@ Puppy,

Re FTTC RFS dates, if you'd like to see a real pantomime just quickly scan from here downwards:-

I am no longer excited by a promise of new capacity being available but usually just wait for a report from the EU.

Kind regards,
Walter

Guess we'll have to agree to disagree. I can state from personal experience that if the drop-wire existed at the EU's premises, we classed this as 'In-situ' and there was no 'install' charge. There was no LLU back then, and we were still BT and had the monopoly.

PPS .............. to return to your original gripe of FTTC coming 'too early' for you personally, I can tell you that as of tomorrow, 'VDSL Cab only' engineering tasks are to begin nationwide. In other words, self-install appears to be with us.

Oh good, then that's what's happened here to mine then!

Obviously I can't comment on your experience from 2001, but what I can categorically say, is that when we closed an Installation Task, (before Openreach was formed), we had 3 sections to fill in regarding the wiring details.
The first was a box asking 'Is there evidence that service ahs previously existed ?'. We indicated that there was by way of inputting a '1', or that there wasn't, by way of a '0'.

The next 2 boxes covered Internal Wiring.

If the first box had a '1' in it, the EU got the installation for free as it was classed as 'In-situ'. I can't be any clearer than that I'm afraid. There may well have been sundries such as a 'Connection fee' to cover Frames work and admin, but I reiterate, the 'In-Situ' component of the installation was free.

Regarding your other matter, it begins at 'Pleb level' ( ) tomorrow. The tasks will be rolling out from then.

Gentlefolk,

1.  Has anybody seen any instructions on what types of modems are compatible with BT Wholesale's VDSL offerings to CPs and if so are these to be unlocked so the EU can determine if adequate services are provided ?

2.  Is a CP now entitled to request a DLM reset without an Openreach visit ?

Kind regards,
Walter

Two very good questions, Walter. Alas, I can't answer them only to say that the 'brief' we got was that CP's were working on ways of combining modem and router, so that there was just the one item to plug in. I would guess that development stages of this mythical beast, ensure it is left 'open' to EU's prying eyes, as opposed to 'locked down' ?? Other than that, I have no idea at all !!

Regarding the FTTC 'Recalc' (reset), I shall certainly keep my eyes and ears open around this subject, Walter. If I find anything out, I shall give feedback anon.

Is it possible that the imminent arrival of the PCP-only connection was preceeded by some behind-the-scenes changes to the profile banding that (some) people believe has been happening only very recently?

3. CPE REQUIREMENTS ... 20
3.1 SCOPE ... 20
3.2 REQUIREMENTS... 20
3.2.1 Physical Connection ... 20
3.2.2 VDSL2 Layer... 21
3.2.3 Ethernet Layer ... 24
3.2.4 WAN VLAN Layer ... 24
3.2.5 Ethernet OAM... 25
3.2.6 CPE VDSL2 Filter Requirements... 26
3.2.7 Supplementary Information... 28

[Edit] for example, a properly configured HG622 is a 'one-box' VDSL modem/router (there are many others), and with the current BTOR SSFP would be compliant with the Centralised filtering requirements of 3.2.6.1, and with a Z-350UK filter dongle would be compliant with the Distributed filtering requirements of 3.2.6.2.  Of course the usual concerns will arise wrt star-wired extensions presenting bridged taps. Note that section 3.2.6.3 of the SIN explicitly addresses the bell-wire issue. Otherwise, it would appear that sync reductions from the distributed filtering model are in line with the length of the extension wiring exposed.

Unfortunately, my 'expertise' in FTTC banding is pretty much non-existant, Colin. In my own personal experience though, the 'bandings' have been there since I first started working on FTTC, which is a couple of years now at a guess ??

As engineers, they tend to be used whilst faulting a circuit. Lets say DLM has capped the EU's circuit to 10Meg DS. With our testers plugged in at this speed, errors will be practically zero. So, we request the NGA Helpdesk perform an 'Override' to assist with the faulting. The NGA Helpdesk will look at what the circuits capability has been in recent weeks via RRT, and apply the relevant banding, lets say 'Level 31' which is ...... 29-45Mbps.
Once faulting is completed, the engineer will ring the NGA Helpdesk and request that a 'Recalc' be carried out. This should then put the circuit n an 'Open Profile' of 128Kbps - 80Mbps.

The DLM acts on its 'sampling' every single night (well, early morning from what we were told). I suppose if it sees something it doesn't like, then it may apply a banding ?? I really don't know ??

Thanks BS that's very helpful, as always.
