Attenuation Jumping Between Low and High Values?
« on: October 30, 2017, 07:16:35 PM »

I have been trying to sort out my line that has been having problems for the past couple of weeks.  Engineers have tried to fix but still having problems after they fix one problem it is another.  Any ideas on what could cause the line attenuation to jump between a low and high values (20db between them) along with a corresponding high & low fttc sync speed? Thanks

20db !!!! I'd be surprised if you had a dial tone with such a wild 'swing' !!! Or at the least, a very crackly phone line.

As BS implied, it must be an intermittent connection, maybe a complete break in one leg when it's in the high attenuation state. The engineers really ought to be able to find it.

Yes it is crackly probably the worse I have heard. 20db is not an exaggeration!I take it I should send this back as a not repaired?  What should I be saying I have been fobbed off with wait x days and everything will be fine? Any pointers greatly appreciated.  Thanks

Edit:going for a resync record

I think you've already answered your own question. Don't be fobbed off.

You should be reporting a telephony fault to the supplier of your telephone service and state something like "persistent audibly noisy (crackly) calls". Report the problem by telephone and let the person who answers the call hear the problem. Do not mention your broadband service. You require the services of a basic telephone network services technician and not one who has been tasked to attend to a broadband fault.

Could you attach your Hlog and QLN (on high attenuation and on low attenuation)?
