The effect of odd xdslcmd commands
« on: February 06, 2015, 07:13:39 PM »

 No doubt this has been explored before but I was wondering on the purpose and possible effect of trying a few xdslcmd's

 Specifically [--us0 <on|off>]  [--dynamicD <on|off>] [--dynamicF <on|off>] and [--SOS <on|off>]

   I am thinking of trying them but expect the result may be no change or no sync.  Has any one tried them or is anyone able to advise on what they are?
  The normal states are :-
 VDSL2 profiles:
       .....
        US0     Enabled

Capability:
       ....
        dynamicD:       On
        dynamicF:       Off
        SOS:            On

disabling US0 I imagine would result in a lower upstream sync.

When I tried the above a long time ago none of them seemed to have any effect.

the billion 8800nl has us0 toggle in its gui, I disabled it and it had no affect.  Probably blocked by the dslam.

  It is probably good that that is on by default but I wonder if there might  be an advantage in having an odd resync (assuming it is not often) rather than the error burst which may come with SOS on and the line hanging on to its sync.

  In a similar way I have wondered on the sesdrop parameter and what that might do.  Maybe it drops connection at a SES?

A while ago JustAnother attempted to make a list of what a lot of commands in xdslcmd do.     His thread can be found here

sesdrop: Some sort of functionality to stop all error correction stuff in order to reduce latency on the line? See Think Broadband thread.

Unfortunately when I click the link I get "We encountered a problem. The reason reported was Access Denied."

 One at a time-  Disabling us0 seems to have no discernible effect.  The HG612 shows us0 disabled so it does accept the command and the setting survives a sync. However no impact here with an ECI DSLAM.

  Next one:  --dynamicD off is also accepted and remains shown as off after a sync.  However again no noticeable effect on the stats.
