ABSTRACT: Issue 10 of GR-1298, AINGR: Switching Systems, replaces Issue 9.
This document provides the generic requirements needed to implement the Advanced Intelligent Network (AIN) technology in a public
telephone network, specifically in the switching system.
GR-1298 represents the Telcordia view of the requirements needed for an AIN switching system. A Service Switching Point (SSP) is a
switch with the capability to query external service logic or databases to continue processing a call or continue offering a service to
an end user.
AIN provides the ability for service providers to create services for customers and to generate revenue. The requirements in GR-1298
allow a service provider to build AIN into a switch or interwork effectively with an AIN switch. For a supplier, GR-1298 contains the
time-tested requirements accepted as the only AIN requirements in the industry.
Key changes in Issue 10 include:
GR-1298 replaced TA-NWT-001125, TA-NWT-001298 and TR-NWT-001284.
- Requirements that allow for overflow to switch-based carrier selection when the last Trunk Group provided by the SCP encounters
- A requirement that allows operator access calls to be routed using a TrunkGroup parameter instead of only a Carrier parameter.
- Clarification to indicate that when a SDS trigger is encountered, the response, in general, should contain the
ChargePartyStationType and the Charge Number parameters.
- A requirement was modified to allow the O_No_Anser trigger to be encountered after the IN/1 routing feature when a toll-free call
