A read-write integer, 0 to 172800 seconds, up to 48 hours, setting how long a manual operation stays in effect before the system automatically clears it, with 0 meaning no timeout. This acts as a safety mechanism preventing a technician's manual override or test operation from being accidentally left active indefinitely, automatically reverting the equipment to normal operation after the configured time. An admin performing a temporary manual loopback test might rely on this timeout, set to a couple of hours, to ensure the operation automatically clears itself even if they forget to manually end it.
