I don't believe there was any suggestion in the replies in this thread that the leased line would share the incoming fibre with an FTTP service. The leased line has to be a separate fibre back to the aggregation node

That was the question effectively posed by the OP

But leased lines can use a CBT port to provide service, then a separate fibre feed into the property

Can they really?? I thought every port on a CBT was effectively taken back to the corresponding FTTP splitter output. Are you saying that's not the case?

AIUI, there should be more ports provided than properties covered, so some (1) are potentially free for leased lines. The splitter is built into a node so fibres can be spliced straight through if needed.

That would effectively turn a splitter node into a new sort of fibre aggregation node. Whilst I don't deny that it's possible, would you really want to do it?

In reply to a post by witchunt:

How though? You’re then into the realms if sharing fibre again, which defeats the object of a leased line.

Openreach CBTs do not incorporate a splitter. A 12 port CBT has an input cable with 12 fibres. The leased line service will also likely share the same cable all the way back to the aggregation node unless there is no spare capacity on the cable.

Theoretically yes there should be spare cores from the Ag node to the splitter node which could be used for EAD service.

Openreach blew a 12-core fibre bundle/unit into the prem. when I had my EAD service connected. That’s pretty much standard fayre.

You’d be very much more limited if the ‘FTTP’ infrastructure up to and including the CBT was used to provision EAD.

A pretty [censored] solution (putting it bluntly) - for EAD anyway.

It's still a dedicated fibre for the leased line, only sharing infrastructure not the individual fibre or its bandwidth
