Narrative:
I have just recently noticed the abbreviation U/south being used a lot in the notams. I looked it up and it means 'unserviceable.' it seems to now be used instead of OTS (out of service); but I'm not sure it's the same thing. What is 'unserviceable' exactly and is it the same as OTS? For example; if a NOTAM shows the approach lights are U/south for a period of time; are they out of service?

Title: Pilot reported confusion between the difference in Out of Service and Unserviceable in NOTAMs.
Narrative: I have just recently noticed the abbreviation U/S being used a lot in the NOTAMs. I looked it up and it means 'unserviceable.' It seems to now be used instead of OTS (Out Of Service); but I'm not sure it's the same thing. What is 'unserviceable' exactly and is it the same as OTS? For example; if a NOTAM shows the approach lights are U/S for a period of time; are they out of service?
