Date Sep. 12, 1997In a communication system across an in-office PC system (10) and an in-enterprise LAN system (20), in order to perform a transmission of packet data from a DDTE (22) on the LAN side to a M-DTE (14) on the personal station side without a need of a provision of complicated means, when receiving packet data addressed to the M-DTE (14) from the DTE (22), a LAN side control unit (23) transmits a connection request including the incoming packet address to a PBX (11) of the in-office PC system (10), the PBX (11) notifies a PS (13) of the incoming signal for the packet address through a CS(12), and on the other hand, the M-DTE (14) connected to the PS (13) acknowledges the incoming signal through the PS (13) and the CS (12) when the packet address which received this notice corresponds to the M-DTE (14), thereby achieving a connection. After the connection, the control unit (23) transmits packet data to the M-DTE (14).
