Radio Equipment and Systems (RES); Digital Enhanced Cordless Telecommunications (DECT); Data Services Profile (DSP); Generic Data Link Service; Service Type C@ Class 2
This European Telecommunication Standard (ETS) defines a profile for Digital Enhanced Cordless Telecommunications (DECT) systems conforming to ETS 300 175@ Parts 1 to 9 [1] to [9]. It is part of a family of profiles which 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 specifies a Link Access Protocol (LAP) service suitable for non-transparent transfer of character-oriented or bit-oriented data streams and intended for use in private and public roaming applications. It builds upon the generic frame relay service offered by the Data Services Profile (DSP) base standard (Type A and Type B services) and adds full Data Link Control (DLC) functionality to the basic service. Annexes to this ETS contain interworking conventions to specific character orientated services. This ETS defines the Type C Service@ Mobility Class 2. The Type C service is fully compatible with both the Type A and Type B services defined in ETS 300 435 [11]. This ETS defines the additional requirements on the Physical Layer (PHL)@ Medium Access Control (MAC) layer@ DLC layer and Network (NWK) layer of DECT. The standard also specifies Management Entity (ME) requirements and generic Interworking Conventions (IC) which ensure the efficient use of the DECT spectrum.
