Subhighway Multiplexing and Demultiplexing Device for Electronic Switching System

摘要

According to the present invention, a device capable of accommodating 2K capacity even with a single circuit pack in a time switch device is designed by designing a 64 subhighway multiplexing and demultiplexing circuit pack that is mounted and operated in an electronic switch. The present invention provides a 64 subhighway using a Z-PACK connector having a large number of terminals to multiplex and demultiplex the 64 subhighway, and connect the multiplexing / demultiplexing unit with the relay line and subscriber matching unit. The subhighway clock and the synchronous clock are distributed to the subhighway matching section, and the latch clock used for the multiplexing and demultiplexing functions can be monitored to accommodate 2K capacity.
