IS-728 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 TIA/EIA/IS-99 and TIA/EIA/IS-135. 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 (see ANSI/TIA/EIA-41.1 for details on "serving system", "anchor system", and "tandem system").

This Recommendation specifies error performance events, parameters and objectives of a N ×64 kbit/s circuit-switched digital connection (1 ≤N ≤24 or ≤31 respectively) used for voice traffic or as a "Bearer Channel" for data-type services. The application of this Recommendation is limited to international digital connections, operating below the primary rate of the digital hierarchy, that use equipment designed prior to the adoption of revised ITU-T Rec.G.826 on 14 December 2002.

This Recommendation describes the principles, criteria and procedures for the assignment and reclamation of resources within a shared E.164 Country Code for Groups of Countries. These shared Country Codes coexist with all other E.164-based Country Codes assigned by ITU-T. The resource of the shared Country Code consists of a Country Code and a Group Identification Code (CC + GIC) and provides the capability for a Group of Countries to provide telecommunication services within the Group of Countries. TSB is responsible for the assignment of the CC + GIC.
