It you're referring to the Belkin N1, yes, it's an N router. Whether it is equivalent in performance to an N router you can buy today is another matter. Belkin isn't that great with updates.
If it gives you a link rate of 130 Mbps with an N client in 20 MHz bandwidth mode and 270/300 Mbps in 20/40 (auto) bandwidth mode, then it's N.
