This format was stillborn. A joint venture by 3 Com and Gibson. A valiant attempt was made to sell it and the writer was sent a set of evaluation boards. However it required special routers to work which was in the writer's opinion tne kiss of death for it. Unfortunately the special routers never became available but it is included here just in case someone runs across the evaluation kit. 

Instead, we stuck with Cobranet at the time as it ran on standard off the shelf ethernet routers.
