Abstract:
Electronically establishing communication line cross-connections involves providing a controllable matrix of relays and a plurality of filters. A composite signal comprising low and high frequency components is received at the relay matrix, which is controlled to direct the composite signal to a particular filter. A filtered low frequency component is provided at a particular filer output. The relay matrix is controlled to direct at least the high frequency component to a relay matrix output. The low frequency component of the composite signal may comprise a voice band signal and the high frequency component of the composite signal may comprise a data signal. The relay matrix may be controlled locally or remotely. The relay matrix may be controlled to significantly reduce the number of inactive connections established between digital access multiplexers and a main distribution frame or voice switch.
Abstract:
A network interface device (11) includes an enclosure that houses active electronics for accomodating twisted-pair telephone wires and coaxial cable. The housing has a base (13) that connects to a building wall. A shield (29) locates within the housing, the shield having a platform and a perimeter wall (31) that extends around the platform. A printed circuit board (43) mounts within the shield (29) between the base and the platform. The shield (29) 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 (73) mounts on the platform. The subscriber bridge module (73) has subscriber line termination points (81, 82) on one side that electrically connect with the subscriber lines (83). The subscriber bridge module (73) also has telephone jacks (85) electrically connected between the subscriber termination points (81, 82) and the provider line (87). This provides a demarcation between the subscriber lines (83) and the provider line (87). An inner cover (99) encloses a provider line port (59), any voltage protecting devices (55) mounted on the platform, and power terminals on the subscriber bridge module (73).
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:
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.
