Introduction to the ENE2044 and ENE2084
Paradyne's ENE2044 and ENE2084 are loop bonding network extenders for Paradyne's
12000 and 4000 IP Broadband Access Concentrators that provide up to 8 Mbps
(ENE2044) or 16 Mbps (ENE2084) of symmetrical bandwidth using E1 lines.
The ENE2044 features four E1 ports and the ENE2084 eight E1 ports, each capable of
up to 2.0 Mbps bandwidth. When used with any Paradyne loop bonding compatible
product, up to eight ports may be used to deliver high-speed bandwidth at any given
distance. Paradyne's loop bonded technology provides automatic load balancing and
fail-over for optimum redundancy and data throughput. In addition the ENE2044 and
ENE2084 support repeaters installed on the E1 loop, ensuring maximum distance and
flexibility.
The ENE2044 and ENE2084 can be connected to any combination of E1 uplink
interface modules, micro interface modules, and network extenders, so long as every
connection pairs a provider and a subscriber unit.

Package Contents
Unpack and Inspect the network extender. If there is any visible damage, do not attempt
to connect the device. Contact your sales or service provider.
Powering Up the Network Extender
The DC power terminal block on the network extender has five terminals: two positive,
two negative, and one ground. 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. The ground
terminal must be connected regardlessly. DO NOT OPERATE THE NETWORK
EXTENDER WITHOUT A GROUND CONNECTION.
Procedure
1. Loosen all screws at the top of the power terminal strip.
2. Insert your ground wire in the center terminal and tighten the screw.
3. Insert your positive and negative leads into the left or right + and – pair of terminals,
taking care to match polarity. Tighten the screws for those terminals.

Connecting the E1 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 E1 connection.
Loop Bonded Connection
Using multiple E1 lines for one network connection (loop bonding) multiplies the speed
and data passing capability of the network extender. Multiple E1 lines also act as a
backup should any of the lines become disabled.
A network extender can only establish loop bonded connections with other Paradyne
equipment with the loop bonding feature. See Product to Product E1 Loop Bonding
Compatibility (document number COMP-A2-GK43).
Procedure
1. Plug the E1 cables into the E1 Connections RJ45 ports on the back of the network
extender. The order of connection is not important.
2. Verify all connections: the E1 Connections Lnk/Alm LEDs on the front of the
network extender will pulse green to indicate the connections are established and
operational.

Single E1 Connection
A single line connection can be established between a subscriber unit and any
Paradyne E1 provider unit, regardless of loop bonding capability. Likewise, a single line
connection can also be established between a provider unit and any of Paradyne's E1
subscriber units, regardless of loop bonding capability.
Procedure
1. Plug the E1 cable into any of the E1 RJ45 ports on the back of the network
extender.
2. Verify the connection: the related E1 Connections Lnk/Alm LED on the front of the
network extender corresponding to the connected port 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 NMS. (See Web Interface on
page 10.) 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 Lnk/Act (Link/Activity) LED on the front of the network extender
indicates a connection has been established. If the Ethernet Lnk/Act LED is
illuminated but not the Ethernet 100 LED, then a 10 Mbps connection has been
established. If the Ethernet Lnk/Act and 100 LEDs are both illuminated, then a
100 Mbps connection has been established.

Web Interface
The network extender’s integral Network Management System (NMS) lets you configure
and monitor the network extender using a standard web browser.
To manage a Provider unit using NMS, connect your PC to any Ethernet port of the
Provider unit.
By default, the Subscriber unit can be managed by NMS through an active E1 line from
the Provider side of the network. To enable inband management and configure an IP
address, you must use the Command Line Interface. (See Command Line Interface on
page 13.) After that is done, the Subscriber unit can be managed through its Ethernet
ports.
Web Interface System Requirements
„
Web Browser – Required for running NMS. Compatible web browsers include, but
are not limited to, Microsoft Internet Explorer (v4.0 or higher) and Netscape
Navigator (v4.0 or higher). NMS is optimized for use with Internet Explorer.
Use your browser's default settings when running NMS. JavaScript must be
enabled.
„
Screen Resolution – 1024 x 768 pixels is the minimum resolution required for all
NMS views to fit within the dimensions of most monitors and laptops. Lower screen
resolutions (such as 800 x 600 pixels) may cause NMS 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 NMS
To communicate with NMS, 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.
10
5. Write down the current IP Address and Subnet Mask in the Internet Protocol
(TCP/IP) Properties dialog box. When you are done using NMS, 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
192.168.254.251 (for a subscriber unit) into the Address field and press Enter. The
web server opening screen appears.
10. Click on >> Next >>. The login dialog box appears. Log in using:

Establishing an ARP Table Entry for a Subscriber Unit
Inband management is turned on by default in the subscriber unit, but the unit will not
respond to an ARP request containing the unit’s default IP address. In order to manage
the subscriber unit using NMS you must create a static ARP table entry on your PC. To
build a static ARP table entry:
Procedure
1. Get the MAC address from the bottom label of the subscriber unit.
2. Open a command prompt. (Click on Start, 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. Add 1 to the last byte of the MAC
address if you are managing the unit from any of the Ethernet ports. For example: if
the MAC address on the bottom label is 00-50-ca-01-28-86, use 00-50-ca-01-28-87
in the arp command. If the MAC address on the label is 00-50-ca-01-28-ea, use
00-50-ca-01-28-eb in the arp command.
If you are managing the subscriber unit from the E1 side of the network, you do not
have to add one to the MAC address since the WAN (E1) ports are considered to be
Out of Band.
Once the ARP table entry is configured, you can manage the unit using NMS.
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 NMS.
12
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.
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 RJ45 to RJ45 Ethernet Cable – Required for establishing a
direct connection from the COM port to a DB9 adapter.
„
DB9 Female to RJ45 Male Adapter – Required for conversion of your PC's RS232
serial port for use with the RJ45 to RJ45 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 RJ45 adapter into the RS232 serial port on your PC. See DB9 to
RJ45 Adapter Pinouts on page 16.
2. Connect one end of a straight-through RJ45 to RJ45 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.
13
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.

Password
After you have logged in, enter a question mark (?) to list the available commands.
Using the CLI to Establish Inband Management
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 NMS by attaching a PC
to one of the network extender’s Ethernet ports and opening the address
137.182.10.251 in a web browser.
