Phone fine,BB dropping out.

Well,started this morning so left routerstats running while i was at work (graph below).
Usual things checked (test socket,filter e.c.t ) gave CS a ring and told it`s a 3 day wait while it`s looked at. It`s a overhead line and before today it`s been fine,but seems to have coincided with the wind,but if it was something loose/broke then i guess the landline wouldn`t work also?
There was a BT engineer working at the top of the pole but when i shouted up he was working on lines for properties opposite me and wasn`t something general he was sorting.
Apart from equipment failure,what else might cause a intermittent BB but a working phone?

....BT speedtest added. (Between the dropouts!).

Re: Phone fine,BB dropping out.

Your connection certainly doesn't look good for last night:

Does your phone line have any interference or crackling?

Re: Phone fine,BB dropping out.

Was 1st thing i checked,expected the phone to sound like a box of rice crispies,but sounded fine even when the BB was down.
Was just about to post this reply when yours popped up Chris...
Line seems to behaving itself so far this morning after the last drop @ around 3am, sync and NM way down from normal tho...

Re: Phone fine,BB dropping out.

Hi there,
Interleaving is applied as a modify order, so that's what that'll be - hope it does stabilise things for you, if not we'll test further and get the fault escalated. Interleaving does help in a lot of these sorts of situations though.

Re: Phone fine,BB dropping out.

Didn't know interleaving was off,  but as the problem suddenly started, wouldn't that measure be "papering over the cracks" therfore hiding a underlying cause?

Re: Phone fine,BB dropping out.

It's possible, but if the line conditions have changed and interleaving is now necessary to hold a stable connection then it's a legitimate fix. We'll just have to see what happens.

Re: Phone fine,BB dropping out.

Left routerstats running while I'm @ work anyway so I'll see what I'll  come home to later.
Be a pita if interleaving is needed seeing I'm less then 300m from the exchange. :-D

Re: Phone fine,BB dropping out.

Tried a soft reset this morning as the connection had been up for 20+hours...

NM stuck on 12.5 db /DL sync about 3k+ lower as a result, it seems and my uncapped UL is lower too.
Would it be a 3 day wait, or being ADSL2 i thought it should pick up straight away?

Has my uncapped upload been re-capped,also my NM seems stuck on 12db so DL sync is way lower that it should be for being so close to my exchange.
Just about to do a hard reset and monitor the connection with routerstats today.

Re: Phone fine,BB dropping out.

Question #75621505  can someone @ pn towers decipher that into English for me? Lol
Engineer visit requested, curious to the fact found in testing. :-)

Re: Phone fine,BB dropping out.

Hi there,
LTB: Lower Threshold Breach, basically your downstream speed is less than the fault threshold profile set on your line.
Multiple drops - should be apparent, basically the tests have shown that the line is dropping.
ILQ: Not sure about the I but I know LQ is Line Quality - if it's Amber it means errors and/or drops have been seen on the line. This isn't necessarily indicative of a fault itself but when taken into account with the line's length and usual operating conditions/SNR etc it can do.

5 min drop where PN were running tests @ midday. With a 9db downstream attenuation should i expect in a perfect world to have the connection maxing out?
Just done a BT speed test,upcapped uploads deffo gone,would that need re-ordering once the problems fixed?

Re: Phone fine,BB dropping out.
