Abstract
In a time division switching system, a reference pulse generator generates constant reference timing pulses for operating a switch. First and second variable phase pulse generators generate first and second trains of variable phase timing pulses. Data signals on a first group of input lines are multiplexed in response to the timing pulses of the first train to produce a first time division multiplexed (TDM) signal and data signals on a second group of the input lines are multiplexed in response to the timing pulses of the second train to produce a second TDM signal. The TDM signals are carried on first and second highways respectively to the space switch. The first and second variable phase pulse generators are controlled so that the timing of each of the first and second TDM signals coincides in the space switch with the reference timing pulse.
