In a local area network (LAN) for intelligent patching system controllers: Communications interfaces include: a connector port that has housing that defines a plug aperture and at least first through eighth contacts that extend into the plug aperture; an Ethernet interface (e.g., an Ethernet switch); and a multi-drop communication interface (e.g., an RS-485 transceiver); first through fourth conductive paths are provided that electrically connect the respective first through fourth contacts of the connector port to the Ethernet interface; and fifth and sixth conductive paths are provided that electrically connect the respective fifth and sixth contacts of the connector port to the multi-drop communication interface. Controllers include: an input connector port and an output connector port that each have first through eighth contacts, wherein the fifth and sixth input contacts are connected to the fifth and sixth output contacts; and a processor that is selectively connected to the first through fourth input contacts and to the first through fourth output contacts, and to the fifth and sixth input contacts and to the fifth and sixth output contacts via a multi-drop communication transceiver.
