scope:

This European Telecommunication Standard (ETS) describes the stage 1 of the Cordless Terminal Mobility (CTM) call handling Additional Network Features (ANF) for Private Integrated Services Networks (PISNs). It comprises two related but distinct service descriptions, Incoming CTM Call Handling Additional Network Feature (ANF-CTMI) and Outgoing CTM Call Handling Additional Network Feature (ANF-CTMO). Stage one is an overall service description from the user's point of view, but does not deal with the details of the human interface itself, see CCITT Recommendation I.130 [5].
