2. Dial the specific CALL FORWARDING - ALL CALLS cancel code; receive special dial tone. 
3. Dial the TENANT [T-12] number (2 or 3 digits). 
4. Dial the originating telephone number; receive service set tone.
Service Conditions
1. If CALL FORWARDING - ALL CALLS [C-5] is set at the called station, the call is forwarded to a
designated station that has set CALL FORWARDING-ALL CALLS [C-5] or CALL FORWARDING-
BUSY LINE [C-2].
2. A call can be forwarded up to five times, maximum, by MULTIPLE CALL FORWARDING - ALL
CALLS [C-5], and only by the voice port of a D
term, or by a single line telephone. 
3. A call will not forward any farther than the station to where it has been forwarded to.
4. If a forward destination is busy, and if neither CALL FORWARDING - BUSY LINE [C-2] nor CALL
FORWARDING - ALL CALLS [C-5] is set, the caller hears a busy tone.
5. If the originating station is designated as the forward destination, the call will not be forwarded.
6. CALL FORWARDING - BUSY LINE [C-2] and CALL FORWARDING - ALL CALLS [C-5]
combination:
a.) A maximum of five forwarding operations can be performed by any combination of CALL
FORWARDING-ALL CALLS [C-5] AND CALL FORWARDING-BUSY LINE [C-2].
b.) If the fifth forward destination is busy, the call will forward if CALL FORWARDING - DONT

M-44 Multiple Call Forwarding - All Calls
Service Conditions (cont’d)
c.) If a sequence of CALL FORWARDING - ALL CALLS [C-5] and CALL FORWARDING -
BUSY LINE [C-2] forwards the call back to the originating station, the forward is not made and
the caller hears a busy tone.
d.) If a sequence of CALL FORWARDING - ALL CALLS [C-5] and CALL FORWARDING -
BUSY LINE [C-2] forwards the call back to the originally called station, and if that station
forwards the call with CALL FORWARDING - BUSY LINE [C-2], the ultimate destination will
be the originally called station. If, however, the originally called station forwards the call with
CALL FORWARDING - ALL CALLS [C-5], the ultimate destination will be the station it has
designated as its CALL FORWARDING - ALL CALLS [C-5] destination.
e.) If the call is forwarded back to the station where it has been forwarded to, the CALL FORWARD
will terminate at that station.
7. CALL FORWARDING - ALL CALLS [C-5], CALL FORWARDING - BUSY LINE [C-2] and CALL
FORWARDING - DONT ANSWER [C-3] combination:
Although CALL FORWARDING - ALL CALLS [C-5], CALL FORWARDING - BUSY LINE [C-2] and
combinations of the two are limited to forwarding five times, when a sequence of forwards is divided by
CALL FORWARDING - DONT ANSWER [C-3], CALL FORWARDING - ALL CALLS [C-5] and
CALL FORWARDING - BUSY LINE [C-3], forwards can begin again (the only limit is shown below).
8. Forwarding to an Attendant Console: 
a.) If an Attendant Console is designated as the destination of CALL FORWARDING - ALL
CALLS [C-5], the call is forwarded to the Attendant Console handling the tenant to which the
calling station belongs.

Service Conditions (cont’d)
b.) The Attendant Console key that lights when a call is forwarded to the console depends on the
forwarding status of the originally called station (except in paragraph c). The following table
shows the key that will light; e.g., the BUSY key will light, if the forwarding status of the
originally called station is CALL FORWARDING - BUSY LINE [C-2], and the call is from a
station.
c.) If the call is forwarded by CALL FORWARDING - DONT ANSWER [C-3] at any point in a
forwarding sequence, the NANS key on the Attendant Console will light, even if the call status of
the originally called station is CALL FORWARDING - ALL CALLS or CALL FORWARDING
- BUSY LINE.
d.) Called Number Display is only provided if a call is forwarded to the Attendant Console by CALL
FORWARDING - ALL CALLS [C-5] or by CALL FORWARDING - BUSY LINE [C-2].
9. Forwarding to a D
term:
a.) The calling D
terms display will show the number of the called station on the left, and the number
of the station being called on the right. The display on the ringing Dterm will show the number of
the originally called station on the left, and the number of the calling station on the right.
b.) The forward status of the originally called station is shown on the far left of each D
terms display:
FDB for CALL FORWARDING - BUSY LINE [C-2]; FDA for CALL FORWARDING - ALL
CALLS [C-5].
10. UCD Groups: 
a.) If the destination of a CALL FORWARDING - ALL CALLS [C-5], CALL FORWARDING -
BUSY LINE [C-2], or CALL FORWARDING - DONT ANSWER [C-3] is a UNIFORM CALL
DISTRIBUTION (UCD) [U-1] group control station, and CALL FORWARDING - ALL CALLS
[C-5] is not set at that station, the call will be forwarded according to UCD [U-1] procedures. 
b.) In the UCD procedure, if CALL FORWARDING - ALL CALLS [C-5] is set on a station in the
group, that station is skipped.
11. Hunting:
a.) If the final destination station is busy, or if some condition prevents the call from being
forwarded, a busy line is selected, and a hunting check is performed.

