ABSTRACT:
A fixed wireless access system includes a base station for bidirectional communication with a switching center, a private branch exchange (PBX) for bidirectional communication with a plurality of user stations, and a wireless trunk interface (WTI). The WTI communicates with the base station over a bidirectional wireless air link, and with the PBX over a bidirectional trunk line. Since a wireless link is established between a dual radio unit (DRU) at the base station and a transceiver at the WTI, the slots normally allocated to the directory number of the called and calling parties in the current air interface, must be used to identify the transceiver involved in the exchange of information. Therefore, the DN of the called station behind the PBX is transmitted to the WTI using other fields of the air interface, and presented to PBX in a format acceptable for establishing a correct connection (DID service). Similarly, the DN of the calling station behind the PBX, is transmitted to base station and presented to switching center using a format acceptable for use by the switching center (AIOD service).
