Patent ID: 7020488

Claim:
A communications unit comprising: a) a first wireless transceiver port operable to communicate with a first wireless transceiver operable to conduct wireless communications with a wireless base station; b) a first expansion interface in communication with said first wireless transceiver port, having a bus interface operable to communicate with expansion interfaces of respective communications unit on respective communication channels associated with respective said communications units, to permit any of said communications units communicate with said wireless base station through the first wireless transceiver; c) a processor circuit programmed to effect communications between said first wireless transceiver port and said first expansion interface; d) a first communications appliance interface, said processor circuit being operable to effect communications between said first wireless transceiver port, said first expansion interface and said communications appliance interface; e) said processor circuit being programmed to receive dialed digits from said communications appliance interface and communicate said dialed digits to said first wireless transceiver port to cause a transceiver in communication with said first wireless transceiver port to dial said dialed digits on a wireless network; and said processor circuit being programmed to communicate said dialed digits to said first wireless transceiver in response to a change in the rate at which dialed digits are received at said communications appliance interface.
