CopperLink 1214E Overview
The Patton CopperLink 1214E modems provide high-speed LAN connections between peered Ethernet
LANs, remote PCs, or any other network-enabled 10/100Base-T device.
Operating in pairs, one CL1214E is configured as the (L) Local unit located at one end of the LAN extension
and the other CL1214E is configured as the (R) Remote unit at the other end. The CL1214E is configured as
a L or R via the switch on the bottom of the unit. These units can automatically forward LAN broadcasts, mul-
ticasts, and frames across a 2-wire voice-grade twisted-pair link. The data is passed transparently (unmodified)
through the 1214Es. The 1214Es automatically add and delete MAC addresses, only passing packets across the
CopperLink link that are meant for the remote peered LAN. The CL1214E is fully compatible with the Model
2174. When using the 2174, like the CL1214E, one unit must be local, the other remote. For example, when
CL1214E is set to local, the 2174 must be set to remote.
Key Features
The CopperLink 1214E includes the following features:
•
Variable rate CopperLink extender, which is easy to configure
•
Auto-MDIX Ethernet
•
Configurable 10/100, Full/Half and Auto-Negotiating Ethernet
•
Extends up to 4x 10/100Base-TX Ethernet beyond 328-foot (100-meter) limitation over a single twisted-pair,
Cat 5e/6/7
•
Symmetric or asymmetric settings via DIP switch
•
Transparent operation
•
LED indicators for Power, Link, Ethernet Link/Activity, Remote and Local
Figure 1. Typical application
The pair of CL1214E models work together to create a transparent extension between two peered Ethernet
LANs using twisted pair (2-wire) or Cat5+. Figure 1 shows a typical point-to-point application.
