B CHANNEL PACKET CONNECTION SYSTEM WITH ISDN NETWORK

摘要

PURPOSE:To avoid the execution of communication between a packet handler and a call processing controller by devising the system such that the packet handler is able to be handled similarly as an accommodation terminal equipment of an exchange. CONSTITUTION:An ISDN trunk device 4 and plural ISDN line circuits 6-1, 6-2, 6-3 accommodating plural terminal equipments 9-1, 9-2, 9-3 are connected to an exchange 1 and an ISDN interface device 7 is connected to a packet handler 3 and an ISDN interface device 7 is connected to a required ISDN line circuit 6-3. A table 8 discriminating which of the ISDN line circuits 6-1, 6-2, 6-3 is connected to the packet handler 3 is provided to a call processing controller 2 of the exchange 1 and a line exchange call of the ISDN is identified by allowing the call processing controller 2 to reference the table 8 and the line exchange call is called to the ISDN network 5 as a B channel packet call.
