This standard provides interface compatibility specifications and technical requirements for the interfacing of a Wireless Carrier to an Exchange Carrier (EC), Interexchange Carrier (IC), International Carrier (INC), Consolidated Carrier or any other carrier element.

This standard provides technical requirements for an interface that interconnects a switching system in a wireless network with a switching system in the Public Switched Telephone Network (PSTN) or a switching system in an Integrated Services Digital Network (ISDN). Within the ANSI accredited Telecommunications Industry Association (TIA) TR45 Network Reference Model, these interfaces are denoted as the A_i and D_i interfaces, respectively. For the purposes of this standard, these two interfaces are treated generically as a single interface defined concisely by a signaling protocol and by signaling information provided via that protocol.

By arranging the interface specifications into a number of individual signaling protocols, this standard provides the interconnecting network elements with a variety of compatible signaling methods to provide telecommunications services. The telecommunications services provided and, therefore, the specific interface signaling protocols available at the interface, are determined by business decisions, mutual interface agreements and legal and regulatory requirements. These decisions, agreements and requirements are beyond the scope of this technical standard.

The technical information provided in this specification complies with ANSI standard T1.104 (see Section 2 - References). Refer to this document for more details about the technical requirements of the specified internetwork interfaces.

Purpose

The purpose of this standard is to enable separate telecommunications elements to provide interconnecting equipment that will operate compatibly. Descriptions of the specific signaling characteristics of the interconnecting systems are provided in this technical standard.

This standard is a technical interface specification intended to describe interface signaling protocols between a wireless network element and other network elements. It is beyond the scope and purpose of this standard to describe or specify telecommunications services; to specify the particular interface signaling protocols that are used or not used with any telecommunications service; or to specify the performance of the telecommunications services provided using the interface signaling protocols specified in this technical standard.
