RECEIVING SYSTEM FOR TIME SHARING CHANNEL CONTROL INFORMATION

摘要

PURPOSE:To reduce the number of control informaton receiving circuits and simplifying an interface circuit with a central processing unit by using the control information receiving circuits in common to plural input call highways. CONSTITUTION:Plural input call highways 1 including a few time slots in a frame are multiplexed with output call highways 3 with many time slots in a frame and control information receiving circuits R are connected to the output call highways 3 to use the control information receiving circuits R in common to plural input call highways 1. In order to multiplex plural input call highways 1 with the output call highways 3, a series/parallel converter SP, a latch L and a multiplexer MPX are installed.
