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
This table assumes 26 AWG cable. You might be able to achieve better data rates or distances if you use cable with thicker wires (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.
11
SDSL NETWORK EXTENDER 2000
NOTE
While both ends of the Ethernet connection must have the same duplex mode configuration, partner Provider Units and Subscriber Units don’t have to be configured the same.
Duplex mode does not apply to the SDSL connection.
In half-duplex mode, Switch #4 is down. Receive and transmit functions are mutally exclusive; data transmission occurs in only one direction at a time. Packet collisions are not uncommon.
In full-duplex mode, Switch #4 is up. The Ethernet line can receive and transmit simultaneously, preventing packet collisions and increasing aggregate bandwidth 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.
12
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.
13
SDSL NETWORK EXTENDER 2000
NOTES
The length and quality of the cabling between the Units directly affects the process by which they establish an
SDSL link with each other. Depending on these cable characteristics, it might take anywhere from one to five minutes for the Units to establish the link. If the cabling is too long to support the data rate set on the Provider Unit, the Units will not be able to link up at all. If this happens, simply set the Provider Unit’s DIP switch for the next-lower data rate and the Units will automatically try to link again.
Whenever an Extender Unit boots up without an SDSL connection, its Link, Tx, and Rx LEDs will be steadily lit until the SDSL connection is established or the Unit is powered down. (These LEDs won’t light back up, however, if an
SDSL connection is lost after having been established.)
When a Provider Unit loses the SDSL connection, it will drop its Ethernet link signal (no matter what state the Link
LED is in!) so that, if the attached Ethernet device is capable of generating SNMP traps or other remote alerts, your network-administration team can be notified that the link 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.
14
CHAPTER 4: Operation
NOTE
For most applications, a straight-through-pinned cable is used to attach an Extender Unit to a DTE “destination device” such as a PC, while a cross-pinned cable is used to attach an Extender unit to a DCE “communication device” such as a hub or router. If you’re not sure which type of cable to use with a device, consult its manual and/or check the pinout of its port(s); if these aren’t available or you’re still not sure, call Black Box Technical 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.

4. Operation
While the SDSL Network Extender 2000 is operating, you can inspect the front-panel LEDs on its Units at any time for status information:
LED Meaning
Connection Pulses green once per second to show that the SDSL connection is operational and the
Unit is receiving either valid data packets or status packets from the other Unit.
Power
Collision
