thanks for your replies anthony, yes you are correct, its surely 10GE (6704 or SPA being the question), and not SDH/OC192
I currently have 6704 links to my internal core working just fine, but those are LAN links as intended by design of the card :) the choice and suitability of the interface to the upstream carrier is the question here, as the cost of a 10G interface on the already existing 6704 card is low (basically the cost of the XENPAK), compared to the cost of a SIP/ES20 which is $$$ then again if there are serious issues with using the LAN port for an upstream, it _may_ perhaps justify the price if we gain on stability, etc.. would be interesting to know the _technical_ reasons why cisco frown at this. thanks anton _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
