SIST EN 300 175-2 V2.3.1:2010
(Main)The present document is one of the parts of the specification of the Digital Enhanced Cordless Telecommunications (DECT) Common Interface (CI). This part of the DECT CI specifies the physical 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 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 extensively 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 synchronization 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 strengths.
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.
Digitalne izboljšane brezvrvične telekomunikacije (DECT) - Skupni vmesnik (CI) - 2. del: Fizična plast (PHL)
Pričujoči dokument je eden izmed delov specifikacije skupnega vmesnika (CI) digitalne izboljšane brezvrvične telekomunikacije (DECT). Ta del CI DECT določa dogovore fizičnih kanalov. fizični kanali DECT so radiokomunikacijske poti med dvema radijskima končnima točkama. Radijska končna točka je ali del fiksne infrastrukture, fiksni del v zasebni lasti (FP), praviloma bazna postaja, ali prenosni del (PP), praviloma slušalka. Dodelitev enega ali več določenih fizičnih kanalov na klic je naloga višjih plasti. Fizična plast (PHL) se povezuje z plastjo krmiljenja dostopa do prenosnega medija (MAC) in z nižjo plastjo upravljanja entitet (LLME). Na drugi strani PHL je medij za radijsko oddajanje, ki mora biti široko deljen z ostalimi uporabniki DECT in širokim naborom drugih radijskih storitev. Naloge PHL se lahko združijo v 5 kategorij:
a) moduliranje in demoduliranje radijskih nosilcev z bitnim tokom določene stopnje za izdelavo radijskega frekvenčnega kanala;
b) zagotavljanje in vzdrževanje bita in režo sinhronizacije med oddajniki in sprejemniki;
c) oddajanje in sprejemanje določenega števila bitov ob zahtevanem času in na določeni frekvenci;
d) dodajanje in odvzemanje sinhronizacijskega polja in Z-polja, uporabljenega za odkrivanje trkov v zadnji del;
e) opazovanje radijskega okolja za poročanje o jakostih signala.
Pričujoči dokument vsebuje DECT nove generacije, nadaljnji razvoj standarda DECT, ki predstavlja širokopasovni govor, izboljšane podatkovne storitve, nove vrste rež in druge tehnične izboljšave.
