Calling Party Number NotiÞcation
The system can provide calling party number notiÞcation for outgoing ISDN calls. When a call is
made on an ISDN line by an extension, the system will send the identiÞcation for the extension
placing the call, if it’s programmed. If there is no Extension Calling Number assigned, the system
will send the calling number for the ISDN trunk. If both the extension and trunk information is pro-
grammed, the extension information will be sent as it takes priority.
When the option for calling party subaddress is on, the extension number will be sent as the subad-
dress information. Both the calling party number and calling party subaddress are sent in a SETUP
message as the calling party information element and a calling party subaddress information ele-
ment. Allow the system to send the subaddress by setting the following programs: 10-03-05=1, 15-
01-04=1, 20-08-13=1, 21-13-01=enter number to be sent.
Calling Line IdentiÞcation Presentation
A Class of Service option has been added which can be used to allow the Calling Party Number IE
in the Setup Message.
Calling Party Allowed or Prevented for Extension
The system now allows the Calling Party Number for outgoing ISDN calls based on the extension’s
set up in Program 15-01-04 : Basic Extension Data Setup - ISDN Caller ID. If this option is to
be enabled, then it must also be enabled for the BRI or PRI PCB in 10-03-05 : PCB Setup - CLIP
Information.
Alert Tone When S-Bus Terminal Calls Busy Extension
System software provides a program option for S-Bus terminals to determine what a user on an S-
Bus terminal will hear when a busy extension is called. The system can be programmed so the user
will hear an alert tone or be disconnected.
Release Message with Second T303 Timer
Depending on your software, the system can provide an program option for ISDN trunks can be
used to determine whether or not a release message is sent when the second T303 timer expires.
Option Added for PB Back Tone Level
An option is available in system software which can be used to adjust the PB Back Tone level when
calling an ISDN line.
Calling Party Number Option Added to DeÞne Type
System software allows the number plan type to be deÞned in programming. Previously, this was
not selectable and, depending on your software, was either set for "Unknown" or "National number
in a ISDN numbering plan" to allow the calling party information to be passed to some telcos.
With software 4.08, this option was programmable using Programs 99-01-32 and 99-01-33, allow-
ing the system to be adjusted for this setting. With software 4.93+, these programs have been
replaced by 10-03-18 and 10-03-19.
