Well VDSL disappeared at midnight and it was off for ages so I rang my home phone from mobile and that restored my BB. Phone rang once and then cut off.

Well I have logged the fault with TTB CS and got the usual auto message but have a case number now but they say allow 48 hours for response.

Yes the phone in test socket had a dangly filter on. But with nothing connected my mobile cuts off after 2 seconds.

Does the socket still contain a ring capacitor or is it in the filter?

Yes, it does, but there’s one in a filter too.

The cutting off after a couple of seconds is called ‘ring trip’ … this is often caused by a rectified loop fault somewhere. You have ruled out it being on internal equipment or wiring,

Look at the dreadful weather of late, a wet joint somewhere I reckon.

You had your buried UG feed replaced some years back didn’t you ? Or was it just the 66 and lead into the property itself … can’t quite remember.

Ring trip is a well recognised fault. Caused by poor insulation. Either across the pair or between the pair and another pair's battery.

If it's across the pair they will likely appoint as is usually at or close to the customer. If it's battery, they will stick it straight out to the local line engineers.

I suppose with so many circuits not having battery on them any more, there must be fewer battery faults.

Its sad that these specific fault finding skills will eventually be lost with the introduction of full fibre across the country.

Yes that is correct the UG feed down my drive was replaced and a 66 was fitted. Line test has come back as rectified loop fault in or near property. Got the usual equipment checks email to rule out which I have already done so wait for an appointment.

Thanks for that FB has come back as rectified fault I suspect a chamber near me which usually fills with water but could be wrong.

Yes, but there’s now* more earth faults, the flip side of the same coin.





*I’m told.

Had the same problem on and off for years, has never been rectified, now on FTTP and copper which sorts out t'internet, but the phone at times can be dreadful, at end of present contract will be dropping copper phoneline. I hope you have better luck.
