AN ANALOG TRUNK MATCHING SYSTEM OF SWITCHING SYSTEM

摘要

The analog relay matching device includes a transmission line (5) that provides matching with two wires or three wires type, an input/ output relay circuit (2) and re-signal detecting circuit (4) connected to the transmission line, a common control circuit (1) connected to the input relay circuit, a matching device (8) coupled to the time switch and sub-highway of 2.048 Mbps velocity, a process matching device (7) for controlling the analog relay line matching device coupled to the output line of the common control circuit (1).
