ABSTRACT:
Disclosed is a communications-exchange apparatus which can re-establish a communication link with a plurality of terminals using a re-assigned TEI after the apparatus is reset. When the exchange is reset, built-in Terminal Endpoint Identifier (TEI) management procedure execution unit 202 sets the contents of a TEI table 204 to "not-in-use" and performs a TEI check procedure on an ISDN transmission path 106. The TEI management procedure execution unit 202 sets the status of the TEI table 204 corresponding to a TEI confirmed to have been used to "in-use", or performs a TEI removal procedure.
