In the below context:
Finally had the time over the weekend to patch everything down and sort out the sockets.
I managed to get my trusty router patched in with the phone line coming from the hallway to the cab via the CAT6 cable.
What does the term patched mean, and what is its origin? It's clearly AmEng, but as a Brit I can't be sure whether it simply means patching in the normal IT sense of connecting two systems together, or whether it has a more nuanced definition that has temporary connotations.
