We have an old Cisco 1760 router which installed 2 T1 WAN card and we're going to replace it with a new Cisco 2821router. Can we still use the same WAN card at new router or have to get new card?<br />
thanks!

Can both Cisco 1760 and 2821 use same WAN  (T1) card?

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
