ZXDSL 831 CII problem

Guys i have ZXDSL 831 CII modem with four out points, i have been told by a frend that my downstream and SNR are messing with my DSL speed, and i am facing problems with my net speed, so if any of you can guide me how to fix these values of SNR so my downstream gets fixed

location? exchange?

any noise in phone?

copper or ONU line?

I THINK ITS COPPER LINE.

DOWNSTREAM 4096

UPSTREAM 1020

SNR MARGIN US/DS 9.0/24.0

LINE ATTENUATION US/DS 19.6/36.0

POWER US/DS 12.3/18.3

ADSL Mode Setup Auto Sync-Up

LINE IS CLEAR

NO JOINTS IN LINE

Dude your SNR margin is not bad. And its WAY better than that of mine.

My SNR DS margin stays at 5-7 , and Line attenuation 54-56.... I'm surprised my DSL still works!

BTW I also have ZXDSL 831CII.

Anyway, by looking at your line values it seem you should NOT face any problems!

What is your connection speed? and what speed do you really get on downloads? does your connection stays stable i.e stay connected?

well i dont know if this SNR margin of my router is better then yours but i had no problems with my previous modem, coz download speed was stable 118kb/s to 120kb/s on 1mb connection. now its average download speed is 88kb/s to 95kb/s and somtimes it gets disconnected for 5 to 10 minutes

I have the same modem (ZXDSL 831 CII). How can I increase my SNR? Someone told me to tell ptcl to check my pairs. I have complained but they don't listen. I have no joints. I have 1 MB connection. (misri-shah exchange karachi)

PS. I am unable to sync at any other mode except g.lite.

Challenger, how is your speed now?

nab, your downstream SNR is low, same as that of mine. But your line attenuation value is better than that of mine... mine stays at 55-58!!!

Are you facing any serious problems? If your download speed is fine and not a lot of disconnections, this low value can be ignored. However if your connection is not working properly, then try few things on your own like,

Try changing your ADSL line mode to G.DMT / ADSL2 / ADSL2+ from G.LITE. I use G.DMT and it works better than other modes.

Well I am not facing any big problem. But isnt my SNR on border line? there isnt any room for variance in my snr, if it goes low it will disconnect right? Also if I upgrade to 2Mb/ptcl upgrades to 2mb, then will I be able to get 2mb download speed?

And I mentioned in my previous post that I am unable to sync at any other mode except g.lite. So I cant sync at g.dmt.

Hey this is my device information... PLease suggest whether its good or not...

Your SNR Margin and Line Attenuation are both awesome!

you got good values bro! but would you like to tell your connection package and the way you are testing download speed!

I am also having ZTE-831CII and mb package and only 1 joint in my cable check wather my status is GOOD??

It restarts almost every half hour I mean dsl light starts to blink and sometimes speed gets too low that i have to restart it then it works fine for 20 mins and again........I am having copper line. FIRECRUZ plz help!!!

^ Try changing your ADSL mode to G.DMT

^ No no

g.DMT is even worse for the line stats (only good for better pings)

@fahad

which exchange is ur number attached to?

inn case its out of rwp/isb call ur exch and get a clean pair!

SNR is better then before which is good but I am guessing you live far away from exchange right? So there is really nothing ptcl or you can do regarding attenuation. only solution is to get ONU line.

But anyways your stats are reasonable now.

ok thanx.......but im confused weather mu SNR is 8.5 or it is 22.8???

^ Your upstream SNR is 8.5 and Your Downstream SNR is 22.8

Your upstream SNR effects your uploads while your Downstream SNR is 22.8 effects your downloads.

take it as 22.8 ! as US is always < DS

not that good stats but good enuff to run dsl on ur current rate!
