Abstract

ISDN TERMINAL EQUIPMENT OPERATING WITH
CIRCUIT SWITCHING MODE AND PACKET SWITCHING MODE

ABSTRACT OF THE DISCLOSURE

ISDN terminal equipment containing: a circuit switching communication unit, a packet communication unit, a manual starting unit, an unsuccessful try detecting unit, and a retrying unit. The manual starting unit starts an operation of a setting up of a call using a predetermined one of the circuit switching communication unit and the packet communication unit when receiving a manual start input. The unsuccessful try detecting unit detects that data communication has not been successfully begun by the operation of the manual starting unit. The retrying unit starts an operation of a setting up of a call using the other of the circuit switching communication unit and the packet communication unit when the unsuccessful try detecting unit detects that the data communication has not been successfully begun by the operation of the manual starting unit.
