North America (T1) type PCM link matching device between mother country exchange and remote exchange device

摘要

The present invention relates to a remote access subscriber node (RASM) and a T1 link matching apparatus for connecting a mother-country exchange through a T1 1544-Kbps transmission line used in an existing network. The T1 link matching apparatus uses a T1 link matching board assembly A test is performed on a T1 link line and a circuit that provides a function of transmitting inter-processor communication data and service data using a 960 channel or a 40T1 T1 transmission path by connection between the matching board and a control processor and an external block It is a device that is connected to the parent station exchange by matching with the transmission device satisfying the format and transmission characteristics recommended in CCITT G. 703 and G. 733.
