Purpose and Scope

This document specifies an Intersystem Link Protocol (ISLP) for circuit-mode data services. These data services include Asynchronous Data (ADS) and Group-3 Fax as specified in IS-99 [2] and IS-135 [4]. The ISLP adapts between air-interface data rates and higher-speed intersystem rates. The ISLP may be used between a serving system and an anchor system, possibly through one or more tandem systems.

This document comprises the following sections:

• § 2 provides an overview.

• § 3 specifies ISLP structure and processes.

• § 4 specifies ISLP enabling and disabling procedures.

• § 5 specifies terminology.

• § 6 lists references.
