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.
