Please log in for more thread options At random times, but less often at night, my ADSL modem loses its connection with the CO. It can be running fine for 4 hours, then quit, or quit every 15 minutes at other times. Totally unpredictable. It takes anywhere from 30 seconds to 10+ minutes to re-sync. Thirty minutes was the worst outage. I'm getting or exceeding the advertised speed of 1m/384k when it works, which is ~95% of the time. My phone line has had intermittent static for years. There are no apparent loose wires inside the house, which was built in the mid 70s. The ISP checked it out twice and all stats look normal when it's in sync. Of course the drops only occur when the tech isn't testing the line. They make it seem like future checks might find "the problem" but one guy admitted that the telephone line is probably marginal between my house and the CO 14,700 feet away. I think the wind blows or water condenses somewhere and destabilizes a weak link. How can anyone know where to check along that entire distance? I don't want to bother with continued service calls that won't find anything new. Is it common to just accept this as a limitation of DSL and be grateful you're rid of dialup?

Please log in for more thread options fixable. Tell your isp you have intermittant synch. Either they or the telco should be able to track it down. Meantime, check your filters: alarm/security system: active or not (call alarm/security company for filter instructions) utilities: does the meter report by phone? filter may need to be provided by utility company water gas electric paging or intercom system that uses phones: may require a whole house filter (POTS splitter) or separate line for dsl rollover lines: put the dsl on your fax line, not one of the rollover lines medic alert/reporting satellite (and rarely cable) box may use phone for premium services, such as pay per view external ringer or light flasher distinctive ring other phones: attic garage bedroom upstairs downstairs fax machine answering machine caller id box dial-up modem telecommunications device for the deaf (TDD) Check your cable, maybe try another cable for a while. | |||||||||||||

I have no alarm system tapping the line and there are no apparent bad phones or "trigger" events inside the house that precede the line drop. The timing seems purely random, unless someone in the neighborhood has spliced into the line and is doing something illegal. If it were a problem with a LAN cable, phone cable, etc., you'd think jiggling it would cause the drop. I've tested for that as much as I can (no inside wiring contract with the telco). I also switched to another phone jack and it had no effect. I doubt it's the supplied filters, and a tech seconded that. When it works, it works. That same tech admitted that at nearly 15,000 feet from the CO there are innumerable glitches out of my control. I'd like to know how they can trace something that could be anywhere from 100 to 10,000 feet away from my house. If it's in sync every time they come out, what evidence can they go by?

> by? > In most Telco's, standard line testing is automated. The test results for giving back an OK to the operator are geared to voice service and have some thresholds involved. That is, a slight imperfection in a given test parameter might still give back an OK when it really isn't completely OK. If they REALLY wanted to find the problem, they would do a "raw" test or a manual test and then they would visit each and every access point on your pair all the way from the CO to your house (regardless of the test results) and actually look for a problem. Keep making reports when you have long outages and pay particular attention to the quality of your voice service and report any problems there too. Also the general consensus seems to be that some modems are more prone to intermittently losing synch than others. Post your modem model and maybe someone else can tell you if it is suspect. Some have gotten so desperate that they dropped the speed of the link to achieve better "up time" results but it doesn't sound like you are at that point yet. Good luck! | |||||||||||||

For this reason. I think he should be dealing with the telephone service repair rather than the DSL repair service. Prior to contacting telephone repair, I would suggest checking the line at the NID using a regular phone. (Telephone repair will ask that you do this also). If you have the static problem with this test it eliminates inside wiring from the discussion. As I understand it, line static can cause DSL interrupts. In case you are not aware, DSL repair and telephone repair are separate entities. Robert | |||||||||||||
