DESCRIPTION

EXAMPLE

 

 

 

vdsl mode

This field displays the VDSL mode.

10BaseS(0)

 

 

 

vdsl Active flag

This field displays if the VDSL driver is active.

on

 

 

 

vdsl Max. upstream rate

This field displays the maximum upstream rate configured.

1562500 bps (0)

 

 

 

vdsl Max. downstream rate

This field displays the maximum upstream rate configured.

4166667 bps (0)

 

 

 

vdsl state

This field displays the VDSL state. VDSL goes through

1

 

several states before the VDSL link is up. For more

 

 

information on states, see the VDSL debug command.

 

 

 

 

vdsl long loop flag

This flag comes on when the distance from the P841C to the

off

 

subscriber VDSL modem (P841) is greater than a certain

 

 

distance (1 Km using 24 AWG (American Wire Gauge)).

 

 

When this happens, interleaving is enabled so as to prevent

 

 

bursty errors; however this decreases throughput.

 

vdsl sleep mode

Sleep mode means the VDSL chip is in power save mode.

off

 

This happens when vdsl Active is “off”.

 

vdsl auto flag

This field shows the current VDSL auto flag status ( “on” or

on

 

“off”). When this flag is on, the P841C will automatically

 

 

negotiate upstream and downstream rates up to the values

 

 

set using the upstream and downstream commands.

 

vdsl monitor flag

This field shows the current VDSL monitor flag status ( “on” or

off

 

“off”). When this flag is on and the VDSL link is up, the P841C

 

 

will automatically VDSL parameters every three seconds. For

 

 

more information, see the VDSL monitor command.

 

vdsl debug flag

This field shows the current VDSL debug flag status ( “on” or

off

 

“off”). When this flag is on, the P841C will automatically

 

 

display messages during each stage (state) of the VDSL

 

 

initialization process. For more information, see the VDSL

 

 

debug command.

 

 

vdsl auto upgrade NT

This field shows the VDSL auto upgrade status (“on” or “off”).

off
