A novel scheme to access the basic rate service of the Integrated Service Digital Network (ISDN) using the Digital Enhanced Cordless Telephone (DECT) radio interface standard is presented. The S-interface in the ISDN reference configuration has been used for the ISDN interface and the unprotected class 0 transmissions are used for the DECT interface. The design of a state of the art interworking unit is described which endeavors to make the use of DECT transparent to the ISDN equipment. The complete design has been simulated and the results presented quantify the overall quality of the link for varying qualities of the radio channel. The simulation results show that DECT radio link can actually replace the fixed S-bus hence locating and relocating of terminal equipment is achieved and this can form the stepping stone for user locating in the 3G (third generation) Universal Mobile Telecommunications System (UMTS). Furthermore, the study also shows that this technique saves on the spectrum usage as it gives 20% spectrum efficiency improvement.
