Introduction to ETHX-DS3-1-LT and ETHX-DS3-2-LT
Zhone's ETHX-DS3-1-LT and ETHX-DS3-2-LT are loop bonding Ethernet extenders
that provide up to 45 Mbps (ETHX-DS3-1-LT) or 90Mbps (ETHX-DS3-2-LT) of
symmetrical bandwidth using DS3 lines for transport.
The ETHX-DS3-1-LT features one DS3 port, and the ETHX-DS3-2-LT has two DS3
ports, each capable of up to 45 Mbps bandwidth. One or two ports may be used to
deliver Ethernet connections over DS3 facilities of any given length. Zhone's loop
bonded technology provides automatic load balancing and fail-over for optimum
redundancy and data throughput. In addition the ETHX-DS3-1-LT and ETHX-DS3-2-LT
support industry standard C-Bit Parity DS3 transport facilities, ensuring maximum
distance and flexibility.
The ETHX-DS3-1-LT and ETHX-DS3-2-LT can be connected in any combination so
long as every connection pairs a provider and a subscriber unit.
ETHX-DS3-x-LT units are shipped from the factory configured as provider units. This
configuration can be changed via web management. If you wish to connect a pair of
new units in a point to point network configuration, one of the units must be re-
configured to the subscriber mode. See the “Web Interface” section of this document
for the procedure to accomplish this.
Provider and Subscriber Defaults
The following table highlights the differences between provider and subscriber units.

Powering Up the Network Extender
The DC power terminal block on the network extender has five terminals: two positive,
two negative, and one with no connection. Only one positive terminal and one negative
terminal pair need be connected for operational purposes. The second positive and
negative terminal pair may be connected to a backup DC power supply for redundancy.
There is also a system ground terminal on the back panel above the power connector.
Connect this terminal to a reliable source of ground. The ground terminal must always
be connected regardless of the powering connections. DO NOT OPERATE THE
NETWORK EXTENDER WITHOUT A GROUND CONNECTION.
Procedure
Ground Connection
1. Connect a copper wire of at least 18 AWG from a ground source to the ground lug
on the back of the case. In Telco central office installations, the ground source
must be a Common Bonding Network (CB-N)
2The ampacity of the ground conductor shall be equal to or greater than the
ampacity of the conductor connected to the DC power connection’s DC return.
3Strip the end of the ground wire. The bare stripped ends of the ground conductor
must be coated with an anti oxidation compound before crimp connections are
made to connector terminals. Crimp a connector, of a suitable size to fit the ground
lug on the chassis, on to the prepared wire end. Use only listed connection
terminals on the ground wire.
4 The ground lug on the unit has two nuts with a star washer between them.
Remove the outer nut and star washer, put the ground connector (prepared in step
3 above) over the ground stud on the chassis. Replace the star washer on the
stud, then the nut. Tighten the nut so that the ground connection is secure and will
not rotate.
Power Connection – DC Power
1. Loosen all screws at the top of the power terminal strip.
2. Insert your –48 VDC lead into the negative (–) terminal of a terminal pair. Tighten
the screw for that terminal.
3. Insert your 48 VDC return lead into the positive (+) terminal of the same terminal
pair as in Step 2. Tighten the screw for that terminal.
4. Repeat Step 2 and Step 3 for the free pair of power terminals if you have a
redundant power supply.
5 Plug the power terminal strip into the power connector on the back of the unit.
6. Verify that the Power LED on the front of the network extender is illuminated.

7
Power Connection – AC Power
1. The AC power supply is shipped with the power terminal strip already attached.
No AC power supply other than the one supplied with the ETHX-DS3-x-LT is approved
for use in powering the unit. Using any other AC power supply could cause the unit to
be non-compliant to emissions and safety regulations.
2 Plug the power terminal strip into the power connector on the back of the unit.
3 Plug the AC power cord into the AC power supply and into a compatible AC outlet.
4. Verify that the Power LED on the front of the network extender is illuminated.
ETHX-DS3-2-LT

8
Connecting the DS3 Lines
The primary feature of the network extender is loop bonding capability, although both
the provider and subscriber units are able to function with a single DS3 connection.
Loop Bonded Connection
Using two DS3 lines for one network connection (loop bonding) multiplies the speed
and data passing capability of the network extender. Two DS3 lines also act as a
backup should one of the lines become disabled.
A network extender can only establish loop bonded connections with other Zhone
equipment with the loop bonding feature.
Procedure
1. Plug the DS3 cables into the DS3 BNC 75 ohm connectors on the back of the
network extender. Each DS3 connection requires two coax cables; one for transmit
(Tx) and one for receive (Rx). Either port can be connected first.

