T1 aggregation and data center gateways

[Tim Sanderson <tims () donet com>]

Currently have T1 aggregation on some Cisco 7206VXR routers. Core switches and data center gateways on a couple of 
Cisco 6509's. Looking for a model that could collapse both functions into just two devices, one being for hardware 
redundancy. Any recommendations on a good L3 switch that is also a good T1 aggregation device? Anyone have any 
experience with the newer Cisco stuff like the ASR 1000/7600/CRS-1?
