Digital Enhanced Cordless Telecommunications (DECT) - Common Interface (CI) - Part 3: Medium Access Control (MAC) layer

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 Medium Access Control (MAC) layer. The MAC layer is part 3 of the DECT Common Interface standard and layer 2a of the DECT protocol stack. It specifies three groups of MAC services:
- the broadcast message control service;
- the connectionless message control service; and
- the multi-bearer control service.
It also specifies the logical channels that are used by the above mentioned services, and how they are multiplexed and mapped into the Service Data Units (SDUs) that are exchanged with the Physical Layer (PHL).
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) - 3. del: Plast krmiljenja dostopa do prenosnega medija (MAC)

Pričujoči dokument je eden izmed delov specifikacije skupnega vmesnika (CI) digitalne izboljšane brezvrvične telekomunikacije (DECT).  Ta del CI DECT določa plast krmiljenja dostopa do prenosnega medija (MAC). Plast MAC je 3. del standarda skupnega vmesnika DECT in plast 2a protokolnega sklada DECT. Določa tri skupine storitev MAC:
- storitev za nadzor sporočil za oddajanje;
- storitev za nadzor sporočil brez povezave; in
- storitev za nadzor več nosilcev.
Prav tako določa logične kanale, ki jih uporabljajo zgoraj omenjene storitve, in način multipleksiranja in mapiranja v podatkovnih enotah storitev (SDU) ki se izmenjujejo z fizično plastjo (PHL).
