I can also confirm two.

However, if you are looking at additional links for "performance", you could work around the issue by working with your ISP's.

For example, we have two ISP's providing two T1's each. They simply provide a managed ethernet hand off (this way the router hardware is their support and requires them to provide sufficient hardware for growth, as we've planned the possiblity to add up to 6 T1's per provider, after that, they'll require we purchase a fiber loop and metroethernet, which is costly since we are outside of any of the current metro loops. Remember it's all about location, location, location).

So we have 4 T1's that are presented as two ISP's to our Gateway.
