There is provided media converter having an integrated local information transmission function and a fault alarm signal communication system for transmitting local information using a frequency outside the communication frequency bands for data signals. In the subscriber's media converter, based on input local information, a control section sets a transmission frequency outside the communication frequency bands and outputs a signal instructing that a transmission be made. A media independent interface section receives this signal and transmits the signal in the instructed frequency. In the station media converter, a media independent interface section detects the frequency in which the local information is transmitted from the received signal. A control section then generates local information using the detected frequency and outputs it to an SNMP unit.

A coaxial cable connection assembly includes a cable tap connector for engaging with the coaxial cable, a transceiver for transmitting and receiving information signals to and from the coaxial cable via the cable tap connector, a drop cable connector for electrically connecting the transceiver to a station device, and two matable coupling members for engaging and electrically connecting the transceiver with the cable tap connector. The tap connector has an axis along which the coaxial cable is disposed when the connector is engaged with the coaxial cable. The tap connector also has an outer face substantially parallel to the axis thereof, and includes outer and center conductor contact members for respective electrical connections with the outer and center conductors of the coaxial cable. The transceiver includes a casing having first and second intersecting faces. The drop cable connector is mounted on the first face of the transceiver. The coupling members have circular or equilateral polygonal cross sections, and are mounted respectively on the outer face of the cable tap connector and on the second face of the transceiver. When the coupling members are mated together, the second face of the transceiver confronts the outer face of the cable tap connector, and the angle of the first face of the transceiver with respect to the axis of the cable tap connector is adjustable.
