7200, 7500, 7400, or anything else that will take a 12.0S, 12.2S, or 12.4 IOS and a PA-POS-OC3SMx (where x is L or I depending upon optics reach). If the service provider requires APS protection on those circuits you need two of them. I have a pair of 7401ASR's with two PA-POS-OC3SMI's doing APS, and that's a quite interesting thing. If you think you need more ports than 7401 provides (two GigE/FastE combo ports) then 7200 is good choice; if you really want bargain basement prices get somebody's castoff 7505 or 7507. > 2) On the central site, have STM-16 SDH connection; some channeling is > required, so each remote STM-1 is a sub-interface. Older 12000 running 12.0S and a channelized OC48 linecard. The OC48 channelized cards should work with any of the fabrics available for 12000, and might even work in 12008 or 12012 with a full fabric. 12012's are available cheap on eBay, but you might get a good ROI for something that requires less power and rackspace by spending more up front for a low-end 7600 or even 1000, and the 7600 and 10000 will give you more edge features than 12000. Not having set up the channelized OCx stuff, I'm not sure which software features you would need, sorry. APS would still require two chassis; there is a single router APS option, but only with specific linecards and specific chassis. -- Lamar Owen Chief Information Officer Pisgah Astronomical Research Institute 1 PARI Drive Rosman, NC 28772 http://www.pari.edu _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
