SWITCHING CIRCUIT WITH T-SWITCHES

摘要

The circuit utilizes an interface for matching T1 link constructed of 24 channel units in an exchange utilizing T1 transmitting method. 30 Channel data (NO1-NO4) is input into corresponding time switches (SW1-SW4) and is input into a time switch (SW5) as low signal for forming 24 channel data format by 6 channel unit when 30 channel-4 channel stream data is transduced to 24 channel-5 stream data.
