Thread: SNR Upstream Downstream problem

Rx Errors are not that uncommon, especially in BSNL network. This happens when the packet fails during transit. These are due to high latency. As long as they are not insanely high, that should be OK.

Sorry to dig up this thread again, but this is the most apt place I guess.

1.) What's the difference between a single SNR figure and two seperate figures (SNR D/s and SNR U/S) ?

The BSNL dataone tech-guy brought along his own modem, which shows only a single SNR of 19 db.

My modem shows two values - SNR D/s and U/s .... 14 and 6 respectively.


2.) Can a wrongly rated power adapter be a cause of lower SNR values?

(ie, 13.5 volts X 1.2 mA, instead of 12 volts X 1.25 mA)

U/S = upstream
D/S = downstream

1)its always split into 2.. if you see one , its mostly downstream..
2)There is a setting in the modem , i think it is ADSL 2+ and G DMT which once selected does increase the SNR to a little more.. it may not work always though.. worth a try.. try keeping SNR above 10 for D/S AND U/S
3)i dont think power adapter has anything to do with SNR
