Abstract: A base transceiver station (BTS) in a cellular communication system having a base station controller (BSC) and a mobile services switching center (MSC). The BSC is configured for facilitating communication between the BSC and a plurality of mobile stations (MS's). The communication with the plurality of the MS's is accomplished via radio frequency (RF) medium. The BTS includes a first interface circuit for coupling the BTS with the BSC. The BTS further includes a processor coupled to the first interface circuit for processing first digital data received from the BSC to form second digital data. There is further included a first central transceiver (CTRX) circuit coupled to the processor. The first CTRX circuit is co-resident with the processor and the first interface circuit. The BTS further includes a first remote transceiver (RTRX) circuit coupled to the first CTRX circuit.

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.
