G.SHDSL Standards

The IES-1000 supports both G.991.2 and the G.hs standards.

Configured Versus Actual Speed

You configure the maximum and minimum speed of individual G.SHDSL ports using the set port 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 port command, the actual speed is always a multiple
of 64 Kbps. If you enter a speed that is not a multiple of 64 Kbps, the actual speed will be the next lower multiple
of 64Kbps. For instance, if you specify 600 Kbps for a port, the actual speed for that port will not exceed 576 Kbps,
and if you specify 660 Kbps, the actual speed will not be over 640Kbps.
Note that when you configure a G.SHDSL port, the upstream and downstream speeds are the same. The list
port command displays the configured parameters and actual speed of a G.SHDSL port.

G.SHDSL Commands

The commands related to one subsystem are grouped under a primary command of that subsystem, for instance, 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
