Abstract
A data shift register receives and stores each time sample (digital word) carried by an inbound channel. A selector chooses for each time slot either the input digital word received during the same time slot or the digital word stored in the shift register during the previous time slot. This selected digital word is transmitted on an input channel to a concentrator. The selector is controlled by data stored in a control shift register which causes the selector to make its selection.
