Hi all,
can any body help us regarding serial link problem
serial link detals are as follows
Serial0/0/1 is up, line protocol is up
Hardware is GT96K Serial

What kind of router is this?
Are you using an internal CSU/DSU or external?
Typically, the CTS (clear-to-send) signal is generated by the DCE (CSU/DSU, modem, etc) as a response to the DTE's RTS (request-to-send). After the DCE detects carrier and waits a few milliseconds for it to stabilize, it will send the CTS signal to the DTE.
Your CTS should be "up."
Is this interface passing traffic?
Whats on the distant end and can you ping it?
