Description
Patton Electronics CL1212E Ethernet extenders provide high-speed LAN connections between peered Ether-
net LANs, remote PCs, or any other network-enabled 10/100Base-T device.
Operating in pairs, one CL1212E is configured as the (L) Local unit located at one end of the LAN extension
and the other CL1212E is configured as the (R) Remote unit at the other end. The CL1212E is configured as
an 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. The data is passed transparently (unmodified)
through the CL1212E. The CL1212Es automatically add and delete MAC addresses, only passing packets
across the Line link that are meant for the remote peered LAN.
