Abstract
A telecommunication bridge system uses synchronized arbitration in a portion of a frame of a Radio Frequency (RF) subsystem and is transparent to Ethernet layer protocols and Ethernet-type packets in order to increase bandwidth utilization and effectively extend Ethernet networks to metropolitan-area-wide application. The telecommunication bridge system comprises an enhanced Ethernet network interface subsystem coupled to a conventional Ethernet medium and a control subsystem including an RF modem, in turn coupled to a frame synchronized RF medium in a metropolitan-sized network. On one side the control subsystem emulates all Ethernet layer protocols and on the other side conducts a prioritized arbitration scheme during only a portion of a time division multiplexed frame, the remainder of the frame for carrying a payload of unmodified packets to other bridges. Included in the controller subsystem is a two-way Manchester/NRZ Code converter, its own intelligence and packet buffering using a microprocessor and random access memory.
