Chorus do offer LAGs and I am fairly sure all other LFCs also offer (or will be offering) LAGs. Enable and UFF do, Northpower is doing it shortly from my understanding

The Chorus LAGs are offered off the same chassis so it won't protect against chassis failure on the LFC side but depending on how you connect from the LFC to your BNG there is the possibility for diverse paths between the two. What about BNG failure on the ISP side?

The more common scenario I have seen is there isn't much path diversity from the OLTs to the aggregation switches on the LFC side. So all RSP/ISPs are at the mercy of contractors digging through those cables and the whole OLT being taken out.

And there definitively isn't any diversity from the GPON port to the splitter.

Chorus put their OLTs in the exchanges, I'm fairly sure Northpower do the same putting their OLTs in Sub-stations and have their splitters up on the polls.��

There is no redundancy / diversity options on Copper. So it's no worse than the current situation with Chorus BUBA/EUBA/WVS handovers.

As far as I know Chorus doesn���t have a diverse handover service for NGA (UFB) generally available yet.

Ultra Fast Fibre offered a number of diverse handover options initially. We took up the option which would see Bitstream 2 services ���dual-bound��� to handover ports at diverse POIs. Operationally it didn���t work out and lead to ongoing provisioning issues, and we continually ended up with services only bound to a single handover port, provisioning delays and faults, etc. We ended up giving up and relinquishing our multiple handover ports in Hamilton and moving back to a single HOP, as it caused more trouble than it was worth. A bad experience all-round and a fairly disappointing outcome in the end.

I���ve been told that this topic has been or is being discussed in the TCF���s UFB Ethernet Access Service working party, but I don���t know the details.��

Cheers,

This isn���t the place for home Internet questions, you might want to try geek zone, but;

- Last I heard, Chorus weren���t doing diverse handovers for UFB services, but that it was being tested or something. I don���t know if anyone has implemented it if it has been tested. Perhaps we can bring this back in to the realm of network operators by asking if anyone knows about this?

- Get a second UFB connection with a different ISP.

Hi

I've had UFB at home for two years now.�� I'm on to my second ISP.�� ISP #1 had an 8 hour outage for all their Whanganui UFB customers due to fault in their backhaul.�� ISP #2 had a 20 hour outage last month for all their Whanganui UFB customers due to a fault in their backhaul (they say Chorus) between here and Palmerston North.

Who provides residential UFB in Whanganui that won't be brought down by a single backhaul fibre fault?�� I realise I'm getting a residential service with essentially no SLA, and that the fibre between me and the interconnect point is a single point of failure.

I'm happy to take off list answers and won't post your answers publicly unless you particularly want me to.
