Chapter 2 — Feature descriptions
553-3011-311 Standard 7.0
Call forward no answer and second level call forward no answer are activated
if FNA and SFA are selected for a DN when configuring the TSP using
Service Change ISDN BRI Program LD 27. If a call is not answered after a
predetermined timer expires, the initial call setup is released from the DSL
and call forward no answer routes the call to an alternate DN.
An ISDN BRI terminal originating the call is not updated to show on its
display that the call was redirected to a different DN as a result of call forward
no answer. This is due to lack of standard for layer 3 messages used to update
the ISDN BRI terminal display
Call Hold (not supported by 1TR6 protocol)
This feature is activated by pressing the Hold key on the terminal. This
feature allows an ISDN BRI terminal to place an active call on hold to accept
or originate another call. You can dial a new call and go back to the call on
hold.
An ISDN BRI terminal can place an ISDN BRI or non-ISDN BRI terminal
on hold.
Deluxe hold and permanent hold do not apply to an ISDN BRI terminal,
however a non-ISDN BRI terminal can place an ISDN BRI terminal in deluxe
hold or permanent hold.
Call Waiting
This feature alerts a busy ISDN BRI terminal that a call is waiting to be
answered. To answer a waiting call, the ISDN BRI terminal must place the
active call on hold or release the active call. If the ISDN BRI terminal user
tries to answer a call waiting call when no B-channel is available, the call is
released from the ISDN BRI terminal and extended to the attendant.
When both B-channels on a DSL are busy, an incoming call is presented to
the DSL as call waiting as long as the number of calls on this DSL does not
exceed the maximum number of calls specified, which include active calls,
calls waiting, and calls on hold. This maximum number of simultaneous calls
allowed is specified when configuring the DSL using Service Change ISDN
BRI Program LD 27.
A call waiting from an ISDN BRI terminal is presented to a non-ISDN BRI
terminal as a normal call waiting call.
