Do I need serial cable ?
On all my routers I have tsu/dsu ports which I assume will take rj45 lines ? Maybe one pinned out to be a t1 line ?
Anyways I don't really have anymore time or budget to get more wics ...
What exactly does the serial connection teach anyways ...and can I substitute any lab I read serial connection for tsu /dsu?
When I show interfaces it shows as a serial connection but it looks like an Ethernet jack .
