Abstract:
A modular digital telephone system and method featuring a universal telephony shelf adaptable for incremental expansion of legacy telephone switches and as a building block in the construction of new telephony switches. The shelf includes identification and connectors for shelf pairing, and is adapted to receive redundant power supplies, plural line cards, and either a peripheral shelf interface unit or a switch array card upon which is located a flash memory device utilized for reconfiguration purposes of a resident field programmable gate array.
Abstract:
A method of arbitrating access to a system bus in a telephone switching system for a plurality of requesters by assigning a priority level to each requester, and granting access to the bus based on the number of requesters, the priority of the requestors and the timing of the requests.
Abstract:
An apparatus and system is provided for coupling an ethernet switch to communication link(s) in a communication network without requiring the disconnection and reconnection of the communication link(s). A module is configured to accommodate components of an ethernet switch, and can be modularly introduced into a communication rack and quickly engaged with rack-mounted mating connectors which are coupled to the communication link(s).
Abstract:
A patch panel is disclosed which is easily expandable as required by a customer and which substantially simplifies conventional field servicing practices. The invention provides a patch panel comprising an assembly of at least one connector and printed circuit board with the connector being mounted upon the printed circuit board; a mount for removably supporting the assembly of at least one connector and printed circuit board in a desired location relative to the mount and a panel for detachably holding the mount in a predetermined position to the panel such that the panel prevents removal of the assembly of at least one connector and printed circuit board from the mount.
Abstract:
Disclosed is a novel connector module structure, to be installed in a system to form connection between at least two functional modules. The connector module provides jumper connection capabilities, i.e., allowing one of its connection terminals to form electrical connection with a connection terminal of one or more particular non-adjacent connector modules.
Abstract:
A modular system for the connection of an external communication network to a user network of a building includes: a user module including: a passage opening of a connection cable of the user network including optical fibres associated with respective users and adapters associated with respective optical fibres of the connection cable of the user network, and an operator module including: an inlet opening of at least one connection cable to the external communication network including optical fibres and an outlet opening of fibre optic connection elements connected to the external communication network and provided with a connector at a terminal end thereof. The user module and the operator module are structurally independent from each other and the external communication network is operatively associated with the user network by means of a connection of the connectors of the fibre optic connection elements with respective selected adapters of the user module.

Abstract:
An assembly (10) of three telecommunications modules (12, 14, 16) each having an equal number of contacts for connecting wires (18, 20, 28) therewith, comprises splitter circuits (30′, 30″), the number of splitter circuits (30′, 30″) being equal to half of the number of contacts of each module (12, 14, 16), one third of the contacts (24, 74) of the assembly (10) being adapted to transmit a line signal, one third of the contacts (22, 72) of the assembly (10) being adapted to transmit a POTS signal, and one third of the contacts (26) of the assembly (10) being adapted to transmit a DSLAM-signal. A module, particularly for use within an assembly, is open at a side other than a front side, at which contacts are exposed, so as to allow at least one splitter circuit (30′, 30″) to be at least partially inserted into the module.
Abstract:
A telecommunications patching system includes: a rear panel, the rear panel including a plurality of cutout areas; a series of central compartments mounted to the rear panel, the central compartments being disposed in adjacent, vertically stacked relationship in at least one column, the rear ends of the central compartments being aligned with at least one of the cutout areas; and at least one series of lateral compartments mounted to the rear panel, the lateral compartments being disposed in spaced apart, vertically stacked relationship and laterally positioned from the central compartments, the rear ends of the lateral compartments being aligned with at least one of the cutout areas. The system also includes at least one central patching module with a plurality of connectors, the central patching module residing in one of the central compartments, the plurality of connectors being oriented to receive a communications cable from a lateral direction, a rear end of the central patching module extending rearwardly through a respective one of the cutout areas; and at least one lateral patching module with a plurality of connectors, the lateral patching module residing in one of the lateral compartments, the plurality of connectors being oriented to receive a communication cable from a lateral direction, a rear end of the lateral patching module extending rearwardly through a respective one of the cutout areas.
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.
