Operating in pairs, one Model 2168B is configured as the (L) Local unit located at one end of the LAN extension and the other Model 2168B is configured as the (R) Remote unit at the other end. The Model 2168B 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 2168Bs. The 2168Bs automatically add and delete MAC addresses, only passing packets across the CopperLINK link that are meant for the remote peered LAN.
