ISDN BRI National ISDN-1 Call Forward All Calls
National ISDN-1 Call Forward All Calls enables a user of an ISDN BRI
terminal to have calls redirected from the user's DN to another DN. Calls
are redirected regardless of the busy or idle status of the interface to the
user. Call Forward is assigned on the basis of the directory number and
call type (that is, the user may have voice calls forwarded, while data calls
terminate normally).

Use LD 27 to specify the HUNT parameter DNs when
configuring the DSL. These hunt parameter DNs specify
the members of a hunting chain. See "DSL configuration
procedures" in ISDN Basic Rate Interface Feature Fundamentals
(NN43001-580).
Place two calls, one for each voice ISDN BRI terminal, on a DSL
to create a DSL busy condition.
Place a voice call to one of the busy ISDN BRI terminals with
hunting enabled. Since the channel type required to handle the
incoming call type is busy, hunting is automatically invoked to
find an idle DN in the hunting chain.
The following can occur:
•
If the call finds an idle voice ISDN BRI or non-ISDN BRI
terminal, it will ring that terminal.
•
If hunting is not successful:
— the originating party receives a busy tone if the total
number of calls on the DSL (as configured on LD 27)
exceeds the maximum number of calls allowed, or
— the call is placed in call waiting if the maximum number of
calls on the DSL is below the specified limit.
•
If the call is placed in call waiting, observe the called ISDN
BRI terminal. You should get a visual indication of the next
DN and receive an audible tone.
Place the active call on hold and answer the incoming call that
is waiting.
Complete the incoming call and hang up.
Retrieve the call on hold.
Release the call connection.
