Dual Wiring of 2-Wire and 4-Wire Endpoints
Do not simultaneously wire a 2-wire and 4-wire endpoint to the same equipment location in an
MDF, even though they connect to different colored wire pairs. The system uses separate circuit
packs to interface 2- and 4-wire endpoints, and none are capable of interfacing both.
