METHOD AND DEVICE FOR ADDRESS DRIVE TYPE TIME DIVISION EXCHANGE AND ITS EXCHANGE MODULE

摘要

PURPOSE:To contrive the simplification of the exchange connection control by comparing a time slot number added at every slot information of an input time division information string with a time slot number string of an output time division information string moved on a time base in opposite direction with the unit of time slot time and applying required exchange processing when the both are coincident. CONSTITUTION:An incoming side shift system 2 adds a time slot number at every time slot to input time division information under the control of an exchange control means 6 in response to the occurrence of an exchange call to shift each inputted information in a 1st direction. An outgoing shift system 4 shifts the output time division information string assigned with the time slot number at every time slot under the control of the exchange control means 6 in an opposite direction to the 1st direction at every time slot. A comparator 8 always checks whether or not coincidence takes place between the time slot number being shifted by the incoming shift system 2 and the time slot number being shifted in the outgoing shift system 4 without intermission and allows a gate circuit 10 to fetch the input information of the incoming shift system 2 in the time slot to the outgoing shift system 4 when they are coincident.
