SNE2000G-P and SNE2000G-S SNE2-A2-ZN13-10
Configuring the SNE2000G
Configuration switches for the SHDSL port are on the back of the SNE2000G, numbered from
left to right, 1-4.
Bandwidth (SNE2000G-P Only)
Switches 1–3 on the SNE2000G-P provide eight bandwidth options for the SHDSL port.
Distance capabilities listed in the following tables 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 SNE2000G 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 a link is achieved under such conditions, it
may have a low data rate.
NOTE: Bandwidth cannot be configured on the SNE2000G-S. Subscriber units determine
bandwidth via communication with their partner SHDSL provider units.

* Adaptive mode allows the SNE2000G-P to train up to the best possible
speed supported by the SNE2000G-P, the remote modem to which it is
connected, and the copper cable pair connecting the two. The maximum
distance for an SNE2000G-P in Adaptive mode is 25,400 feet (at
144 kbps).
