Does VM suffer from subsidence issues?
Someone who used to work on a cable system in the past has told me this:
'To be honest, the overhead one was far better - as the underground one suffered from subsidence, with the entire estate slowly sliding further down the hill - pulling wall boxes off houses and dragging them under ground, and even snapping cables.' Does the modern system have the same problem? You'd think it would, but i've never heard of any incidents. He also said that their system used 60 to 65V (said to be the same as the UK telephone system) Is this enough to give you a bad electric shock? What does the modern day VM system use? |
Re: Does VM suffer from subsidence issues?
In my 12 years in the industry, working on a predominantly underground network (eg distribution tabs underground not just cables) I’ve never heard of a network subsiding and taking down wall boxes cabinets etc. There are cases where ducts etc have collapsed for various reasons, but not just due to being underground. The telephone network runs on 48v DC, and the HFC network is 60v AC, but the AC the will not be passing through customer drop cables, only down trunk coax to power amplifiers. The FTTP network is completely passive after the hub cabinet in the street

Away with your rudeness.
Thank you to everyone else. Are there any cases where this affects Virgin Media infrastructure? |

If the whole estate was subsiding Virgin cables would be the least of my worries.. I incidentally live on a hill so if my house started subsiding so would Gas & Water mains making it very dangerous indeed.
