Ok just to summarise and clarify this thread for easier understanding that Docsis 3 cabling is used for the virgin media broadband network to the cabinets on the streets and from these cabinets to houses/properties are coaxial cables that no matter how old they are and as long they can carry digital tv signals there will be no bottleneck involved whatsoever.

Correct?

No there is no such this as DOCSIS 3 Cabling

VM Use fibre to the cabinets and coax to the premise.

DOCSIS 3 is just a specification of transmission network and the related equipment associated with it.

Actually the fibre only goes to the big VM cabinets known as optical nodes. Most of the smaller street cabs are fed by coax too. There are amplifiers in the smaller cabinets and they feed cabinets further down the line,

It's fascinating how what was once set up as an analogue TV distribution system was adapted to provide a broadband service. Well worth reading about if technology interests you.

Update:

Engineer came earlier however he did not complete installation as he said he couldn't see wires underneath the CATV manhole cover on my street outside my property. He said someone pulled the wires out hence he couldn't see them. Strange thing is if someone pulled the wires out then how come we can still see the existing wires on the front wall of my house going to the underground.

You say 'manhole' , I'm guessing you mean the small ( 3 inch) square plastic access point usually in the footpath outside your home
It's quite easy to lift the lid on this access point in front of your property and see for yourself , as you say , if the cable still exists on/in your property , why wouldn't it also exist in the footpath, but in a way, you are going to get what you wanted, and that is a new cable , even though the 'old' cable would have been absolutely fine to deliver DOCSIS 3 , as that is the transmission standard rather than the specification of the coax cable

Dont know whats going on that's what the engineer said. He said its has to be a 2 man job that needs to be booked.

Does that mean digging up and ruining my front driveway?

No.

There will be a duct between the nearest cabinet and the little access box in the street outside your house. From there to the outside box on your wall they will probably tack it along a wall or fence, they may route it through a flower bed but there is virtually no chance that they'll dig up your drive. If that amount of work is needed they'll just refuse the installation. From that box it will be taken along your house wall then through that wall to where there will be an indoor box,

As I mentioned in my first reply the street cabling isn't done by the installation team and sfaik the blokes who do that don't do the indoor installs. The street cabling doesn't need you to be in so probably the next you'll hear is another installation appointment,

DOCSIS is the protocol, the "language" spoken over the cable.

DOCSIS3 allows for much faster speeds than DOCSIS1, but it's still the same cable.

It's like ADSL1, ADSL2, and VDSL used by BT over the same copper phone line.
