Abstract: A telecommunications chassis includes one or more vents on a first side of the chassis and one or more vents in a second side of the chassis, one or more fans mounted inside the chassis and oriented to direct air flow inside the chassis from side to side, one or more open card slots inside the chassis between the one or more fans and the first side, and one or more hot-swappable power supplies inside the chassis between the one or more fans and the second side. One or more replaceable air filters over the one or more side vents, as optional are also included. The open card slots may be cPCI compliant. The chassis may also include an alarm card.

Abstract: A distributed computing system comprises a primary server having a primary virtual shared memory and a back-up server having a back-up virtual shared memory. The primary server periodically provides a state table to the back-up server in order to synchronize the virtual shared memory and the back-up virtual shared memory. A plurality of client computer resources are coupled to the primary server and the back-up server through a network architecture. The client computer resources further comprise plural worker processes each adapted to independently perform an operation on a data object disposed within the primary virtual shared memory without a predetermined assignment between the worker process and the data object. Upon an unavailability of either the primary server or the back-up server, the worker process performs the operation on the corresponding data object disposed within the back-up virtual shared memory.

Abstract: A distributed telecommunications system includes a master server, a back-up server and a plurality of computing nodes. The back-up server monitors the operational status of the master server, via a heartbeat process or a polling process. If the master server fails operationally, the back-up server assumes the role of the master server. The new master server requests a new back-up server via a tuple space command. One of the available computing nodes assumes the role of the new back-up server.

Abstract: An Electromagnetic Interference/Radio Frequency Interference (EMI/RFI) shielding plug insert for a modular connector jack is disclosed. The modular connector jack can be shielded with electrically conductive walls. It has metal contacts for transmitting or receiving data. One or more spring contacts protrude inside the modular connector jack from the walls and outside the modular connector jack. A shielded plug made of electrically conductive material is inserted into the connector jack such that the shielded plug comes into contact with the spring contact. Thus, the shielding plug and the connector jack are electrically connected and at the same electrical potential. Thus, the shielded plug provides interference shielding for unused connector jacks.
