sbiddle: The UFB GPON deployments in NZ are all Ethernet based, not ATM.

ATM is only used by Chorus for legacy DSLAMs and BUBA connection, their core network and ISAMs are all Ethernet.







Oh right. I didn't know that was possible since I've only seen GPON information using ATM. Which ISAMs are the LFCs using?

ISAM is a Alcatel Lucent product name for the 7302 ISAM their next generation DSLAM that Chorus are deploying.

UFF and Enable are deploying the Huawei OLTs but have very different BSS portals for provisioning.

Northpower are deploying the Ericsson OLTs 

All of them have their pluses and minuses.... I'll reserve my view as to how well each of them are doing to over beers covered under frieNDA.

According to the product pages, all the ISAMs except the Ericsson ones are 10G GPON ready, so I'm guessing LFCs planned an easy migration to 10G GPON then?

Are the 7302's used for UFB? Thought they were only for EUBA, VDSL, HSNS, (xDSL) based services?

ISAMs are used for xDSL - therefore none of the LFCs are deploying them because they don't do xDSL.

You'd have to have a pretty backwards view of the world to want to be deploying GPON with an ATM core, talk about building something that's crippled from day one.

I never said I wanted anyone to deploy GPON with an ATM core, I am simply asking questions since I don't know what goes on behind the scenes, I'm a software engineer not a network engineer, I don't know the ins and outs of the technology behind UFB but I would like to find out.

I've heard of people playing with 10 GPON in NZ but the equipment is so expensive that you would only think of using it in a MDU.

I was surprised at the equipment that I looked at that it has mainly FE ports and very little GE port support. I expect that will change soon though.

Until the price drops dramatically, I don't see it used very much.

The 7302 is the same physical ISAM element that Chorus have deployed for EUBA/WVS/HSNS services as part of their cabinetisation project however they are deploying all new 7302's for the UFB project that sit in the Exchanges vs the cabinets that are out on the roadside. The two networks a physically and logically separate. So for example if you wanted to order a copper service for one house and a UFB service for the house next door then Chorus would deliver it over two separate handovers to the RSP.

so, are you saying chorus are going to start providing copper services, over fiber where available? or have i miss understood what you have said?

The way I am interpreting it is that some of the equipment used for copper is similar to the equipment used for fibre.

He's saying there are two networks, one for copper and one for UFB but they both happen to use 7302s just at different locations. I don't see copper services being provided over UFB as that would counter productive.

see, this is why i queried it.


it didnt sound right (why offer a copper product, when you have UFB there afterall.), but then every time i read it thats all that came to mind.

all things considered, i do think i got the wrong end of the stick there!

Same network element purchased from Alcatel but used in a completely different network.

Unless I am wrong Chorus don't ever plan to offer UFB services on their Copper ISAMs, and vice versa.

The fact the networks are built on the same equipment (7302's and 7450's) doesn't change the fact they are two completely separate networks managed and provisioned using separate upstream systems. The 7302's just happen to have different line cards in them one for DSL and the other GPON is the only physical difference. The logical and software versions couldn't be more different.

Did anyone see this? Telecom wants to offer 1000/500 nationwide.
