So a fiber cut that hits a feeder between the Central office and other areas can easily cause Dark Zones (no Internet, no mobile (if your mobile provider is using GPON backhaul)).

 

 

Yeah - but surely each of their aggregation points (not sure on the correct terminology for where the GPON switches live) should have diversity for the backhaul...

 

I've put a lot of thought into ISP selection and which ISPs have redundant paths but always assumed Enable would build some level of this into their network.

 

We're switching our secondary dedicated fibre connection to GPON at work shortly as consider this risk to be fairly low given the primary is dedicated and has physical path/PoP diversity.

 

 

 

 

More to the point, that so many aggregation points were reliant on one single cable. Based on their updates - three - Rangiora, Kaiapoi & St Albans. But also a mention of an outage in Sydenham indicating four or more.

 

I can sort of understand a a single central office being reliant on a single cable given the architecture and price point, but the fact that a single cable can bring down 1/3 to 1/2 of Greater Christchurch is pretty concerning.

 

It's kinda a blessing that uptake is relatively low at the moment - give it 2-3 years and the impact would have been much greater.

Didn't Telecom have an issue with the Riccarton exchange recently cutting off way more DSL users?

Why? So it could be half finished now and affect way fewer people?

Come on, most people are getting connected in 2019.  Chorus are doing the best they can!

 

On a more serious note, Auckland has a lot better VDSL coverage than a lot of other centres.  Which is good enough for most users.  That said  it seems crazy that they started in VDSL abundant Remuera..

Enable are really good to deal with actually. Installs are getting done fairly quickly.

 

Also, provider churns are handled really well too. Rather than just a hot cut-over they liven up 'port 2' on the ONT so as long as the CPE is set up properly, literally anyone can shift the cable from port 1 to port 2.

Yes everyone but Chorus seem to be able to handle multiple RSP's on a single ONT, Why Chorus haven't been taken to task on it is beyond me. So much of the BitStream spec's are built around Chorus's old kit (like mac limits)





Most problems are the result of previous solutions...

All comment's I make are my own personal opinion and do not in any way, shape or form reflect the views of current or former employers unless specifically stated

Enable does do some good things but there are two big problem areas.

 

Enable takes a month to activate an intact ONT. One month, just to push a few button. Whereas Chorus can do it next business day.

 

Last time I called Enable, it took them half an hour to answer the phone. Chorus almost always answers on the first ring.

Chorus has been able to do this for more than a year now.
