SUBADDRESS–PRESENT

General Description

This feature allows a primary rate interface ISDN trunk to transfer the called party subaddress information to a

destination ISDN station when the call is originated by the NEAX2000 IVS

. Dialing the called party station

number and subaddress is required.

Operating Procedure

The calling station dials the ISDN subscriber number (including access code) followed by an asterisk (*), then

dials the called party subaddress followed by a pound sign (#). ISDN automatically recognizes the subaddress

and transfers the information to the destination party.

Service Conditions

1. If the calling party fails to dial the called party subaddress, ISDN cannot transfer any called party subaddress

informationtothedestinationparty.

2. If a calling party does not wish to provide a called party subaddress, the call must terminate with a pound

sign (#) (Immediate Start). If a pound sign is not entered, a Timing Start operation begins. The Timing Start

uses the interdigit time-out operation.

3. Subaddress dialing is available only on those telephone terminals that can generate push-button (DTMF)

signals.

4. The called party subaddress must not exceed eight digits.

5. The called party subaddress can be sent with trunk direct dial access.

6. This feature may cannot be used when a call is originated to ISDN using Speed Calling or Call Forwarding

features.
