I am interested in information regarding broadband LAN.  The University
of Illinois has strung a campus wide CATV cable accessible from most of
the buildings.  Length of the cable is on the order of 10 to 20 km.

The hardware of interest would connect to an RF modem and provide some
well known interface at the computer bus, e.g., DR-11/W for DEC Unibus.
The hardware would do all of the low level network handshaking (token
passing, address recognition, CRC checks, etc.) and preferably some
of the higher levels.  As an ultimate I would like to see the TCP/IP
code, either in PROMs or downloaded from the host on system reset, 
executed by an on-board processor.

At this time I have the following list of companies making broadband
(not necessarily token passing) equipment:

Concord Data Systems
Proteon
Sytek
Ungermann-Bass

Any particular comments on their products are requested.

Please don't send requests for copies of the responses.  Any significant
replies will be summarized and posted to net.lan.
