Abstract:
The invention refers to a telecommunications system comprising a module rack that defines a core bay, a service plane and a rack interface plane where the service plane is transverse to the rack interface plane. The core bay is in part bounded by the service plane and the rack interface plane. The telecommunications system also comprises a series of electronics modules each defining an electronics orientation plane where each of the modules includes two opposed cooling surfaces oriented substantially parallel to the electronics orientation plane. Each of the electronics modules is removably secured within the core bay. The series of the electronics modules forms an array such that their electronics orientation planes are substantially perpendicular to both the rack interface plane and the service plane. The array also defines at least one coolant stream passage across each cooling surface. Further the telecommunications system includes a coolant movement means for moving a coolant through the coolant stream passages and across the rack interface plane. As such, the coolant convects heat away from the cooling surfaces of electronics modules more efficiently and effectively than found in the prior art as it, amongst other things, shortens the distance over which the inlet coolant is required to travel to cool the same functional density and provides a coolant to the passage at approximately a uniform temperature for each module.

Abstract:
A modular expandable telecommunication system having a main cabinet and at least one expansion cabinet that are interconnected with each other to obtain an extended telecommunication system with increased connection possibilities for extensions and trunks. The main cabinet and each expansion cabinet have a transmission interface unit allowing connection of the expansion cabinet(s) to the main cabinet via a single transmission link conveying voice/data channels and low level signaling for mutual synchronization and clock recovery for all interconnected cabinets. The main cabinet has a master clock device, a CPU for running software applications and a DSP for routing the higher level messages issued by the CPU depending on the physical location of the expansion cabinet.

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:
An electronic device in the form of a network communications module that includes a housing that defines an envelope and a vertical, substantially T-shaped routing channel within the envelope. The housing further defines a horizontal routing channel within the envelope that is in communication with the T-shaped routing channel. A plurality of boards is arranged vertically within the housing and at least one board includes input-output ports. At least one communication conduit is coupled to an input-output port. Boards that include input-output ports are recessed with respect to the envelope and are arranged such that the input-output ports are adjacent the T-shaped routing channel. Communication conduits are routed through at least a portion of at least one of the routing channels. Support walls are provide within the housing that help prevent cross-talk and redundancy is provided in some of the device's components and functions.
