Page 102 of 120 Testing ISDN BRI functions
553-3001-218 Standard 2.00 September 2004
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.
Procedure 28
Perform a Call Waiting test
1 Set the FEAT parameter to HTD to disable Hunting. Use LD 27 to
specify this parameter when configuring the Terminal Service Profile
(TSP) for the two voice ISDN BRI DNs on one of the DSLs. See “TSP
configuration procedures” in
ISDN Basic Rate Interface: Features
(553-3001-380) .
2 From an ISDN BRI terminal with disabled hunting, dial another ISDN
BRI terminal and establish an active call connection.
3 From the second ISDN BRI terminal with disabled hunting, dial another
ISDN BRI terminal and establish another active call connection. Both
B-channels on the DSL are now busy.
Note: Only two ISDN BRI terminals may be on the same DSL to allow
them to connect. The other two ISDN BRIs are on a different DSL.
4 Place an incoming call to one of the busy ISDN BRI terminals with
disabled hunting.
5 Observe the called ISDN BRI terminal. The ringing or warning tone
should sound, indicating that a call is waiting.
6 Place the active call on hold and answer the call that is waiting.
7 Complete the incoming call and hang up.
8 Retrieve the call on hold.
9 Complete the call and hang up.
