Abstract

A circuit arrangement is provided for timing the receiving section of a terrestrial interface module of the voice digital interpolation type, in a time- division transmission system via satellite comprising a plurality of stations. Counting of the standard channel number and of the overload channel number emitted by each station is carried out by means of a single counting chain CN with which is associated a memory MM capable of storing the channels which have been emitted by each station. If in the same frame a given station emits further blocks of channels, the number of channels previously stored in the memory MM is pre-loaded into the counting chain, and the counting continues from this number.
