- The best way is to use either a portable computer or one of the
- available Ethernet test boxes (e.g., Experdata) that can really
- test not just continuity, but whether the drop is really functional
- and connected to the net.
-
- Barring that, you can check for continuity between pins 3-10, pins
- 5-12, and pins 2-9. If there is a transceiver (or multiport xcvr)
- attached, there should be a transformer across each of these signals,
- which will shown continuity.
