Call Forwarding - All Calls - CCIS C-45
Service Conditions (cont’d)
14. CALL FORWARDING-ALL CALLS - CCIS can be overridden, allowing the forwarded-to station to
initiate or transfer calls to the forwarding station. 
a.) The idle forwarding station can be reached by the forwarded-to station, using CALL
FORWARDING OVERRIDE - CCIS [C-49].
b.) A busy forwarding station receives call waiting treatment when the designated station calls
directly or when EXECUTIVE RIGHT-OF-WAY - CCIS [E-8] is used.
c.) When CALL FORWARDING-ALL CALLS - CCIS is set to the Attendant Console, the
Attendant cannot reach the forwarding station using the override capability
15. When EXECUTIVE RIGHT-OF-WAY [E-1] [E-8] is initiated to a station, which has set CALL
FORWARDING-ALL CALLS - CCIS, EXECUTIVE RIGHT-OF-WAY - CCIS [E-8] terminates at the
forwarded-to station. 
16. If a called station has set call forwarding, and the forwarded-to station is listening to a tone being rung, or
has set CALL WAITING [C-12], CALL BACK [C-44], OUTGOING TRUNK QUEUING [O-2] [O-12],
or THREE-WAY CALLING [T-2], the calling station cannot use EXECUTIVE RIGHT-OF-WAY - CCIS
[E-8] to access the forwarded-to station. If attempted, the calling station will receive reorder tone.
17. When OUTGOING TRUNK QUEUING - CCIS [O-12] is provided, the forwarding station can use one
of the call forwarding features and OUTGOING TRUNK QUEUING - CCIS [O-12] at the same time.
Ringback tone is sent to the forwarding station and not to the forwarded-to station.
18. A call forwarded to a busy station that is allowed CALL WAITING [C-12] waits at the forwarded-to
station, provided that the forwarded-to station is in a two-way conversation and no other call is waiting. 
19. When a station that is call forwarded uses the CALL BACK - CCIS [C-44] feature, the automatic call back
rings to the forwarding, not the forwarded-to, station. 
20. If any of the following restrictions are in effect at a forwarded-to station, incoming trunk calls to the
forwarding station will not be call forwarded (intercept arrangements will apply): 
a.) Fully Restricted Station
b.) Station Restricted from Outgoing Calls
c.) Toll Restricted Station
21. When a station in a Hunt Group sets CALL FORWARDING-ALL CALLS - CCIS, it is temporarily
removed from the Hunt Group. 
22. When the Pilot station of a UNIFORM CALL DISTRIBUTION (UCD) [U-1] group sets CALL
FORWARDING-ALL CALLS - CCIS, only calls to the Pilot number are forwarded. 
23. If the forwarding station is the Pilot station of a UCD group and the forwarded-to station is idle, a call to
the UCD group is routed immediately to the forwarded-to station. If the forwarded-to station is busy, the
calling station will receive busy tone.
24. If a station in a UCD group sets CALL FORWARDING-ALL CALLS - CCIS, it is temporarily removed
from the group. 
25. When a call is forwarded, the telephone number recorded in the STATION MESSAGE DETAIL
RECORDING [S-10] is the forwarded-to station.
Interactions
1. Users are unaccustomed to hearing ringback tone when responding to their own station’s ring. Be sure to
inform them when providing ringback tone with CALL FORWARDING-ALL CALLS - CCIS in System
Data 1, Index 69, Bit 1. 
2. Call forwarding can only be activated from an idle station.

Interactions (cont’d)
3. When CALL WAITING [C-12, 31], ATTENDANT CAMP-ON WITH TONE INDICATION [A-45], and
CALL BACK [C-44] is directed toward Station A with call forwarding set to Station B, Station B will
receive Call Waiting Tone.
4. When a station in a Hunt Group initiates CALL FORWARDING-ALL CALLS - CCIS, calls normally
destined for this station will not be received. The Hunt Group operates as if the station were busy.
5. A non-controlling UCD station is allowed to activate call forwarding. With this station call forwarded,
only directly-dialed calls to this station are call forwarded. The member station is removed from the UCD
group under the conditions of this call forwarding feature. 
