Testing ISDN BRI functions

ISDN BRI ETSI Call Forwarding Unconditional

The ISDN BRI ETSI Call Forwarding Unconditional (CFU) supplementary
service allows an incoming call to an ISDN BRI terminal to be forwarded
to a predetermined destination, within or outside the system. The call is
forwarded whether the user is busy or idle.

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

Step

Action

The following test is for forwarding a voice call from an ISDN BRI M5317 set.

Set up ISDN BRI ETSI Call Forwarding Unconditional in Overlay 27
(refer to the "Configuring ISDN BRI features" chapter in ISDN Basic
Rate Interface Feature Fundamentals (NN43001-580)).

a. Select the ETSI protocol for the DSL.

b. Configure the call type (enter voice call type) and Call Forward

(enter voice call forward).

On the ISDN BRI terminal, configure ISDN BRI ETSI Call Forward
Unconditional.

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.

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.

From the second DN, place a call to the first DN, to verify that the
call ha been forwarded.
