Digital Enhanced Cordless Telecommunications (DECT); Common Interface (CI); Part 2: Physical Layer (PHL)
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 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)
Ta dokument je eden od delov specifikacije skupnega vmesnika (CI) za digitalne izboljšane brezvrvične telekomunikacije (DECT).
Ta dokument določa ureditve fizičnega kanala. Fizični kanali digitalnih izboljšanih brezvrvičnih telekomunikacij so poti radijske komunikacije med dvema radijskima končnima točkama. Radijska končna točka je del fiksne strukture, tj. fiksni del (FP) v zasebni lasti – običajno bazna postaja, ali prenosni del (PP) – običajno slušalka. Dodelitev enega ali več določenih fizičnih kanalov klicu je opravilo, ki ga izvajajo višje plasti.
Fizična plast (PHL) je povezana s plastjo krmiljenja dostopa do prenosnega medija (MAC) in entiteto upravljanja nižjih plasti (LLME). Na drugi strani fizične plasti je medij za radijski prenos, ki je namenjen obsežni skupni uporabi več uporabnikov digitalnih izboljšanih brezvrvičnih telekomunikacij in različnim radijskim storitvam. Opravila fizične plasti je mogoče združiti v pet kategorij:
a) modulacija in demodulacija radijskih nosilcev z bitnim pretokom določene stopnje za ustvarjanje radiofrekvenčnega kanala;
b) pridobivanje ter vzdrževanje bitne in režne sinhronizacije med oddajniki in prejemniki;
c) oddajanje ali prejemanje določenega števila bitov ob zahtevanem času in na določeni frekvenci;
d) dodajanje in odstranjevanje polja sinhronizacije in polja Z, ki se uporablja za zaznavanje trka v zadnji del vozila;
e) opazovanje radijskega okolja za sporočanje moči signala.
Ta dokument vključuje novo generacijo digitalnih izboljšanih brezvrvičnih telekomunikacij, nadaljnji razvoj standarda za digitalne izboljšane brezvrvične telekomunikacije, ki uvaja širokopasovni govor, izpopolnjene podatkovne storitve, nove tipe rež in druge tehnične izpopolnitve.

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 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.

ETSI ETSI EN 300 175-2 V2.6.1 (2015-07) 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 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. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
