RADIO AND TV INTERFERENCE
The Multi-Rate Ethernet Extender generates and uses radio frequency energy,
and if not installed and used properly-that is, in strict accordance with the manu-
facturer’s instructions-may cause interference to radio and television reception.
The Multi-Rate Ethernet Extender has been tested and found to comply with the
limits for a Class A computing device in accordance with specifications in Sub-
part B of Part 15 of FCC rules, which are designed to provide reasonable protec-
tion from such interference in a commercial installation. However, there is no
guarantee that interference will not occur in a particular installation. If the Ether-
net Extender does cause interference to radio or television reception, which can
be determined by disconnecting the unit, the user is encouraged to try to correct
the interference by one or more of the following measures: moving the comput-
ing equipment away from the receiver, re-orienting the receiving antenna and/or
plugging the receiving equipment into a different AC outlet (such that the com-
puting equipment and receiver are on different branches).

1.2 Description
The Multi-Rate Ethernet Extender/L (Local) and Multi-Rate Ethernet Extender/R
(Remote) provide high speed LAN connections between peered Ethernet LANs,
remote PC’s, or any other network enabled 10/100Base-T device.
Operating in pairs, a Multi-Rate Ethernet Extender/L located at one end of the
LAN extension and an Multi-Rate Ethernet Extender/R at the other end, these
units can automatically forward LAN broadcasts, multicasts, and frames across a
2-wire voice-grade twisted-pair link. The data is passed transparently (unmodi-
fied) through the Ethernet Extenders. The Ethernet Extenders automatically add

MULTI-RATE ETHERNET EXTENDER

and delete MAC addresses, only passing packets across the link that are meant
for the remote peered LAN.
Figure 1. Typical application
The Local and Remote Multi-Rate Ethernet Extenders work together to create a
transparent extension between two peered Ethernet LANs. Figure 1 shows a typi-
cal point-to-point application.

Note If asymmetric transmission or line rates other than 12.5 Mbps are
required, refer to section 3., “Configuration” on page 14.
2.1 Installing the LB200A
Do the following:
1. Connect the line interface between the units (refer to section 2.2, “Connect-
ing 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 2.3, “Connecting the
10/100Base-T Ethernet Interface” on page 11).
3.

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 Ethernet Extender interfaces.
The Ethernet Extender units work in pairs. One of the units must be a Local (L),
and the other unit must be a Remote (R). 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 powered on or by
having its power reset.
1. To function properly, the two Ethernet Extenders 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 equipment are not acceptable.
2. The Ethernet Extender is equipped with two interface jacks that can be used
on the LINK interface, an RJ-45 or a terminal block. These LINK interfaces
are a two-wire interface. Observe the signal/pin relationships on the LINK
interface jacks.
The RJ-45 connector on the Ethernet Extender’s twisted pair interface is polarity
insensitive and is wired for a two-wire interface. The signal/pin relationship is
shown in Figure 3.

2.3 Connecting the 10/100Base-T Ethernet Interface
The shielded RJ-45 port labeled Ethernet is the 10/100Base-T interface.This port
is designed to connect directly to a 10/100Base-T network. Figure 5 shows the
signal/pin relationships on this interface.You may connect this port to another
Ethernet device via a Type 4 or Type 5 cable that is up to 328 ft. (100 m) long.

The Ethernet Extender 10/100Base-T interface is configured as DTE (Data Ter-
minal Equipment), just like a 10/100Base-T network interface card in a PC.
Therefore, it “expects” to connect to a 10/100Base-T Hub using a straight-
through RJ-45 cable. Figure 6 diagrams the cable wiring for connecting the
Ethernet Extender to a 10/100Base-T hub.

The Ethernet Extender 10/100Base-T interface is configured as DTE (Data Ter-
minal Equipment). If you wish to connect the Ethernet Extender to another DTE
devices such as 10/100Base-T network interface card in a PC (or Ethernet
Extenders in a back-to-back arrangement), you must construct a 10/100Base-T
crossover cable as shown in Figure 7.
Figure 7. 10/100Base-T crossover cable
2.4 Connecting Power
An externalAC or DC power supply is available separately. This connection is
made via the barrel jack on the rear panel of the Ethernet Extender. No configura-
tion is necessary for the power supply (SeeAppendix B for domestic and interna-
tional power supply and cord options).
DC power (supplied via the power supply jack to the Ethernet Extender) must
meet the following requirements; DC power supplied must be regulated +5VDC

•
Connect the equipment to a 5 VDC supply source that is electrically isolated
from the AC source. The 5 VDC source must be reliably connected to earth.
• An approved external SELV source—rated a maximum of 5 VDC, 2 A—that
incorporates a disconnect device must be used and positioned within easy
reach of the operator’s position.
The Ethernet Extender does not have a power switch, so it powers up as soon as it
is plugged in.
WARNING
There are no user-serviceable parts in the LB200A
modem. Fuse replacement should only be per-
formed by qualified service personnel. Contact

3.1 Configuring DIP Switch S1
DIP switch S1 is where you configure the Link line rate, symmetric or asymmetric,
Ethernet full auto negotiation capability (100Base-T full or half duplex, 10Base-T
full or half duplex) or limited auto sense (only 100Base-T half duplex, 10Base-T
full or half duplex).
3.1.1 S WITCH S1-1: E THERNET A UTO S ENSE
Use switch S1-1 to configure the unit for full auto sense capability or limited auto
sense capability. Full Auto sense capability consists of standard Ethernet Auto
sensing (100BaseT full duplex, 100BaseT half duplex, 10BaseT full duplex, and
10BaseT half duplex). Limited Auto sensing capability consists on only auto sens-
ing for 100BaseT half duplex, 10BaseT full duplex, and 10BaseT half duplex.The
limited auto negotiation feature is used when an Ethernet device does not comply
with IEEE 802.3x (back pressure flow control) at 100M full duplex.

Link (Active Green) Solid green (ON) to indicate that the
end-to-end VDSL link between the Ethernet
Extenders is established.The LINK LED is OFF
when the link is down.
QOL (ActiveYellow) FlashesYELLOW to indicate the proces-
sor is correcting an error in the data thus preventing the
transmission of corrupted data to the Ethernet port.The
more error corrections, the more often the LED blinks.If
the light remains lit continuously, it means that the line is
noisy—although the data at the Ethernet port remains
uncorrupted. Further impairment of the line however,
risks having the line fail, as indicated by the green Link
LED extinguishing.
