2.2 DESCRIPTION
The Patton Electronics CopperLink Ethernet Extenders provide high-
speed LAN connections between peered Ethernet LANs, remote PC's, or
any other network enabled 10Base-T device.
Operating in pairs, a Model 2155/L (local) located at one end of the LAN
extension and a Model 2155/R (remote) at the other end, these units can
automatically forward LAN broadcasts, multicasts, and frames across a 2-
wire voice-grade twisted-pair link. The data is passed transparently
(unmodified) through the Ethernet Extenders. They operate as learning
bridges and automatically add and delete MAC addresses; only passing
packets across the CopperLink line that are meant for the remote peered
LAN.
