FTTP - line profile?


[link to this post]
 
Just out of interest I was wondering if you still get a line profile with FTTP?

I cant imagine there would be any mechanism for something to degrade the service on the line ie interference, so maybe there is no need for the system that provides the ip profile?

U believe that FTTP (fiber on demand) is unfettered No DLM , but it still might have the ip profile But that would /should never change

given how BTw etc. works there probably is still a ip profile, just it wont change unless you change product.

BT Infinity 2 Since Dec 2012 - Estimate 65.9/20 - Attainable peak 110/36 - Current Sync 71/20

Yes. FTTP is delivered in the exact same way as FTTC as far as BT Wholesale go.

You do, so the right resources are allocated to your circuit as it transits the ether to your ISP.

So ~ 96790 on a 100Mbps connection.

Now you have me confused by your own replies smile.

I did think before your previous post that FTTP 100 delivered data rates of 100Mbps. Then you said, yes there is an IP Profile.

As the IP Profile for FTTC is ~ 96.79%, I conclude you meant it would be the same for FTTP, even though there is no DLM operating, viz:-
Please note the speed associated with FTTC is determined dynamically by the VDSL line rate.
Please note that there is no DLM on FTTP services.


(Bearing in mind what the "D" stands for).

The PIR value doesn't mean a lot to me given that note. I find the following quite interesting:-
FTTP has recently been added to the Wholesale Broadband Connect (WBC) portfolio to offer downstream speeds of up to 110Mb/s with even higher download speeds planned.
So when you say there is IP Profiling on FTTP, are you in effect saying the PIR acts as an IP Profile by reducing the 110MBps connection speed to 100Mbps throughput?

I'm stuck tongue.

From what I can read the FTTP product discussed there is the old 100Mb downstream, 2Mb upstream product.

I'm unsure why there being no DLM would affect a BRAS profile being in place.

The lack of anything rate adaptive along with that FTTP is policed downstream by an OLT ensures that the normal reason for it to be there, to ensure that BT's network isn't pushing too much data, doesn't apply.

It's there for capacity planning and reporting purposes only from what I can gather. The GEA products are pretty much identical in their implementation as far as Wholesale go.

I'm not sure whether Openreach report anything back to the operator from the FTTP network in terms of connected rate but it could easily be done statically by hard setting a RADIUS parameter if not.
