Abstract
An apparatus for verifying port and slot assignments of cable bundles that extend from a telephony filtering device, including Digital Subscriber Line (DSL) infrastructure. The apparatus may have a circuit board that inserts into a vacant slot of a frame of DSL equipment. The circuit board (sometimes called a LC circuit board) provides a connector that provides electrical continuity from a voltage driven indicator to, e.g. a slot-to-slot interface. One lead to the indicator may be held to a high voltage by a voltage source. A remaining lead, or probe input, may be connected to a common ground to cause the indicator to illuminate. Frequently, the common ground circuit closure may occur at a Main Distribution Frame (MDF). Such a circuit board may be installed in a data only shelf, i.e. wherein Line Cards (LC) that ordinarily populate the shelf support data traffic that arrives via the slot-to-slot interface. A companion board, or LPF circuit board, may be placed in a slot where a Low Pass Filter (LPF) would ordinarily be located. The LPF circuit board mates to a slot-to-slot interface, providing a conductive link through from the indicator through the slot-to-slot interface and out to a slot-to-MDF interface, wherein an MDF is a main distribution frame suitable for connecting twisted wire pairs to telephony and other equipment. LPF circuit board may provide at least one switch to alternately connect a subscriber line portion of the MDF to the indicator or a PSTN portion of the MDF to the indicator.
