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 2172Rs or 2172s. The 2172Rs
automatically add and delete MAC addresses, only passing packets
across the CopperLINK link that are meant for the remote peered LAN.
Figure 1.
Typical application
The pair of 2172R and 2172 models work together to create a transparent
extension between two peered Ethernet LANs. Figure 1 shows a typical
point-to-point application.
3.0 INSTALLATION
To install the 2172R Ethernet Extender, do the following:
1. Connect the line interface between the units (refer to section 3.1,
“Connecting the Twisted-Pair Line Interface” on page 9)
Note
See Figure 2 for the standalone unit’s rear panel arrangements.
2. Connect the Ethernet interface (refer to section 3.2, “Connecting the
10/100Base-T Ethernet Interface” on page 11).
3. Connect the power plug (refer to section 3.3, “Connecting Power” on
page 11).
The Interconnecting cables shall be acceptable for
external use and shall be rated for the proper applica-
tion with respect to voltage, current, anticipated tem-
perature, flammability, and mechanical serviceability.
