be selected fr~ely as necessary~
Although the timer 86 has been provided and the flag
. - 5~ -
1 334866
setter 87 has been set on th~ A~D condition that ~he
subscriber number is p~e~iously registered in the caller
I~ memory 8~ and that ~he timer ~ime i5 previously set in
the ~imer 86 in the foregoin~ fif~h apparatus shown in
Fig. 13, the provision of the ti~er ~6 is not the
essential requirement of the fifth embodiment. In other
wc,rds, the 1ag setter a7 may also be set only under such
condition that the subscriber num~e~ is previously
r~gis~ered in the caller ~ memory 84.
Although the communication netw~rk has been intended
to be the IS~N and the ~pparatus has been intended to be a
facsimile ma~hine in ~ny of the foregoing first ~o fif~h
embodiments, the communication terminal appa~atus of the
pl~esent invention is, as a matter of course, no~
r~stricted to these particular ISDN and fscsimile machine
but a telephone set, a telex equipment or so on other than
the facsi~lile machine may be emplo~ed, in pa~ ular, as
the commu~ication terminal.
The dif~erent ~unctions o the communi~ation terminal
apparatuses in a~cordance with the present invention have
been illu~rated sepa~ately as the fo~egoing first t~ fi~th
ernbodiments in the foregoin~ explan~tion. However, ~he
respecti~e expansion parts in ~he respective embofli rents
may be arbitrarily selected and combined to more
effe~tively improve ~he user inte~face and communication
effi~ien~y. That is, in actual applications, these
embodiments m~y, o~ course, be utilized in a~bitrary
~ombination ~herebetween as ~exessary.
