Mark,

Which ASR920 model do you use, and do they all operate the same? Based on
the model comparison there is not much difference between them, but it does
look like the ASR-920-12SZ-IM has a Quad-core 1.2 GHz where the rest of the
models have a Dual-core 1 GHz.

Looks like the ASR-920-12SZ-IM has the ability to add a 1 port 10G IM card
making 5 10G ports total. The ASR-920-24SZ-IM has the ability to support
the 2 port 10G IM card, for a total of 6 10G ports. Kind of surprising
since the ASR-920-12SZ-IM has the faster processor.  Both the
ASR-920-24SZ-IM and ASR-920-12SZ-IM have the same list price of $7,000 from
Cisco.
