[AusNOG] NBN FTTN And Migrations and End User Equipment

[paul+ausnog at oxygennetworks.com.au]

Matt is spot on, having done the certification in the NBN lab I Can tell you that as long as you satisfy the tests they don’t care, it’s an access seeker certification to say you know how to do it and you have passed their tests, once you do that you can do what you want as long as it works and technically complies.

Hi Matt,
 
This is different to what I understood, which I had gleaned from 3 separate sources:
 
1. The NBN guide on this stuff (section 7)
http://www.nbnco.com.au/content/dam/nbnco2/documents/sfaa-wba2-product-catalogue-nebs-product-tech-spec-fttb-fttn_20150824-to-FTTN-launch.pdf
2. The guide from our wholesale provider, which mirrors the above section in NBNCo doco
3. Whirlpool, which I realise is tenuous, but there is a lot of discussion on this particular part of NBN in various threads.
 
>From the NBN doc:
 
"NBN Co encourages but does not require Customer to register VDSL2 Equipment to be used with the NEBS supplied by means of the NBN Co FTTB Network. or the NBN Co FTTN Network"
 
So now I don't know. Certainly internally we are following the process given by our wholesale provider which is to get our chosen CPE certified at the NBN test facility and go from there.
 
In regard to how the work is done to migrate from ADSL (existing) to VDSL (NBN) my understanding was that during the Node installation phase an extra copper loop was installed that goes from pillar to Node and then back to pillar, effectively providing a "pass through" connection that goes through the Node now for existing ADSL services (there were outages on existing ADSL while this was being jumpered). When an NBN service is ordered on an existing line the loop that returns to the pillar from the Node is disconnected and the copper is jumpered to the Node DSLAM.
 
I'm still not certain if voice pass through (to exchange) is being supported, but if this is, then the copper return back to pillar is left connected, but with a filter on it so that DSL frequencies do not go past the Node.
 
 
regards,
Tony.

Certification applies to the access seeker, not the CPE. If you choose to initially certify 1 CPE you do not need to recertify when you want to introduce a new CPE to the mix. If you want to use NBN’s VDSL modems from their lab for your certification and then use a tin can and string in the real world, that’s up to you. Repeat after me. The CPE is not under certification, the access seeker is. 
 
This is great if the entity ordering the AVC is the entity that was certified at NBN’s facility. The disconnect comes when the “access seeker” that was certified by NBN for FTTN in the lab (Eg a wholesaler) is not the entity that is ultimately driving the order or providing the EU with a CPE (Eg downstream RSP ) . In this scenario communication as to what CPEs would be supported is essential.

VDSL modem's need to be certified and from what I've heard from NBN and the trials, each ISP is required to test and prove the VDSL modem they intend on supply so I don't think this is going to be a case of 'Buy the modem that is right for the job'.
 
I've even heard of the MSAN shutting down the VDSL port based on MAC address during the trial if you tried to use a non Telstra supplied CPE.