6. When CALL FORWARDING-ALL CALLS - CCIS is in effect, the activating station may be used to
originate calls. See System Data 2, Index 6, Bit 4. 
7. When a station is call forwarded, the destination station is recorded STATION MESSAGE DETAIL
RECORDING [S-10].
8. CALL FORWARDING-ALL CALLS - CCIS can be overridden allowing Station B to initiate or transfer
calls back to Station A.
Programming
STEP 1:ASYD - System Data 1, Index 4, Bit 6. One burst of ringing at forwarding station when CALL
FORWARDING-ALL CALLS - CCIS is in service? 0/1: No/Yes.
System Data 1, Index 69, Bit 1. A burst of ringback tone to alert the person receiving a call that this is
a CALL FORWARDING-ALL CALLS - CCIS call. In service? 0/1: No/Yes. Normally assigned as
data “0”. 
System Data 2, Index 6, Bit 4. Enable stations set for CALL FORWARDING-ALL CALLS - CCIS be
allowed to use their phones normally. If data “0” is assigned, the station will only be able to call the
Attendant Console. Assign on a per-tenant basis. 
STEP 2:ANPD - Reserve a number level for feature access and cancel. Assign for Normal (N), Hooking (H),
and Busy (B). Assign NND in accordance with a predetermined numbering plan.
STEP 3:ASPA - Assign an access code to CALL FORWARDING-ALL CALLS - CCIS entry, SID = 8 and to
CALL FORWARDING-ALL CALLS cancel SID = 9. Assign Connection Status Index (CI) for
Normal (N) service.
STEP 4:ASFC - Assign a Service Feature Class that allows SFI = 7 to the stations that activate CALL
FORWARDING-ALL CALLS - CCIS.
STEP 5:AKYD - For D
term sets, CALL FORWARDING-ALL CALLS - CCIS may be assigned to a
programmable line/feature key. Assign Type:Function:CALL FORWARDING-ALL CALLS [2]. 
STEP 6:ADSL - Assign FDA key; Assign SN=1 (Originating; DT Connection) and FKY=2 (Call Forwarding -
All Calls).
This command is used for assigning a function to each soft key.
STEP 7:AT N R - Allow tenant-to-tenant connection for Inter and Intra-tenant connections. Assign Tenant
Restriction Index (TRI) = 1. For this feature to be set by the Attendant Console, assign Inter and Intra-
Tenant connection via the Attendant Console. TRI = 3.
STEP 8:ACFS - CALL FORWARDING can also be assigned in this command.

call forwarded - CCIS to Station D. Call forwarding does not occur to Station D. If Station C is
idle, Station C will ring. If Station C is busy, busy tone is returned from Station C.
2. Registration memories for CALL FORWARDING-BUSY LINE and CALL FORWARDING-DON’T
ANSWER [C-3] are common. Changing System Data will enable separation of the two, permitting
separate access codes to be assigned. 
3. CALL FORWARDING-BUSY LINE can be provided on a system and/or an individual basis.
4. CALL FORWARDING on a system basis allows any incoming calls which encounter a BUSY condition
to be forwarded to a predetermined station or ATTENDANT CONSOLE [A-3].
5. Individual CALL FORWARDING-BUSY LINE supersedes system CALL FORWARDING.
6. If all the stations in the terminating hunt group are busy, the forwarding call will hear busy tone and will
not return to the calling party’s Hunt group.
7. When MULTIPLE CALL FORWARDING-BUSY LINE [M-24] service is activated, hunting will be
performed at the last destination of the forwarded call, even though the multiple jumped stations are in a
hunt group. 
8. When the pilot station of a Pilot Hunt Group activates CALL FORWARDING - BUSY LINE to a station
(not a member of a hunt group) and system parameters specify that call hunting will be activated at the
forwarded station, the NEAX2400 IMX will send busy tone if the forwarded station is busy. If the system
parameters specify hunting at the forwarding station, and the forwarded station is busy, the call will hunt
in the forwarding station’s hunt group.
9. When a station activates CALL FORWARDING-ALL CALLS [C-5] to a pilot in a hunt group, and the
pilot activates CALL FORWARDING-BUSY LINE to another pilot hunt group, if system parameters
define the call to hunt to the forwarded hunt group and the pilot station is busy, the calling party will hunt
at the called station’s hunt group. If system parameters define the call to hunt to the forwarding hunt group
and the pilot station is busy, the calling party will then hunt to the forwarding station’s hunt group.
