Try disconnecting and reconnecting all connections. I work in telecom and for years I had been told that a cable cannot go bad just lying in a cable tray. Well, I discovered that isn’t true. It can go bad all on its own just lying in a cable tray screwed down at both ends. No one knows what happened and there was no physical damage to the cable.
Also, jacks will get dirty. There is a fix for a DSX cross-connect (it’s for T1 testing and patching) where you insert and remove a bantam cable several times. It’s surprising how often this “fix” works. 73, Joel - W4JBB > On Jun 25, 2015, at 4:45 PM, James Bennett <[email protected]> wrote: > > Tried it.
