Abstract

PURPOSE:To block the DC level due to residual data from interfering with the communication, by providing the time switch preventing the leakage of signal by the residual data with the channel at the outgoing side of the communication line network at non-communication. CONSTITUTION:When the data D of the time slot ti of the incoming side highway GHWb is replaced with the time slot ta of the output highway OHW, and if the address control memory AM is accessed with ti, the address data A(ta) and the data selection bit DSB are read out. The data D of ti is written in the address A(ta) of the data path memory DPM. The channel counter CTR outputs A(ta) at ta, and the data D of DPM is fed to OHW at ta. At non-communication state, the data selection bit DSB is replaced into ''0'' at the time slot ti of AM. Thus, the fixed pattern FPD is fed to OHW in place of the data in residual on DPM to prevent the leakage of residual data.
