MTNL Broadband: 8mbps Plans

[sanke1]

Is that on a VDSL?

No. mine are for ADSL.
See here after 22 days of uptime:

Wait...no disconnects in 22 days?

that is the modem uptime !
.......... unless he has a direct pipe straight into mtnl servers !

Switching to G.dmt has helped a great deal. Lower speeds no doubt, but lesser errors and finally saw a 10 hr session. Moved back to ADSL 2+ for testing and same story - so it looks like they haven't done anything from their side.
Any idea what their promised service quality is supposed to be for these plans?

80% ie 6.4mbit minimum

No disconnection. Its ADSL uptime and NOT modem uptime. The IP session is 10 hrs.

Thanks. 80% is a TRAI rule, obviously. And that is achievable on g.dmt for me with the SNR Margins, so can't really complain there. The innumerable CRC errors are indicative of line quality and I'm afraid MTNL has no SLA in that department.

Right. Sadly the rules don't cover latency and other line parameters.

Some headway this looks like. CRC errors (and subsequently HEC) have reduced a lot.

Sweet success:

Just bumped upon this post .... How did you manage to get speed profile of more than 8 Mbps ( 8192) ? I asked at the exchange to increase by speed profile bit more than 8192 , he said its not possible as your plan itself is 8 Mbps !
