I think SBC uses Litespan 2000's in their RT's.]]> http://www.dslreports.com/forum/Re-Lights-are-on-but-no-ones-home-11420073 Fri, 24 Sep 2004 18:30:57 EDT http://www.dslreports.com/forum/Re-Lights-are-on-but-no-ones-home-11419779
That's odd. I wonder why and I wonder why that would affect you or your CRC errors. I have CRC errors, but that is beacause of theage of the wiring/distance from the CO. The Dslam wouldn't have anything to do with that.

I now have a Lucent "Stinger" rather than an alcatel and I have fewer errors than I used to . . . just during thunderstorms. Do you know what dslam you have?]]> http://www.dslreports.com/forum/Re-Lights-are-on-but-no-ones-home-11419779 Fri, 24 Sep 2004 17:53:36 EDT http://www.dslreports.com/forum/Re-Lights-are-on-but-no-ones-home-11418610 www.zyxel.com/support/su ··· ex_f.php It contains a little (very little) more info about each command.

My experience changing the specific settings for the Samsung chip on my 645 had limited success. For two days, the settings that I changed suppressed CRC errors caused by impulse noise, but then my DSLAM reset itself one night and those changed settings are no longer stopping the errors. :(]]> http://www.dslreports.com/forum/Re-Lights-are-on-but-no-ones-home-11418610 Fri, 24 Sep 2004 15:42:47 EDT http://www.dslreports.com/forum/Re-Lights-are-on-but-no-ones-home-11417065
Here are the commands available to me on the 645R --

bert chandata close coding
ctrleint defbitmap dyinggasp linedata
open opencmd opmode perfdata
rdata selftest status version
vendorid utopia display rateadap
dumpcondition sampletime noisegt noisemargin
persisttime timeinterval defectcheck txgain
targetnoise maxtonelimit rxgain txoutputpwr
rxoutputpwr maxoutputpwr

Some of these look promising, but without some sort of manual my experience tells me that it would be foolish to start changing the values of things when I don't know what the defaults are.]]> http://www.dslreports.com/forum/Re-Lights-are-on-but-no-ones-home-11417065 Fri, 24 Sep 2004 12:48:30 EDT http://www.dslreports.com/forum/Re-Lights-are-on-but-no-ones-home-11409487 Viewing Modem Stats?

I currently use a variation of Bill_MI 's two-router method rather than the method that I posted in that link. What I had posted was a bit unstable and had to be "brought up" manually by making the DSL connection and then making the second link to the switch. The two-router variation that I now use is completely stable. I needed this because I collect line stats from my modem continuously. I've been debugging DSL line problems, CRC errors caused by impulse noise, for months and think that I've finally eliminated them with Trellis Coding. :)]]> http://www.dslreports.com/forum/Re-Lights-are-on-but-no-ones-home-11409487 Thu, 23 Sep 2004 16:20:16 EDT http://www.dslreports.com/forum/Re-Lights-are-on-but-no-ones-home-11409319
That's right. I can telnet into the router, but not into the modem.

The way I telnet into the modem is to disconnect it from the network and plug it directly into a machine that I have also taken off the network, then I can telnet into it.

I hardly ever go in there since it is set up as a bridge.

--There are many ways around this limitation with some other equipment added to your network.--

Do tell. Got a link?]]> http://www.dslreports.com/forum/Re-Lights-are-on-but-no-ones-home-11409319 Thu, 23 Sep 2004 16:00:54 EDT http://www.dslreports.com/forum/Re-Lights-are-on-but-no-ones-home-11408574
If I understand you correctly you are saying because you have a router between your computer and the modem, you can't telnet into the modem at will. There are many ways around this limitation with some other equipment added to your network.]]> http://www.dslreports.com/forum/Re-Lights-are-on-but-no-ones-home-11408574 Thu, 23 Sep 2004 14:27:35 EDT http://www.dslreports.com/forum/Re-Lights-are-on-but-no-ones-home-11408429
Samsung and wow does it get hot. I don't remember seeing Trellis as an option.

I re-start by power cycling. Because I am using NAT, and the router is in the way, I can't even ping the modem, much less monitor it.

I also have a Sprint 645R (router) here and I suppose I could use that rather than the modem and RT314 router, but all those settings to change! I run a web and mail server so there are some fancy rules in there to keep the cretins out.]]> http://www.dslreports.com/forum/Re-Lights-are-on-but-no-ones-home-11408429 Thu, 23 Sep 2004 14:07:13 EDT http://www.dslreports.com/forum/Re-Lights-are-on-but-no-ones-home-11408330 http://www.dslreports.com/forum/Re-Lights-are-on-but-no-ones-home-11408330 Thu, 23 Sep 2004 13:53:51 EDT http://www.dslreports.com/forum/Re-Lights-are-on-but-no-ones-home-11407131
Do you re-start the modem by power cycling or a software reboot from the CI menus? If the later, a monitoring program could automatically restart the modem after the modem reached an accumulated error threshold.]]> http://www.dslreports.com/forum/Re-Lights-are-on-but-no-ones-home-11407131 Thu, 23 Sep 2004 11:13:27 EDT http://www.dslreports.com/forum/Re-Lights-are-on-but-no-ones-home-11406931 http://www.dslreports.com/forum/Re-Lights-are-on-but-no-ones-home-11406931 Thu, 23 Sep 2004 10:43:04 EDT http://www.dslreports.com/forum/Lights-are-on-but-no-ones-home-11406271
Here is the problem . . . Frequent thunderstorms are driving me nutzo. What seems to be happening is that when the modem gets too many errors, it doesn't drop sync (all four lights stay on), but nothing can be pinged and no activity is present.

Only way to "fix" this is to manually restart the modem. During a thunderstorm, I sometimes have to restart it 10 times in an hour.

I used to use an Efficient Speedstream 5260 and when it got too many errors, it dropped sync, the router saw that and began "redialing" until it was connected again.

Is there a setting in there I can change to make this modem do the same thing? Cause cable is looking mighy good.]]> http://www.dslreports.com/forum/Lights-are-on-but-no-ones-home-11406271 Thu, 23 Sep 2004 09:08:09 EDT
