Ethernet cable questions
sal_park:
So this is the back of the patch panel in question:

And my geto 1/2 an ethernet cable:

And how each ethernet pair is terminated to test with the multimeter:

RobertHolcombe:
Seems pretty confusing
Process of elimination - you re-terminated the patch panel; disconnect what you punched down and measure the cable/wall socket without the patch panel connected. If it checks out terminate a pair on the patch panel, test again.

What are those sockets? A lot of sockets have built in transformers and termination resistors.

Only the sockets for devices do this. The sockets for wall sockets and patch panels are pure connectors, since they aren’t endpoints.

One common exception is sockets intended for phone use. Even if they're 8p8c / RJ45 (insert argument about naming here). The patch panel shouldn't have any of that, but the wall socket might.

Do you have some examples of that?
I've worked on and installed 100 or so ethernet and telephone jacks and I've never come across any that actually have components.
it's all just terminals to the Jack or punch down to the jack.
