so if your running just ppp encapsulation (dedicated T1), then you have to have a separate interface on your router for every site you connect to<br />
<br />
on the other hand, if you are running frame rely, you can have multiple VCs per one interface ( a more cost effective solution)

If you have a dedicated T1 to another site, as well as a T1 to your internet provider.......do you have to have 2 separate interfaces on your router?

Easy WAN question

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.
