User Data Features and Enhancements
Sending User Data over ISDN - Feature
Added the ability for the Adjunct to send User Data over ISDN using UUI
Information Element. User data will be sent in code set 0, using IA5 coding
standards.
Support for ISDN protocol DMS250 - Feature
Support for ISDN protocol DMS250 has been added to the TSP configurator.
The TSP has always supported the DSM250 using the generic DMS protocol
specification in the configurator. However, the DMS100 and DMS250 vary
slightly in the manner they handle the “Calling Name” field. Specifying
DMS250 for DMS 250 switches will allow better handling of this field.
