➻21-12-01 : ISDN Calling Party Number Setup for Trunks

Assign Calling Party Numbers for each trunk (maximum 16 digits per entry). When a call is made by an extension which does not have an Extension Calling Number assigned (Program 21-13-01), the sys- tem sends the calling number for the ISDN trunk defined in 21-12-01. If the Calling Party Number is assigned in both Programs 21-12-01 and 21-13-01, the system sends the data in Program 21-13-01.

Default Setting: No digits assigned.

➻21-13-01 : ISDN Calling Party Number Setup for Extensions

Assign each extension a Calling Party Number (maximum 16 digits per entry). The calling number is the subscriber number of the dial-in number. When a call is made by an extension which does not have an Extension Calling Number assigned (Program 21-12-01), the system sends the calling number for the ISDN trunk defined in Program 21-13. If a Calling Party Number is assigned in both Programs 21- 12-01 and 21-13-01, the system sends the data in Program 21-12-01.

Default Setting: No digits assigned.

➻21-15-01 : Individual Trunk Group Route for Extensions

To better control placing calls over PRI trunks, consider setting up Alternate Trunk Route Access. Use this option to specify the Alternate Trunk Route for each extension. Also see programs 11-01-01, 11- 09-02, 14-06-01.

Default Setting: No routes assigned (00).

➻22-02-01 : Incoming Call Trunk Setup

Use this option to set the service type for PRI trunks. Enter 0 (for normal operation) or 3 (if the PRI trunk has DID type operation for incoming calls).

Default Setting: All trunk service types set for normal (0).

➻81-01-01 : COIU Initial Data Setup
