CALL FORWARDING SUPPLEMENTARY SERVICE (SS-CF) WITH REROUTING
6. When there is no route that supports Q-SIG, IS-11572 protocol in the route selection data from a calling
party to a called station, Call Forwarding service is activated without rerouting function.
In this example, since the Q-SIG, IS-11572 line cannot be selected for a route from Station A (calling  
station) to Station C (forwarded station), rerouting function is not activated even if RT1 or RT2 is idle.

CALL FORWARDING SUPPLEMENTARY SERVICE (SS-CF) WITH REROUTING
7. Reestablished route is decided by the routing selection pattern data programmed at the office where the
calling party is accommodated or the gateway PBX office to the called station. Therefore, the improper route
or the route that is the same as before rerouting function may be selected depending on the office data.
For Examples 1) through 4), see the figure below.
For Example 5), see the figure below.

Example 1) the most proper routing is selected by the office data 
Routing selection data to Office “83” programmed at Office “81”:  1st RT 2,  2nd RT1, 3rd RT 3 
RT2 is selected by rerouting function after Call Forwarding is successful.
Example 2) the improper routing is selected by the office data 
Routing selection data to Office “83” programmed at Office “81”:  1
st RT 1,  2nd RT2, 3rd RT 3 
RT1 is selected by rerouting function after Call Forwarding is successful.
Example 3) the improper routing is selected because of alternate routing 
Routing selection data to Office “83” programmed at Office “81”:  1
st RT 2,  2nd RT1, 3rd RT 3 
All trunks of RT2 (the first choice) are busy. 
RT1 is selected for alternate routing after Call Forwarding is successful.
Example 4) the improper routing is selected because of the difference of protocol 
Routing selection data to Office “83” programmed at Office “81”:  1
st RT 2,  2nd RT1, 3rd RT 3 
RT2 (the first choice) is ACIS/CCIS line (not Q-SIG or IS-11572 line). 
RT1 is selected for alternate routing after Call Forwarding is successful.
Example 5)  the rerouting pattern is not changed from that before rerouting function.

CALL FORWARDING SUPPLEMENTARY SERVICE (SS-CF) WITH REROUTING
4. Interactions
Call Forwarding-Supplementary Service
1. When CALL COMPLETION ON NO REPLY (CCNR) is used with this feature that conforms to Q-SIG:
Note:CCNR available for the Q-SIG network.
SS-CFU: CCNR is not available for the station to be set the SS-CFU.
SS-CFB: CCNR is activated against the forwarding station (called station) even when the feature is set to
the station to be set SS-CFB.
SS-CFNR: CCNR is activated against the forwarded station no matter when (before or after Call Forward-
ing) the CCNR is set.
2. When CALL COMPLETION TO A BUSY SUBSCRIBER (CCBS) is used with this feature that conforms
to Q-SIG:
Note:CCNR available for the Q-SIG network.
SS-CFU: CCNR is not available for the station to be set the SS-CFU
SS-CFB: CCNR is activated against the forwarding station (called station) even when the feature is set to
station to be set SS-CFB (If the forwarding station is busy at that time, CCBS is restricted).
3. When CONNECTED NAME IDENTIFICATION PRESENTATION (CONP) is used together with this
feature;
SS-CFU: if the name information has been programmed, CONP is not effective and the connected party
name is displayed followed by the name information programmed with SS-CFU data.
SS-CFB: if the name information has been programmed, CONP is not effective and the connected party
name is displayed followed by the name information programmed with SS-CFB data.
SS-CFNR: if the name information has been programmed, CONP is not effective and the connected party
name is displayed following by the name information programmed with SS-CFNR data.
4. When CALL WAITING - TERMINATING [C-12] is used together with this feature;
When automatic CALL WAITING - TERMINATING is set to the station that has already been set this
feature, this feature has priority over CALL WAITING - TERMINATING service and the call is forwarded.
5. When DO NOT DISTURB [D-11D] service is used together with this feature;
SS-CFU: If incoming calls are terminated at the station to be set both features (SS-CFU and DND), the
calls are forwarded by the SS-CFU data.
SS-CFB: If incoming calls are terminated at the station to be set both features (SS-CFB and DND), the
calls are forwarded by the SS-CFB data.
SS-CFNR: If incoming calls are terminated at the station to be set both features (SS-CFNR and DND), the
DND service takes priority and the caller hears the reorder tone.
6. When OUTGOING TRUNK QUEUEING [O-2] service is used with this feature;
When the call is forwarded to the trunk by the SS-CF service and the destination trunk is busy, OGQ service
is not effective if the Automatic OGQ is available (the call continues to place at the trunk).

