ABSTRACT:
Relocation and/or replacement of terminal apparatus in telecommunications systems including, but not necessarily limited to, key telephone systems, usually entails reassignment of administration data; for example, features. When a station or terminal apparatus is moved physically from one port to another within a telecommunications system which comprises a plurality of ports connected to a central processor, interface means operative on initial connection of said terminal apparatus transmits to the central processor an identifier unique to such terminal apparatus within such system. The central processing means has storage for each said identifier together with administration data specific to said terminal apparatus and the number of the port to which said terminal apparatus set is connected. Following receipt of an identifier, the central processor updates said storage means to assign said administration data corresponding to said identifier to the present port.
