Digital Private Network Signaling System 1 (DPNSS1) Route
Optimization
If the call is the active call at the originating exchange and the originator
(including an AC15 trunk) has another call on hold, Route Optimization will
not be initiated.
If the call is the active call at the terminating exchange and the terminator
(including an AC15 trunk) has another call on hold, Route Optimization will
not be initiated.
If the call is held at the originating exchange (including an AC15 trunk),
Route Optimization should not be initiated. When this call is restored as
the active call, it may be optimized.
If the call is held at the terminating exchange (including an AC15 trunk),
Route Optimization may be requested by the originator, but the terminating
circuit switched network will reject it. When this call is restored as the active
call, it may be optimized.
If the call has been transferred to an already answered party (including an
AC15 trunk), the transfer signaling sequence is used to initiate optimization.
During a route optimization attempt, if an AC15 trunk is involved in the call
either at the originating or terminating exchange, a recall signal is ignored.
DPNSS1 Three-party Service
When the telephone on a Norstar system completes a call transfer between
two telephones located within a DPNSS1 network:
• DPNSS1 access restrictions are checked
• the telephones’ displays are updated, and
• DPNSS1 route optimization after transfer can be activated.
Incoming Call Indicator Enhancement
If the held party recalls the attendant due to intercept or recall treatment, the
recall is presented to the corresponding ICI key (INT or RLL).
Initialize
If initialization occurs during the three-party phase, the call on hold is
cleared. If the active call is established, it is kept, otherwise it is cleared as
well (and the AC15 trunk is idled).
MFC Signaling
AC15 trunks using MFC signaling are not supported.
