ISDN Call Waiting is not available

The DIVA T/A’s Call Waiting is enabled

But both B-channels are in use

The second call receives a busy signal, as the DIVA T/A’s internal Call Waiting requires a free B-channel in order to hold the call.

ISDN Call Waiting is not available

You will hear a Call Waiting alert.

The DIVA T/A’s Call Waiting is enabled

The second call occupies the available B-channel.

Note on Call Bumping

If ISDN Call Waiting is disabled, Call Bumping will not occur, as MultiLink PPP uses the Call Waiting signalling information from your service provider to determine if it should release a B-channel to accomodate an incoming voice call. For more information on Call Bumping, see “General Tab” on page 38.
