Service Conditions (cont’d)
30. SPLIT CALL FORWARDING [S-99] is available only when the calling party is the station or the CCIS
line.
31. When a call terminates to a busy station setting CALL FORWARDING-BUSY LINE - CCIS, depending
on the calling station service restriction class, it can be selected to make the station busy (not to activate
Calling Forwarding-Busy Line) and to activate services as ATTENDANT CAMP-ON [A-1], BUSY
VERIFICATION [B-3], CALL WAITING - TERMINATING [C-12], STEP CALL [S-13], etc.
32. This service is not available when the called party is the attendant console, monitoring station, or the
paging station. However, the service is available when these stations are designated as the transfer
destination of Call Forwarding - Busy Line service.
33. This service is available only when the called party is busy and has set Call Forwarding - Busy Line. In
case Call Forwarding - Busy Line is set as the second jump or later in the Multiple Call Forwarding link,
this service is not available.
34. This service is available in the following occasions:
a.) when the destination of the Call Forwarding - Busy Line service is the calling station,
b.) when the calling party is the attendant console or the night station, and the destination Call
Forwarding - Busy Line service is also the attendant console or the night station.
Interactions
1. If access codes for CALL FORWARDING-BUSY LINE - CCIS and CALL FORWARDING-DON’T
ANSWER - CCIS [C-47] are the same, only one key needs to be assigned in AKYD.
2. When CALL WAITING [C-12, 31], ATTENDANT CAMP-ON WITH TONE INDICATION [A-45], or
CALL BACK [C-44] is directed toward Station A with call forwarding set to Station B, Station B will
receive Call Waiting Tone.
3. A non-controlling UCD station is allowed to activate CALL FORWARDING-BUSY LINE - CCIS. When
this station sets CALL FORWARDING-BUSY LINE - CCIS, only calls dialed directly to this station are
call forwarded. 
4. If an Attendant attempts BUSY VERIFICATION [B-9] to station A that has CALL FORWARDING-
BUSY LINE - CCIS set to Station B and Station B is busy, BUSY VERIFICATION proceeds again with
Station A. If Station A has set call forwarding to the Attendant Console, BUSY VERIFICATION [B-9] is
allowed at Station A.
5. When CALL FORWARDING - BUSY LINE - CCIS is in effect, the activating station may be used to
originate calls.
6. When a call is forwarded, the destination station is recorded for STATION MESSAGE DETAIL

Call Forwarding - Don’t Answer - CCIS C-47
Service Conditions (cont’d)
10. If a station transfers a call to another station that has set CALL FORWARDING-DON’T ANSWER -
CCIS and releases from the call, recall service will override CALL FORWARDING-DON’T ANSWER
- CCIS if the call is unanswered after a predetermined time period (unless Blind Transfer station is in
service).
11. When calls are forwarded to the Attendant Console, the INCOMING CALL IDENTIFICATION [I-2]
feature allows the Attendant to identify the call as a forwarded call. 
12. When a station-to-station call within the same node is CALL FORWARDING-DON’T ANSWER [C-3]
to the Attendant Console, the call terminates on the NANS key. When the call is CALL FORWARDING-
DON’T ANSWER - CCIS to the Attendant Console, it terminates on the NANS key. 
13. When the system is in Night mode, CALL FORWARDING-DON’T ANSWER - CCIS to the Attendant
Console will continue ringing at the called station, or transfer to the ATTENDANT NIGHT TRANSFER
[A-19] station, if provided. 
14. When an Attendant extends a call to a station in another node in the CCIS network, and that station has
set CALL FORWARDING-DON’T ANSWER - CCIS, the call will be forwarded if the called station does
not answer within a predetermined time period.
15. If separate access codes are programmed into system data for CALL FORWARDING-DON’T ANSWER
- CCIS and CALL FORWARDING-BUSY LINE - CCIS [C-46], separate feature keys must be
programmed on each D
term to equip it for both features.
16. When OUTGOING TRUNK QUEUING - CCIS [O-12] is provided, a station can use this feature and one
of the other call forwarding features at the same time. When a trunk becomes available, ringback tone will
be to the forwarding, not the forwarded-to, station.
17. If any of the following restrictions are in effect at a forwarded-to station, incoming trunk calls to the
forwarding station will not be forwarded (intercept arrangements will apply):
a.) Fully Restricted Station
b.) Station Restricted from Outgoing Calls
c.) Toll Restricted Station 
18. If a member of a UNIFORM CALL DISTRIBUTION (UCD) [U-1] group sets CALL FORWARDING-
DON’T ANSWER - CCIS, only UCD calls to that extension number are forwarded.
19. When a call is forwarded, the number recorded in the STATION MESSAGE DETAIL RECORDING [S-
10] is the forwarded-to telephone number.

cancelled via the dial pad.
21. When an Attendant extends a call to a station in the same node which has set CALL FORWARDING-
DON’T ANSWER - CCIS, the called station will ring for 30 seconds. If the call is not answered, it will
forward across CCIS.
Interactions 
1. If access codes for CALL FORWARDING-BUSY LINE - CCIS and CALL FORWARDING-DON’T
ANSWER - CCIS are the same, only one key needs to be assigned in AKYD. 
2. ACFO is applicable to DID, DIT, and TIE Line calls only.
3. A non-controlling UCD station is allowed to activate CALL FORWARDING-DON’T ANSWER - CCIS.
When this station sets call forwarding, calls directed to this station will be forwarded. The member station
is not removed from the UCD group under the conditions of the call forwarding feature used. When it is
the station’s turn to ring, that call is affected by CALL FORWARDING-DON’T ANSWER - CCIS.

5. If the CALL FORWARDING-DON’T ANSWER - CCIS target station is a D
term which has activated DO
NOT DISTURB [D-21D], call forwarding is not activated. The forwarding station will ring beyond the

Call Forwarding - Intercept - CCIS C-48
C-48  Call Forwarding - Intercept - CCIS
General Description
This feature allows calls to an inoperative number, through a CCIS trunk, to be intercepted and routed to a recorded
announcement. This announcement will inform the caller that an inoperative number was dialed and will give the
Listed Directory Number for information. 
Operating Procedure
This feature is set in system programming and no manual operation is required.
Service Conditions 
1. This feature requires an announcement trunk and an announcement machine at each node. 
2. Only one call at a time can be connected to each announcement trunk. If a second call arrives while the
first call is being processed, the caller will receive ringback tone until the trunk becomes idle. This is when
AAED - M = 1.
3. If disconnect timing is programmed in System Data and the calling party forgets to hang up, the system
will automatically disconnect from the call after 30 seconds. If no disconnect timing is programmed, the
calling party will control disconnect.
4. This feature is provided on a per-tenant basis. 
5. Calls to restricted numbers will receive reorder tone.
6. Only one common message can be provided for all intercept conditions. 
7. The following call conditions are routed to CALL FORWARDING-INTERCEPT - CCIS:
 Vacant level
 Unassigned telephone number 
Interactions 
1. The trunk number will only be required when a multiple connection is assigned.
2. The COT trunk circuit is used to interface a customer-provided announcement machine. 
3. The Digital Announcement Trunk (DAT) card may be used for announcements instead of an external
announcement machine. In this case, the COT card is not required.
4. The type of connection to the announcement machine depends on whether the machine provides a battery
reversal at the end of the message. Battery reversal allows for the recycling of the message so that a calling
station will always be connected to the beginning of the message. Therefore, the calling party will continue
to hear ringback tone until connected to the beginning of the announcement.
5. See ANNOUNCEMENT SERVICE [A-15].
