ABSTRACT:
In a fixed-length cell handling-type exchange, a private line connection is set by automatically reserving a usable path and a necessary band at a designated time. The exchange includes a storage unit which has a connection reservation information storage unit which stores private line connection reservation information and control unit which includes a command reception unit for receiving a command having the private line connection reservation information. A reservation information management unit stores the private line connection reservation information received by the command reception unit into the connection reservation information storage unit of the storage unit. A time information confirming unit confirms the period of the private line connection by referring to the connection reservation information storage unit at constant time intervals. The exchange further includes a private line connection control unit for automatically controlling the setting or canceling of the private line connection between the designated subscriber terminals via an exchange switching unit, based on the private line connection reservation information stored in the connection reservation information storage unit, according to the confirmation result by the time information confirming unit.
