Radio Equipment and Systems (RES); Digital Enhanced Cordless Telecommunications (DECT); Data Services Profile (DSP); Generic Frame Relay Service with Mobility (Service Types A and B@ Class 2)
This European Telecommunication Standard (ETS) defines a profile for Digital European Cordless Telecommunications (DECT) systems conforming to ETS 300 175 parts 1 to 9 [1] 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 infra-structure@ private and public. This ETS defines the types A and B services@ mobility class 2 as referred to in ETR 185 [14]. This ETS supports the type A and B services using the frame relay service defined fully in ETS 300 435 [12]. Type A is optimized for low power and simplicity@ while type B is optimized for high speed and throughput. Both are fully compatible and can interwork with each other. This ETS is intended for use in roaming applications and so specifies mobility class 2. It therefore specifies the use of the network layer Call Control (CC) and Mobility Management (MM) entities@ and the Data Link Control (DLC) layer LAPC and Lc entities. This ETS integrates the frame relay service with a fully functional Control plane (C-plane). It therefore supports interworking with all connectionless networks supported by the type A and B mobility class 1 services while removing the restrictions of closed user group operation. It extends@ without modifying@ the interworking conventions of the type A and B mobility class 1 services. This ETS defines the specific requirements on the Physical (PHL)@ Medium Access Control (MAC)@ DLC and Network (NWK) layers of DECT. This ETS also specifies Management Entity (ME) requirements and generic Interworking conventions which ensure the efficient use of the DECT spectrum.
