An ISDN BRI user can assign the same address or a different address for
voice or data calls being forwarded. Calls can also be forwarded to an ISDN
BRI terminal or a non-ISDN BRI terminal. When the CFU feature is
activated, outgoing calls can still be made from the ISDN BRI terminal.
The ETSI supplementary service provides Call Forwarding capabilities to all
users on the access (that is, all the DNs defined under a Digital Subscriber
Loop (DSL), or an individual user (that is, a DN).
Procedure 35
Perform an ISDN BRI ETSI Call Forwarding Unconditional test
The following test is for forwarding a voice call from an ISDN BRI M5317
set.
1 Set up ISDN BRI ETSI Call Forwarding Unconditional in Overlay 27
(refer to the "Configuring ISDN BRI features" chapter in ISDN Basic
Rate Interface: Features (553-3001-380)).
a. Select the ETSI protocol for the DSL.
b. Configure the call type (enter voice call type) and Call Forward (enter
voice call forward).
2 On the ISDN BRI terminal, configure ISDN BRI ETSI Call Forward
Unconditional.
3 Configure two DN appearances on the ISDN BRI terminal (use the first
DN to forward a call, and the second DN to place a call to test the call
forward). On some ISDN BRI terminals, the second DN appearance
allows the user to initiate the second call.
4 Activate ISDN BRI ETSI Call Forwarding Unconditional on the ISDN
BRI terminal, for the first DN:
a. Press the Forward key.
b. Dial the number where calls are to be forwarded.
c. Press the Forward key.
Note: Call Forward Reminder Tone should be provided to the ISDN
BRI terminal.
