Abstract: The present disclosure generally pertains to systems and methods for identifying subscriber lines coupled to transceivers of interest. In one exemplary embodiment, an end of a subscriber line is coupled to and terminated by a transceiver of interest. The other end of the subscriber line is coupled to a speaker. The transceiver is then selectively activated and deactivated causing it to transmit its normal frequency spectrum in a predefined pattern. The frequency spectrum includes frequencies audible to humans. Thus, the speaker produces sound capable of being heard by a human, and the sound exhibits periods of noise followed by periods of silence. Indeed, the periods of noise and silence are in a pattern according to the activation/deactivation pattern of the transceiver. Thus, a user can identify the subscriber line that is coupled to the transceiver by identifying which of the lines is coupled to the speaker when the speaker emits noise and silence according to the predefined pattern.

Abstract: The present invention relates to relates to electrical connectors, and in particular to a connector that replaces industry standard “punch down block” wiring devices to eliminate the need for rewiring when changing or re-routing multiple phone lines at a given location. The present invention provides for the connection of edge card connectors to punch down blocks or other wire terminating devices that are permanently connected to incoming and outgoing phone lines in a unique way by the use of jumpers that eliminate the need for rewiring when changing or re-routing multiple phone lines at a given location. A key advantage is that the invention makes the re-routing operation foolproof in that access to the permanently connected wiring is no longer necessary thereby eliminating the possibility of negatively affecting the integrity of the phone network by attempting to customize the wiring connections.

Abstract: An apparatus for isolating ADSL signals from POTS signals includes a single low pass filter for filtering the POTS signals for all POTS terminal devices within a customer's premises. The low pass filter is mounted within a line isolation device (LID) connected between a telephone jack and an ADSL transceiver. The customer's wiring is altered so that the ADSL and POTS signals are supplied to blue (B) and yellow (Y) lines, rather than the typical connection to the red (R) and green (G) lines, and the LID returns filtered POTS signals on the R and G lines. The telephone jacks within the premises remain connected to the R and G lines and receive the filtered POTS signals from the LID. Instead of reconnecting incoming signals to the R and G lines upon removal of the ADSL transceiver, a jack is preferably used which automatically shorts the B and Y lines to the R and G lines, respectively, upon removal of the LID from one of the telephone jacks.

Abstract: A line isolation device (LID) for use in an ADSL system provides a single low pass filter that filters out the higher band ADSL signals for all of the Plain Old Telephone Services (POTS) terminal devices within a customer's premises. The LID may be easily added to an existing ADSL system by routing signals from a customer bridge through the LID. The LID has a low pass filter for removing the ADSL signals and also has a bypass path for carrying unfiltered ADSL and POTS signals to an ADSL transceiver unit. The filtered POTS signals are supplied back to the customer bridge and to binding posts on the customer bridge where all POTS terminal devices receive their POTS signals. The re-routing of the signals within the NID through the LID can be easily accomplished by disconnecting a testing jack on the customer bridge and routing the signals through the LID. Alternatively, the customer bridge may be completely removed from the NID and replaced with a customer bridge having an integral low pass filter.

Abstract: A telecommunications wiring system reliably provides fast configuration and reconfiguration of user telecommunications devices within a localized telecommunications network. A series of piping assemblies creates a network of pair appearances in multiple. Then, hard-wired pair selectors, extractors, are used to connect at least one preselected signal from the piping assembly to the telecommunications device. Since only several of the many signal paths are permanently spliced within the connector of the extractor, only those several paths provide a continuous path for transmission. Whenever the position of a telecommunications device needs to be changed within the network, the extractor associated with the telecommunications device is unplugged from the piping assembly to accompany the telecommunications device to its new location.
