DS3 PROVIDER BACKHAUL UNIT AND DS3 NETWORK EXTENDER KIT
1. Introduction
These instructions provide basic installation procedures for the DS3 Provider
Backhaul Unit, 1-Port (LRA1216A). This Backhaul Unit also serves as the Provider
Unit for the DS3 Network Extender Kit (LR0025A-KIT), which also includes a
Subscriber Unit.
The DS3 Network Extender Kit can be used to create a long-distance Ethernet
connection across a DS3 circuit. All you have to do is set the DIP switch once, cable
the units, and plug them in. No other configuration-—no muss, no fuss. Just a
reliable, high-speed connection that’s always on.
CAUTION
Excess static electricity can damage your Unit(s). Use proper staticprotection handling techniques when installing and handling this
equipment.
The DS3 Provider Backhaul Unit, 1-Port comes with a power supply and this
manual. The DS3 Network Extender Kit comes with a Provider Unit, a Subscriber
Unit, a power supply for each Unit, and this manual. (The power supplies are
identical; you can use either one with either Unit.) If you didn’t receive everything,
or if anything arrived damaged, contact Black Box right away.

CHAPTER 2: Installation
2. Installation
1. Unpack the DS3 Provider Unit and its power supply.
2. Plug the power supply into both the power source and the back of the Unit.
It doesn’t matter in which order you do this. Verify that the Unit’s Power LED
is lit.
NOTE
The Unit’s 100, Act, and Lnk LEDs will also light until the DS3 link has
been established. In addition, the Unit won’t present Ethernet Link when
the DS3 line is not operational.
3. Make sure that the Provider Unit’s configuration DIP switch is set correctly
for your application:
• Switch position #1, on the left, controls the clock source: Leave it in the
default DOWN setting for Local (internal) clock, or move it to UP for Loop
clock. (When you set the same switch on the Subscriber unit, don’t set
position #1, because the Subscriber Unit always gets its clock from the
Provider Unit.)
• Switch position #2, on the right, controls the TX line build out: Leave it in
the default DOWN setting for 0 to 255 ft. (0 to 77.7 m) or move it to UP for
255 to 450 ft. (77.7 to 137.2 m).
4. Plug your DS3 cables into the DS3 TX and RX BNC ports on the back of the
Provider Unit. Verify this connection by looking at the DS3 Lnk LED on the
front of the Unit. If it’s pulsing steadily once per second, a DS3 connection is
established and operational.
5. The Provider Unit’s Ethernet port is 10/100-Mbps auto-negotiating. We
recommend that, if possible, you set the hub, switch, PC, etc., at the other end
of the Ethernet cable to auto-negotiate as well, before you connect the cable.
Plug your Ethernet cable into the Fast Ethernet RJ-45 port on the back of
the Provider Unit. Verify this connection by looking at the Fast Ethernet Lnk
LED on the Unit’s front panel. If it’s steadily lit, an Ethernet connection has
been established. Also check the 100 LED: If it’s lit, the link is operating at
100 Mbps; if it’s dark, the link is operating at 10 Mbps.

NOTE
For most applications, use a straight-through Ethernet cable when
plugging the Provider Unit into a PC, or a crossover cable when
plugging into a hub or a switch. Verify the pinout of the Ethernet device
to which you are connecting the Provider Unit in order to determine
which type of cable is required.
6. LR0025A-KIT only: Repeat steps 1 through 5 for the Subscriber Unit. Its
controls, indicators, and connectors work the same way as the Provider Unit’s,
except that it gets its clock source settings from the Provider Unit, so you
don’t need to set DIP-switch position 1.
Once the Provider Unit and a Subscriber Unit have established both DS3 and
Ethernet links on both sides of the connection, normal data communication will
flow through the Units. This will provide a very long Ethernet connection at DS3
or fractional DS3 speeds.

CHAPTER 3: Operation
3. Operation
While the Provider and Subscriber Units are plugged in and receiving power, they
will operate continuously. Each Unit’s front-panel LEDs (which are also described
on its bottom label) will show you how it’s operating:
NOTE
When a Provider or Subscriber Unit is in Red, Yellow, or Blue Alarm, its
Ethernet link will be disabled and the Fast Ethernet LEDs (100, Act, and
Lnk) will be steadily lit.
• DS3 Lnk LED (green):
– If it’s flashing, the DS3 connection has been established and traffic is flowing
on the link.
– If it’s steadily lit, the DS3 connection has been established but no traffic is
currently flowing.
– If it’s dark, Red Alarm: The incoming DS3 connection has been lost and no
data is being received. If the outgoing connection from the Unit has also
been lost, the Unit at the other end will also be in Red Alarm.
• DS3 Alm LED (amber):
– If it’s dark, the DS3 connection is operating normally, unless the DS3 Lnk
LED is also dark, in which case a Red Alarm is occurring.
– If it’s steadily lit, Yellow Alarm: The outgoing DS3 connection has been lost
and no data is being transmitted. This means that the Unit at the other end
has lost incoming connection and is in Red Alarm.
– If it’s blinking once per second, Blue Alarm: An indirect connection has been
lost and the Unit might not be receiving data. This means that the Unit at
the other end has lost a connection with an intermediate device and is in
Red or Yellow Alarm.
• Power LED (green):
– If it’s steadily lit, the Unit is powered and operating.
– If it’s dark, and all other LEDs are also dark, the Unit isn’t receiving any
power or isn’t receiving enough power to operate. If any other LEDs are lit,
the Power LED is probably defective.

DS3 PROVIDER BACKHAUL UNIT AND DS3 NETWORK EXTENDER KIT
• Fast Ethernet 100 and Lnk LEDs (both green):
– If they’re both steadily lit, a 100-Mbps Fast Ethernet connection has been
established, unless the Act LED is also steadily lit and the DS3 Lnk LED is
dark, in which case a DS3 alarm is occurring.
– If Lnk is steadily lit and 100 is dark, a 10-Mbps Fast Ethernet connection has
been established.
– If they’re both dark, the Ethernet connection is down or has been lost.
• Fast Ethernet Act LED (amber):
– If it’s flashing, traffic is flowing normally, indicating typical Ethernet activity.
– If it’s steadily lit, traffic is very heavy, unless the other Fast Ethernet LEDs are
also lit and the DS3 Lnk LED is dark, in which case a DS3 alarm is occurring.
– If it’s dark, there is no traffic flow. This means that the Ethernet connection
is either down, lost, or not being used.