Service Conditions (cont’d)
b.) If a call is forwarded by CALL FORWARDING - BUSY LINE [C-2] to stations that are
members of hunting groups, a hunting check is performed on the busy line closest to the called
station, or on the busy line closest to the final forward destination. In the diagram below, a
hunting check is performed on Hunt Groups 1 or 4. A hunting check is never performed on
Groups 2 or 3.
12. Busy Services, such as, EXECUTIVE OVERRIDE [E-1], CALL BACK [C-1], etc.:
a.) Busy service is provided to the busy line closest to the originally called station.
13. DIT, NIGHT CONNECTION - FIXED [N-1]:
a.) For CALL FORWARDING - ALL CALLS [C-5] and CALL FORWARDING - BUSY LINE [C-
2], a forwarding check is made up to 5 times by System Data.
b.) If a line is busy in DIRECT-IN TERMINATION [D-7], CALL FORWARDING - BUSY LINE
[C-2] to the Attendant is not activated. Instead, the destination for the call can be specified by
System Data:
System Data 2 INDEX = 11
Bit 7 = 0 - Call is routed to the Attendant Console 
Bit 7 = 1 - Call is placed in queue until the called station becomes idle.
14. When activating this feature via FCCS, a telephone number must be set to the call forwarding destination.
15. When activating this feature via FCCS, a call cannot be forwarded more than five times.
16. When activating this feature via FCCS, the number of times is assigned by system data.
17. The OAI monitor number and the ACD pilot number cannot be assigned as the Call Forwarding target
telephone number.
Interactions
1. Users are unaccustomed to hearing ringback tone when responding to their own station’s ring. Be sure to
inform users when providing ringback tone with MULTIPLE CALL FORWARDING-ALL CALLS in
System Data 1, Index 69, Bit 1.
2. MULTIPLE CALL FORWARDING can only be activated from an idle station.
3. When CALL WAITING [C-12, 31] ATTENDANT CAMP-ON WITH TONE INDICATION [A-1], and
CALL BACK [C-1] is directed toward Station A with CALL FORWARDING set to Station B, Station B
will receive CALL WAITING tones.

Interactions (cont’d)
4. When a station in a STATION HUNTING [S-7, 8, 9] group initiates MULTIPLE CALL FORWARDING-
ALL CALLS, calls normally destined for this station will not be received. The hunt group operates as if
the station were busy. 
5. A noncontrolling UCD station is allowed to activate CALL FORWARDING [C-5]. With this station call
forwarded, only calls dialed directly to this station are call forwarded. The member station is removed
from the UCD group under the conditions of this call forwarding feature. 
6. If an Attendant attempts BUSY VERIFICATION [B-3] to Station A, which has MULTIPLE CALL
FORWARDING-ALL CALLS set to Station B, BUSY VERIFICATION proceeds as if the Attendant had
attempted to verify Station B. If Station A has set MULTIPLE CALL FORWARDING-ALL CALLS to
the Attendant Console [A-3], BUSY VERIFICATION [B-3] is allowed at Station A, if Station A is busy. 
7. When MULTIPLE CALL FORWARDING-ALL CALLS is in effect, the activating station may be used
to originate calls. See System Data 2, Index 6, Bit 4.
8. When a station is call forwarded, the destination station is recorded for STATION MESSAGE DETAIL
RECORDING [S-10].
9. MULTIPLE CALL FORWARDING-ALL CALLS can be overridden, allowing Station B to initiate or
transfer calls back to Station A. 
10. STATION-TO-STATION CALLING [S-11] must be provided first.

term can be assigned a manual SIG key.
3. One destination station can be assigned for manual signaling through the MAINTENANCE
ADMINISTRATION TERMINAL (MAT) [M-18].
