I have an issue with a phone jack that I am looking for some basic direction in troubleshooting. I am being asked to support a phone system, even though I have no experience with telephony. The phone jack just stopped working and nothing is labeled so I am not sure how to trace to where the line is terminated. There are two sets of punch down blocks located on opposite sides of the office.
Any idea on what would cause a phone jack to stop working all of sudden ? No other lines are showing a problem. There is another phone jack located close (about 10 feet) from the jack that is having the issue. Is a way to switch the lines where they are terminated? If so would this be done with the punch block or in a patch panel? As I mentioned nothing is labeled and there are 2 telco closets so it is going to be difficult to pinpoint.
Thanks for any feedback/direction anyone can give.
