Multiple Call Forwarding - All Calls - CCIS M-40
Service Conditions (cont’d)
5. SERVICE DISPLAY - CCIS [S-53] is available at the terminating node. The type of forwarding to be
displayed is CF ALL.
6. When a call is terminated to an ATTENDANT CONSOLE [A-3] by MULTIPLE CALL FORWARDING-
ALL CALLS - CCIS [M-40], the call type is ATND.
7. 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).
8. 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 that accommodates the station operating the service first has not been
programmed, the number of times is decided at the node that accommodates the destination of the first
Call Forwarding - CCIS service.
9. When Multiple Call Forwarding - CCIS is activated and the last intermediate party forwards (returns) the
call to the first calling party, the calling party may hear either ringback tone or busy tone.
The Calling party hears ringback tone when the forwarding destination number, assigned to the last
intermediate party (intermediate party 2 in the example below), and the calling party number sent from the
calling party are identical.
