Access Rights Class (ARC): type of access to a DECT network, such as public, residential or private

Access Rights Identity (ARI): globally unique identity that shows the access rights related to a service provider

algorithm: mathematical process or function that transforms an input into an output

algorithm identifier: designator to show which algorithm is in use, so that the correct one may be chosen

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

attach: process whereby a Portable Part (PP) within the coverage area of a Fixed Part (FP) to which it has access rights,

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

authentication (of a subscriber): process whereby a DECT subscriber is positively verified to be a legitimate user of a

authentication of user: process whereby a DECT user is positively verified to be a legitimate user of a particular FP

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

C-plane: control plane of the DECT protocol stacks, which contains all of the internal DECT protocol control, but may

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

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

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

Connection Less mode (C/L): transmission mode that transfers one packet (one self-contained unit) of data from one

Connection Oriented mode (C/O): transmission mode that transfers data from one source point to one or more
