Switchpack Configuration (SNE2040G-P)
Configuration switches for the G.SHDSL ports are on the back of the SNE2040G, numbered from
left to right, 1–8. Switches 1–3 on the SNE2040G-P together provide eight bandwidth options for
the four G.SHDSL ports as a group. Bandwidth cannot be configured individually for the
G.SHDSL ports.
NOTE: Configuration switches 1–3 are used for G.SHDSL bandwidth configuration on the
SNE2040G-P ONLY. The SNE2040G-S determines bandwidth via communication with its
partner G.SHDSL provider equipment. Switches 4–8 are not currently used on the SNE2040G
provider or subscriber models.
Position switches 1–3 on the SNE2040G-P according to the cable distance for your connection
and your desired G.SHDSL bandwidth. 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 SNE2040 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, traffic quality may be affected.
* The SNE2040G-P will run in Adaptive mode when switches 1–3 are in the Up position: the
four ports will train up to the best possible speed supported by the SNE2040G-P, the remote
G.SHDSL equipment, and the copper cable pair connecting the two.
