Abstract:
An arrangement of plural filter circuits on a single card, and interconnection and mouthing of numerous cards on a single rack to facilitate maintenance, is provided for use in a telco. In each of the filter circuits, there is a first plurality of inductors connected in series in a first leg of a balanced line configuration of filter, a second plurality of inductors connected in series in a second leg of the balanced line configuration of filter, and a plurality of capacitors connected as cross branches between terminals of the inductors. A substrate supports the capacitors and the inductors, wherein each of the inductors is a toroidally wound inductor comprising a toroidal core of magnetic saturation inhibiting material. The saturation inhibiting core material allows reduction in size of a cross-sectional dimension of the core to approximately the cross-sectional dimension of one of the capacitors. For telco equipment, a set of connectors is mounted in a back plane of an enclosure for receiving the cards, and a plurality of bypass switches are disposed in the set of connectors for bypassing voice signals around corresponding ones of the cards. The bypass switches are placed in a state of conduction upon removal of a corresponding one of the cards from the set of connectors.
Abstract:
A cross-connect panel for a computer network is disclosed that provides a mechanism for connecting to the signal transmission media of the network. In the typical scenario, the inventive cross-connect panel replaces the common cross-connect panel that receives the various cables running between the remote nodes and the hub, switch, or other network communications device. The panel has a series of panel-node connectors that are adapted to receive the signal transmission media from the network nodes. The cross-connect panel also has panel-device connectors that in most embodiments will be of a standard type to connect to the network communications device. The panel-node connectors and the panel-device connectors are electrically interconnected to each other via a backplane to complete the communications links. The panel further includes a monitoring port that is also preferably connected to the backplane to provide physical layer access to the communications links. In this way, a network monitoring device interfacing with the port may be connected directly to the network's communications links or disconnected when monitoring is not necessary.
Abstract:
An apparatus and method for mounting an xDSL signal splitter that is readily interconnected with existing indoor premises telephone wiring to provide separate access to voice and data signals by the subscriber. The apparatus comprises three pairs of terminations for connection of combined signal wiring, first signal wiring and second signal wiring. A first splitter circuit is mounted in the housing and electrically connected between the first pair of terminations and the second pair of terminations. A first signal jack extends through the exposed surface of the housing and is connected to receive only the first signal. In an alternative embodiment, the third pair of terminations is electrically connected to a branch point between the first pair of terminations and the first splitter circuit. In another alternative embodiment, a second splitter circuit is mounted in the housing and electrically connected between the branch point and the third pair of terminations. A second signal jack extends through the exposed surface of the housing and is connected to receive only the second signal.
Abstract:
An electronically controlled main distributing frame (ECMDF) establishes main distributing frame (MDF) type connection in response to control signals without requiring a craftsperson to connect a jumper wire. In accordance with one application of such ECMDF, a local switch can receive signals from a customer requesting connection to a specials service provider such as the Internet. In response to the receipt of such signals, the connection in the ECMDF is altered to provide a more direct connection to the service provider bypassing the local switch. Advantageously, such an arrangement allows the long holding times of Internet connections to be established through a bypass network while allowing the customers who have requested such a connection to be provided with normal telephone service when they are not on the Internet.
Abstract:
The location of a termination in a properly terminated LAN can be remotely detected. The cable's skin effect produces a detectable signature at the sending-end when a step function, for example, reaches the termination. Accordingly, a network analysis device is connected to the network to inject the step function onto the network cabling. The voltage response of the cabling to this is first digitally sampled and then analyzed in a system controller. The system controller reviews the sampled data for an inflection point and then locates the termination by reference to the delay between when the signal was placed on the cable and the detection of the inflection point.

A network termination equipment for connecting telecommunications apparatus to a telecommunications network has operative elements to perform terminal functions. The termination may perform line diagnostic functions, remote telemetry functions. Alternative front plates are connectable to intermediate plate to configure the termination equipment to perform the different functions necessary for additional services or to control access to the network to authorized users only.
Abstract:
The outside distribution plant of the invention consists of a remote terminal such as a digital loop carrier, broadband distribution element or the like that receives telecommunications signals from a switching system or other network element. The signals are delivered to a variety of different types of line cards where each of the different types of line cards provide a different type of telecommunications service as is known in the prior art. Connection lines emanating from the line cards are connected to the inputs of a remotely controlled crossbar array where the inputs of the array can be selectively connected to the outputs of the crossbar array. The outputs of the crossbar array are connected to distribution lines that terminate at one of a plurality of feeder distribution interfaces that connect to customer lines that terminate at customer premise equipment. The crossbar array serves as the access point for competitive service providers. Specifically, distribution lines from competitive service providers are connected to the inputs of the crossbar array. Those distribution lines can then be connected to any feeder distribution interface to provide competitive service to any customer hosted by the feeder distribution interfaces under the control of an OAM&P system. Thus, the elements of the outside distribution plant that provide the connection to every customer premise do not have to be duplicated and access is provided to any potential customer hosted by those elements.
Abstract:
An architecture, as well as various components, of an asynchronous transfer mode (ATM) subscriber access multiplexer (ASAM) system can be implemented using an xDSL (x-Digital Subscriber Line) using DMT (Discrete Multitone) or CAP (Carrierless Amplitude Phase Modulation) between a plurality of subscribers and a corresponding plurality of line termination equipment in a shelf that also includes network termination equipment for connection to an ATM network. The line termination and network termination equipment are interconnected by a bus internal to the shelf for providing subscriber access. Separate lowpass filters are provided at each end of a twisted wire pair between the shelf and each subscriber equipment. A shelf can be used as a hub for connecting to a remote shelf that includes the line termination equipment for connection to subscribers. Although the internal bus of the shelf 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 and the other half in the other shelf and sharing network termination equipment between such shelves.
