that is cool, I wasn't expecting it in October, just by the end of the year. My birthday is November 10th so any time around then would be cool ;)

Yes, Virgin Media is deliberately holding your upgrade to give it to you on your birthday.

Just been looking at the plans to start implementing remote phy come the start of 2017.

As always, not my area of expertise but I am becoming more involved in what happens between the CMTS and the Core Routers.

Cool. Will improve plant performance and allow more use of WDM to lower fibre count.

Can I get an ELI5 what remote phy is? (Before qas answers, I already looked at the Cisco paper and frankly I'm none the wiser).

According to 2 seconds on Google:

Quote:
Remote PHY refers to the technique of moving the PHY circuit out of a device such as a CCAP and putting the PHY circuit at the end of a network. Remote PHY builds upon the work started with Modular CMTS (M-CMTS) and Modular Headend Architecture (MHA) at CableLabs.
Tut, obviously...

Now for the obligatory "which year is that". For the last round my area should have been done Aug 14 finally done in March 15.

It basically takes part of the line card customers connect to and puts it out in the field. The fibre link between node and hubsite goes from analogue to all digital.

The remote PHY receives 1s and 0s from the hub site, across the fibre link, which it turns into RF for the cable modems and sends down the coax, and it converts RF arriving on the coax from the modems into 1s and 0s to go into the upstream laser.

Has anyone ever heard of having multiple nodes per street when takeup is really high? or do VM have node sizes that have a minimum size that exceeds that?

I haven't specifically though I know there are some very small nodes in the field.

There's no technical reason why it couldn't be done.

Makes a bit more sense, thank you :)

There's plenty of instances where two properties next to each other on the same street, with the same post code, are on different nodes. Internally, although Virgin will put messages on the website or IVR saying what post codes are affected by issues, they actually track them via an internal node code, like CCC0 1234, for this very reason.

It's why it's usually pointless checking with your neighbour if their connection is all right or not, because nothing is guaranteed.

I think he's asking about nodal areas being so small that a single street has 2 of them all to itself rather than a post code being split across 2 nodes, which can and does happen and is entirely dependent on how the area was built originally.

I've been told that there are student areas where there's fibre basically to the tap as usage is huge, uptake high, and all the houses are HMOs.

Simple as that then
