Digital Enhanced Cordless Telecommunications (DECT); Data Services Profile (DSP); Point-to-Point Protocol (PPP) Interworking for Internet Access and General Multi-Protocol Datagram Transport (V1.1.1)
The present document defines a profile for Digital Enhanced Cordless Telecommunications (DECT) systems conforming to EN 300 175@ parts 1 to 7 [1] to [7]. 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. The present document is intended for use in roaming applications and so specifies mobility class 2. It thus specifies the requirements on the Network (NWK) layer Call Control (CC) and Mobility Management (MM) entities@ to provide full public services. The present document builds upon services offered by the data service profiles as defined in ETS 300 701 [9] and ETS 300 651 [8]. It specifies an interworking profile for non-voice equipment with roaming mobility@ providing Point-to-Point Protocol (PPP) transmission to allow dial-up internet access and general multi-protocol datagram transport. PPP packet transfers on the DECT air interface are specified via a high efficient DECT packet transmission protocol. However@ interworking to the fixed network may be via a number of interface protocols@ including X.25@ frame relay@ Asynchronous Transfer Mode (ATM)@ and traditional circuit switched voice band modem and Integrated Services Digital Network (ISDN) connection. The present document defines the specific requirements on the Physical (PHL)@ Medium Access Control (MAC)@ data Link Control (DLC) and NWK layers of DECT. The standard also specifies Management Entity (ME) requirements and generic interworking conventions which ensure the efficient use of the DECT spectrum.
