CONTROLLING METHOD OF SUBSCRIBER CIRCUIT FOR TIME DIVISION SWITCHBOARD

摘要

PURPOSE:To realize the control through a common control circuit part for plural receiving circuits of multi-frame constitutions, by distributing the receiving circuits having functions common with each other at the same control bit position and then those receiving circuits having their proper functions at their corresponding bit positions respectively. CONSTITUTION:A control circuit part 1 of a subscriber circuit reads out sequentially the data written to a memory 10 by an internal counter and feeds them to a multiplex separating circuit 11. The circuit 11 performs the multiplex separation and a high-speed conversion for the control data given from an internal highway 4 and sends these data to subscriber circuits 20-2m with a 3-multi- frame constitution. The receiving circuits 200-20m detect the multi-frame patterns and discriminate the control data on their own circuits. In this case, the common function ABCJKMNQR is set at the same bit position, and functions DEFGPSTU and HL are set at their corresponding bit positions respectively in terms of the contents of each bit of distributing highways 50 and 5m which are connected to circuit 200 and 20m respectively.
