Abstract
Described is the regeneration of dial pulses in the signalling system CCITT type B. The dial pulses are regenerated by a combined regeneration process comprising a reduced process with two sampling instants (10 ms, 30 ms) and an inverse process with four (anisochronous) sampling instants (10 ms, 30 ms, 52 ms, 72 ms). The reduced process is started by the stop-start transition at the beginning of the first of a series of dial pulses and the inverse process by the start-stop transition which occurs at the end of the series of dial pulses.
