C-46 Call Forwarding - Busy Line - CCIS
Service Conditions (cont’d)
d.) A Central Office call is directed to Station B. Station B is call forwarded to Station C. Station C is
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 IPX 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.
