[c-nsp] 7600 line card comparison

[christian.macnevin at uk.bnpparibas.com]

Thanks for the reply. We have quite an investment in 75s and 72s right 
now, so the FlexWANs might
be for us. I'll need to trawl through cisco works to find out what cards 
we have deployed, I guess.

My colleague tells me the FlexWAN cards are cheap on ebay right now, which 
sounds as though people might have
decided they weren't the way to go after all and moved to one of the other 
alternatives. That ring true with anyone?

SIP/SPA is the way to go.

Many of the OSMs are being phased out by SPAs.  You can get similar
per-blade densities, somewhat lower per-port cost, and the capability
for mixed interfaces on a given slot.  However, SIPs aren't fully
caught up to the OSMs  - you can't get every imaginable interface in
SPA form (yet).

The flexwan stuff is really for someone who has pile of 7200/7301 PAs
and wants to re-use them in the 7600.  But the per-port cost is higher
(than SIP) and per-blade densities are lower.
