How many customers on a 10mb backhaul

How many customers could you run on a 10mb backhaul. I know it depends on the type of customers. I am looking for a general idea. We have around 200 customers on a 10mb backhaul (this is our pipe to the internet). Their is very little bandwith management if any at all on most of the 200 customers.

Thanks for the help

Our 20M BH finally hit the wall at around 250. Most of these are business customers.

I’d suggest using Cacti or MRTG so you know when its time to upgrade
