    摘要： In a digital summing process that sums non-linear digital signals by converting them to linear signals, computing their two's complement, summing the two's complements together and converting the resultant into a non-linear resultant, the fidelity of the summing process may be verified in the following manner. When only one non-linear digital signal is being summed, an algorithm determines whether the one non-linear digital signal being summed is equivalent to a predetermined value which, when passed through the summing process, will yield a different value than the one inputted. If the algorithm determines that the one non-linear digital signal is equivalent to a predetermined value, it sets a flag which indicates that the resultant over written with the predetermined value. Once the resultant is overwritten with the predetermined value, the flag is reset.

    摘要： The present invention discloses a communication system network that comprises a plurality of communication systems and a processing multiplexer. The communication systems, which may be either conventional communication systems and/or trunked communication systems, transmit digitized audio signals and communication system data to the processing multiplexer. Based on signal destination data, which is part of the communication system data, the processing multiplexer processes the digitized signals and routes the resultant signals to the appropriate signal destinations of the communication systems.

    摘要： Listening capacity of a signal destination is augmented through the provision of a master switching center (207) and a slave switching center (209) linked via a dedicated communication port (203). Under direction of the master switching center (207), the slave switching center (209) sums communication system data signals received from shared communication ports (201) and presents the resulting summed communication data to the dedicated communication port (203). The master switching center (207) presents the summed communication data, received via the dedicated communication port (203), to the signal destination, thus augmenting listening capacity of the signal destination.
