Abstract
A circuit arrangement for telecommunication, in particular for telephone switching systems that use tdm connection and low pass filters in the lines connected in division of space connected to the multiplex lines, characterized in this because the low pass filters (tpl) associated to the transmission channels (k1 to k32) and the subscriber line circuits (tas) are connected to each other through a switching grid operating in time division multiplex (tkf), in which connections are made at the scanning frequency (f2) which is substantially higher than the scanning frequency (f1) of the multiplex lines (ml), at least 1.5 times that scanning frequency.
