This object specifies a delay in seconds between every dial-out failure. The value zero indicates an infinite delay. Normally, the switch will attempt a dial-out if the netMgmtModemDialString object is non-empty. If the remote site then fails to answer, and auto-answer has been disabled on this system, the system will retry the dial-out attempt after this delay has passed. If auto-answer is enabled and the first dial-out attempt fails, the system will stop further dial-out attempts and immediately go into auto-answer mode. The default value is 300 seconds, or 5 minutes.
