antenna properties such as gain, polarization, coverage patterns and other features that may affect the practical coverage
NOTE: A typical example is space diversity, provided by two vertically polarized antennas separated by 10 cm to
20 cm.

algorithm
Cipher Key (CK) generation: process for generating cryptographic keys
ciphertext: output of a cryptographic algorithm

cluster: logical grouping of one or more cells between which bearer handover is possible
confidentiality: rendering information secret as ciphertext unless the capability is possessed to recover the plaintext
from ciphertext
connection: See MAC connection.

For the purposes of the present document, the following terms apply:
Access Rights Class (ARC): type of access to a DECT network, such as public, residential or private
Access Rights Details (ARD): unique number within one ARC
Access Rights Identity (ARI): globally unique identity that shows the access rights related to a service provider

antenna diversity: diversity implies that the Radio Fixed Part (RFP) for each bearer independently can select different
antenna properties such as gain, polarization, coverage patterns and other features that may affect the practical coverage
NOTE: A typical example is space diversity, provided by two vertically polarized antennas separated by 10 cm to
20 cm.
asymmetric algorithm: See public key algorithm.
attach: process whereby a Portable Part (PP) within the coverage area of a Fixed Part (FP) to which it has access rights,
notifies the FP that it is operative
authentication: corroboration that an entity is the one that is claimed
authentication of Fixed radio Termination (FT): process whereby the identity of an FT is verified to a DECT PT
authentication of Portable radio Termination (PT): process whereby a DECT PT is positively verified to be a
legitimate user of a particular FP
authentication (of a subscriber): process whereby a DECT subscriber is positively verified to be a legitimate user of a
particular FP
authentication of user: process whereby a DECT user is positively verified to be a legitimate user of a particular FP
bearer: See Medium Access Control (MAC) bearer or bearer service.
bearer handover: internal handover process provided by the MAC layer, whereby one MAC connection can modify its
underlying bearers while maintaining the service provided to the Data Link Control (DLC) layer
bearer service: type of telecommunication service that provides a defined capability for the transmission of signals
between user-network interfaces
broadcast: simplex point-to-multipoint mode of transmission
C-plane: control plane of the DECT protocol stacks, which contains all of the internal DECT protocol control, but may
also include some external user information
call: all of the Network (NWK) layer processes involved in one NWK layer peer-to-peer association
cell: domain served by a single antenna(e) system (including a leaky feeder) of one FP
Central Control Fixed Part (CCFP): physical grouping that contains the central elements of a FP
centrex: implementation of a private telecommunication network exchange that is not located on the premises of the
private network operator
Cipher Block Chaining Message Authentication Code (CBC-MAC): cryptographic technique for constructing a
message authentication code from a block cipher
Cipher Key (CK): value that is used to determine the transformation of plaintext to ciphertext in a cryptographic
algorithm
Cipher Key (CK) generation: process for generating cryptographic keys
ciphertext: output of a cryptographic algorithm
channel: See physical channel.
cluster: logical grouping of one or more cells between which bearer handover is possible
confidentiality: rendering information secret as ciphertext unless the capability is possessed to recover the plaintext
from ciphertext
connection: See MAC connection.
connection handover: internal handover process provided by the DLC layer, whereby one set of DLC entities (C-plane
and U-plane) can re-route data from one MAC connection to a second new MAC connection, while maintaining the
service provided to the NWK layer

Connection Less mode (C/L): transmission mode that transfers one packet (one self-contained unit) of data from one
source point to one (or more) destination points in a single phase
Connection Oriented mode (C/O): transmission mode that transfers data from one source point to one or more
destination points using a protocol based on three phases:
• "Set-up";
• "Data transfer"; and
• "Release".
Cordless Radio Fixed Part (CRFP): Wireless Relay Station (WRS) that provides independent bearer control to a PT
and FT for relayed connections

confidentiality
countermeasure: device, instrument or procedure used to counter

For the purposes of the present document, the following terms apply:
Access Rights Class (ARC): type of access to a DECT network, such as public, residential or private
Access Rights Details (ARD): unique number within one ARC
Access Rights Identity (ARI): globally unique identity that shows the access rights related to a service provider

antenna diversity: diversity implies that the Radio Fixed Part (RFP) for each bearer independently can select different
antenna properties such as gain, polarization, coverage patterns and other features that may affect the practical coverage
NOTE: A typical example is space diversity, provided by two vertically polarized antennas separated by 10 cm to
20 cm.
asymmetric algorithm: See public key algorithm.
attach: process whereby a Portable Part (PP) within the coverage area of a Fixed Part (FP) to which it has access rights,
notifies the FP that it is operative
authentication: corroboration that an entity is the one that is claimed
authentication of Fixed radio Termination (FT): process whereby the identity of an FT is verified to a DECT PT
authentication of Portable radio Termination (PT): process whereby a DECT PT is positively verified to be a
legitimate user of a particular FP
authentication (of a subscriber): process whereby a DECT subscriber is positively verified to be a legitimate user of a
particular FP
authentication of user: process whereby a DECT user is positively verified to be a legitimate user of a particular FP
bearer: See Medium Access Control (MAC) bearer or bearer service.
bearer handover: internal handover process provided by the MAC layer, whereby one MAC connection can modify its
underlying bearers while maintaining the service provided to the Data Link Control (DLC) layer
bearer service: type of telecommunication service that provides a defined capability for the transmission of signals
between user-network interfaces
broadcast: simplex point-to-multipoint mode of transmission
C-plane: control plane of the DECT protocol stacks, which contains all of the internal DECT protocol control, but may
also include some external user information
call: all of the Network (NWK) layer processes involved in one NWK layer peer-to-peer association
cell: domain served by a single antenna(e) system (including a leaky feeder) of one FP
Central Control Fixed Part (CCFP): physical grouping that contains the central elements of a FP
centrex: implementation of a private telecommunication network exchange that is not located on the premises of the
private network operator
Cipher Block Chaining Message Authentication Code (CBC-MAC): cryptographic technique for constructing a
message authentication code from a block cipher
Cipher Key (CK): value that is used to determine the transformation of plaintext to ciphertext in a cryptographic
algorithm
Cipher Key (CK) generation: process for generating cryptographic keys
ciphertext: output of a cryptographic algorithm
channel: See physical channel.
cluster: logical grouping of one or more cells between which bearer handover is possible
confidentiality: rendering information secret as ciphertext unless the capability is possessed to recover the plaintext
from ciphertext
connection: See MAC connection.
connection handover: internal handover process provided by the DLC layer, whereby one set of DLC entities (C-plane
and U-plane) can re-route data from one MAC connection to a second new MAC connection, while maintaining the
service provided to the NWK layer

Connection Less mode (C/L): transmission mode that transfers one packet (one self-contained unit) of data from one
source point to one (or more) destination points in a single phase
Connection Oriented mode (C/O): transmission mode that transfers data from one source point to one or more
destination points using a protocol based on three phases:
• "Set-up";
• "Data transfer"; and
• "Release".
Cordless Radio Fixed Part (CRFP): Wireless Relay Station (WRS) that provides independent bearer control to a PT
and FT for relayed connections
Counter with CBC-MAC (CCM): authenticated encryption algorithm designed to provide both authentication and
confidentiality
countermeasure: device, instrument or procedure used to count
