ETSI ETSI EN 300 175-2 V2.7.1 (2017-11) 8 1 Scope The present document is one of the parts of the specification of the Digital Enhanced Cordless Telecommunications (DECT) Common Interface (CI). The present document specifies the physi
43、cal channel arrangements. DECT physical channels are radio communication paths between two radio end points. A radio end point is either part of the fixed infrastructure, a privately owned Fixed Part (FP), typically a base station, or a Portable Part (PP), typically a handset. The assignment of one
44、or more particular physical channels to a call is the task of higher layers. The Physical Layer (PHL) interfaces with the Medium Access Control (MAC) layer, and with the Lower Layer Management Entity (LLME). On the other side of the PHL is the radio transmission medium which has to be shared extensi
45、vely with other DECT users and a wide variety of other radio services. The tasks of the PHL can be grouped into five categories: a) to modulate and demodulate radio carriers with a bit stream of a defined rate to create a radio frequency channel; b) to acquire and maintain bit and slot synchronizati
46、on between transmitters and receivers; c) to transmit or receive a defined number of bits at a requested time and on a particular frequency; d) to add and remove the synchronization field and the Z-field used for rear end collision detection; e) to observe the radio environment to report signal stre
47、ngths. The present document includes New Generation DECT, a further development of the DECT standard introducing wideband speech, improved data services, new slot types and other technical enhancements. 2 References 2.1 Normative references References are either specific (identified by date of publi
