S-96 Sub Address - Present
General Description
This ISDN feature allows a PRIMARY RATE INTERFACE ISDN trunk to transfer the called party sub-address
information to a destination ISDN station when the call is originated via the NEAX2400 IPX. This feature requires
dialing of the called party telephone number and the called party sub-address.
Operating Procedure
The calling station dials the ISDN subscriber number (including access code) followed by an asterisk (*), then dials
the called party sub-address followed by a pound (#).
ISDN automatically recognizes the sub-address and transfers this information to the destination party.
Service Conditions
1. If the calling party fails to dial the called party sub-address, ISDN does not transfer any called sub-address
information to the destination party.
2. If the calling party does not wish to provide a called party sub-address, the call must terminate with a #
(Timing Start). If a # is not entered, a Timing Start operation begins. The Timing Start uses the interdigit
time-out operation.
3. Sub-address dialing is available only on those telephone terminals that can generate push button (DTMF)
signals.
4. The called party number and called party sub-address must not exceed 28 digits and an asterisk (*) and/or
a pound (#).
5. Whether a called party sub-address can be dialed or not is determined by the access code. If the access
code is 9, the called party sub-address can be dialed. If the access code is 8, the called party sub-address
cannot be dialed.
6. This feature cannot be used when a call is originated to ISDN using Speed Calling or Call Forwarding
features.