CALL TRANSFER SUPPLEMENTARY SERVICE (SS-CT) WITH REROUTING
C-159 CALL TRANSFER SUPPLEMENTARY SERVICE (SS-CT) WITH REROUTING
1. General Description
This feature provides CALL TRANSFER activated to be followed by IS-13869/ETS 300 260 protocol (SS-CT).
By using this feature, the station can hold the handling call to transfer to the remote terminal. Also, rerouting
function is activated with SS-CT service.
The functions of this feature are as follows.
1. Call Transfer-Supplementary Service
Example) Station A: Calling Party
Station B: Called Party (Forwarding Party)
Station C: Forwarded Party
(a) When the intermediate party is disconnected after the forwarded party answers the call.
(1) Station B holds a call from Station A.
(2) Station B calls to Station C and Station C answers the call.
(3) Station A connects to Station B as Station B is disconnected
(b) When the intermediate party disconnects before the forwarded party answers the call (BLIND
TRANSFER)
(1) Station B holds a call from Station A.
(2) Station B places a call to Station C
(3) Station B disconnects and the tone that Station A receives changes from the hold tone to the ring
back tone.
(4) Station A connects with Station C.

CALL TRANSFER SUPPLEMENTARY SERVICE (SS-CT) WITH REROUTING
2. Operating Procedure
This feature is operated when the station is in the two-party connection
[Set the service]
1. The station user performs the switch hook flash; the special dial tone is heard.
2. Dial the destination’s number; the ring back tone is heard.
3. The destination party answers the call.
4. The station user replaces the handset.
Note
5. The calling party and the transferred party are connected.
Note:The user may replace the handset before the transferred party answering the call. In that case, the caller
hears the ring back tone in place of the hold tone.
3. Service Conditions
Call Transfer-Supplementary Service
1. This service is available for D
term, the analog station, ISDN terminal, PCS terminal, or the attendant console.
2. This feature is available with IS-11572/ETS 300 172 interface.
3. Available Bearer Capability information for this service is speech and 3.1 kHz audio.
4. When the transferring party gets into a conversation with the destination party after the destination answers
the call, the switch hook flash may use to switch the connected party to the held party.
5. If the transferring party hangs up before the destination answers the call (transfers in the way of BLIND
TRANSFER) and transferred party is busy, the transferring party will be recalled.
6. If the call is transferred to release from the connection after the destination answers the call, the switchhook
flash is available for the transferring party to place back the original connection since the destination is busy.
(One digit dialing is not available for this operation)
7. When the transferring station is released from the connection after flashing the switchhook and hears the
special dial tone (before dialing the destination’s number), the caller hears the reorder tone. In this case, the
transferring station is not recalled.
8. When the call transfer service is not available because of Register Prepause Timer time out or Register Inter-
Digit Timer time out, the transferring party hears the reorder tone. In this case, the transferring party can
perform the switchhook flash to reconnect with the calling party.
9. In this service, incoming call via the COT cannot be transferred by the way of BLIND TRANSFER service
(When IS-11572 is interworked with ACIS, this service to be operated by BLIND TRANSFER method is
not available).
10. When the service is used to be interworked with the interface except IS-11572 or Q-SIG, the displayed
number will not be changed at the calling station (The display is the same as before the SS-CT service is
activated and the LCD of calling station displays the called station (forwarding party)). However, the LCD
of destination displays the calling station.
