Meanwhile on Zen's FTTC my FritzBox is connected using VLAN 101 and a VCI of 38.

That VCI setting is unnecessary and is only required on ADSL.

That will be because I bought my own FritzBox when I upgraded from ADSL to FTTC and I just copied the settings over from the Technicolor! I'll delete it, thanks.

Devil's advocate says next week there will be some major interference or disruption to your connection, and without those settings your modem/router won't be able to negotiate with the DSLAM down to ADSLx. 👻

Is that really a thing? I thought FTTC and ADSL were different fish in different kettles, even if in the same kitchen.

Importantly, I forgot the thread was about FTTP where clearly my reply was not applicable. It was specifically referring to ADSL mentioned in:

I've never seen any reports of an FTTC connection dropping VDSL2 down to ADSLx, but AIUI the DSLAMs in the FTTC cabinet could in theory do that.

However, whether or not it can happen will depend entirely on the options enabled by Openreach in the related cabinet modem.

Compare with how you could set the options in your modem under ADSLx to cater for excess noise bursts, allowing it to connect at lower levels than the highest available at the exchange. Many of us even forced lower levels in pursuit of faster connections on ADSL2 or even ADSL versus ADSL2+ on longer lines.

I wonder if anyone on very slow FTTC has tried setting their modem/router down to ADSL2+, to obtain the benefit of the lower attenuation from the cabinet compared to their previous exchange connection. I have a feeling it is indeed ruled out in the cabinet modems.

We are now a few years on since this thread was active but it raises a question that will be asked more often as more people have FTTP installed.
The VLAN on the Technicolor DGA4134 supplied with my Zen/City Fibre installation last week was 911.
The same VLAN works with my Asus DSL-AX82U router.

I've been advised by Zen that 911 is the setting for Cutyfibre - it works on 3 different routers *Frtiz, Technicolor, Draytek).

VCIs aren't a thing on FTTC. Can be set to anything, doesn't matter.

The cabinets are expressly configured not to drop down to ADSL. They support VDSL 2, profile 17a only, bar trials.

The VCI is about ATM rather than ADSL specifically. Virtual Circuit ID, half of the VPI/VCI pair that forms an ATM PVC / permanent virtual circuit.

PPPoE uses VLANs, sometimes stacked, instead.

Thanks for confirming my suspicion Carl. It's a pity though. ADSL2+ could gain from local DSLAMs. Could even perhaps take some slow areas above 10Mbps.

I don't quite understand why you are stating it works on 3 different routers, it has to work whatever router you are using as it is a parameter on the FTTP network, all user connections have to use the correct VLAN ID. I quite like the name Cutyfibre though.
