I have had issues in the past, all between the house and the cross connect next to the VRAD.
First year of DSL on AT&T 'express' was good.
Second year of DSL on DSL-Extreme pro was good (better ;) )
Third year was where the issues started... I ended up having intermittent noise on the line causing sync issues (would be clean, then CRC errors and loss of sync for ~ 30 minutes), however it would happen infrequently.
Later during the year, SCE's 16kV line melted all the wires on my block (yeah - I have a piece of melted wire as proof).
After they reinstalled all new wires, service was good again... for a while.
Next year, similar to prior issues started ... ~ 1pm daily, I'd lose sync for ~15 minutes.
AT&T downgraded me to 1984/512kbps as they stated I was too far from the CO. Lots of CRC errors still occurred during that time, but no sync drop.
Finally, AT&T's Uverse crew was in the area - few minor issues with their contractors cutting my line completely, but 'finally' there's little to no CRC errors. I.E. They had to fix the 'water in the lines' issue to have working Uverse. TV service is less tolerant than an ADSL Internet service.

I'm at +10,000' according to AT&T, and they will not sell anything but 1500/384kbps to me :p most likely because of the complaints I've given their techs in the past.

My connection has been relatively stable from a user point of view. I rarely notice the resyncs except for the dropping of the VPN and can live with the occasional resync.

I think it's all weather related. The wind blows a little the line resyncs. Currently, with the warmer days, it's been solid. ]]> http://www.dslreports.com/forum/remark,20496015 Fri, 16 May 2008 22:38:44 EDT http://www.dslreports.com/forum/remark,20495975 TE : Thanks Zak. When I have noticed the loss the modem 'Line' LED is blinking. I'll keep an eye on it over the next few days and let you know if the problem still persists.

In checking the logs tonight, I show a few drops on the 14th, Nothing on the 15th and nothing on the 16th. By the modem logs, it doesn't show that you knocked me off but the VPN was disconnected today when I returned from work. :)

I've cleared the alarm log and here is my line stats from the modem. Funny that Remote Line Atten is now at 0.5db.

I typically only lose sync ~ 1/week or so, and its not like its down for a while... just a resync.
Line is typically stable for +100 hours before a sync reset, and I've reached almost 1000 hours some times.
Of course, AT&T claims I can only get 1500/384kbps here because I'm beyond 10,000'.

The line readings look good from here and the line seems pretty clear of errors. The only thing I see is an abnormal amount of Xmt Shaping drops on the line. Usually only see those when a customer is connected to a RT but my info says you are on a CO. These drops could somehow be causing the modem alarms but they wouldn't necessarily mean the line is actually loosing sync.

Have you confirmed loss of sync for sure? Is the DSL signal light on the modem going out when the drops occur?

I reset things on my end (Sorry if I kicked you off) to see if that helps at all. Let me know if it is still an issue and I will start a ticket for tier2 to do some line monitoring.

As long as I'm not doing anything, I have a good chance at keeping the SSH tunnel open. VPN (SSL VPN) typically holds out better, but its a throttled (corporate) connection, so I don't use it unless I have to.

I don't know what the logs mean in general... SMT session is my telnet session. SCE is doing work in the area (again), and we've experienced a few brownouts lately.

Don't get me wrong, I understand this is residential DSL service and there is no SLA. I can handle a few bumps in the road but a few days ago it was really bad and the only thing I can chalk it up to was the wind. If I'm using the VPN, I'll get disconnected about every eight resyncs or so. To be totally honest, I don't usually notice the resyncs at all. It's only in checking the logs that I see them.

It was a little windy yesterday. I'll keep an eye on it and post back if the resyncs get out of control.

When this was happening yesterday, My line stats looked good to me. Maybe, a modem acting up?]]> http://www.dslreports.com/forum/remark,20437024 Mon, 05 May 2008 21:35:26 EDT http://www.dslreports.com/forum/remark,20434991 dslx_gm : I have never seen that error before. If you are re-syncing my assumption is that what was causing the error. Are you still having a problem?]]> http://www.dslreports.com/forum/remark,20434991 Mon, 05 May 2008 14:57:55 EDT http://www.dslreports.com/forum/remark,20431802 TE : I'm having some problems tonight, my modem keeps loosing sync. In troubleshooting on my end, I noticed that in the alarm log on my Broadmax modem I have the following condition ...

Sun May 04 15:29:21 2008 : WARNING : ATM VC Congested : Interface - aal5-0, PortId=7, Vpi=0, Vci=35

Would this indicate the ATM virtual circuit at the CO is congested? Net has seemed slow tonight but I thought it was due to the resyncs.

I've attached the modem's alarm log and the sho dsl stats.
