CHAPTER 2: Introduction
2. Introduction
With the SDSL Network Extender 2000, you can create a
long-distance Ethernet connection over your own
private telephone wiring using Symmetric Digital
Subscriber Line (SDSL) technology, which is far faster
than regular dialup, leased-line, or even ISDN links.
Here’s how it works: If you can run (or have already
run) telephone cabling between the sites you want to
connect, put the Extender’s Provider Unit on one end
of this cabling and its Subscriber Unit on the other, then
attach them to your Ethernet networks at each site. The
two Units will send each other all of the data going
either direction on the Ethernet bus, at speeds up to
2.32 Mbps (the data rate depends on the length of the
cabling between the Units).
All you have to do is set the DIP switch once, cable the
units, and plug them in. No configuration-—no muss,
no fuss. Just a reliable, high-speed connection that’s
always on.

3. Installation
3.1 The Complete Package
The SDSL Network Extender 2000 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.
3.2 The Installation Procedure
Take these steps to install your Extender:
1. Referring to Table 3-1 on the next page, set the
DIP switch on the Provider Unit for the maximum
data rate that the Extender can support, given how
long the cable will be between the Provider and
Subscriber Units. If you don’t know how long the
cabling is, start at the setting for the shortest
distance/highest data rate; if the units can’t link
up at that speed when you interconnect them
later, try settings for progressively higher
distances/lower data rates until the link succeeds.

NOTE
Th s table assumes 26 AWG cable. You m ght be able to
ach eve better data rates or d stances f you use cable w th
th cker w res (22 or 24 AWG).
2. Set DIP switch position #4 Down for half-duplex,
and Up for full-duplex. Set this switch for both
Provider and Subscriber Units.

12
SDSL NETWORK EXTENDER 2000
NOTE
Wh le both ends of the Ethernet connect on must have the
same duplex mode conf gurat on, partner Prov der Un ts
and Subscrber Un ts don’t have to be conf gured the same.
Duplex mode does not apply to the SDSL connect on.
In half-duplex mode, Sw tch #4 s down. Rece ve and
transm t funct ons are mutally exclus ve; data transm ss on
occurs n only one d rect on at a t me. Packet coll s ons are
not uncommon.
In full-duplex mode, Sw tch #4 s up. The Ethernet l ne can
rece ve and transm t s multaneously, prevent ng packet
coll s ons and ncreas ng aggregate bandw dth from 10
Mbps to 20 Mbps.
3. Plug the output cord of the Provider Unit’s power
supply into the barrel jack on the Unit’s rear panel.
4. Plug the power supply’s input cord into a working
AC outlet. Make sure that the Power, Link, Tx,
and Rx LEDs light up.

13
CHAPTER 3: Installation
5. Plug your SDSL cable into the RJ-45 jack marked
“SDSL” on the Unit’s rear panel. (This jack is
designed to accept either RJ-45 or RJ-11 plugs. The
SDSL cable should be 22 to 26 AWG telephone
cable with Ring and Tip on the center two pins: If
it has RJ-45 connectors, Ring should be on Pin 4
and Tip should be on Pin 5. If it uses RJ-11
connectors, Ring should be on Pin 2 and Tip
should be on Pin 3.)
6. Perform steps 3 through 5 at the other site with
your Subscriber Unit. Please note that the LED
operation described in Step 4, above, does not
apply to the Subscriber Unit. The only LED that
should light is the Power LED.
7. Once the SDSL cable is connected to both the
Provider and Subscriber Units, the Connection
LED on each Unit should begin pulsing steadily
(once per second) to indicate that the SDSL link
has been established and is operating. When the
Connection LED starts doing this, the Link, Tx,
and Rx LEDs should go dark until you plug in the
Ethernet cable and an Ethernet connection is
established.

SDSL NETWORK EXTENDER 2000
NOTES
The length and qual ty of the cabl ng between the Un ts
d rectly affects the process by wh ch they establ sh an
SDSL l nk w th each other. Depend ng on these cable
character st cs, t m ght take anywhere from one to f ve
m nutes for the Un ts to establ sh the l nk. If the cabl ng s
too long to support the data rate set on the Prov der Un t,
the Un ts w ll not be able to l nk up at all. If th s happens,
s mply set the Prov der Un t’s DIP sw tch for the next-lower
data rate and the Un ts w ll automat cally try to l nk aga n.
Whenever an Extender Un t boots up w thout an SDSL
connect on, ts L nk, Tx, and Rx LEDs w ll be stead ly l t unt l
the SDSL connect on s establ shed or the Un t s powered
down. (These LEDs won’t l ght back up, however, f an
SDSL connect on s lost after hav ng been establ shed.)
When a Prov der Un t loses the SDSL connect on, t w ll
drop ts Ethernet l nk s gnal (no matter what state the L nk
LED s n!) so that, f the attached Ethernet dev ce s
capable of generat ng SNMP traps or other remote alerts,
your network-adm n strat on team can be not f ed that the
l nk has gone down.
8. Run Ethernet cable from an Ethernet hub, router,
switch, etc., to the RJ-45 jack marked “Ethernet”
on the Provider Unit’s rear panel. (This cable
should be standard 10BASE-T cable with RX+ on
Pin 1, RX– on Pin 2, TX+ on Pin 3, and TX– on
Pin 6.) When you do this, the Provider Unit’s Link
LED should come back ON, verifying the physical
Ethernet link, and any or all of the Tx, Rx, and
Collision LEDs might begin flashing.

15
CHAPTER 4: Operation
NOTE
For most appl cat ons, a stra ght-through-p nned cable s
used to attach an Extender Un t to a DTE “dest nat on
dev ce” such as a PC, wh le a cross-p nned cable s used to
attach an Extender un t to a DCE “commun cat on dev ce”
such as a hub or router. If you’re not sure wh ch type of
cable to use w th a dev ce, consult ts manual and/or check
the p nout of ts port(s); f these aren’t ava lable or you’re
st ll not sure, call Black Box Techn cal Support.
9. Perform step 8 at the other site with your
Subscriber Unit.
Once the two Units have established both DSL and
Ethernet link at their sites, data will flow normally
between the Units, essentially creating a very long
Ethernet connection at SDSL speeds. The Extender
should now operate continuously without requiring
operator intervention.
