Normally true regarding SCP's, however I know of at least 2 where I live that have had the 42/1 (for example) SCP cab FTTC'd

Now that's very interesting. That suggests BT are willing to contemplate some rearrangement of the D-side to improve FTTC behaviour, but isn't something I've seen hinted at all so far...

Well I had infinity installed today my estimate was 8.2, the engineer was amazed as I was getting 30 on there test gear. I have ran a few speed tests and I get 27 down and 2 up, I was over the moon after being on 1meg for years

In reply to a post by Adsl24:

If you PM me a postcode I'll check which cabinet you are on, and how far away you are.

No special work should be involved really. Treat the SCP as a PCP, run Fibre to a new FTTC cab, link copper from SCP to FTTC cab. The voice line will still co through the PCP on the way to the exchange, but the FTTC service will not go via the PCP.

I know the setup for an FTTC cabinet has to define a power mask, to ensure that the VDSL signals don't interfere with an ADSL signals passing through direct from the exchange. The power mask chosen varies with the length of the E-side.

In designing those power-masks, they only have to account for the ADSL frequencies and distances - as VDSL will never come direct from the exchange.

I can't help but wonder if allowing an FTTC cabinet at an SCP will require *that* cabinet to have a power mask that caters both for ADSL signals from the exchange *and* VDSL signals from the parent PCP.

It's easy to say that BT wouldn't do this - that they would not supply VDSL from the parent PCP, but would always choose to supply from the child SCP if present. However, I think things get a bit stickier for some of the LLU (or sub-LLU) cases where a non-BT operator can install their own FTTC equipment, and do so at the parent PCP.

I have read (on this forum) someone propose the idea that special dispensation be requested for a cabinet where it is known to NOT have any exchange-based ADSL - one done by Rutland IIRC. The counter against this would be that you never know what LLU-based stuff will happen in the future.
