Dial Intercom D-87
Operating Procedure (cont’d)
PRIME LINE PICK UP-Dterm [P-13D]:
The Dterm may be programmed to seize the incoming call on the AUTOMATIC, MANUAL, or DIAL INTERCOM
lines before the Prime Line. If two incoming calls terminate simultaneously to both the Prime Line and the DIAL
INTERCOM line, when the user goes off-hook, PRIME LINE PICKUP-D
term [P-13D] will seize the DIAL
INTERCOM line before the Prime Line. If only the Prime Line is ringing when the user goes off-hook, then PRIME
LINE PICKUP D
term [P-13D] will seize the Prime Line. The programmable options and ringing priority are
illustrated in the following table:
Service Conditions 
1. Only Dterms can be assigned as a member of a DIAL INTERCOM group. 
2. All members of the same DIAL INTERCOM group must be assigned in the same Module Group.
3. Up to 32 stations may be assigned to one DIAL INTERCOM group. Each station in the DIAL
INTERCOM group can be assigned as an Automatic, a Manual and a DIAL INTERCOM member of three
different groups. 
4. No more than one connection can be established at the same time in one DIAL INTERCOM group. 
5. A three-party conference can be established in a DIAL INTERCOM group if Intercom Bridge service is
available. If a fourth party tries to activate Intercom Bridge service, the connection is denied.
6. The maximum number of DIAL INTERCOM groups in the PBX is 50 per Module Group. 
7. It is possible to simultaneously assign one group of stations as an Automatic/Manual Intercom group, as
well as a DIAL INTERCOM group. 
8. The distinctive ringing (three-burst ringing) sent from an incoming DIAL INTERCOM station takes
priority over the ringing of multi-line appearances.
9. Features normally available to multi-line appearances are not available to DIAL INTERCOM lines. 
10. DIAL INTERCOM lines cannot be held by pressing the HOLD key. 
11. When a station is moved from one DIAL INTERCOM group to another via system commands, the DICM
key on the associated D
term must be deleted before the change is made. 
12. Port traffic and station PEG COUNTS [P-7] reports will record the use of the DIAL INTERCOM feature
under “other.”
13. Dedicated D
term feature keys cannot be used during a DIAL INTERCOM call. Only the SPEAKER key
for hands-free operation can be used. 
14. If there are simultaneous incoming calls to the Prime Line, Automatic Intercom Line, the Manual Intercom
Line, and/or the DIAL INTERCOM line, the Prime Line will normally be selected when the station goes
off-hook. The selection order can be changed for each D
term via office data assignment.

D-90D Delayed Ringing - Dterm
D-90D Delayed Ringing - Dterm
General Description
This feature allows a Dterm to receive an incoming ringing signal after a predetermined time.
1. In Boss/Secretary service, a call terminating on the bosss line first rings at the secretarys station. If the
secretary does not answer within a preprogrammed time, the boss station will also ring. This service is
convenient when many lines terminate on a secretarys phone, and the secretary is engaged in a call, or is
temporarily away from the phone, and cannot answer the call terminated to the bosss station.
2. Calls terminated to the bosss station may be routed to multiple secretaries by assigning timing delays for
ringing to each secretarys station.
3. When a call to the boss station is received, it rings on Secretary As station. If it is not answered in a
preprogrammed time, it will also ring on Secretary Bs station. If Secretary B does not answer within the
second preprogrammed time, the call will also ring on Bosss station.

D-90D Delayed Ringing - Dterm
General Description (cont’d)
6. DELAYED RINGING may also be used for calls terminated to single-line telephone appearances on a
Dterm. Calls to single line appearances that are not answered within a preprogrammed time will ring on the
next station in sequence.
7. A call rings on Single Line Station A. If Station A does not answer within a preprogrammed time, the call
also rings on D
term Station B. If the call is not answered within the second preprogrammed time, the call
also rings on Dterm Station C.
Operating Procedure
No manual operation of the feature is required after it has been programmed in system data.
Service Conditions
1. This feature is available for multi-lines on Dterms.
2. Delay timing for each line on the D
term may be programmed through the MAT.
3. Delay timing may be 10, 20, or 30 seconds.
Interactions
1. Off-hook ringing on a Dterm will follow the assigned DELAYED RINGING-Dterm [D-90D] timer the
same as on-hook ringing.
2. Stations that have multi-line appearances with DELAYED RINGING-D
term assigned must be aware of
the interaction with CALL FORWARDING-DON’T ANSWER [C-2]. Example: Station A appears on
D
term B with a delayed ringing of 30 seconds (RG = 4); and also on  Dterm C with a delayed ringing time
of 20 seconds (RG = 5). If Station A sets CALL FORWARDING-DON’T ANSWER [C-2] and the CALL
FORWARDING-DON’T ANSWER [C-2] timer is set at 24 seconds, when an incoming call comes into
Station A, it will begin to ring; at 20 seconds D
term C will begin to ring also; at 24 seconds the call will
forward to Station A’s target destination and Station A and Dterm C will stop ringing. Dterm B never rings.
3. After a call has been answered by a secretary, the activation of the boss/secretary feature by the secretary
to a single-line boss station will not reactivate the DELAYED RINGING-D
term cycle.

