Well our cables date back to 1991.. so we are lucky they are even working :P
Output Power (Up/Down) [dBm]: 12,0 / 17,5

Line Attenuation (Up/Down) [dB]: 18,0 / 32,0

SN Margin (Up/Down) [dB]: 10,0 / 11,5

Why is my Snr so low ?? I remember that it used to reach 20db months ago but nowadays it's always like that.
Hey Guys, hope someone could help me out here.

Considering that I have 16 dB line attenuation (about 1.2 Km away from the Mazraa CO), my theoretical maximum speed is 22 Mbps. Now I realize that this is a theoretical maximum value but the max bandwidth displayed by my modem (ST546 on ADSL2+) is 15 Mbps only despite having a good SN margin of 34.5 dB.

Is my actual maximum bandwidth being limited to 15 Mbps because my target SN Margin is actually set too high? i.e. the balance between speed and stability is tipping too much in favor of stability in my case?
After researching, A LOT, on the matter I got some hypotheses which may be completely irrelevant as I have limited IT expertise:
Perhaps the SN Margin is set too high by Ogero (maybe I'm being put on a stability line profile) or maybe it's a modem problem (it's a ST546 which is bad on its own:p) especially that I do not have it connected to the UPS so it reboots at least once every day and as a result of that, the DLM (Dynamic Line Management) does not get to do its job and reduce my SN Margin progressively as it thinks that my line is unstable due to the reboots?

I would really appreciate it if someone could shed some light on this matter as I am considering whether I will subscribe to the uncapped speed plan or not.

EDIT: Regarding the big number of errors, these only occur on startup when synced with ADSL2+ and stop after the modem is fully booted. I read somewhere that this is normal for the ST546 when synced in ADSL2+. However, the FEC errors are only occurring today so it seems like it's a CO related problem (Mazraa CO).
@Doom it is suggested here before to check the margin during a power outage (you should connect the modem to a UPS though) because the margin could be greatly influenced from electric fields and such so if you can when the power is out check the margin, and hassan your problem is very strange why don't you call ogero and ask them your max rate ?

When you reboot the modem, do the FEC ,CRC and HEC errors reset? or those are accumulated values? because if those are errors during your 7 hours up-time, they are too much.
Basically, i live 1 km far from Mazraa CO, and my current max speed now is 12 Mbps with SN Margin (Up/Down) [dB]: 24,8 / 17,7. so max i can go is 15-17 Mbps without my SN margin deteriorating too much

Edit: i had FEC errors yesterday (Mazraa CO) but not that high FEC Errors (Up/Down): 23 / 69.848 (10 hours run-time)
I went today to central jbeil to upgrade to one of the new plans, and they told me i can't do it now, i can only choose another plan starting july 1, and it will be applied on august 1.
is their a chance that i talked to some misinformed people? mr kreidieh said that we can get the open speeds next month.
Ask first @ogerotelecom, then if they dont answer right - him in twitter!
It seems like private ISPs will most probably lie or simply throttle the real connection speed we can attain based on our stats. Hopefully this wont happen but knowing this country it is highly probable.

@Georges01 Wait till next thursday and ask again. As they might have not been informed formally in the first place and just heard rumors or gossips.

In bir hassan central they said : "to come after 15 days or 10 days minimum" they said the reason behind this is they are waiting for the official gazette

Higher sn margin = faster and stable internet , it's a good thing not a bad thing
Ahmad Toutounji wrote Higher sn margin = faster and stable internet , it's a good thing not a bad thing
Yeah i know that. but what is the point of having a 30+ SNR margin and download speed of 4 Mbps? the ideal is to have the maximum speed with a SNR margin above 10 (and not fluctuating).
Ahmad Toutounji wroteHigher sn margin = faster and stable internet , it's a good thing not a bad thing
That's what I thought at first but according to what I later found out, SN margin needs to be tweaked (fine-tuned) to find the perfect balance between speed and stability in a sense that a VERY high SN margin is not necessarily good for you since you'd be giving up some speed for too much stability. According to what I read, most ISPs (not in Lebanon) usually aim for a SN Margin between 6dB and 9dB since that would give you (the end user) the maximum possible speed while ensuring that your line is still stable (value of SN Margin below 6dB leads to instability and frequent disconnections).

Again, I may be completely wrong but this what I found out while looking up the subject on the internet.

Major Positive:

Plan Switching will be easy on 1515

I have questions:

Why a VDSL modem is required , I know speeds hover around 60Mbps vs 24Mbps on ADSL , what are the other benefits. I am 700m away from the CO and the test day it reached me about 17Mbps. On other way if I chose 4Mbps Download or Unlimited speed , the regular ADSL model will handle that. Is there any major difference other than the increase of speed a dsl router model can handle ?


If I chose dedicated 4Mbps / Unlimited , Synchronized DSL (Upload = download) which is technically similar to HDSL , do I need an HDL modem?

Fiber optics needs a special modem right , any reference of fiber optic modems, or any one installed that in his home?
I only saw the fiber optic modem when i was living outside , but no worries about it , we wont needed before 2020 at the earliest

Latest news from ukraine 900mb download 800 mb upload packages started to be available , lucky us we are getting 17mb soon, no complaining though , better than nothing i guess

roudy5 wrotehassan your problem is very strange why don't you call ogero and ask them your max rate ?
Just called Ogero and decided to keep it simple, so I just asked about the maximum speed I could reach on my line.
The employee answered that I have to wait till the new plans are in effect to determine my max bandwidth. Either that or I have to go to the Mazraa Central and submit a request ("Talab Kashef" or something like that).

In short, it is highly doubtful that Ogero will help me answer the quesitons I had.

Send an email to thepeople@ogero.gov.lb asking about your max speed and tell them your landlind number, they simply reply to you with your max eligible speed, they already did it for me and for 6 friends of mine.
