Abstract
An apparatus and method enabling private branch exchanges (PBXs) to increase their communication capacity in a cost efficient manner by communicating over a wireless interface. The wireless private branch exchange comprises a handset transceiver station (HTS) coupled to a private branch exchange (PBX) connected to a plurality of terminals. During inbound information processing the wireless communication network transmits inbound information to the wireless PBX. The inbound information transmitted by the wireless communication network is received by the HTS. The HTS decodes the inbound information, performs protocol conversion from GSM format to ISDN format and then forwards the inbound information to the PBX. The PBX then routes the inbound information to the appropriate terminal. During outbound information processing the HTS receives outbound information from the PBX. The HTS performs protocol conversion from ISDN to GSM, and encodes the outbound information. The outbound information is then transmitted by the HTS over a wireless interface to the wireless communication network. The wireless communication network then routes the outbound information to the destination external telephone network terminal. Exemplary embodiments are provided for use with the Global Systems for Mobile Communication (GSM) protocol and can be applied to other digital technologies
