Dte Cable

serial DCE and DTE?

What is the difference between the two serial cables?
So in a network with several routers, i only need one DCE cable at the root of the network?

DCE = Data Connection Equipment
DTE = Data Terminal Equipment

basically the DCE sends out the syncronization (heartbeat) for the clock and the DTE listens for it and paces itself accordingly

EDIT:
If you have 2 routers connected via serial connection one must have the DCE cable... If it's the central router that is okay.. just make sure you set the clockrate on each interface that connects to another router via serial. check out the link below.. I believe you have to use both cables. the DCE cable on the router w/ the clockrate set, and the DTE cable on the other router. (for each router, so if you have 4 routers connecting to a central router you will need 4 cables configured this way)

However, usually serial connections are only used for a wan connection. The second link below also has a good explanation
