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.
