Digital Enhanced Cordless Telecommunications (DECT); Common Interface (CI); Part 5: Network (NWK) layer
ETSI EN 300 175-5 V1.8.1 (2004-11)

The present document gives an introduction and overview of the complete Digital Enhanced Cordless Telecommunications (DECT) Common Interface (CI). The present document specifies the Network (NWK) layer. The NWK layer is part 5 of the EN 300 175 and layer 3 of the DECT protocol stack.The present document only specifies the C-plane (control plane) of the DECT NWK layer. It contains no specification for the U-plane (user plane) because the U-plane is null for all services at the DECT NWK layer. The C-plane contains all of the internal signalling information, and the NWK layer protocols are grouped into the following families of procedures:
- Call Control (CC);
- Supplementary Services (SS);
- Connection Oriented Message Service (COMS);
- ConnectionLess Message Service (CLMS);
- Mobility Management (MM);
- Link Control Entity (LCE).
The present document uses the layered model principles and terminology as described in ITU-T Recommendation X.200 and ITU-T Recommendation X.210.

The present document gives an introduction and overview of the complete Digital Enhanced Cordless Telecommunications (DECT) Common Interface (CI). The present document 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).

Digital Enhanced Cordless Telecommunications (DECT); Common Interface (CI); Part 6: Identities and addressing
ETSI EN 300 175-6 V1.8.1 (2004-11)

The present document gives an introduction and overview of the complete Digital Enhanced Cordless Telecommunications (DECT) Common Interface (CI). The present document specifies the identities and addressing structure of the Digital Enhanced Cordless Telecommunications (DECT) Common Interface (CI). There are four categories of identities to be used for identification and addressing in a general DECT environment.
These four categories are:
- Fixed Part (FP) identities;
- Portable Part (PP) identities;
- connection-related identities;
- equipment-related identities.
Fixed part identities and portable part identities are used for:
- access information from fixed parts to portable parts;
- access requests from portable parts;
- identification of portable parts;
- identification of fixed parts and radio fixed parts;
- paging;
- billing.
These identities support:
- different environments, such as residential, public or private;
- supply to manufacturers, installers, and operators of globally unique identity elements with a minimum of central administration;
- multiple access rights for the same portable;
- large freedom for manufacturers, installers, and operators to structure the fixed part identities, e.g. to facilitate provision of access rights to groups of DECT systems;
- roaming agreements between DECT networks run by the same or different owners/operators;
- indication of handover domains;
- indication of location areas, i.e. paging area;
- indication of subscription areas of a public service.
The present document also provides for length indicators and other messages that can override the default location and/or paging area and domain indications given by the structure of the identities.
Connection related identities are used to identify the protocol instances associated with a call and are used for peer-to-peer communication. Equipment related identities are used to identify a stolen PP and to derive a default identity coding for PP emergency call set-up.
Coding of identity information elements for higher layer messages is found in EN 300 175-5 [5], clause 7.7.
User authentication and ciphering need additional key information and is outside the scope of the present document, but is covered in other parts of EN 300 175 parts 1 to 8 [1] to [7], e.g. part 7.

• large freedom for manufacturers, installers, and operators to structure the fixed part identities, e.g. to facilitate provision of access rights to groups of DECT systems;
• roaming agreements between DECT networks run by the same or different owners/operators;
• indication of handover domains;
• indication of location areas, i.e. paging area;
• indication of subscription areas of a public service.
The present document also provides for length indicators and other messages that can override the default location and/or paging area and domain indications given by the structure of the identities.
Connection related identities are used to identify the protocol instances associated with a call and are used for peer-to-peer communication.
Equipment related identities are used to identify a stolen PP and to derive a default identity coding for PP emergency call set-up.
Coding of identity information elements for higher layer messages is found in EN 300 175-5 [5], clause 7.7.
User authentication and ciphering need additional key information and is outside the scope of the present document, but is covered in other parts of EN 300 175-1 [1] to EN 300 175-8 [7], e.g. EN 300 175-7 [6].

SIST EN 300 176-2 V1.5.1:2006(Main)
Digital Enhanced Cordless Telecommunications (DECT); Test specification; Part 2: Speech
ETSI EN 300 176-2 V1.5.1 (2004-01)

The present document specifies the tests applicable to all Digital Enhanced Cordless Telecommunications (DECT) equipment accessing the DECT frequency band 1 880 MHz to 1 900 MHz (including provisions for testing other or extended frequency bands) and the tests applicable to DECT speech transmission using ITU-T Recommendation G.726 [17] ADPCM speech codec at 32 kbit/s.
The aims of the present document are to ensure:
- efficient use of frequency spectrum;
- no harm done to any connected network and its services;
- no harm done to other radio networks and services;
- no harm done to other DECT equipment or its services;
- interworking of terminal equipment via the public telecommunications network, through testing those provisions of EN 300 175, parts 1 [1] to 8 [8] which are relevant to these aims.
The tests of EN 300 176 are split into two parts:
- part 1 covers testing of radio frequency parameters, security elements and those DECT protocols that facilitate the radio frequency tests and efficient use of frequency spectrum;
- part 2 (the present document) describes testing of DECT 32 kbit/s ADPCM speech requirements between network interface and DECT PT, or between a DECT CI air interface and alternatively a DECT PT or FT.
This part is not applicable to terminal equipment specially designed for the disabled (e.g. with amplification of received speech as an aid for the hard of hearing).
DECT terminal equipment consists of the following elements:
a) Fixed Part (FP);
b) Portable Part (PP);
c) Cordless Terminal Adapter (CTA);
d) Wireless Relay Station (WRS) (FP and PP combined).
The present document is structured to allow tests of either:
a) the FP and PP together; or
b) the FP and PP as separate items.
Where the DECT FP is connected to a PSTN, and there are any peculiarities in the requirements for voice telephony, these shall be accommodated within the FP.

SIST EN 300 757 V1.5.1:2006(Main)
Digital Enhanced Cordless Telecommunications (DECT); Low Rate Messaging Service (LRMS) including Short Messaging Service (SMS)
ETSI EN 300 757 V1.5.1 (2004-09)

The Low Rate Messaging Service (LRMS), specified in the present document, provides a means for the slow, acknowledged or unacknowledged, transfer of multimedia message objects, including the Short Message Service (SMS). It provides both point-to-point and point-to-multipoint messaging. This service may be used for private and public roaming applications. The present document defines the requirements on the Physical (PHY), Medium Access Control (MAC), Data Link Control (DLC) and Network (NWK) layers of DECT. The present document also specifies management entity requirements and generic interworking conventions, which ensure the efficient use of the DECT spectrum. The present document further mandates how to implement a GSM like Short Message Service (SMS), Point-to-point (PTP), which uses a sub-set of the Low Rate Messaging Service (LRMS) mentioned before as a bearer service.
SMS-PTP includes the following two services:
- SMS Mobile Originated (SMS-MO), for transport of short messages from PT to FT;
- SMS Mobile Terminated (SMS-MT), for transport of short messages from FT to PT.
Definition of Point-To-Multipoint (PTM) SMS is outside the scope of the present document. In order to facilitate re-use of excising GSM Service Centres, the present document applies the upper GSM protocols up-to and including the GSM SMS-RP protocol. Therefore, interworking functions handling the encapsulation of GSM SMS-RP messages are specified. The SMS or LRMS applications are outside the scope of the present document. So is the network behind the FP. Any information provided concerning applications or the network behind the FP is provided for informative, descriptive reasons only.
