The EU BEREC guidelines regarding terminal equipment are in relation to provision of an �internet access service�, which is technically not something that Openreach sells to CPs, it purely provides an access service from the customer premise to the handover point of the nearest fibre serving exchange. So that moves the liability onto your ISP who are providing the IAS, however given their contract with OR mandates the MCT process they are somewhat hamstrung in rectifying if OR decide that it is causing issues.

There is also reference to an �objective technological necessity� to mandate obligatory equipment. Given that OR have had issues in the past with uncertified devices causing issues with their DSLAMs (eg the notorious Asus DSL-AC68U) and monitoring systems I don�t think it is as cut and dry as MCT equals a direct contravention. I can�t see a national regulator raising a case where the user connects a device which fails to meet the published technical specification (which a lot of devices do not adhere 100%, especially in the OAM fault diagnosis space), impairs access for other users who are using compliant devices and is then cut off. Given that reporting details on CPE model/manufacturer/firmware to the DSLAM is part of the SIN spec, it is quite easy for OR to determine which devices are and are not compliant.

I think you are reading more in to the "single market" than is required.

Hi Alucidnation, info about my experiences testing various modem to my 900 meter away ECI cabinet. I tried to do tests as scientifically as possible but by the very nature of line noise which can be there one moment and not the next means one has to make a best guess at the results by averaging over several weeks and turning modem on and off when swapping causes my line to slow down by going into interleaved mode. Interleaving takes 3-5 weeks to go. When I first got FTTC around March 2013 about 38down/7.5up Mbits now six years later around 31down/7up Mbits. Even with same modem I've watch the line gradually slow down.

I've tested:
BT's standard supplied modem in 2013,
Plusnet Hub One,
Netgear D7000 version 1,
Draytek Vigor 130

The worst was Netgear router D7000 v1, I found out it uses the Broadcom chip which is probably better suited to Huawei cabs.

Next worst, BT's standard modem, I guess because it designed several years before all the other modems.

Joint best modems: Draytek Vigor 130 and Plusnet Hub One. The Draytek has slightly better up speeds. The Plusnet has slightly better down speeds.

I mainly use Draytek as it gives all the diagnostic details plus better up speed. The Plusnet is all locked down.

BTW did you use the same modem cable as the engineer? So many standard supplied modem cables are low quality. You want to use Cat5e or better cable and have as short as possible and at least 3 inches away from mains power.

OK,

Got up this morning to these...

Hi guys,

Just to bring this to a close, engineer did a lift and shift to a different card and so far all seems good.

Sync back to around 69 with greatly reduced errors although there are still a reasonable amount.

Not enough to alter fly dlm though.