2. Verify all connections: the DS3 LINK/ALARM LEDs on the front of the network
extender will pulse green to indicate the connections are established and
operational.
Single DS3 Connection
A single line connection can be established between a single port subscriber unit and
either a single port or dual port ETHX-DS3-x-LT provider unit. Likewise, a single line
connection can also be established between a single port provider unit and either a
single port or dual port ETHX-DS3-x-LT subscriber units.
Procedure
1. Plug two coax cables, one for transmit (Tx) and one for receive (Rx), into the DS3
BNC 75 ohm ports on the back of the network extender.
2. Verify the connection: the DS3 LINK/ALARM LED on the front of the network
extender will pulse green to indicate the connection is established and operational.
Connecting the Ethernet Lines
The 10/100BaseT Ethernet ports can auto-negotiate speed and duplex mode in
accordance with the remote equipment to which it is connected, or Ethernet speed and
duplex mode configurations can be configured using web management. (See Web
Interface on page 12.) For the best connection results, the remote devices (PCs, hubs,
or switches) should be set to auto-negotiate speed and duplex mode.
Procedure
1. Plug the Ethernet cable into one of the 10/100 ETHERNET ports on the back of
the network extender. A straight-through cable can be used for all applications.
2. Verify the connection: solid green illumination of the corresponding
10/100 ETHERNET Connection LINK/ACT (Link/Activity) LED on the front of the
network extender indicates a connection has been established. If the Ethernet
LINK/ACT LED is illuminated but not the Ethernet 100 LED, then a 10 Mbps
connection has been established. If the Ethernet LINK/ACT and 100 LEDs are
both illuminated, then a 100 Mbps connection has been established.

Web Interface
The network extender’s integral web management lets you configure and monitor the
network extender using a standard web browser.
To manage a Provider unit using web management, connect your PC to any Ethernet
port of the Provider unit.
By default, the Subscriber unit can be managed by the web management through its
Ethernet ports. If you wish to manage the subscriber unit via a DS3 ports, and the unit
still has the default IP address, you must first create a static ARP in your PC.
Establishing an ARP Table Entry for a Subscriber Unit
The subscriber unit’s DS3 ports will not respond to an ARP request containing the
unit’s default IP address. In order to manage the subscriber unit using web
management you must create a static ARP table entry on your PC. To build a static
ARP table entry:
Procedure
Note – This procedure is not necessary if you are connecting directly to the
Ethernet ports on either the provider or subscriber units.
1. Get the MAC address from the bottom label of the subscriber unit.
2. Open a command prompt. (Click on Start, and then Run. In the Open: window
type CMD and press Enter.) At the command line, type:
arp -s 192.168.254.251 xx-xx-xx-xx-xx-xx
where the IP address is the default address of the subscriber unit and the MAC
address is the number on the bottom label. For example: if the MAC address on
the bottom label is 00-50-ca-01-28-86, type:
arp –s 192.168.254.251 00-50-ca-01-28-86
Once the ARP table entry is configured, you can ping and manage the unit using web
management.
If you change the IP address to anything other than the default, the subscriber unit
responds to ARP requests and does not require a static ARP table entry to manage it
using web management.
For security purposes you may want to turn off inband management of the unit to
prevent a local PC from managing the unit from the Ethernet ports.

13
Web Interface System Requirements
 Web Browser – Required for running web management. Compatible web
browsers include, but are not limited to, Microsoft Internet Explorer (v4.0 or higher)
and Netscape Navigator (v4.0 or higher). web management is optimized for use
with Internet Explorer.
Use your browser's default settings when running web management. JavaScript
must be enabled.


 Screen Resolution – 1024 x 768 pixels is the minimum resolution required for all
web management views to fit within the dimensions of most monitors and laptops.
Lower screen resolutions (such as 800 x 600 pixels) may cause web management
screens to exceed the width or height of the screen. To verify screen resolution on
a Windows system:
— Right click on your desktop
— Select Properties
— Click the Settings tab
— Adjust the Screen Resolution as needed
Configuring Your Windows PC to Communicate with Web Management
To communicate with web management, your PC’s Ethernet interface must be on the
same subnet as the network extender. For example, to configure the IP address under
Windows XP:
Procedure
1. In the Windows task bar, click on the Start button, and then click on Control Panel.
2. Double-click on the Network Connections icon.
3. In the LAN or High-Speed Internet window, right-click on the icon corresponding to
your network interface card (NIC) and select Properties. (Often this icon is labeled
Local Area Connection.) The Local Area Connection dialog box is displayed with a
list of currently installed network items.
4. Ensure that the check box to the left of the item labeled Internet Protocol (TCP/IP)
is checked, and click on Properties.
5. Write down the current IP Address and Subnet Mask in the Internet Protocol
(TCP/IP) Properties dialog box. When you are done using web management, you
will need to reconfigure your PC with these values.
6. In the Internet Protocol (TCP/IP) Properties dialog box, click in the radio button
labeled “Use the following IP address” and type 192.168.254.x (where x is any
number between 3 and 250, inclusive) in the IP Address field.
7. Type 255.255.255.0 in the Subnet Mask field.
8. Click on OK twice to confirm your changes, and close the Control Panel.
9. Start your web browser. Type 192.168.254.252 (for a provider unit) or

