Specifies a delay in seconds between every dial-out failure.
The value zero indicates an infinite delay (no retry after
the first failure). Normally, FastHub will attempt a dial-out
if the mrNetMgmtModemDialString object is non-empty. If the
dial-out fails, and auto-answer has been disabled on this
system, the firmware will retry the dial-out after this delay
has passed. If auto-answer is enabled and the first dial-out
attempt fails, the system will immediately go into auto-answer
mode.
Default value: 300.
