Depends on what you're using it for. ATM adapters work fine in 75xx's,
but if you're planning on DSL termination, especially with bridging
or otherwise involving lots of PVC's and sub-interfaces, you really
don't want it on your 7500. An RSP4 or RSP8 is a good thing to have
if you want to try that, otherwise a 7206 is a good front end, and
recent IOS deals with some of the performance/scaling issues.
Also, if you're going the 7500 route, the AIP will work but is a
fairly limited interface, it supports only a limited number/range
of PVC's and doesn't support CBIT-PLCP framing. The PA-A3 is the
good guy interface, but requires a dedicated VIP-2/20-40 or VIP2/50,
in a 7206 you'd want a NPE-200/250/300 to avoid running out of SRAM.
Any of you Cisco folks know why IRB is broken or not supported on
the PA-A2 aka PA-ATM-CES in 12.1T-land?
