The Patton Electronics Model 2173 CopperLink modems provide highspeed
LAN connections between peered Ethernet LANs, remote PC’s, or
any other network enabled 10/100Base-T device.
Operating in pairs, one Model 2173 is configured as the (L) Local unit
located at one end of the LAN extension and the other Model 2173 is configured
as the (R) Remote unit at the other end. The Model 2173 is configured
as a L or R via the switch on the bottom of the unit. 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 2173s. The 2173s automatically add and delete
MAC addresses, only passing packets across the CopperLINK link that are
meant for the remote peered LAN.
