Explanation
[1 ] A system can be divided so that a
group of stations (up to 8 groups
maximum) cannot call each other.
[2] Some or all of the stations in the group
can both call and receive calls from all
stations.
[3] One or all (all-call, individual zone,
combination) paging modes can be used
by stations in the group.
Any station can be allowed to access to all
Call, Conference, General Purpose Control

interrupts paging of lower priority.
The lower priority paging is put through
afterwards. Priority is in the
following order: (1) >(2» (3) = (4)
[2] For paging messages wit h equivalent
priority, priority is given to the one initiated first and those initiated after are
put on camp-on-busy.

Personal Number Call
A personal number may be registered at any master station
which the person to whom the number is assigned expects
to be. A party wishing to receive personal number calls at
a specific station may register his number at that station by
touch dialing
Personal Number.
Those who are frequently away from their assigned station,
as well as those who share a sin gle station may be assigned a
"Personal" 4-digit number which may be programmed to
any master station in the system. This personal number,
which is completely independent of station numbers, may
be programmed at any master station, and any previous
programming of that same number at any other station is
automatically cancelled. When the party calling has dialed
the number to which he wishes to speak, the call is then
routed to the station at which the Personal Number was
last registered. The numbers which may be assigned in this
group are 1000 through 1499.
Personal number program cancellation can be done at any
station be merely dialing:
Personal Number
When anyone having a personal number leaves the office, he
merely cancels the programming of his personal number.

Master Sub Relationship
Master/Substation associations are set up by using station
#200 as th e programming station. Once these relationships
have been established, substations can then contact their
designated master stations by simply touch dialing
With respect to this function, the stations in the system are
divided into two categories; master sta tion s and substations.
Any master station can be connected to any other station
in the system. However, substations can initiate calls only
to specific master stations. This is done by single touch
dialing, and will only connect the substation to one specific
master.
Several substations can be programmed under th is stat ion
to connect with a signal specified master station.
To register single digit dialing, touch dial
substation number
Single digit dialing from that master to a specific substation
is t hen accomplished by touch dialing
Programming a master station for Single Digit Dialing of a
substation number under this function is programmed in
the same manner as other sin gle d igit di al in g, and results in
one touch dialing from master to substation.

Secretary Transfer
This function is only available when a specified station is
programmed for this purpose with use of Station #200 in
the programming mode. Automatic transfer of incoming
calls by an executive to his secretary is accomplished by
placing the Privacy Switch on his station in the ON position.
This function allows a secretary to accept all incoming calls
placed to an executive.
For the executive to accept calls directed to his station
once the automatic secretary function has been program-
med by station #200, he simply moves t he privacy switch
to the left, or OFF position.
It is also possible for the executive to accept calls at his
station.
There is no limit to the number of Executive/Secretary
pairings except by the number of available number combinations within a given system.
Secretary
Adoption of the selective function "Transfer" allow rerouting of the call transferred to the secretary back to the
executive's station.
When the secretary answering a call touch dials
executive's station number
the privacy tone sounds continuously at both ends of the
line, while the call is held. The call holding tone is trans-
mitted to the calling station. If the executive shifts the
privacy switch to the left position, he can talk with the
secretary. If the call held is to then be transferred back to
the executive's station, the secreatary is to touch dial [C]
and the original calling station will be connect to the
executive's station.
Touch dial
Executive's station number
at the secretary's station in advance. When the call transferred to the secretary has to be transferred back to the
executive, the secretary simply touch dials
at her station. This sets the privacy tone sounding conti-
nuously at both ends of the line whil e the call is held. If the
call is to be transferred back to the executive's station, the
secretary touch dials
The calling station will then be connected to the executive's
station.
Adoption of the selective functions "Transfer" and "Single
Digit Dialing" allows simple retransfer of the call transferred to the secretary back to the executive's station.
Reply from the executive, the secretary touch dials
This will then return the secretary to the original call.

and asked whether he will accept the call. If he agrees to
accept the call, dial
and the transfer will be completed.
This function allows called party to transfer that call to
another station. The party to whom the call is to be transferred, may be called using either the Station Number, the
Personal Number or through Single Digit Dialing.

Priority
When the party called is on the line, as indicated by the
busy tone, dialing
transmits a priority tone to the called party. The same
tone is audible at the calling station. The call is connected
if the called party also responds by dialing
In this event, the original conversation partner of the party
called is temporarily placed on hold and the holding tone is
transmitted to his station.
Upon completion of the priority conversation, the party
who placed the priority conversation dials
at his station. This allows the interrupted conversation to
resume.
When the called party is already on the line, the party
calling, if he deems it necessary, can send a Priority signal
to the called party. After a response from the party called,
the urgent call is allowed to take priority and go through.

