Thread: intermittent connection

mine is home bsnl 125 dataone plan. i am experiencing interruption for the last two months. earlier i used to get it correct. every now and then the connection is gone. the dsl light is on always. but the status indicator on the modem goes. the first three lights are on but the status indicator goes and the taskbar computer icon goes black. (when connection reestablished it is glown) within a few seconds it is available. but due to this interruption i am not able to download from sites like rapidshare which does not allow resume capability. i can download small files. but when the question of downloading bigger files it is failed.the details are as following:-

modem UTstarcom
modem model WA 3002 G4
mode-G.DMT
status-No defect
type-interleave
Line config_trellis on
snr margin-11.9, 26.0
attenuation -63.5 31.5

in the bandwidth meter --it is shown-
bandwidth -670.39 kbps( i used to 1.54 mbps earlier in march 2009)
download rate-64.kBps
kindly comment on snr rate.thanks

attenuation -63.5 31.5

1.Your line condition attenuation is very high/ worst.
Means too many joints en route to your location.
Could be more than 6 KM from Exchange. confirm.

2. Complain to BSNL tech staff Your Exchange.

3.Inspect cables/joints for corrosion/balckening/oxidization/ High resistance
contacts etc.

4.ensure ALL phone connected after ADSL splitter In Phone port.

5. If Phone is noise free without crackling sound etc .
line man will say their line is fine
Approach your J.T.O.

Your attenuation values are very high. Lodge a complaint at your local exchange.

I feel it is beyond our scope now.

Check your set up is as given below.

Use short cables.
Remove additional telephones one by one
and recheck SNR/Attn.

SNR should Increase .( above say 15 db )
Attn should decrease ( say around less than 30 db)
