AINGR: Switch - Intelligent Peripheral Interface (IPI)

ABSTRACT: Issue 8 of GR-1129, AINGR: Switch - Intelligent Peripheral Interface (IPI) replaces Issue 7.
This GR provides the Telcordia view of proposed generic requirements for an AIN Service Switching Point (SSP) to support interfaces
to an AIN Intelligent Peripheral (IP). An SSP is a switch with the capability to query external service applications or databases to
continue processing a call or continue offering a service to an end user. An AIN SSP queries AIN Service Control Points (SCPs) or AIN
Adjuncts to obtain this processing data. AIN SSP capability can reside on End Offices (EOs), Access Tandems (ATs), or EO/ATs. Due to
the SSP-IP interface, and to this connectivity of the switch with SCPs and Adjuncts, the capabilities required in this document allow
the IP to exchange data not only with the SSP but with the SCP and Adjunct via the SSP.
The IP is used to provide information to a network user and/or to collect information from a network user via a circuit-switched
bearer connection. A range of devices other than an IP may communicate with an SSP, SCP, or Adjunct by using the Intelligent Peripheral
Interface (IPI) as described in this GR. A functional model of an IP is provided to assist in describing the interfaces; it is not
intended to suggest any particular implementation.
The purpose of this GR is to inform industry, including IP suppliers, switching system suppliers, Operations System (OS) suppliers,
SCP and Adjunct suppliers, service creators, and others of the Telcordia view of proposed SSP generic requirements to support the
interface to an AIN IP. The proposed generic requirements reflect the needs of Local Exchange Carriers (LECs) that have participated
with Telcordia in this work. This GR is not intended to imply an implementation.
This GR contains the Telcordia view of proposed generic requirements for the AIN SSP for supporting:
- The interface between an IP and an AIN SSP. The interface described by the proposed generic requirements may be used by an IP
or by any other device that conforms to the interface.
- The interface between an IP and an AIN SSP to which the IP does not have a direct Integrated Services Digital Network (ISDN)
This GR also includes suggested formats for parameter encodings for:
- Certain fields in messages that are used between an SCP/Adjunct and an SSP for exchanging information with an IP.
- Certain fields in messages to support AIN operations such as maintenance (e.g., IP out of service) and security.
- Data needed for Automatic Message Accounting (AMA).
Issue 8 of GR-1129-CORE updates information in Section 4, and 5. GR-1129 replaced TA-NWT-001129 and TA-TSY-000923.
