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.

M-40 Multiple Call Forwarding - All Calls - CCIS
Service Conditions (cont’d)
The Calling party hears busy 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 not identical.
10. When Call Forwarding is restricted because the number of times data or the service restriction data, the
call is terminated to the station that is restricted Multiple Call Forwarding - CCIS 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.

Multiple Call Forwarding - All Calls - CCIS M-40
Service Conditions (cont’d)
Example 2: Multiple Call Forwarding - CCIS service is restricted because the service is not effective at
the node.
11. 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.
12. 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]
13. The following services are activated within one node, therefore, the number of times for these services are
independent. 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
When the call is forwarded 
by C.F. - A/D - CCIS, the call 
terminates to this station. 1st C.F.

M-41  Multiple Call Forwarding - Busy Line - CCIS
General Description
This service feature permits a call to a busy station to be forwarded in a CCIS network, multiple times, to a
predesignated idle station.
1. With existing CALL FORWARDING-BUSY LINE [C-2] (CF-B) service:
2. With MULTIPLE CALL FORWARDING-BUSY LINE [M-24] service:

Station C. Station C sets Call Forwarding-Busy Line to Station D.
2. Stations A, B, and C are busy when an incoming call is directed to Station A. The call is forwarded to
Station B first, then to Station C, and on to Station D. The calling party receives ringback tone, and ringing
starts at Station D.
3. Station D lifts the handset to answer and is connected to the calling party.
Service Conditions
1. The service conditions within the node comply with those of MULTIPLE CALL FORWARDING-BUSY
LINE [M-24]. 
2. A call can be forwarded by CALL FORWARDING a maximum of one time between nodes in a CCIS
network.