14
192.168.254.251 (for a subscriber unit) into the Address field and press Enter. The
web server opening screen appears.

Configure Provider or Subscriber Mode
To reconfigure a unit from provider to subscriber mode, open the web management
home page as described above. Observe the designation displayed on the center right
side of graphical view of the front of the unit. It will display either the word “Provider” or
“Subscriber” indicating the current mode of the unit. To make a change, click on the
“Pro/Sub Cfg” button which is located just left of center on the graphical view of the
front of the unit. This will bring up the following screen:
Click on the button associated with the desired mode for the unit. Then click on the
submit button. Go back to the home page and confirm that the display now shows the
new mode.

17
Command Line Interface
The network extender can be managed with a Command Line Interface (CLI) through
either a direct PC to COM (Communication) Port connection or from a remote network
connection via Telnet.
CLI System Requirements
 Straight-Through 8-Pin Modular Ethernet Cable – Required for establishing a
direct connection from the COM port to a DB9 adapter.
 DB9 Female to 8-Pin Modular Male Adapter – Required for conversion of your
PC's RS232 serial port for use with the Ethernet cable.
 Terminal Emulation Program – Required for running the CLI over a direct
connection. The program must emulate a VT100 terminal.
 Telnet Client – Required for remote management with the CLI. Microsoft Windows
Operating Systems (98, 2000, NT, and XP) include a Telnet client which is run
using the Windows command prompt (cmd.exe). If you are using an operating
system other than Windows, you may need to install a Telnet client.
Connecting a PC Directly
Initial configuration using the CLI requires a direct physical connection from your PC to
the COM port of the network extender you are configuring. (However, the web interface
is recommended for subsequent configuration.)
Procedure
1. Plug a DB9 to 8-pin modular adapter into the RS232 serial port on your PC. See
DB9 to 8-Pin Modular Adapter Pin Assignments on page 21.
2. Connect one end of a straight-through Ethernet cable into the adapter plugged into
your PC, and the other end of the cable into the COM port on the face of the
network extender.
Launching the Terminal Emulation Program
Launch the terminal emulation program on your PC and configure the program
settings. Actual configurations will depend upon the program being used, though
settings should be modeled after the list below; most are standard defaults. Refer to
your terminal emulation program’s user manual for further information.

Using the CLI to Establish In band Management
Option 1:
After you have logged in, enter a question mark (?) to list the available commands.
CLI Set commands are used to establish inband management. For example:
set slot 1 ip_address 137.182.10.251
set slot 1 subnet_mask 255.255.255.0
set slot 1 default_gateway 137.182.10.10
The Subscriber unit in this example can now be managed with web management by
attaching a PC to one of the network extender’s Ethernet ports or through the DS3
ports by opening the address 137.182.10.251 in a web browser.
Option 2:
After you have logged in, enter “H” for Help, to list the available commands.
CLI commands are used to establish inband management. For example:
cd syscfg
cd mgtcfg
ipaddress 137.182.10.251
subnetmask 255.255.255.0
defaultgateway 137.182.10.10
submit
Note – It is necessary to type “submit” and hit “enter” for the settings to be enabled

19
Resetting the Network Extender to Factory Defaults
The network extender supports a reset process that may be used to delete the current
configuration and return it to the factory defaults, including the default password.
Procedure
To return the network extender to its factory default configuration:
1. The reset button is located behind a small hole on the left side of the faceplate of
the network extender. Use a straightened paper clip to gently push the button and
let it go.
2. Wait a few seconds until the DS3 Port LEDs flash green starting at Port 1 and
ending at Port 2 (on an ETHX-DS3-2-LT unit). Gently push the reset button again
within 3 seconds of port 1 or port 2 LED illumination. NVRAM is cleared, and all
configurations on the unit are set to the factory defaults.
Note – As mentioned previously, the factory default for mode is “provider”.
Therefore, if the unit was a “subscriber” unit before the reset, the mode must be
changed back to subscriber mode after the reset is complete. The process of
changing the mode is described earlier in this manual.
