PURPOSE:To easily acquire direct charging information or the like to a sender source terminal equipment by inserting a logical address of a caller network name and a caller terminal equipment forcibly into a call request text in an inter-network connector of a network applying calling. CONSTITUTION:A call request text CR is received by an MAC-LLC-X.25 PLP circuit 2-5 via a LAN 1-1. Then a sender source address SA of a received text is used as a key to retrieve a MAP memory 2-3. Then a MAP memory management circuit 2-4 gives an issue command of an incoming reception text CA to the MAC-LLC-X.25 PLP circuit 2-5. Thus, the data text DT is described with the sender source address SA of the header part and a destination address DA is described for the message part, similarly in the case of the cell request text CR, a LAN pass word, a destination network name, a destination address and a communication end scheduled month/date/time/minute.
