Is this a Virgin Media cabinet?


[link to this post]
 
Hi,
Any ideas how I can find out if this is a Virgin Media cabinet? (or one of it's former-companies like C&W etc).

http://tinyurl.com/5vlppaj (Google Street View)

It says CATV on the concrete slab just to one side. It's definitely NOT a BT cabinet (I have asked an engineer who was working on my line and it's not even on his map). There's also a much smaller cabinet very close to my house which is also in front of a slab which says CATV on it - again, not owned by BT.

I would assume it was VM owned, were it not for the fact that VM say our area is NOT cabled and they do not offer any services on my road other than rebranded BT wholesale products.

It's very odd - I'm thinking that either there's another cable operator I don't know about, or perhaps their database is wrong and our area actually IS cabled, but nobody can order because of the database problem?! Or maybe these cabinets are just monitoring points for the street lighting or electrical supply?

Nick.

Another long shot.... could it be the developers hand conduit and cabs installed at the time of the build for the local operator to use, but then didn't?

Round my way (Thamesmead SE London) across the road from me are loads of CATV cabinets, some are 3 right next to eachother, theres one giant one further along, some more dotted around. On my side of the road theres one on a corner and another about 60m from my house. Check the Virgin website and I don't live in a fibre optic area, so there are about 10 cabinets with CATV manholes, that Virgin probably didn't even know exist. Apparently when the town was built it was a trial area for FM over coax or something.

"By 1970 the Basildon Branch was running the Thamesmead project. Here, on the mudflats reclaimed from the River Thames near Woolwich, the Greater London Council built a new city within a city. Rediffusion London had a Community Service contract to provide an h.f. system to the first 9,000 dwellings. Incorporated in the Thamesmead project was to be all the latest developments of Rediffusion engineering. With 12-pair cable being used throughout, there was no anticipated problem with channel capacity. Two 405 and three 625 line television programmes and Radios 1, 2, 3 and 4 were being relayed at that time."

I was given this useful link by the Virgin Media twitter team.

I have contacted them on the cablemystreet@ email address and have been told that the cabinet is a VM cabinet, but it does not have any fibre going to it and it's not currently in use. It's an old Videotron analogue TV system which I think VM have decided to not take over or maintain. Apparently it's likely it will be upgraded to fibre as all the ducts are (obviously) in place. I'm not so sure myself.. I think it's more likely that VM will start reselling BT Infinity instead and deliver TV over that.

Now that would be quite a technological tour de force if they could pull it off. Umpteen channels of TV down a few hundred meters of twisted pair.



If you can't fix it with a hammer you've got an electrical problem.

Well, it's exactly what they do already on their own network. They just need to get the multi-casting working properly so each channel is only sent once down the back-haul. More likely, they'd install their own relays at the exchange so the TV distribution doesn't actually use the back-haul on a per-user basis. There no technical challenges they haven't already solved - a BT Infinity connection can easily handle between 4-10 full HD TV channels simultaneously (assuming 4Mbps each) which is more than the average house would ever use.

Their main problem would be getting the commercial agreement with BT sorted out.

Maybe but I doubt it. They certainly couldn't provide the same service as VM cable without replacing the twisted pair with coax.

You can run any TV service over an 20Mb internet connection long as there is suitable equipment at the cabinet or exchange to support it. You just have to use a different methodology to distribute the content. Virgin transmit all channels to every user, whereas BT would have to put in suitable relays in the DSLAM to send you only the channels you're currently watching. It's already being done with services like BT Vision - the only difference is, BT vision is currently optimised lower speeds provided by ADSL rather than FTTC. With relays based at the DSLAM / exchange, it wouldn't even use up any of your download allowance. Ideally, BT should fit these relays in the street cabinets, but I'm not sure if they've done that.

They aren't hardware relays it's software - the MSANs in the cabinets need to support both IGMP and multicasting.

The only implementation of this that I've seen is Talk Talk TV, formerly known as Tiscali TV and originally Homechoice. BT Vision is broadcast TV delivered via a Freeview box with VoD delivered via standard unicast stream.

http://i56.tinypic.com/mhx085.jpg I took a picture today of the big cabinet next to a regular one, the manhole covers say CATV Brickhouse. An Openreach engineer said that Virgin only do TV in the area no broadband or phone, I'm guessing thats analogue cable TV.
