Finally Got it activated todayHere are my stats for 590 NUSNR Margin 43.5db 18.5db dBLine Attenuation 21.0db 37.0db dBLoss of Signal 0 0 CRC Errors 0 0 Data Rate 506 Kbps 252 Kbps kbpsLatency Interleaved InterleavedIs it good or bad?Also I am getting 31-32 KBps Downstream( 250 kbps)Myu upload test showed only 88 kbps
 
your figures are pretty good as far as SNR and Line Attenuation are concerned...Data Rate i'm guessing should be 2048 kbps 😛
 
My lines stats have changed within few hoursSNR Margin 43.0db 16.0db dBLine Attenuation 22.5db 40.0db dBLoss of Signal 0 0 CRC Errors 0 0 Data Rate 506 Kbps 252 Kbps kbpsLatency Interleaved Interleavedguys any idea why i am getting 32 KBps constant while my data rate is sync to 506 kbps
 
your figures are pretty much the same...as far as your question is concerned, even i'm wondering why i don't get above ~60 kBps when i'm synced at 2048 kbps...go figure 😛
 
I feel there is something else which is a limiting factor at MTNL's end. Bcoz i am getting pretty consistent 32 KBps.....that is my upper limit is at 256 kbps.btw do the snr and line att values keep changing from day to day.
 
before this 2 mbps thing, i used to always get synced at 31...but now it's very erratic...my lowest went to 12 (that i noticed)...and to my suprise it keeps changing without even rebooting the modem...earlier i used to think that once u're connectd, you SNR won't change, but that's not true... :huh:
 

Code: 
Noise Margin (AKA Signal to Noise Margin or Signal to Noise Ratio)Relative strength of the DSL signal to Noise ratio. 6dB is the lowest dB manufactures specify for modem to be able to synch. In some instances interleaving can help raise the noise margin to an acceptable level. The higher the number the better for this measurement.6dB or below is bad and will experience no synch or intermittent synch problems7dB-10dB is fair but does not leave much room for variances in conditions11dB-20dB is good with no synch problems20dB-28dB is excellent29dB or above is outstandingLine AttenuationMeasure of how much the signal has degraded between the DSLAM and the modem. Maximum signal loss recommendation is usually about 60dB. The lower the dB the better for this measurement.20dB and below is outstanding20dB-30dB is excellent30dB-40dB is very good40dB-50dB is good50dB-60dB is poor and may experience connectivity issues60dB or above is bad and will experience connectivity issuesOutput PowerHow much power modem (upstream) or DSLAM (downstream) is using. Maximum recommended is about 15dB. The lower the power the better for this measurement.
Two diff brand of modem will always show diff attenuation and snr fig and these change acc to line condition.

mere 2 paise 😛(my 2 cents)

Having stayed with Sify for more than 3-4 years.....I have finally decided to move for MTNL triband

I have applied for 590NU plan with modem. or should i buy my own modem.....how much does an ADSL modem cost.

Is it worth giving a Rs 500 non refundable security and Rs 50 pm or should I buy my own CPE.

Also How long does it take for them to install the connection. I wanted to get it installed in JAN as I am pretty busy these days but applied today as they have waived off installation , testing and 1st month rental till 22nd dec.

Is there anything like a specific model or brand of modem that i should ask them[/b]

You should have been purchased Adsl PCI internal modem at Rs. 999. It is works fine.
 
The higher the number the better for this measurement.
6dB or below is bad and will experience no synch or intermittent synch problems
7dB-10dB is fair but does not leave much room for variances in conditions
11dB-20dB is good with no synch problems
20dB-28dB is excellent
29dB or above is outstanding

Line Attenuation
Measure of how much the signal has degraded between the DSLAM and the modem. Maximum signal loss recommendation is usually about 60dB. The lower the dB the better for this measurement.
20dB and below is outstanding
20dB-30dB is excellent
30dB-40dB is very good
40dB-50dB is good
50dB-60dB is poor and may experience connectivity issues
60dB or above is bad and will experience connectivity issues[/b]

where is above written in that link??
 
Guys I am a bit suspiciousI am getting speeds exactly the same I used to get on SIfy i.e 31-32 KBps download ( almost constant )and fluctuating 8-16 KBps ( avg 13Kbps) upload. I cannot beleive this.What 's more is that I am syn at 506 kbps down and 252 up.Could it be somthing in MY PC that is limiting these speeds. Could it be some software installed by Sify that is limiting these speeds
 
well dude GSV13, all i meant was the info was already there, in case u missed it...if u did it with purpose, keeping in mind the detailed info, then it's fine...also if u do a google search on "snr and line attenuation" you'll get 357,000 results...so i don't really think that we can have all those results here...if u see my sense 🙂
 
^^^ yeah i could feel ur senses though unable to see it Lol 😛@boygr8 i read it somewhere bandwidth is controlled via two places one is line syc rate & another is directly controlled at exchange or Dslam! nothing to do with sify!
