G.SHDSL Overview

Refer to the web configurator chapter on G.SHDSL for background information on G.SHDSL.
25.2

Configured Versus Actual Speed

You configure the maximum and minimum speed of individual G.SHDSL ports using the set profile
command. However, due to noise and other factors on the line, the actual speed may not reach the maximum that
you specify.
Even though you can specify arbitrary numbers in the set profile command, the actual rate is always a
multiple of 64 Kbps. If you enter a rate that is not a multiple of 64 Kbps, the actual value will be the next lower
multiple of 64Kbps. For instance, if you specify 2100 Kbps for a port, the actual value will be 2048 Kbps, and if
you specify 2120 Kbps, the actual value will be 2112Kbps.
Note that when you configure a G.SHDSL profile, the upstream and downstream speeds are the same. The
minimum rate must be less than or equal to the maximum rate. The list port command displays the
configured parameters and actual speed of a G.SHDSL port.

G.SHDSL Commands

Use these commands to configure a SAM-1008's G.SHDSL ports and profiles.
The commands related to one subsystem are grouped under a primary command of that subsystem. To configure
the G.SHDSL parameters, you must first enter the G.SHDSL subsystem by entering the gshdsl command as
shown next.
Syntax:
192.168.1.1> gshdsl
192.168.1.1 gshdsl>
When you see the 192.168.1.1 gshdsl> command line prompt, you are ready to enter G.SHDSL
commands. Enter the home command to return to the "192.168.1.1>" prompt.