Delay Announcement - Attendant D-114
D-114 Delay Announcement - Attendant
General Description
This feature provides a recorded announcement to the incoming trunk caller waiting to be answered by the
Attendant. This feature is divided into the following two types, depending on the time when the call is connected
with the announcement trunk.
1. The call is connected to announcement trunk immediately after terminating to the Attendant Console. The
announcement continues until the Attendant answers, or the trunk side abandons the call.
2. The call is connected to the announcement trunk after the ringback tone connection.
Operating Procedure
When the announcement service is provided immediately after the call terminates:
1. When an incoming call terminates to an Attendant Console, which is handling calls, the calling party
receives an announcement from the Digital Announcement Trunk (DAT).
2. When the Attendant completes call handling, ringing starts at the Attendant Console.
3. The Attendant presses the ANSWER key. The calling party and the Attendant talk with each other.
When the announcement service is provided after a fixed time:
1. When an incoming call terminates to an Attendant Console, the LDN key lamp starts to flash and ringing
starts at the Attendant Console, and the calling party receives the ringback tone.
2. When the Attendant has not answered for the designated time (SYS1, INDEX 242), the call is connected
to the announcement trunk automatically (the lamp keeps flashing and the ringing continues at the
Attendant Console).
3. If the Attendant does not answer the call when the first announcement completes, the trunk call
disconnects from the announcement automatically and the caller hears the music on hold.
4. The Attendant presses the ANSWER or LDN key. The calling party and the Attendant talk with each
other.
Service Conditions
When the Delay Announcement service is provided immediately after the call terminates:
1. This service requires a PA-4DATA/4DATB (DAT) circuit card or an external announcement machine.
2. This feature is available for the following incoming trunk types: 
a.) Ring down
b.) LDN (DID, TIE)
c.) Call Forwarding - All Calls/Busy Line/Dont Answer (DID, TIE)
d.) Call Forwarding - Intercept - Attendant (DID, TIE)
e.) CO line, TIE Line incoming call via CCIS network.
Note:The incoming call transferred to the Direct-in Termination trunk by Call Forwarding - Busy Line/Don’t Answer
service is not available.
3. This feature is not available for TAS incoming calls.
4. When the system is in NIGHT mode, this service is not available.
5. At the time of DAY/NIGHT mode changeover, the call connected to the announcement will be released,
and the calling party receives reorder tone. A call will be released as follows, according to the incoming
trunk type: 
a.) When a call terminates from a trunk where trunk release cannot be supervised, the trunk will be
released forcefully. (Night Transfer station cannot be assigned.)

D-114 Delay Announcement - Attendant
Service Conditions (cont’d)
b.) When a call terminates from a trunk where trunk release can be supervised, the trunk will not be
released forcefully, but will be released on its own accord. (Night Transfer station can be
assigned.)
6. This service is not available for incoming calls to an individual Attendant.
7. When a CO line incoming call terminates to a trunk where call clear cannot be confirmed after the call has
been answered, the incoming trunk and announcement trunk remain connected until Attendant answers
and releases the trunk.
8. When a call terminates to an incoming trunk, for which this service is not required, the connection route
between the incoming trunk and the announcement trunk is restricted.
9. The announcement trunk remains connected until the incoming trunk is released. (Timer Control Release
is not used.)
10. In case of multiple connection:
a.) Caller is not connected at the beginning of the announcement.
b.) The announcement trunk is not released by Attendant upon answering or releasing the incoming
trunk.
11. For single connections, this service is not available when the announcement trunks are all busy.
12. When an external announcement machine is used, the announcement starts from the time the PBX
acknowledges the announcement trunk answer, and ends at the time of the announcement trunk release.
13. Whether to use an announcement trunk for single or multiple connection is determined by the System Data
on a tenant basis.
When the announcement is provided after the ringback tone has been heard:
1. This service requires a PA-4DATA/4DATB (DAT) circuit card or an external announcement machine.
2. When the caller is hearing the message or music, the call is still indicated on the ICI key on the Attendant
Console. Therefore, the Attendant can answer the call anytime by pressing the ANSWER key or the
corresponding ICI key.
3. The message is sent in the following sequence. Whether to send the second message and after can be
determined in the system data. When the other message(s) is not sent after the first announcement, MUSIC
ON HOLD [M-7] continues.
Note:Separate timers are used for No Answer Timer and Music On Hold.
4. Each channel of the DAT can record a single message. Recording time for a single message is 16 or 32
seconds.
5. When Multiple Playback is selected, additional DAT channel is required for the second announcement,
even if the second announcement has the same contents as the first one.
6. A maximum of 10 incoming trunk calls can be connected to a single DAT trunk at one time for sending a
prerecorded message from the beginning to the called parties.
