Hi what are your levels currently?
What was their reason for the repull? Is the newer cable thicker? They call it RG11, normal thickness is RG6.

Seems to me like because your signal levels on old cable have increased by 5db that.. If the new cable was thicker they installed it to give you a better signal, then in the meantime at some point the problem causing low signal levels was fixed, maybe the tap was changed or amp problem.

This then lead to upstream being too low causing the t3 errors.

Just guessing though.

But if you could post your current signal levels we can check for you if they are ok on the old cable.

I know, you would think you can trust vm staff but some you can't. On here there's really knowledgeable engineers who do things properly but round here they don't, that's why I got fed up.

6 years I put up with being told I had signal problems, what's worse is they lied to me as well.

Does sound botched but not surprising, was funny when I had my additional cable done, they pulled cable through on a Friday morning and left it coiled up next to the pavement which was a trip hazard.

So over the weekend I dug 12" deep into the ground, and buried the green cable ducting in sand and covered with protection to the same standards and regulations as any other cable.

Connected it up in brown box, then Monday morning first thing guy came to fix my telephone as they damaged it.. When he did that he connected up the other end inside the pit.

Late afternoon 2 guys turned up to bury the cable, but I told them it had been done already and they said they wouldn't of buried it more than few inches.. So I sent them away.. Was a bit annoyed they was, but at least now it's been done properly.

That other cable you mentioned is a telephone cable, the telephone was probably still connected on the old cable, and because everything was left connected the other end on the old cable they just left the telephone cable on the new one unterminated.

Handy to leave that in case you get a telephone cable problem they can switch that to new cable as well.

They don't use single cable, as they only have single cable for above ground usage, the underground dual cable is used because it has a tougher plastic insulation and the telephone wires are also covered in a waterproofing jelly. So if the duct gets flooded it remains waterproof and resistant to damp better whereas normal cable might fail sooner in those conditions.
