This section defines profiles for Personal Wireless Telecommunications (PWT) Interoperability Standard conforming to ANSI/TIAIEIA 662 1998 [I]to [9]. It is part of a family of profiles that build upon and extend each other, aimed at the general connection of terminals supporting non-voice services to a fixed infrastructure, private and public.

This section specifies a generic frame relay service for use within closed user groups (CUG, see section 3 Definitions and Abbreviations). This service is used by other Data Services Profile (DSP) standards when providing inter-working to levels above the Medium Access Control (MAC) layer of the attached network. Annex B contains inter-working conventions to specific attached data networks. This includes inter-working to the MAC layer of international standard connectionless Local Area data Networks (LANs) IS0 8802.3, Ethernet and IS0 8802.5 Token Ring.

This section defines both Type A and Type B services. Type A is a low speed frame relay, with net sustainable throughput of up to 24 kb/s, optimized for burst data, low power consumption and low complexity applications such as hand-portable equipment. Service Type B is a high-speed frame relay, with a net sustainable throughput of up to 552 Wbits, optimized for high speed and low latency with burst data. Both are hilly compatible and can inter-work with each other.

This standard defines the requirements on the Physical (PHL), MAC, Data Link Control (DLC) and Network (NWK) layers of PWT.

This section also specifies Management Entity (ME) requirements and generic inter-working conventions that ensure the efficient use of the PWT frequency spectrum.
