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 page38.

•The second call receives a busy signal, as the DIVAT/A’s
internal Call Waiting requires a free B-channel in order
to hold the call.
