It�s FTTP no modem required ...

I was just given an install date - no time slot - no phone call or contact before the date - I was actually the first appointment and he was at my door at 8.30am on the specified date.

Latest update from today is that I have an appointment booked for tomorrow morning. I look forward to it.

I sent an email enquiring about PPPoE and IP address details, ideally so I can configure my router so it's ready to connect on the day. Hopefully I'll get those today. Also enquired about how to pay for the service itself, as I can't seem to setup a direct debit (option is unusable on my account) and I don't appear to have an invoice yet.

Cerberus send the invoice day after you've connected.

I see, thanks. Well I have the PPPoE details and IP address details so I'm able to configure my FB2900 ready for the connection to the ONT device tomorrow, assuming the FTTP installation is successful and there are no issues. Fingers crossed..

Woohoo, all done! Engineer was chatty and busy. He was late but I didn't mind that, Openreach were made aware that I was happy with an afternoon slot as long as someone arrived today.

Poor guy has a two hour trip home, presumably the last job of the day too as he didn't finish till about 4:30pm. Took nearly four hours. He had an issue at the end of the installation (red light) but it turned out a bit of rain managed to get on the end of the optic cable at the pole and was rectified easily!



One thing that does astound me however is that Cerberus, or at least on my connection, isn't providing any IPv6 range. Is this something I have to request or is it not supported yet?

Based on posts from forum user 'brookheather': you can go to a website to get a /64 allocation for your WAN link, and then on request they will give you another single /64 (!!) for your LAN side.

That's just mad. Shout and scream until they give you a /48, or at least a /56. Point out the relevant standards - e.g. rfc3177, ripe-690.

Thanks but I don't think that's necessary now, I think after a bit of time or reconfiguring of my FB2900 I've now got an IPv6. It looks like /64 though as you mentioned. But why would I need a /48 or /56, other than because of relevant standards? Sorry if it's a stupid question but surely /64 is enough as that's 18,446,744,073,709,551,616 addresses right?

EDIT: After reading the second ripe mention, I see...

Assigning a /64 or longer prefix does not conform to IPv6 standards and will break functionality in customer LANs. With a single /64, the end customer CPE will have just one possible network on the LAN side and it will not be possible to subnet, assign VLANs, alternative SSIDs, or have several chained routers in the same customer network, etc.

I'll ask Cerberus for a /56 at the very least tomorrow due to this.

I had the following update from Cerberus on Thursday:

�Openreach advise today that they are currently chasing for the OCR exchange estimate to be completed before jointers can return to site. Underground allocator has assigned an engineer to site today to deal with the exchange work, if successful jointer will be assigned later in the week to complete the testing.�

Can anyone here from Openreach explain what an �OCR exchange estimate� is please?

Is it some sort of optical loss or OTDR test? I have asked Cerberus to explain in layman�s terms, but it usually takes a few days to get a reply from them and often my question doesn�t get a straight answer, so looking for some clarity from the eggspurts on here

Did some judicious googling and found some references to OCR in some Cartesian/Ofcom documents:

OCR (Optical Consolidation Rack)
3.41 The OCR is used for the splicing of the OCR Tie Cable into fibre cables for direct connection to the active equipment (in this case, the OLT). The OCR constitutes an efficient alternative to the traditional Optical Distribution Frame (ODF). The OCR is comprised of a few subcomponents, which are listed separately in the 2016 NGA model. The table below lists the subcomponents, as well as typical capacity values. Note that these values will be updated in the next iteration of the 2016 NGA model, following input from CPs.