Continuous Calling To ne
When a specified station receives a call, the calling tone
continues until PTT bar is depressed by this party .
1. When calls cannot be answered immediately or when it is
difficult to hear a normal calling tone due to high back-
ground noise, the station should be provided with the
continuous calling tone function. There is no limit to
the number of stations that may be equipped with this
function, but a No.200 registration must be completed
(refer to Installation Instructions for EXES-5000 CPU-
55.)
2. Stations with handset (such as the HFM-500) may
activate the PTT function when the handset is lifted.
3. When the caller depresses the PTT bar while the conti-
nuous calling tone sounds, he can talk to the person
called by one-way. When the PTT bar is released, the
continuous calling tone returns.
4. During two-way conversation, each party presses the
PTT bar to talk and releases the PTT key to receive the
other party. (Press to Talk)

Paging
A variety of paging modes allows paging over a wide area
from any master station. The paged party may respond
from the nearest master station.
Paging modes include external PA systems and/or Station
paging and Zone paging is for calling a limited area, and
All-call paging is for calling over the entire area.
A. External PA paging
1. Paging through external speakers is possible from any
master station, with the paged party able to respond
from the nearest master station.
2. External PA paging zones and all-call paging are
possible up to a maximum number of 7 zones (zone
1 through 7) or 15 zones (zone 1 through 15).
B. Station paging
1. Paging from any master station to all stations within
a certain area is possible through the station speakers.
A normal call can be placed during the page by any
master station in the area, but the page will not be
heard at stations in use in the area.
2. Station zone paging and all-call paging are possible
only within zone 1 through 7.
Note:
Zone paging and All-call paging

Other Paging Modes
1. Combination paging
Combination paging is used when several z ones must be
paged simultaneously through External PA or Station
paging. A special paging area can be created wherever
the paging ranges overlap by combining several zones. A
maximum of 10 combinations can be created in this w ay
from a maximum of 1 5 individual zones.
2. Emergency all-call paging
Emergency external PA or station all-call paging can be
made either from the specified station (No.247) or by
an external input signal connected to line No. 247. All
normal calls and pages are interrupted f or the duration
of the emergency All-call page, returning to normal
when the page is terminated.
3. Paging priority
In normal station paging, the page is not heard at any
station already in use. By using the paging priority
function, the call can be interrupted to allow the page
to go through. A holding tone sounds at the other
party's station, and the call is restored when the page
is terminated.

All-Call Paging and Individual Zone Paging
External PA paging to a specific zone is possible from any
master station by pressing
and the desired zone number ('0' = all-call). It is possible to
wait for a response in this mode, but anything said will be
broadcast over the entire zone. It is best to end the paging
call by pressing
and waiting for a response.
All-call paging of zones 1 through 7 can be done in both
the External PA paging mode, through An external amplifirs and speakers, and the station paging mode, through
the station speakers. All-call paging of zones 8 through 15
can be done only in the external paging mode.
To respond to a paging call, go to the nearest master station and press either
(All-call paging response).
Paging transfer
An external PA paging call can be made by a called party of
an existing call to a third party, the third party's response
accepted while the original call is on hold, and the original
call resumed when th e response call has ended. Press
(Zone paging response) or
All-call paging
Zone paging
Response to zon e
paging
and the desired zone number. This puts the original call on
hold and makes the External PA and or Station paging call.
Then, press
to restore the original cal l, and wait for the
response to the paging call. When the response is received,
press
and the original goes back on hold allowing the
second call to be taken. When the second call is completed,
press
and the original call can be resumed.
Note 1: When all-call paging is initiated during zone paging,
the Zone paging is interrupted and restored after
the all-call paging is finished.
Note 2: To respond to Zone paging by pressing
No.200 registration of the stations (consecutive
station numbers) within each zone must be made.
Such registration is required for both external and
station paging. For further details, please refer to

kept with the privacy switch
To broadcast emergency all-call paging, move the privacy
switch to
The highest priority all-call paging can be broadcast to all
zones without pre-announcement of paging. During emergency all-call paging, all other paging calls and normal calls
are interrupted until the emergency message is finished.
1. This function may be used to announce emergency
instructions from the specified station No.247 . It may
also be used to provide the signal tones such as chime
or alarm signals when the signal sources are fed to
No.247 circuit.

Interruption of call
When the station being paged is already on the line, the
call is interrupted. And the calling party is put on hold
while the paging message is delivered.
2. The calling party will be restored after the paging
message is finished and his original conversation may be
resumed.
3. If the person paged wishes to respond immediately, he
should dial

Camp-on-busy
Station paging to zone 1
Note 1: If the station called is in the process of dialing
when station paging is initiative, paging will not
be heard at that station and the call can be com-
pleted without interference.
Note 2: If a station being paged with station paging is
called by a third party, camp-on-busy will result.
Note 3: If any station in a given zone (zone 1, for example)
pages another zone (zone 2, for example), station
paging to stations in zone 1 results in camp-on-
busy.
Note 4: If station paging priority is used, the station num-
bers within the zone area must be programmed
at station No. 200. This registration is also required when station paging priority is unnecessary.
For further details, see Installation Hand Book for
EXES-5000 CPU-55.
Note 5: Use of both station paging priority and external
paging: Station paging priority interrupts calls in
stations of zones 1 through 7 for both station and
external paging. If station paging and external
paging are used simultaneously, allocate station
paging to zones 1 through 7 and external paging to
zones 8 through 1 5.
Note 6: Use of both priority station paging and external
paging within 7 zones: When responses are requir-
ed for pirority station paging but not for external
PA paging, No.200 registration of the station
allocation tables for the paging zones should be
done only for station paging. Calls are not interrupted during exte rnal paging, in this case.
