Abstract:
A cell relay communication method to be used in a relay system which includes a plurality of transmission devices each having a voice relay function and a cell transmission/reception control function connected to an ATM network through a cell assembly and disassembly device having a function of assembling and disassembling cells including compressed voice data, the method comprising the steps of:identifying whether a call received from said ATM network is a relay call or a locally-addressed call which is addressed to a device coupled to said each transmission device; relaying said received call by transferring a compressed voice data with respect to the received call through said transmission device by a higher data speed then a compressed voice data speed when said received call is said relay call; and transferring a compressed voice data with respect to the received call to said transmission device by the compressed voice data speed when said received call is said locally-addressed call.
