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 to Station D. Call forwarding does not occur to Station D. If Station C is idle,
Station C will ring beyond the Don’t Answer timer.
2. CALL FORWARDING-DON’T ANSWER can be provided on either a system or an individual basis.
3. Individual CALL FORWARDING-DON’T ANSWER supersedes system CALL FORWARDING.
4. CALL FORWARDING on a system basis allows direct incoming trunk calls that encounter a DON’T
ANSWER condition to be forwarded to a predetermined station or the ATTENDANT CONSOLE [A-3].
5. The operator answering a CALL FORWARDING call can identify the called telephone number on the
ATTENDANT CONSOLE [A-3] display.
6. CALL FORWARDING-DON’T ANSWER - CCIS is assigned to a station via CLASS OF SERVICE-
INDIVIDUAL [C-15] programming.
7. There is no limit to the number of stations that can simultaneously set CALL FORWARDING-DON’T
ANSWER - CCIS.

forwarded-to station.
9. 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.
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.
