Abstract: An interface panel comprising a respective socket for each local loop connection between a main distribution frame and a demarcation point, the socket comprising: a pair of first ports configured for connection to a respective wire pair extending from the interface panel to the main distribution frame; a pair of second ports configured for connection to a respective wire pair extending from the interface panel to the demarcation point; and a pair of third ports configured for connection to a respective wire pair extending from the interface panel to a Digital Subscriber Line Access Multiplexer (DSLAM).

Abstract: A splitter/combiner configured to split and combine Plain Old Telephone Service (POTS) signals and data service signals. The splitter/combiner comprises a line terminal configured to receive wires of a local loop connection to a Central Office of a communications network; a phone terminal configured to connect to telephone equipment at a customer premise; a data terminal configured to connect to a modem at a customer premise; a POTS line low pass filter connected between the line terminal and the phone terminal, the POTS line low pass filter configured to attenuate frequencies above 25 kHz and including a POTS line side transformer; a surge arrestor connected between the POTS line side transformer and the phone terminal; and a data line transformer configured as a differential mode choke connected between the line terminal and the data terminal.

Abstract: An apparatus for retrofitting an enclosure with a cabinet for digital service access equipment allows digital access equipment disposed in the cabinet to be accessible for coupling to other equipment disposed in the enclosure. The apparatus comprises a bracket, a wireway, and a fastener. The bracket is configured to attach to a substantially vertical surface of the enclosure. The attachment of the bracket to the enclosure provides a support for the cabinet. The wireway enables an interior of the enclosure to be coupled to an interior of the cabinet if the cabinet is attached to the bracket. The fastener attaches the cabinet to the bracket.
