scope:

The present document specifies the additional requirements to the existing Global System for Mobile communications (GSM) and Digital Enhanced Cordless Telecommunication (DECT) standards needed for DECT/GSM Dual Mode Terminals (DMTs) that can be switched manually between DECT and GSM mode and/or can perform background scanning and switch automatically between GSM and DECT modes and/or can have both GSM and DECT modes activated at the same time. For the DECT side, the DECT/GSM Interworking Profile (IWP) is not considered.
