Each modular adapter comprises an insulated housing comprising a modular jack portion and either a coaxial connector portion or a twin-lead cable portion. A standard, six-position modular telephone jack is positioned in the modular jack portion. A male coaxial connector is positioned in the coaxial connector portion, while a 300 ohm twin-lead cable is positioned in the twin-lead cable portion. The conductors of the modular jack are electrically connected to the solid central conductor and the conductive wire sheath of the coaxial connector, or to the wires of the twin-lead cable. The modular connector cable comprises an insulated cable having first and second ends terminated respectively by first and second standard, six-position modular telephone connectors insertable into the modular jacks of the first and second adapters.
