These telephone cords are the RJ11 type. The RJ11 connector is the most common interface used for terminating telephone cord wires. RJ11 cables are 6P4C (six position, four conductor). Our telephone cords can connect a wide variety of communications equipment including phones, hubs, DSL/cable modems, and other telephone applications. The CNC301 series of patch cords are wired in reverse and used for connecting your communications/phone equipment to a jack. Telephone patch cords wired straight-through are for patching between communications equipment or between panels.
