ADSL line stats check.. line keeps dropping

bledd · 1 Jul 2015 at 23:05

This is a long line, ~4-5 miles from the exchange, it used to be pretty stable. For the past few months, have been having multiple disconnects every day.

Does the same with BT HomeHub and DSL-N55U.

Modulation : G.Dmt
Annex Mode : Annex A/L
Line State : up
Lan Tx : 1222222
Lan Rx : 1064101
ADSL Tx : 26982
ADSL Rx : 263409
CRC Down : 58
CRC Up : 6738
FEC Down : 131
FEC Up : 46024
HEC Down : 47073
HEC Up : 98
SNR Up : 7.0
SNR Down : 9.0
Line Attenuation Up : 31.5
Line Attenuation Down : 63.5
Data Rate Up : 416
Data Rate Down : 1760

I think there may be a line problem as it's dropping far more often than you'd put up with.

Thanks

I would say looking at that the downstream SNR is a little too low.

Quite a few HEC errors on the downstream. I'm not sure if that's just a feature of a longer line though. What's the uptime?

SNR looks fine to me .

I blame this hot weather
My speeds have dropped to 2.5 meg from 3 meg since it got `warm`

Used to be maybe one drop a week or so, now it's multiple drops per day.

Can you hear any noise on the phone line ?

You need to start running a monitoring program to record the line drops

There is no clue in the stats

Hi Mine has been the same I didn't know if it was my router on the way out to be honest, I contacted my ISP and they have run a number of tests and cant find anything wrong with the line.

I have an Netgear DG834N I could try on the line, I just cant seem to port forward well on it for my CCTV system.

Any recommendations? I can use either a dsl-n55u or BT homehub3

Try runnning a quiet line test and listen for any noise (particularly crackling).

Dial 17070 (preferably from a corded phone) and then press Option 2. If there is noise, you have a phone line fault.

My stats are apparently very good for my distance from the exchange.
