Abstract:
Systems and methods of cathodic protection. The system includes a metallic housing, a backplane situated within the metallic housing, a cathodic protection card coupled to the backplane and a permanent anode, external to the metallic housing, coupled to the cathodic protection card through an isolated port. The cathodic protection system is powered using span power. The permanent anode and metallic housing are adapted to form a closed circuit when both come in contact with an electrolyte. The permanent anode is maintained at a higher potential than the metallic housing.
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 high density device comprising: a chassis frame configured and dimensioned for mounting in a standardized telecommunications rack, the chassis frame defining a front plane and a back plane, the front plane being substantially coincident with a front support of the telecommunications rack; a sub-module chassis secured to the chassis frame, the sub-module chassis exhibiting a proximal face and a distal face; a first plurality of jacks located distal of the proximal face of the sub-module chassis; and a passageway formed between the sub-module chassis and an inner wall of the chassis frame, the passageway configured and dimensioned for the passage of cabling for connection to the first plurality of jacks.
Abstract:
A private branch exchange excellent in the workability of wiring work and protection of cable. The private branch exchange comprises a private branch exchange function section, and a casing for covering the private branch exchange function section while holding and comprising an intermediate bottom plate, a supporting post section and a base. On the front side in the casing, a cable for external connection can be connected with the private branch exchange function section. The intermediate bottom plate supports a part of the casing for storing the private branch exchange function section from below. The supporting post section is connected to the lower surface side of the intermediate bottom face. The base is connected to the lower part of the supporting post section and supports the casing entirely. Furthermore, front side of the supporting post section is curved to protect the connection cable passing between the intermediate bottom face and the base.
Abstract:
A telecommunications apparatus for use with a signal lamp. The apparatus includes a jack having a jack body defining an IN port, an OUT port and a MONITOR port. The ports are aligned along a vertical line with the OUT port positioned above the IN port and the MONITOR port positioned above the OUT port. A first set of spring contacts is provided for contacting a plug inserted in the IN port, a second set of spring contacts is provided for contacting a plug inserted in the OUT port, and a third set of spring contacts is provided for contacting a plug inserted in the MONITOR port. The telecommunications apparatus further includes a lamp switch for activating teh signal lamp when a plug is inserted in the MONITOR port. The lamp switch is positioned below the third set of spring contacts and above the second set of spring contacts.
Abstract:
The invention relates to a jack assembly including a jack mount with a jack receiving region. A jack is adapted to be slidably mounted in the jack receiving region. The jack includes a jack body formed of a dielectric material and a plurality of electrically conductive tip and ring springs. The jack body defines a plurality of bores sized to receive plugs having tip and ring contacts. The jack assembly further includes a plurality of cross-connect contacts and a rear interface assembly including a dielectric support. A plurality of rear connectors project outward from the dielectric support, and a circuit board is positioned between the jack mount and the dielectric support. The circuit board provides connections between the cross-connect contacts and the normal contacts. An electrical interface between the jack and the circuit board is configured such that when the jack is removed from the jack mount, the jack is automatically disconnected from the circuit board.
