Abstract:
An interface card (42) adapted to be mounted at the back plane (46) of a splitter chassis (44). The interface card includes card edge connectors (60, 62) for providing connections with a splitter card. The interface card (44) also includes cable connectors (54, 56, 58) for inputting mixed voice and data, and for outputting data and voice signals. Tracings (76, 84, 88, 80) are provided on the interface card for interconnecting the cable connectors and the card edge connectors. The tracings are configured such that first tracings carrying data signals from the splitter card to the cable connectors do not cross second tracings carrying voice signals form the splitter card to the cable connectors.
Abstract:
The present inventor 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 remote test interface (36) for testing a communication path (40) for digital subscriber line (DSL) signals includes a relay matrix that is coupled in the communication path (40) between a DSL access multiplexer (DSLAM)(28) and a DSL modem (39) located at a customer premises (30). The remote test interface (36) also includes a processor that is coupled to the relay matrix and that communicates with a loop management device (26) that is coupled in the communication path (40)between the remote test interface (36) and the DSLAM (28). This communication is performed using voice-band signals transmitted over the communication path (40). The remote test interface (36) further includes a signaling detector that is coupled to the communication path (40) and operable to detect a start test signal from the loop management device (26) that instructs the remote test interface (36) to prepare for testing of the communication path (40) by the loop management device (26) in collaboration with the remote test interface (36).
Abstract:
A universal demarcation point (10) for managing the delivery of communications services to a subscriber. The universal demarcation point provides an interface between a utility distribution network and subscriber owned equipment for use with fiber optic cables and copper cables. The universal demarcation point includes a utility accessible portion (12) and a subscriber accessible portion (14). The utility accessible portion (12) has a plurality of service modules (22). The service modules (22) are capable of plugging in to the universal demarcation point and convert the light signals that are transmitted on the fiber optic cables onto cables that are suitable for use in the subscriber's dwelling. The subscriber accessible portion (14) is adjacent to the utility accessible portion and has ports that enable the subscriber to test the integrity of the communications services delivered from the utility distribution network.

Abstract:
Apparatus is disclosed for testing a telephone line between a customer's network termination equipment and an exchange associated therewith. The apparatus comprises a field unit (5) positionable between the customer's telephone (1) and the network termination equipment (4), and an exchange unit (16) positionable at the exchange (2). The exchange unit (6) comprises activating means (16) for initiating a test sequence, and processing means (14) for controlling testing and analysing test results. The field unit (5) comprises a noise generator (12) for sending noise signals to the exchange unit (6), and a sensor (10) for activating the noise generator upon receipt of the activating signal. The processing means (14) analyses the incoming noise signal to provide a measure of the line attenuation.
Abstract:
The invention relates to a device for control/command of a plurality of man-machine dialogue facilities which are linked in series in such a way as to form a network. This device comprises a wire interconnection block linked by a point-to-point link to each dialogue facility via a network of twisted cables.
Abstract:
System for simultaneous exchange of analog voice band signals and digital data signals between user termination equipment and local exchange equipment via connection wires, comprising means for exchanging the data signals between the user termination equipment and the local exchange equipment in the format of a modulated carrier signal having a frequency spectrum above the voice band. The system comprises converting means (DSLAM, SBDSLM) for converting the digital data signals into data signals having a specific bandwidth and/or format, being fit to cause no substantial mutual interference between the voice band signals and the converted data signals, and means (MDF, Scab) to merge the converted data signals and the voice band signals to said common connection wires. The signals are merged on the user termination equipment side from the Main Distribution Frame (MDF) at which the cables with connection wires from the subscribers are terminated. Preferably converters are incorporated in MDF blocks. Also preferably broadband signals from DSLAMs that are normally used for servicing one (A)DSL subscriber are converted in smaller band signals and used as the data signals with specific bandwidth.
Abstract:
An assembled telecommunication exchange cabinet, comprising a hollow body and a base, wherein the body comprises a set of front doors, left and right side doors, a top cover and a heat sink device. A plurality of inlets are disposed on the bottom surface of the body, and a telecommunication exchange device and terminal boards are accommodated inside the body. The body accommodates a Digital Subscriber Line Access Multiplexer and a telecommunication exchange device, which in turn, are connected to the corresponding terminal boards. The left and right side doors and the top cover can be subsequently opened separately after the set of front doors is opened. In addition, the heat sink device of the body is disposed under the top cover. The base of the cabinet is removeably attached to the body; and at least one battery holder is further disposed inside the base to accommodate at least one spare battery.
Abstract:
A powered communications patch panel is adapted to power network devices connected to the communications patch panel.
