scope:

This European Telecommunications Standard (ETS) describes the stage 1 of the Cordless Terminal Handover Additional Network Feature (ANF-CTH) for a Private Integrated Services Network (PISN). 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. ANF-CTH is an additional network feature that enables a Cordless Terminal Mobility (CTM) user to maintain a call while moving between overlapping location areas belonging to the same visitor area.
