DEVICE FOR MATCHING BASE STATION OF WIRELESS SUBSCRIBER NETWORK SYSTEM

摘要

PURPOSE: A device for matching a base station of a wireless subscriber network system is provided to satisfy an E1 trunk duplexing and a PBA duplexing simultaneously and to perform an E/LAPD interface matching and an HDSL interface matching between an RP and an RPC by embodying an integrated board integrating an E/LAPD/HDSL function with a double layer. CONSTITUTION: An LAPD processing unit(140) performs an IPC communication with a main processor(110) and performs 2 process of a layer with respect to 16th channel extracted by an E1 trunk interface unit(150). An E1 trunk interface unit(150) performs a matching between a RP(100) and an E1 trunk interface unit(210) of a RPC(200) using an E1 leased circuit, and inserts and extracts 16th channel of an E1 frame for processing an LAPD. An HDSL interface unit(160) transmits an E1 between the RP(100) and an HDSL interface unit(220) using a 2W analogue line. A D/DC converter(170) supplies power sources of the LAPD processing unit(140), the E1 trunk interface unit(150), and the HDSL interface unit(160).
