Voice calls

Place an outgoing call by dialing an idle ISDN BRI or a non-ISDN
BRI terminal.

Complete this outgoing call and hang up.

Have another ISDN BRI or non-ISDN BRI terminal call while the first
call is still on hold.

Answer the incoming call and place it on hold.

Retrieve the call first held.

Complete the call and hang up.

Retrieve the second call on hold.

Complete the call and hang up.

—End—

This test can be repeated for terminals connected to the same DSL, different
DSLs on the same card, different DSLs on cards associated with different
MISPs/BSRCs, and between ISDN BRI and non-ISDN BRI terminals.

Call Waiting

Call Waiting informs an ISDN BRI terminal user engaged in an active call
that a call is waiting to be answered. A call setup message is sent to a DSL
when both B-channels are busy and an incoming call is in progress. This
causes a warning tone to the terminal speaker. To accept the new call, the
user must place the currently active call on hold or release the call.

Call Waiting is activated only if Hunting is not enabled or fails to handle
the incoming call. The incoming call may originate from an ISDN BRI or
a non-ISDN BRI terminal.

Note: The following test requires that the terminal receiving the second
(call waiting) call has multiple DN appearances. Otherwise, this test
will fail.
