Abstract
A private branch exchange comprises communication highways for transmitting data of a time-divisional multiplexed channels, and a time switch for switching the communication highways. A communication highway is connected to a computer network via a circuit/packet converter. Each computer terminal in the network has an extension number and Internet Protocol (IP) port addresses that differ for such communication functions as audio communication, data communication and the like. The circuit/packet converter has bearer circuits different for each communication function and allocates a specified bearer circuit to each time slot of the communication highway. When a call is originated, the circuit/packet converter controls the time slot of the communication highway such that a bearer circuit, which is vacant and suitable for a call type, is connected to the computer terminal. The bearer circuit interfaces packet data on the computer network with circuit data on the communication highway.
