Abstract

An installation is described for establishing a connection between private branch exchanges (PABX), each of which has a base station allocated within a determined geographic area (GA), where the base station provides a determined number of utilization channels served by telecommunication, through which mobile cordless terminals communicate with the base station, and thereby with the branch exchange, throughout the geographic area. The base station (BS.sub.2) of a second branch exchange (PABX.sub.2) is located within the geographic area (GA) of a base station (BS.sub.1) of a first branch exchange (PABX.sub.1), and a wireless cross linkage is established by the two base stations (BS.sub.1, BS.sub.2) and their telecommunication (PABX.sub.1, PABX.sub.2).
