I do like the fact that FTTC 80/20 is sold as 76/19 but in fact it's 74/18...
modems don't sync at more than 79999/19999 anymore... and don't test past 74/18
So customers do get confused with the speeds....
For instance a provider tried to tell one of my folks that they would get 2.6mbps on there ADSL line but there was a fault, the provider then changed their mind and said the line could only do 1.2mbps....
However some changes where made and got the line to sync at 2600kbps... this barely gave 2mbps throughput.... they said they didn't have to as the modem synced at 2600kbps..
After getting the fault on the line completely fixed the line synced at nearly 4mbps giving throughput of 3+ mbps which was suitable...
So I think its now time to start guaranteeing throughput and not sync!
