When station-to-station connection is establi she d between a calli ng par ty and a c alle d party, the called partyand a forwarded party, rerouti ng function is not acti v ated (St ation-to-stati on connecti on in a Fusion Networkis also applied to this condition).5. When the selected route for forwarding a ca ll (from the called station to the forwarded station) is other thanQ-SIG, IS-11572 line, Call Forwarding service is activated without rerout ing function. See the fi gure belo w .
Calling Station (Station A): Office Code = 80, Statio n no. = 1000
Called Station (Station B): Office Code = 82, Station no. = 3000
Destination Station (Station C): Office Code = 83, Station no. = 4000
C.F. is set to “83-4000”

1) Station A originates a call to Station B through Office “81”. (the call is routed to Station B th rough ACIS/CCIS
and Q-SIG/IS-11572 line).
2) Since Station B is set Call Forwarding service, the call is forwarded to Station C.
3) New line from Office “81” to “83” is established for the call (RT1 is the first choice routing from Office “81” to
“83”). Rerouted line connection is Office “80” → Office “81” → Office “83”.
Note: ACIS/CCIS line (Office “80” to “81”) is not r e establis hed and Station COs number is not displayed on
the LCD of Station A belonging to Office ��80”.
In this case, rerouting function is not activated.
Station A calls to Station B, which is set C.F. service to Station C.
The call is forwarded to Station C using the protocol other than Q-SIG/IS-11572.
