Package Contents
Unpack and Inspect the Equipment. The following components should be included:
1 SNE2020G
1 Power supply
If there is any visible damage, do not attempt to connect the device. Contact your sales
or service provider.
Connecting to Power
Plug the power supply into the Power Adapter port on the back of the SNE2020G and
connect it to your power source. Verify that the Power LED on the front of the
SNE2020G is illuminated.

Switchpack Configuration
Configuration switches for the SHDSL ports are on the back of the SNE2020G,
numbered from left to right, 1–4.
Bandwidth: Switches 1–3 (SNE2020G-P Only)
Switches 1–3 on the SNE2020G-P provide eight bandwidth options for the two SHDSL
ports. Bandwidth for the two ports cannot be configured individually. Distance
capabilities listed in the following table assume the use of 26 American Wire Gauge
(AWG) cable. Connections made with cable of a heavier gauge will link up at greater
distances. Your SNE2020G may not link up if the cable is in poor condition or if the cable
distance is greater than a particular bandwidth will support. If link is acheived under
such conditions, traffic quality may be affected.

* Adaptive mode allows the SNE2020G-P to train up to the best possible speed
supported by the SNE2020G-P, the remote modem to which it is connected, and the
copper cable pair(s) connecting the two. The maximum reachable distance for a single
line SNE2020G-P connection in Adaptive mode is 25,400 feet (at 144 kbps).
Bandwidth cannot be configured on the SNE2020G-S. Subscriber units determine
bandwidth via communication with their partner SHDSL provider unit.

Ethernet Duplex Mode: Switch 4
The Ethernet link can be configured at either Full Duplex or Half Duplex mode. Although
both ends of the ETHERNET connection must have the same duplex mode
configuration, it is not necessary for partner providers and subscribers to be configured
the same. Duplex mode does not apply to the SHDSL link.
Half Duplex Ethernet – Receive and transmit functions are mutually exclusive. Data
transmission occurs in only one direction at a time. Packet collisions are not
unusual.
Full Duplex Ethernet – The Ethernet line can receive and transmit simultaneously,
effectively increasing aggregate bandwidth from 10 Mbps to 20 Mbps and
preventing packet collisions.

CAUTION:
If you set the SNE Provider or Subscriber unit to Full Duplex, you must also
set your connected Ethernet device to 10 Mb Full Duplex. Do not connect a
Full Duplex Ethernet port to a Half Duplex port or to an Auto-Negotiate port.
Connecting a Half Duplex port (default) to an Auto-Negotiate port will function
properly.
5
Connecting the SHDSL Lines
An SNE2020G-S must be connected via an SHDSL line to an SNE2020G-P, a Mini
DSLAM, a Micro DSLAM, or a Broadband Access Concentrator (BAC) interface module.
Neither a subscriber-to-subscriber nor a provider-to-provider connection will function.
Loop Bonded Connection
Using two SHDSL lines for one network connection (loop bonding) will yield twice the
speed of a single SHDSL connection. A second SHDSL line also provides a backup
should one of the lines become disabled.
The SHDSL equipment at both ends of a subscriber line must be loop bonding capable
in order for the SNE2020G to utilize the loop bonding feature. Refer to the SDSL Loop
Bonding Product to Product Feature Compatibility document on the Paradyne website
for a complete list of SDSL loop bonding capable products and required firmware
versions.
Procedure
To establish a loop bonding connection:
1. Plug your SHDSL cables into the SHDSL RJ45 ports (SDSL 1 and SDSL 2) on the
back of the SNE2020G. The order of connection is not important.
2. Verify both connections: the SDSL 1 and SDSL 2 LEDs on the front of the
SNE2020G will pulse green to indicate the connections are established and
operational.
Single Line Connection
Procedure
To establish a single line connection:
1. Plug your SHDSL cable into one of the two SHDSL RJ45 ports on the back of the
SNE2020G. Either port (SDSL 1 or SDSL 2) may be used.
2. Verify the connection: the SDSL LED on the front of the SNE2020G (SDSL 1 or
SDSL 2, depending upon which port was connected) will pulse green to indicate the
connection is established and operational.
Link up time between local and remote SHDSL network extenders can vary from one to
five minutes depending on the quality, gauge and distance of the copper cables. If cable
distance is greater than a particular bandwidth will support, the units may not link up or,
if they do achieve link, traffic quality may be affected.

Connecting the Ethernet Line
Plug the Ethernet cable into the Ethernet Connection RJ45 port on the back of the
SNE2020G. Verify the connection: solid illumination of the Ethernet Connection Lnk
LED on the front of the SNE2020G indicates a link has been established, if an SHDSL
connection has already been made. If an SHDSL connection has not yet been made,
the Ethernet link will remain disabled (as indicated by solid illumination of the Ethernet
Rx, Tx and Lnk LEDs) until at least one of the two SHDSL links has been established.

The SNE2020G connects to a PC using a straight-through Ethernet cable and to a hub
or a switch using a crossover Ethernet cable. For any other type of connection, the
circuit presented by the Ethernet device you are connecting to determines the type of
cable you need.
Ferrite Chokes
If ferrite chokes are included with your network extender, install them on all DC power
and signal cables. Position the ferrite chokes as close as possible to the body of the
SNE2020G.
