Hi swamy,

I have taken below output from cisco tool: output interpreter, may be useful to you

"

Interface Serial1/0:1 (reset/down)
  WARNING: This interface has the status as reset.
  This is a hardware-related issue, such as, a defective smart jack, demarcation
  cable or controller, or a physical connection failure. This problem can occur
  if packets queued for transmissions are not sent for several seconds. Also, this
  issue may be caused when a modem does not supply the transmit clock signal, or
  when there is a cable problem. Whenever the Carrier Detect signal of the serial
  interface is up, and the line protocol is down, the IOS device periodically resets
  the interface in an effort to restart it. Interfaces can also be reset when they
  are looped or shut down.
