96Testing ISDN BRI functions

Procedure 33

Perform a hunting test

Step Action

1Set the FEAT parameter to HTA to enable hunting for two voice ISDN BRI terminals. Use LD 27 to specify this parameter when configuring the TSP. See "TSP configuration procedures" in ISDN Basic Rate Interface Feature Fundamentals (NN43001-580).

2Use LD 27 to specify the HUNT parameter DNs when configuring the DSL. These hunt parameter DNs specify the members of a hunting chain. See "DSL configuration procedures" in ISDN Basic Rate Interface Feature Fundamentals (NN43001-580).

3Place two calls, one for each voice ISDN BRI terminal, on a DSL to create a DSL busy condition.

4Place a voice call to one of the busy ISDN BRI terminals with hunting enabled. Since the channel type required to handle the incoming call type is busy, hunting is automatically invoked to find an idle DN in the hunting chain.

The following can occur:

If the call finds an idle voice ISDN BRI or non-ISDN BRI terminal, it will ring that terminal.

If hunting is not successful:

the originating party receives a busy tone if the total number of calls on the DSL (as configured on LD 27) exceeds the maximum number of calls allowed, or

the call is placed in call waiting if the maximum number of calls on the DSL is below the specified limit.

If the call is placed in call waiting, observe the called ISDN BRI terminal. You should get a visual indication of the next DN and receive an audible tone.

5Place the active call on hold and answer the incoming call that is waiting.

6Complete the incoming call and hang up.

7Retrieve the call on hold.

8Release the call connection.
