PRI Connected Number Transport

PRI Connected Number Transport
The PRI Connected Number Transport feature enhances the current ISDN
functionality by way of support for the Connected Number information
element (IE) within the following messages:
For PRI agencies, enter the datafill for the Connected Number IE with a
supported action of Block (BLK) or Access Transport Parameter (ATP) as
part of the Connect, Disconnect, Release and Release Complete messages in
table ISDNPARM.
The DMS-250 switch transports the IE across the network in the
corresponding ISUP message by way of the ISUP ATP parameter after
receiving the Connected Number IE in one of the following messages:
The above only occurs if table ISDNPARM has the ATP parameter. The
Extended Peripheral Module (XPM) blocks the Connected Number IE from
the supported Q.931 message if the value in table ISDNPARM is set to
BLK.
Support for the Connected Number IE in the Connect, Disconnect, Release
or Release Complete messages does not affect support for the Connect
Number IE in the Notify message.
