HIGH SPEED ETHERNET EXTENDER

2.2 Connecting the Twisted-Pair Line Interface
The High Speed Ethernet Extender supports communication between two peer
Ethernet LAN sites over a distance of up to 6,000 ft (1.83 km) over 24 AWG
(0.5 mm) twisted-pair wire.
Note
Actual distance and link performance may vary depending on the envi-
ronment and type/gauge of wire used.
Follow the steps below to connect the High Speed Ethernet Extender interfaces.
Note
The LB400A works in pairs. One of the units must be a L (Local), and
the other unit must be a R (Remote). It does not matter which end is the L
and which is the R. The link is always initiated by the Remote. As long as
the Local is powered on, the Remote can establish a link by being pow-
ered on or by having its power reset.
1. To function properly, the two LB400As must be connected together using
twisted-pair, unconditioned, dry, metal wire, between 19 (0.9mm) and 26
AWG (0.4mm). Leased circuits that run through signal equalization equip-
ment are not acceptable.
2. The LB400A is equipped with an RJ-45 interface jack that to be used for
the LINE interface. This LINE interface is a two-wire interface. Observe
the signal/pin relationships on the LB400A’s LINE jack.
The RJ-45 connector on the LB400A's twisted pair interface is polarity insensi-
tive and is wired for a two-wire interface. The signal/pin relationship is shown in
Figure 3.
