Almost the same? So FTTC will manage 330 Mbps, with its 30 Mbps upload?

In reply to a post by MrSaffron:

FTTC cabinet fibre is part of the GPON network, Openreach has plenty of simple maps showing the fibre/node/splitter arrangements.

They pull / blow extra fibre well above any requirements for the FTTC network. For FTTPoD they take one of the unused fibres in the network and build out to the home via an optical splitter and hook that fibre into an OLT in the headend.

All the FTTC hardware is connected via dedicated point to point links back to the handover point. Having the FTTC network there makes the civils, etc, for running the fibre to neighbourhoods economically viable in the first place but there the dependency ends. Zero shared components whatsoever, the FTTC cabinets are not connected to the GPON network.

Also none of the Huawei DSLAMs support GPON use as backhaul GE / 10GbE only

The same seems to go for the ECI:

Which is wise, GPON would be a more expensive solution compared with point to point fibre to cabinets due to increased costs either side of the link. Not to mention that the main reason for Openreach using GPON is to avoid having to offer physically unbundled fibre

Well at any sensible price, Would he want to pay the cost of that?

They might, they might not

BT Retail is doing FTTP 160 Meg for £35 a month.

Actually, it does... when the power goes down.

Back when I worked on PABX's... using the most modern signalling systems around, digital lines on 30B+D connections... one of the requirements we had to test against included using very old, hand-cranked magneto military field telephones.

Just in case...

That would be half at moment, or even about a quarter of the 330 Meg product.........

80mbit to 330mbit download little real world usefulness although to some people I respect that will be valuable.

The real improvements now looking for is on upload and 20 to 30 seems tiny compared to what we know FTTP is capable off. BT seem to be treating upload rates on FTTP like platinum. Although a big advantage of course with FTTP should be there be no SNR issues and DLM would be retired.

I would consider 100/100 far superior to 330/30

It also would be almost out of reach for VM, VM could probably surpass 30 with some effort on bonding upstreams, but 100mbit upload would be a different story.

I agree there.

Ironically, those ISPs purchasing WBMC capacity from BT wholesale do so at symmetric volumes. No strange treatment on *that* side.
