Stage 1 is an overall service description, primarily from the service subscriber's and user's point of view, but does not deal with the details of the human interface itself. The present document includes information applicable to network operators and terminal, switch and database manufacturers. Feature Packages are offered in addition to the standard Cordless Terminal Mobility (CTM) Phase 2 service. However, for Feature Package 1 it is not necessary for the user to subscribe to the telephony service if he only requires data service applications.
