APPARATUS AND METHOD FOR COMPENSATING TIMING DIFFERENCE OF SEVERAL DIFFERENT DIGITAL LINKS BETWEEN PRIVATE BRANCH EXCHANGE AND BASE STATION IN WIRELESS PRIVATE BRANCH EXCHANGE SYSTEM

摘要

PURPOSE: An apparatus and a method for compensating a timing difference between inter-different digital links between a private exchange and a base station in a wireless private exchange system are provided to easily increase a channel of a base station by compensating the timing difference generated in case of interlocking two digital links or more in a wired interval between the wireless private exchange and the base station. CONSTITUTION: A voice channel stream unifying unit has a shift register(100) for converting a voice channel stream of a link, which is supposed to be changed according to a reference frame among inter-different digital links from serial data, to parallel data according to the first control signal. The voice channel stream unifying unit has a shift register(200) for converting the voice channel stream from the parallel data to the serial data according to the second control signal and outputting the voice channel stream to be changed according to the reference frame. A voice channel stream redistributing unit has a shift register(300) for converting the voice channel stream from the serial data to the parallel data according to the third control signal. The voice channel stream redistributing unit has a shift register(400) for converting the voice channel stream from the parallel data to the serial data according to the fourth control signal and outputting the voice channel stream to be changed according to each frame of the inter-different digital links.
