I think you can do Distributed Multi-Link PPP on a 7500 and support up to 16
T1s (8 on a VIP2-40, and 16 on a VIP2-50 with 4+MB of RAM)

Subject: Re: [nsp] Multiple T1s versus MLPPP
The router won't balance more than 6 parallel paths I believe, so
the only real option is MPPP. I tested this a few weeks ago when we had
a customer situation come up that might warrant doing this. I could
only test 6 parallel paths vs. a 6 circuit MPPP bundle. In my tests, it
showed the 6 load-balanced T1s to be about 4-5% faster than the MPPP
bundle. The 8 T1 MPPP bundle was definitely faster than the 6
load-balanced T1s however. These tests were done on two 7206VXRs
(NPE300) with PA-MC-8T1s connected back to back. The CPU usage
difference between MPPP and load-balanced was perhaps 1-2%.
I'm pretty sure the max you can do is 8 in one bundle, but don't quote
me on that. I believe on the 10000 you can do 10 in a single bundle,
but I doubt you are using a 10000.
