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 communication system is adapted to accommodate changes to bandwidth demand through the use of communiucation interface modules, such as radio modules (121-124), are coupled to a communication signal processor, such as a multi-port modem (110), in order to serve an initial bandwidth demand. Thereafter, additional communication signal processors may be added, being coupled to one or more of the communication interface modules (121-124) decoupled from the initially deployed communication signal processor (110), to serve an increased bandwidth demand. Preferably, an expansion chassis architecture is used to accomodatea number of communication signal processors atleast equivalent to the number of communication information interfaces of the plurality. In preferred embodiments, the communication interface modules operate upon different channels, such as radio frequency channels, although coupling to the communication signal processor upon a same channel, sucha as a common intermediate frequency channel.
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:

Abstract:
A head-on or modular structure for storing audio/video/telecommunications hardware and associated components includes a first support framework including an upper portion, a lower portion and a first plurality of cable guides mounted in a substantially vertical orientation thereon, and a second support framework including an upper portion, a lower portion and a second plurality of cable guides mounted in a substantially vertical orientation thereon. A first and second cross-member each adjoin the first and second support frameworks in a substantially perpendicular relation thereto near the respective upper portions thereof, and a walkway adjoins the first and second cross-members. An HVAC system is integrated into the modular structure. The modular structure can be used as a stand alone unit or adjacent modular structures can be joined together in the horizontal and/or vertical orientation.

Abstract:
An electric power and signal distribution system provides for connecting distribution modules (5) to one another in succession by means of connecting plates (28) and screws (29), and for connecting each distribution module (5) by means of screws (25) to a respective cabinet (3); each distribution module (5) having a duct (6), and at least one portion (15) of electric line which is housed inside the duct (6) and has a number of electric power distribution connectors (16).
Abstract:
A modular, re-enterable telecommunications terminal (50), for making and breaking connections with insulated wire conductors, includes one or more base frames (52) supporting wire termination modules (55, 56) thereon, and a multi-pin socket (60) thereon is connected to another base frame (52) by one or more bridging modules (100). The termination modules (55, 56) are manually operable for terminating wires in insulation displacing connectors (70, 85), and are selected and positioned according to the type of terminations desired. Manually pushing and pulling the termination module drivers (65, 80) toward and away from the base frames (52) effects movement of the wires between connected and open positions.
