The present document specifies how Integrated Services Digital Network (ISDN) services can be provided over Digital
Enhanced Cordless Telecommunications (DECT). It is based on DECT Common Interface (CI) specification
EN 300 175, parts 1 [1] to 8 [8], to enable ISDN terminals to have cordless access to an ISDN infrastructure. Both
public ISDN and private ISDN are within the scope of the present document.
The user has transparent access to the ISDN services and functions. In respect to bearer services, the following are
supported: speech, 3,1 kHz audio, unrestricted 64 kbit/s data, packet data and user signalling bearer service.
The DECT intermediate system configuration differs from the DECT end system configuration as follows. The
intermediate system is used to enable ISDN terminals to have cordless access to an ISDN infrastructure via a DECT air
interface. The end system is used where the DECT Fixed Part (FP) and the DECT Portable Part (PP) together form an
end system with the behaviour of an ISDN Terminal Equipment (TE).
