First Claim
1. A method comprising:
- assigning, to each of a plurality of trunks connected to a wireless access communication unit, a plurality of subscriber identifiers, one subscriber identifier for each trunk;
establishing wireless communication between the wireless access communication unit and a base station of a cellular network;
registering at least one subscriber identifier with the base station;
receiving, at the wireless access communication unit a request to initiate a call from a user connected to one of the plurality of trunks;
setting up the call over a wireless communication link between the wireless access communication unit and the base station;
communicating between the user and the cellular network across the wireless access communication unit; and
transmitting, from the wireless access communication unit to base station, the subscriber identifier for the trunk connected to the user.

Abstract
A communication system having a wireless trunk for connecting multiple phone lines over wireless communication links to a cellular network comprises a central telephone switch, such as a private branch exchange or key system, connected through one or more trunk lines to a wireless access communication unit. The wireless access communication unit preferably comprises a separate subscriber interface for each trunk line from the central telephone switch. The wireless access communication unit collects data from each of the subscriber interfaces, formats the data into a format compatible with an over-the-air protocol, and transmits the information over one or more wireless channels to a cellular base station. The wireless access communication unit thereby connects calls received from the central telephone switch'"'"'s trunk lines over a wireless trunk to a network. A controller within the wireless access communication unit interfaces the subscriber interfaces with a radio transceiver, and assists in the conversion of data from a format suitable for wireless transmission. The controller also assists in distributing data received over the wireless trunk to the separate subscriber interfaces, and converting the data to a format suitable for communication with the central telephone switch. Calls may be selectively routed by the central telephone switch over landlines, instead, to the wireless access communication unit, thereby bypassing landlines.
