Abstract:
A patch panel includes a back plane having front mounted pairs of termination locations, and an interconnect location electrically connected to each pair of termination locations. The termination locations connect to two patch cords. The interconnect location defines an access device for selectively accessing the termination locations. An interconnect module interfaces with the interconnect location. The module can include test access, power over Ethernet, or circuit protection features.

Abstract:
A network interface device for Ethernet networks using unshielded twisted pair cables comprising an overvoltage protection module and an interconnection module connected to the overvoltage protection module, both modules being connected in series in the Ethernet network.
Abstract:
Asynchronous Transfer Mode (ATM) cells are conveyed over a shelf bus to and from an NT (network termination) card inserted into the bus connected to an ATM network and to a plurality of LT (line termination) cards also inserted into the bus, wherein the NT card processes the ATM cells and provides downstream cells to the bus with a guard byte and upstream cells to the ATM network without a guard byte.
Abstract:
A shelf or housing is connected to a narrowband network and to a broadband network for serving a plurality of subscribers includes two sections, one for lowpass filters and another for line and network termination cards. The line termination and network termination equipment are interconnected by a bus internal to the shelf for providing subscriber access. The shelf or housing can be used as a hub for connecting to a remote shelf or housing that includes the line termination equipment for connection to subscribers. Although the internal bus of the shelf or housing is shown in a non-redundant embodiment, an increased level of equipment protection can be provided by placing one half of a redundant equipment pair in one shelf or housing and the other half in the other shelf or housing and sharing network termination equipment between such shelves or housings.
Abstract:
A powered communications patch panel is adapted to power network devices connected to the communications patch panel. Power is supplied to the network devices by the powered communications patch panel over the communication cabling. The powered communications patch panel may be provided with a management port to allow remote management of the patch panel via a network connection. Multiple management ports may be provided, allowing patch panels to be connected to one another in a daisy-chain configuration.
Abstract:
The present invention is directed to a telecommunications system and access panel for providing direct metallic access to a telecommunications carrier's signal pairs by a competitor while providing isolation between the telecommunications POTS service and the competitor's digital line service. The isolation is provided by placing DC blocking capacitors in the access panel. In another embodiment, direct metallic access is achieved by placing the access panel as an intermediate distribution frame member.
Abstract:
A terminal block (64) of a telecommunications distribution point comprises at least one group of subscriber contacts, at least one group of XDSL contacts, at least two groups of backbone contacts, each backbone contact of the first group being connected to a backbone contact of the second group, and at least one splitter assembly (32) connected to the subscriber contacts, the XDSL contacts and the backbone contacts of the first and/or second group. A distribution point comprises at least one such terminal block.
Abstract:
A housing for hot-pluggable network tap modules. The housing allows a user to maintain all network taps in any given system in one housing and location. This increases the ease of maintaining multiple network taps and allows the network tap modules to be powered by a power supply included with the housing. The housings can greatly simplify the process of managing multiple taps. Moreover, the housing are compatible with hot-pluggable network tap modules as well as legacy network tap modules that were developed in the past.
Abstract:
A network interface device includes an enclosure that houses active electronics for accommodating twisted-pair telephone wires and coaxial cable. The housing has a base that connects to a building wall. A shield locates within the housing, the shield having a platform and a perimeter wall that extends around the platform. A printed circuit board mounts within the shield between the base and the platform. The shield is hinged to the base so that it may be readily removed with the printed circuit board if repair is needed. A subscriber bridge module mounts on the platform. The subscriber bridge module has subscriber line termination points on one side that electrically connect with the subscriber lines. The subscriber bridge module also has telephone jacks electrically connected between the subscriber termination points and the provider line. This provides a demarcation between the subscriber lines and the provider line. An inner cover encloses a provider line port, any voltage protecting devices mounted on the platform, and power terminals on the subscriber bridge module.
