Abstract

A digital port comprising a passive bus and, at least, the registration and call transfer features associated with a switch to provide cellular wireless capability. The passive bus allows a base station to be connected to the channel and thereby interface a plurality of wireless terminals to the switch. While only some of the wireless terminals in the neighborhood of a base station can be active concurrently (as is the case in all wireless systems) by way of a digital communication channel that is included in the passive bus, the switch can register and, hence, keep track of, a larger number of wireless terminals that are present in the base station's neighborhood. The passive bus also includes at least one circuit switched channel to allow communication with one or more wired or wireless terminals.
