A recent meeting between ISPs has revealed that Openreach expect their new 330Mbps capable G.fast ultrafast hybrid fibre broadband technology to cover 2.2 million UK premises by 31st March 2019 (currently c.1 million) and they’re aiming to trial a new self-install solution later in 2018 (i.e. no engineer required).

The G.fast technology works in a roughly similar way to the existing VDSL2 based Fibre-to-the-Cabinet (FTTC) service. Essentially a fibre optic cable is run to your local PCP Street Cabinet, which is then fitted with an extension “pod” (right side of cabinet) that houses the G.fast line cards (this can handle up to 48 ports, but it should eventually manage 96). After that the G.fast service reaches your home via the existing copper line.

At present the only way for end-users to get the service is via a managed engineer installation, which requires them to enter your home and plug everything in for you (the Master Socket may also be upgraded to an NTE5C + new faceplate). This is actually quite handy because engineers can often spot and resolve issues that might otherwise negatively impact your service performance.

Initially most of the installs will involve a two box solution, which means that a dedicated modem (Huawei MT992) will be used to handle the G.fast side and then you can plug your own kit or the ISP’s router into that in order to distribute the broadband connection.

When it says G.fast line cards can handle up to 48 ports, does that mean only 48 people can order G.fast? That seems extremely low, even at 96 ports when compared to 500+ connections to a cabinet. If that is the case then OR think its an accepted margin that only one fifth of customers can access G.fast per cabinet?

No wonder they didn't do G.fast to the pole as probably more people would have ordered it and free ports would have quickly run out.

I don’t know anything about it but I just assumed that with “to the pole” there would be a modem on the pole. So in that case no electronics in a cab and no limitations on dslam ports in a cab? How does it work?

I honestly don't understand how they thought that the idea of investing in a rollout of G.fast at the cabinet was great. I imagine 48 (later to be 96) will be ample capacity given not many will be able to benefit from the service.

I'm quite surprised my recent G.fast installation was an  "Engineer install."

All he did was replace a perfectly functional master socket with the latest NTE5C and supply a modem...

Mind you, with it being an engineer install I can quote the clean line estimates to the ISP when the line synch rate doesn't meet expectations  :cool:

Can you tell us what it is like now browni? And what model of modem did they supply?

The Modem is an Huawei MT992 but I am now using my Asus DSL-AC88U running a debug version of it's firmware for telnet access.

Live stats here!

Currently It's synching below the handback threshold speed so am now waiting on an SFI visit.

Regarding the software at work there, a tweak would be just to detect G.Fast and then always report (override) that vectoring is turned on. It’s an obligatory feature with G.Fast isn’t it?

I wonder what the story is with G.INP ?

Does it really say 220 Mbps? Unbelievable.

How much should BT be charging AA (my ISP) and thus me for 2.5 Mbps then?

I thought vectoring was necessary and have raised the question with my ISP.

This what I get if I query the vectoring status
Code: [Select]
bcm_xdslctl: ADSL driver and PHY status
Status: Showtime
Last Retrain Reason:    2000
Last initialization procedure status:   0
Max:    Upstream rate = 36788 Kbps, Downstream rate = 220039 Kbps
Bearer: 0, Upstream rate = 36788 Kbps, Downstream rate = 220328 Kbps

Currently not in VDSL modulation --vectoring is only for VDSL mode

I assume that that is just a bug in the ui. It perhaps looks at some variable, sees the value is ≠ VDSL2 and therefore assumes it is ADSL so deduction “no vectoring”. Could make sense if it is just old code and they forgot to rework it. Just speculation on my part, obviously.

Is it safe to assume anything with G.fast?

I'll raise this with Asus.

Supplying corrections to the above:
  • A "G.Fast" side-pod can be attached to either side of the PCP. The unit may also be deployed in a small dedicated cabinet if neither side of the PCP can be used for mounting a "G.Fast" pod.
  • It is 48 ports per line-card and four line-cards per Huawei unit. The density can be increased to 96 ports per line-card.

Are you sure about that?

Has that been approved, by Openreach, for use on its G.9700/G.9701 service? Have you been authorised to use it in place of the Huawei MT992? If either answer is "no", then expect the SFI engineering report to state that the problem is self-inflicted and your ISP to be charged for the visit.

The specifications can be seen in the relevant ITU-T documents: G.9700 and G.9701

As sure as I can be. But I would appreciate any corrections (in private, if necessary).

I think it's 48 (later 96) total ports per G.fast pod, not per line card.
