Abstract: A fixed wireless communication system (100) is a hybrid of a fixed wire-line telephone system and a conventional cellular radio system. In particular, this fixed wireless telephone system (100) provides an instant communication link between a user's fixed wireless terminal (101) and a wire line communication system (105), allowing a user to dial another user's number, as well as, receive call progress tones such as the dial tone. This link is established by detecting (403) an off hook signal at the communication device, transmitting (405) a call set up request with a “ghost” telephone number over the conventional cellular system, and recognizing (411) the “ghost” telephone number, requesting (413), responsive thereto, an audio link on the wire line communication system (105), and linking (415) the audio link on the wire line communication system with the first communication device over the conventional cellular radio communication system.

Abstract: An Internet Protocol telephone system and method uses a telephone (26) to place and receive voice over Internet Protocol (VoIP)-based telephone calls and public switched telephone network (PSTN)-based telephone calls. An off-hook condition with the telephone (26) is detected and a sequence of signals generated by the telephone (26) is received. At least a first signal generated by the telephone (26) is buffered while the system attempts to detect a predetermined signal that signifies a VoIP-based call. Upon detection of the predetermined signal, the system intercepts subsequent signals in the sequence, absent the at least first signal that was buffered, and places the VoIP-based call via an internet (12). Otherwise, the system places the PSTN-based call via a PSTN (16).

Abstract: To facilitate the reversion of a communication to tandem operation (200), a first transcoder (20), having previously changed back to tandem operation (206), inverts bits (208) of a double-encoded frame format that correspond to synchronisation bits in a non-tandem, single-encoded frame format to generate errors, in relation to the synchronisation bits, at a second transcoder (34). Upon detection (210) of a predetermined number of errors in the synchronisation bits during a predetermined time, the second transcoder (34) reverts to tandem operation, as shown in the flow diagram of FIG. 2.

Abstract: An apparatus and a method for receiving and transmitting information from an array of adaptive antenna elements, wherein a predictive filter supplies an estimate of received signal samples likely to be received in a burst immediately preceding a transmission. Combination of this estimate with received signal samples obtained from actual (historically received) signals, received over a predetermined number of frames, yield estimates of optimum beamforming coefficients for application to data for transmission from an adaptive array of antenna elements. As such, available processing time for obtaining the beamforming coefficients is increased.
