Testing ISDN BRI functions

See "TSP configuration procedures" in ISDN Basic Rate Interface
Feature Fundamentals (NN43001-580).

From an ISDN BRI terminal with disabled hunting, dial another ISDN
BRI terminal and establish an active call connection.

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.

Place an incoming call to one of the busy ISDN BRI terminals with
disabled hunting.

Observe the called ISDN BRI terminal. The ringing or warning tone
should sound, indicating that a call is waiting.

Place the active call on hold and answer the call that is waiting.

Complete the incoming call and hang up.

Retrieve the call on hold.

Complete the call and hang up.

Call Forward No Answer

Call Forward No Answer and Second Level Forward No Answer forwards
an unanswered call to a Call Forward No Answer Directory Number (DN)
after a predetermined number of rings. This feature is enabled at the TSP
level when defining the ISDN BRI DN. Both the external and internal Call
Forward No Answer features are configured at the DSL level using LD 27.
The call can be specified to be forwarded to the attendant, to an assigned
hunting DN, or to a flexible Call Forward No Answer DN by using LD 15.

When a call originated by an ISDN BRI terminal is forwarded to a
predetermined DN specified in LD 15, the display on that ISDN BRI terminal
is not updated to indicate a call modification.
