[Internet] New 50/10/175 FTTN plan

Would the new 50/10/175 FTTN plan use the exact same technology as the older 25/10 plan?

Would it use the same VDSL modem as 25/10 (with mandatory rental from Bell)?

If 25M DL works at a location, should 50M work, or might the line condition still restrict the DL speed to less than 50M?

Pricing Details, and FEATURES tab mention minimum speeds... "Actual speeds will vary depending on the distance between the customer’s modem and switching equipment from Bell : min. 46 Mbps and max. 50 Mbps down speeds; Min. 9 Mbps and max.10 Mbps up speeds."

Pretty good 'Minimum' speeds there, but the Overview and Specifications sections do not specify any minimum figures. Confusing website specs, as usual.

Just wondering about the technical aspects of this new plan; not the "value"!

The difference is the VDSL2 profiles. 50/10 is delivered using profile 17a, which uses 17.664 MHz of spectrum to deliver 100Mb/s max downstream, compared to the current 25/10 plans using profile 12a, 12 MHz of spectrum to deliver maximum 68Mb/s downstream.

In case you ask the question "why couldn't they use 12a for both", it's that these maximum downstream values could only realistically be experienced with extremely short cable lengths; more spectrum is needed to deliver the higher speeds over longer distances.

This is also the reason 50/10 is only offered in very specific areas. Even though I'm 60m loop length from my JWI, I can't get 50/10 because I am served by an old Lucent Stinger DSLAM and not the newer Alcatel-Lucent 7330 DSLAM.

I'm connected to the Alcatel Lucent 7130, able to get 50/10.

Some JWI have both if lucky.

But I'm pretty sure they will offer or offer 50/10 on Stingers... the profile is there.

There is no 7130 DSLAM. You're probably thinking of the ALU 7130 Cellpipe modem.

I've noticed a lot of downtown Toronto JWIs have both during my strolls, but only 1/17 JWIs around here (NW Oakville) have a 7330 (and it's not the one I'm on, unfortunately). Is there realistically any chance of Bell switching the Stingers to 17a? I know they've had enough problems with them already; is the Ikanos chipset reliable enough to do 17a?

I think the card itself is not 17a compatible... but either way, the profiles is there on 12a. So I don't see why they would block it if the customer is near the SLAM.

My attainable is high enough to support 50/10 with a bit of buffer, but the Bell site says I only qualify for 25/10. So either they're taking some time to update that, or they are indeed refusing.

Same here, but I'm assuming I only qualify for 25/10 because I'm connected to a Stinger.

50 is available on Stinger depending on attainable...

50 with IPTV is not.