10. If the called station is the pilot of a UCD group and activates CALL FORWARDING-BUSY LINE the
calling station will queue to the UCD group and will not Call Forward. 
11. CALL FORWARDING-BUSY LINE - CCIS is assigned to a station via CLASS OF SERVICE-
INDIVIDUAL [C-15] programming.
12. There is no limit to the number of stations that can simultaneously set CALL FORWARDING-BUSY
LINE - CCIS.

C-46 Call Forwarding - Busy Line - CCIS
Service Conditions (cont’d)
13. CALL FORWARDING-BUSY LINE - CCIS can be set by any number of stations to the same forwarded-
to station.
14. The display of the forwarded-to telephone number on the LCD panel of the forwarding D
term can be
allowed or denied in system programming on a system-wide basis. 
15. When calls are forwarded to the Attendant Console, INCOMING CALL IDENTIFICATION [I-2] allows
the Attendant to identify the call as a forwarded call. 
16. When a call is call forwarded to the Attendant Console, the Attendant can identify the called station at the
Attendant Console. 
17. When a station sets CALL FORWARDING-BUSY LINE - CCIS to the Attendant Console, and the
system is in the Night mode, the calling party will receive reorder tone, or transfer to the ATTENDANT
NIGHT TRANSFER [A-19] station, if provided.
18. When ATTENDANT CAMP-ON WITH TONE INDICATION [A-45] is directed to a station which has
set CALL FORWARDING-BUSY LINE - CCIS, and the forwarded-to station is busy, the call is camped-
on to the called station.
19. If ATTENDANT CAMP-ON WITH TONE INDICATION [A-45] is directed to a station which is
forwarded to a busy station in a Hunt group, the call hunts for an idle station. If all stations in the Hunt
group are busy, the call is camped-on to the forwarded-to station.
20. If a calling station, Attendant Console, or trunk receives busy tone after dialing a station which has set
CALL FORWARDING-BUSY LINE - CCIS because both the called and forwarded-to stations are busy,
and if the calling station activates BUSY VERIFICATION - CCIS [B-9], CALL BACK - CCIS [C-44],
CALL WAITING-TERMINATING [C-12], or EXECUTIVE RIGHT-OF-WAY - CCIS [E-8], these
services will be activated to the forwarded-to station. 
21. If any of the following restrictions are in effect at a forwarded-to station, incoming trunk calls to the
forwarding station will not be call forwarded (intercept arrangements will apply): 
a.) Fully Restricted Station
b.) Station Restricted from Outgoing Calls
c.) Toll Restricted Station 
22. CALL FORWARDING-BUSY LINE - CCIS supersedes the station Hunting features [S-7, S-8, S-9].
23. If a forwarded-to station is a member of a UCD group and that station is busy, the call will ring at an idle
station within the group. If all members of the group are busy, the call remains in queue waiting for a
member to become available; or (if programmed), until DELAY ANNOUNCEMENT-UCD [D-31] or
OVERFLOW-UCD [O-13] is invoked.
24. If a member of a UCD group, other than the Pilot station, sets CALL FORWARDING-BUSY LINE -
CCIS, only calls to that extension number are forwarded.
25. When a call is forwarded, the number recorded in the STATION MESSAGE DETAIL RECORDING [S-
10] is the forwarded-to telephone number. 
26. CALL FORWARDING-BUSY LINE - CCIS data remains programmed even if the system is reinitialized
without data memory clear or should a power failure occur.
27. CALL FORWARDING-BUSY LINE - CCIS can also be accessed from a D
term via the dial pad or SPEED
CALLING-ONE TOUCH [S-26D]. If this feature is accessed via the dial pad, it must also be cancelled
via the dial pad. 
28. If separate access codes are programmed into System Data for CALL FORWARDING-BUSY LINE -
CCIS and CALL FORWARDING-DON’T ANSWER - CCIS [C-47], separate feature keys must be
programmed on each D
term to equip it for both features.
29. If the station is in a Hunt Group, the call will hunt.
