Abstract

In an existing time division exchange system the known switching network and connection units are retained, but the control of these units is taken over by a pair of new control units which replace a collection of previous units such as multi-registers, markers, translators, call charging devices etc. The new control units each comprise a multi-register portion and a dialogue portion with the multi-register portion governing the setting up and the clearing down of traffic while the dialogue portion performs most of the communication between the multi-register portion and the rest of the exchange equipment. The control units are microprogrammed machines under the control of a 'macroprogram' assembled using the conventional computer techniques. The control units are connected to a data processing center via a monitoring unit.
