Multiple Call Forwarding - Don’t Answer - CCIS M-42
Service Conditions
1. The service conditions within the node comply with those of MULTIPLE CALL FORWARDING-
DON’T ANSWER [M-25].
2. A call can be forwarded by CALL FORWARDING a maximum of one time between nodes in a CCIS
network. 
3. When CALL FORWARDING is performed in a CCIS network, the following services are not available
at a forwarded-to station:
CALL FORWARDING-ALL CALLS-OUTSIDE [C-28]
CALL FORWARDING-BUSY LINE-OUTSIDE [C-60]

M-42 Multiple Call Forwarding - Don’t Answer - CCIS
Service Conditions (cont’d)
4. When a call is set to be forwarded to a calling party by CALL FORWARDING-DON’T ANSWER - CCIS
[M-42], the call forwarded to the calling party is ignored and the last station keeps ringing.
5. The type of forwarding to be displayed is CF NANS at the terminating node.
6. When a call is terminated to an ATTENDANT CONSOLE [A-3] by the MULTIPLE CALL
FORWARDING-DON’T ANSWER - CCIS [M-42], the call type is NANS.
7. There is no limit to the number of jumps for MULTIPLE CALL FORWARDING-NO ANSWER.
8. The system data (ASYD, SYS1, INDEX 486, bit 0-2) decides the maximum number of times for activating
a call forwarding service between nodes through CCIS. The number of times is selected in the range of 1
time to 7 times (ASYD, SYS1, INDEX 486, bit 0-2 = 0 means the enhanced feature is not available).
9. The number of times for activating this service between CCIS nodes is decided by system data
programmed at the node that has the station operating the first Call Forwarding service through CCIS link.
However, when the node accommodating the station operating the service first has not programmed, the
number of times is decided at the node that accommodates the destination of the first Call Forwarding -
CCIS service.

Service Conditions (cont’d)
10. When the destination is the calling party:
a.) CALL FORWARDING - DON’T ANSWER: the call continues to place at the station that
forwards the call to the caller.
In this case, the calling party hears ringback tone:
11. When Call Forwarding is restricted because the number of times data or service restriction data, the call
continues to ring at the station that has restricted the service.
Example 1: Multiple Call Forwarding - CCIS is restricted because the service has already been activated
the preassigned maximum number of times. A maximum of three times is available for Call Forwarding
through CCIS.

Service Conditions (cont’d)
Example 2: Multiple Call Forwarding - CCIS service is restricted because the service is not effective at
the node.
12. Even if Call Forwarding is set from the forwarded station to the forwarding station, the Call Forwarding
service is effective, as shown in the example below:
When Office A selects the number of times for Call Forwarding for 5 times, five times of Call Forwarding
are executed as Call Forwarding 1 to Call Forwarding 2 to Call Forwarding 3 to Call Forwarding 2 to Call
Forwarding 3.
13. The following services set to the forwarded destination are not available with Multiple Call Forwarding -
CCIS services, except when the services below are activated through CCIS link:
CALL FORWARDING - ALL CALLS - OUTSIDE [C-28]
CALL FORWARDING - BUSY LINE - OUTSIDE [C-60]
CALL FORWARDING - DON’T ANSWER - OUTSIDE [C-74]
14. The following services are activated within one node. The maximum number of times for activating this
feature is the same as previous software releases:
MULTIPLE CALL FORWARDING - ALL CALLS [M-44]: 5 times
MULTIPLE CALL FORWARDING - BUSY LINE [M-24]: 5 times
MULTIPLE CALL FORWARDING - DON’T ANSWER [M-25]: unlimited

15. The following are detailed examples of Call Forwarding - CCIS activation. These examples are activated
under the conditions below:
 The maximum number of times to activate the service is three (programmed in Office A and
Office B).
 The last call forwarding is operated by Call Forwarding - All Calls/Don’t Answer service.
 Any kind of D
term, ISDN terminal, PHS, etc. is available to be used for the calling/intermediate
party.
 Any kind of Call Forwarding service (All Calls/Busy Line/Don’t Answer) is available to be set
at the calling/intermediate terminal.
a.) The service is restricted because the terminating Office B is unavailable for enhanced Call

b.) The service is restricted because the service has already been activated the predetermined number
of times.
c.) When Office A is not available for the enhanced Call Forwarding feature, the number of times the

Service Conditions (cont’d)
d.) The Call Forwarding service is activated four times, because the call is forwarded from Office D
to Office E through FCCS link:
Note:
Call Forwarding service activated through FCCS link (C.F.*) is not included in the number of times that the Multiple
Call Forwarding - CCIS service is activated.
e.) When the trunk/station incoming call terminates through FCCS link, the number of times for the
service activation may vary, depending on the kind of Call Forwarding service (All Calls/Busy
Line/Don’t Answer) set to the station in the terminated node. This condition is also applied when
the call is forwarded from Office A to Office B through FCCS link.
