METHOD FOR INTERFACING CHANNELS OF USER NETWORK INTERFACE IN SWITCHING SYSTEM

摘要

PURPOSE: A method for interfacing channels of a user network interface in a switching system is provided to make a primary rate interface(PRI) circuit interface an H channel without operating a B channel in a network when a subscriber requests an H channel interfacing process, so as to prevent data losses generated from synchronization disagreements caused by transmission path differences to the network and to interface the H channel as using an existing B channel path. CONSTITUTION: If an H channel interfacing request is generated from a subscriber(400), a primary subscriber control card(PSCC) matches B channels by 6 by 6(410). The PSCC selects a B channel by using a channel number requested by the subscriber(420). The PSCC connects the selected B channel only to a sub-highway(SHW)(430). The PSCC requests a time switch line(TSL) to connect the B channels inputted in the SHW to a consecutive time switch(440). The B channels are converted into logical H channels.
