ABSTRACT:
A network broadcast system having at least one local area communication network connecting apparatus which interconnects LANs and PBXs electrically connected thereto. The local area communication network connecting apparatus includes at least one LAN connecting unit, connected to a LAN for converting a LAN frame transmitted from the LAN to a cell including a VCI which identifies a desired destination of the cell, at least one PBX connecting unit, connected to a PBX for converting an audio signal from the PBX to a cell and a converting unit, connected to the LAN connecting unit, the PBX connecting unit and a plurality of output paths. The converting unit responds to a VCI in a cell transferred thereto, adds at least an output path number which identifies an output path connected between the converting unit and a desired destination of the cell and outputs the cell to the output path identified by the output path. The converting unit includes a table having a plurality of entries for establishing relationships between VCIs and output path numbers.
