Abstract: A coax-balun module for converting from a balanced signal to an unbalanced signal includes a housing having a balun well adapted to receive a balun transformer. The module includes a printed circuit board electrically connected to a balun transformer and a threaded connector. The printed circuit board is further electrically connected to electrical conductors adapted to carry input signals. The housing is adapted to receive a potting material to seal the other components therein.

Abstract: Methodologies and structure are provided for use in a communications line that transmit data without plain old telephone service (POTS), or splits the POTS service from the data service, to inhibit oxidation of electrical connections within the physical communications line between the central office of a service provider and a subscriber premises and/or subscriber equipment. A direct current load is drawn by a sealing current terminator circuit that is electrically coupled across the communications line at a convenient location proximate or within the subscriber's location so as to assist in providing oxidation reducing direct current flow along a portion of the communications loop coupling the service provider with the subscriber.

Abstract: Described is an apparatus for permitting installation of voice over internet protocol (VoIP) service at a subscriber premises. A VoIP adapter is provided that is configured to enable application of sealing current to an outside line while permitting use of analog equipment on a VoIP enable premises wiring system. The VoIP adapter includes a high-pass filter portion that permits the use of existing premises analog equipment.

Abstract: An apparatus and method is provided for permitting a service provider technician or subscriber to install a twisted wire pair to coax adapter within a network interface device (NID) at a subscriber premises. The twisted wire pair to coax adapter is configured for snap-in mounting within a NID. The adapter includes input and output connections, as well as an internally disposed balun, and is configured to convert communications signals carried on a twisted wire pair to communications signals carried on a coax cable to avoid degradation of the signals resulting from the use of an unshielded twisted wire pair within a subscriber premises.
