Private telecommunications switching systems with several radio base stations are known. In private telecommunications switching systems based on the DECT (digitial enhanced cordless telephone) standard, each base station serves one cell. For an unambiguous association between the DECT system and the subscriber terminals, the base stations send out an access rights identifier (ARI) which can only be received and decoded correctly by authorized subscriber terminals. Since 8 bytes are reserved in the identifier for encoding the base-station numbers, a maximum of 256 base stations can be connected to a conventional DECT system. To be able to connect a substantially greater number of base stations, ideally an unlimited number, a private telecommunications switching system (TK) is proposed in which a first subset of base stations sends out a first identifier (ARI1), and in which at least a second subset of base stations sends out a second identifier (ARI2). The identifiers are received by the subscriber terminals (MS) to determine which subset of base stations serves the area in which the respective subscriber terminal currently is.
