High-speed LAN bridging is possible with the Digital Access A-115 Asynchronous
Line Driver and the Shiva TeleBridge. With these products, two LocalTalk LANs
as far apart as 3.5 miles can be bridged at speeds up to 57.6K bps. All
connections are over twisted-pair copper wiring. Installation is simple, and,
because all connections are over existing wiring, there is no high installation
cost. For more information, search the Tech Info Library under "Digital Access
