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:
Retarding a fire condition of a telecommunications component mounted on a module to be inserted into a telecommunications box is provided. The module may have a planar surface having a first side and a second side generally opposed to the first side. A ventilator provides a cross air flow generally in a direction from the first side to the second side. A first opening in the telecommunications box in an area adjacent of the first side of the planar surface forms a substantial portion of the cross air flow emanating from the first side. A second opening in the telecommunications box arranged in an area adjacent to the second side of the planar surface exhausts the cross flow air, such that the cross flow air substantially retards the fire condition. An air flow guide is provided to simulate an air resistance of a module.
Abstract:
The invention relates to a distributor device (1) for use in communication and data systems technology, comprising at least one distributor connection module (7). Said distributor connection module (7) comprises a housing (16, 17) which houses input and output contacts, accessible from the exterior, for connecting lines, cables or wires. The distributor device (1) comprises at least one additional connection module (2) which comprises at least one SDH/SONET transport interface (6) and outputs for electrical signals. The outputs of the connection module (2) are connected to inputs of the distributor connection module (7). The connection module (2) comprises at least one converter for converting SDH/SONET transport signals to E1 signals and vice versa. The invention also relates to a corresponding connection module (2) and a corresponding distributor connection module (7).
Abstract:
A distribution cabinet (1) for accommodating weak-current distribution installations, in particular for arranging outdoors, havinga base box (2),an outer cabinet body (3) with at least one door (4),a cabinet cover (5), andan inner installation frame (6),the installation frame (6) being made up of profile sections (50), of which the cross-sectional shapes has two insertion pockets (51a,b), of which the insertion directions (52a,b) run at right angles to one another.
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 which provides both a local shelf interface and three interface units for connection to the peripheral interface units of other shelves. System wide fault displays are provided.
