Abstract
A base station includes a digital signal processor, the base station operable to communicate with at least first and second wireless terminals using compressed digital signals modulated onto a radio frequency carrier, the base station further operable to communicate with an external network to facilitate a call between one or more wireless terminals and another party connected to the external network. The digital signal processor is operably connected to receive compressed signals from and provide compressed signals to the first and second wireless terminals, and further operably connected to communicate uncompressed signals with the external network. The digital signal processor is programmed to execute instructions to perform the following functions: monitor a first signal, the first signal received from the first wireless terminal; monitor a second signal, the second signal received from the second wireless terminal; monitor a network signal, the network signal received from the external network; select using predetermined criteria a priority signal, the priority signal comprising one of the first signal, the second signal and the network signal; and perform either a compression or decompression process on the priority signal and then provide the processed priority signal to at least one of the first wireless terminal, second wireless terminal and external network.
