Wow. Looks like didn't know as much as I thought. I've never heard of CCNT before and always thought that RCDD was the acceditation to show one's worth in IT system design.
I would have thought that Cisco and MS were only relevant to those specific companies' products. So a certification with one of them would lock you into using only their products.
RCDD is issued by BICSI and geared to cable infrastructure layout and design. The only requirement is you buy a book, study it, and take a test for a fee. Basically they work for and take the design of archetects, engineers, and network mangers, and lay it out on paper for being implemented. There is nothing wrong with that, but I get the impression from the OP he is looking for something more than that. So sorry if I offended anyone.
Cisco Certification is a Standard and not a product per se. CISCO sets the standard for all network transmission and all product manufactures follow the standard. Yes Cisco make the routers, switches, etc but they were first and set the network protocols all must follow.
MS is both a technolgy and a product, depends on which certification we are talking about
