FTTC Speed v Loop


[link to this post]
 
High Speed Internet Profiles:

Line Length (max) - Down (Mbps) - Up (Mbps)
300m - 100 - 20
450m - 90 - 20
525m - 80 - 20
600m - 60 - 20
750m - 50 - 20
850m - 40 - 10
1000m - 30 - 8
1200m - 25 - 8
1300m - 18 - 5
1500m - 15 - 3
1700m - 12 - 1
2000m - 7 -1

High Stability profiles (for eVision)
Line Length (max) - Down (Mbps - Fixed) - Up (Mbps - Rate Adaptive)
300m - 85 - 5 to 20
450m - 80 - 5 to 20
525m - 70 - 5 to 20
600m - 60 - 5 to 20
650m - 50 - 5 to 16
750m - 40 - 5 to 16
850m - 34 - 5 to 16
1000m - 28 - 50 to 15
1200m - 20 - 2.5 to 8
1300m - 18 - 2.5 to 7
1500m - 12 - 0.25 to 1
1750m - 10 - 0.25 to 1
2000m - 4 - 0.25 to 1

Poor guys. They don't know what's coming...

However, these figures have been posted onto this board without any context. So... in case anyone else gets the wrong end of the stick, note the following about adslmax's figures:

- They are speed profiles applied by Eircom to their (new) vectored VDSL2 product range. Before they added vectoring, their top profile was 70/20.

The profiles are nothing to do with the UK.

- The profiles are artificial speed limits for each distance, not an indication of how VDSL2 performs with distance (with or without vectoring). They are instead an indication of what distance they expect to get, and still stay on the very stable side.

The profiles are deliberately de-rated from the best-possible speeds - they act like a manual version of DLM.

- In Ireland, you are assigned one of these profiles when you order. They do not run the line as fast as they can from day 1. If you have considerably better attainable speeds and SNR than the prediction, they will try bumping you up a level - but you must phone Eircom to get it to happen.

- We know nothing about the architecture of the access network in Ireland. What gauge wire they use, and what the average D-side length is. We don't know how many pairs tend to be within each cable. We know little to help us cross-reference these speeds into equivalent UK figures.
