Digital wireless interface for a base station for establishing communication between a plurality of digital radio channels and a plurality of digital wireline circuits
First Claim
1. A base station in a cellular network for establishing communication between one or more digital radio channels and one or more digital wireline circuits, each wireline circuit consisting of one or more bearer channels and a data channel carrying signaling information, comprising:
- an r.f. unit for transmitting and receiving signals over said digital radio channels;
a digital interface unit (DNIC) connected to each wireline circuit for converting incoming channels from said wireline circuits to serial bus format, and for converting outgoing channels over said wireline circuits to an appropriate wireline format and;
a common serial bus connected to a plurality of said digital interface units, said bearer and data channels being assigned to appropriate channels on said serial bus;
a microprocessor connected to said serial bus for extracting the data channels and interpreting the signaling information to determine whether it is destined for the base station, said microprocessor responding to digital messages destined for the base station and passing through messages destined for the r.f. unit or wireline circuits; and
a multiplexer-demultiplexer unit for interfacing said microprocessor and said serial bus to said r.f. unit.

Abstract
An apparatus for establishing communication between one or more digital radio channels and one or more digital wireline signals over the digital radio channels, comprising an r.f. unit for transmitting and receiving circuits, a digital interface unit connected to each wireline circuit, a unit for separating incoming signals into bearer channels and signaling information, and a unit for recombining the outgoing bearer channels and signaling information into the appropriate format for transmission over the outgoing medium.
