This invention involves the implementation of a mobile, automatic range extension network for a communication system, such as may be used by a field army. Range extension techniques related to this invention are those necessary for the acceptance and routing of calls within the system, with the placement of such calls being accomplished in accordance with a novel automatic sequential search technique. The routing information required for conducting this search is derived from normal equipment operation, and significantly, range extension calls are placed without the aid of area codes. Automaticity of operation permits the range extension equipment to adapt to its geographical environment, and automatically up-dates its routing information to take into consideration physical changes, thus permitting frequent movements of centrals to take place within the telephone system without disrupting communications.
