OK, this is on my personal blog as you can post comments and ask questions. But basically AAISP are looking at new tariffs.
However, we have a slight difficulty because we have so many choices. I am not sure of the best way to offer simple clear and understandable tariffs which are fair.
Basically, we have three types of line:-
1. 20CN, and these are gradually being moved to 21CN over several years
The lines have different base costs, with 21CN being lowest, 20CN costing maybe 30% more, and BE costing a lot more (about 4 times a 21CN line).
The lines have different usage costs now, and this will be even more the case from January. BE lines are the lowest. From Jan 21CN lines will be around 6 times as much as BE line and 20Cn lines around 15 times as much as BE line.
So we need to dream up tariffs and options that fit and handle people with multiple different types of lines, but are understandable.
For a start, I am thinking we separate line cost and usage. This also helps with min terms on BE lines (6 months) as that could be line cost only with usage stopping when the line is stopped.
However, usage is complicated. Current ideas include :-
1. Charging as now, based on GB, based on time of day, and preset usage levels and excess charging, but different rates for different types of line.
2. Having usage levels, e.g. 1Mb/s committed with bursting but with automatic limiting after an hour or two to ensure usage never averages more than committed rate and so no risk of excess usage charged
3. 95th percentile billing with a base commit level and higher rate over charges.
All are possible, but we don't know what people want to do.
It is also not clear how best to handle bonded lines with say 21CN and BE where the usage is different but we in effect have to commit to 21CN side for the total to allow for BE breaking.
So, I am open to suggestions on this.
Timescales are that we would probably launch BE lines on some sort of new tariffing system in October, but the 20CN/21CN lines on a new tariffing January.
