Digital cellular telecommunications system (Phase 2+) (GSM); GSM Cordless Telephony System (CTS), Phase 1; CTS Architecture Description; Stage 2 (GSM 03.56 version 7.1.1 Release 1998)

Scope

The present document defines the stage 2 description for the Cordless Telephony System (CTS) based on GSM radio.
As the second stage of a three-level structure, it is derived from the stage 1 service description.
As mentioned already in the stage 1 description, a phased approach is indispensable to have an early first specification
ready for market needs. The first phase focuses on the requirements necessary to elaborate the radio interface and the
security aspects for an application supporting the speech tele-service (including DTMF support) in a residential single
cell environment.
The standardisation of the physical layers of the GSM-CTS fixed network interface is not in the scope of the present
document.
