APPARATUS FOR INTERFACING T1-MODE PCM REPEATER AND A TELECOMMUNICATION SYSTEM

摘要

The T1 junction line matching board assembly for providing the matching between the T1 mode PCM junction line and the system comprises; a TSU matching means (1) receiving a clock for time switch terminal, sub-highway bit stream telecommunication of 1.544 MbPS speed, and data transmission; a T/S switch means (2) for exchanging and assigning the stream slots by controlling of firm ware (F/W) connected to the TSU matching means; a DTI hybrid means (3) for processing the T1 attendent function; a line matching means (4) receiving/transmitting the bipolarity PCM data with AMI line code, which is connected to the DTI hybrid means; an OBP circuit operating the system by controlling of microprocessor; a buffer (6) for reading/writing the error state.
