Who is responsible for BT's core network?


[link to this post]
 
If Openreach only looks after the local loop and exchanges which division looks after the core? I've come across 'BT Technology' that sounds like they might be the ones.

Indeed.
OR look after the Access network, TSO (that was - there have been several name changes over time) manage core networks which the customer facing divisions (Consumer, Wholesale etc.) provide products and services over.

Openreach also own the backhaul from exchanges too. If you're an ISP that requires backhaul to your own building that is something you purchase from Openreach.

Not quite.

Wholesale manage the backhaul, whether they get Openreach to physically maintain the cables, routers and switches I'm not sure. It could be TSO.

The MD and Chief Architect and his team within BT TSO are the team responsible.

Yes, basically TSO run the head end electronics beyond the OLT cards , switch and transmission equipment, and openreach run the cables and street DSLAM and PON equipment.

Here's a link:

I suppose it depends on how you read the initial question. Wholesale ARE responsible for BT Consumer's backhaul, presumably buying the EBD product from Openreach. . However someone like Sky, TalkTalk, Voda, Zen etc who want their own backhaul would used the EBD product from Openreach directly, not via BT Wholesale.

Sky mostly use virgin provided backhaul which uses cable link to their own fibre. I suspect talk talk do similar with their own fibre. BT wholesale mostly likely use SDH systems from TSO for most of their main network

Vodafone own and presumably use the C & W network where available. Which is a lot of places.

Guys you're telling me stuff I already know here. To say Sky "mostly" use Virgin Media backhaul is so, so wrong by the way.

I know Vodafone have their own network but they have to pay Openreach to link into their network. Go to most exchanges and you won't see C&W ducting outside, or Virgin Media. This happens every time we discuss this subject and most of you don't work on the network so....
