PURPOSE:To attain one switch control with a half of buffer memories by conducting twice the reading of buffer memories storing information subject to time division multiplex in the unit time. CONSTITUTION:Two buffer memories 1, 2 store a signal subject to time division multiplex and selectors 3, 4, 5 and 6 select the output and give an output to a time division multiplex line. An output highway time slot selecting signal is written in switch memories 7, 8, 9 and 10 so as to control the write/read of the buffer memories 1, 2. A time slot address signal gives an output highway time slot designation signal to the buffer memory 1 as a read address and gives a designated signal to the selectors 3, 4. The same operation is conducted to the buffer memory 2 at the same time. |
