Methods, systems, and computer program products for clustering and communicating between Internet protocol multimedia subsystem (IMS) entities and for supporting database access in an IMS network environment. According to one aspect, an IMS cluster node includes a serving call state control function (S-CSCF) for controlling media sessions between IMS users. The cluster node further includes a home subscriber service (HSS) function for storing and providing IMS subscription information to the S-CSCF function. A shared memory is operatively associated with the S-CSCF function and the HSS function. The S-CSCF function obtains IMS subscription information from the HSS function via the shared memory.

Methods, systems, and computer program products for supporting database access in an Internet protocol (IP) multimedia subsystem (IMS) network environment are disclosed. At least one call state control function (CSCF) entity generates subscriber-related queries according to an abstracted profile (AP) protocol. At an abstracted profile server (APS), a CSCF-generated, subscriber-related query is received, subscriber information is gathered related to the CSCF-generated, subscriber-related query from at least one subscriber information database using a native protocol of the subscriber information database, a reply message for the CSCF-generated, subscriber-related query is generated based on the gathered subscriber information and the reply message is forwarded to a respective CSCF that generated the CSCF-generated subscriber-related query, the reply message being forwarded according to the AP protocol.

A method for connecting an externally accessible shared serial port to one of a plurality of target serial ports is provided. The target serial ports are associated with a plurality of different application cards within a shelf assembly. The method includes receiving, from an external device connected to an externally accessible shared serial port, a request for a connection between the externally accessible shared serial port and one of a plurality of target serial ports within a shelf assembly associated with a plurality of different application cards, and determining whether shelf resources are available to connect the externally accessible shared serial port to the requested target serial port. In response to determining that shelf resources are available, the externally accessible shared serial port is connected to the requested target serial port.

Methods and systems for providing management in a telecommunications equipment shelf assembly using a shared serial bus

An electronic shelf assembly includes a frame having a plurality of card slots arranged in parallel to each other along an axis of the frame and a midplane having a plurality of connectors are arranged to align with the card slots. Conductive traces are connected to predetermined pins of the midplane connectors and provide point-to-point signaling pathways between midplane connectors aligned with different card slots. An application node card may reside in one of the plurality of card slots. The application node card may have an application processor, a disk controller, and an application card connector. The application card connector is adapted to interface with at least some of the pins of one of the plurality of midplane connectors. A disk storage card may reside in one of the plurality of card slots. The disk storage card may have at least one storage media unit and a disk interface connector. The storage media unit is operatively coupled to the disk interface connector and the disk interface connector is adapted to interface with at least some of the pins of one of the plurality of midplane connectors such that some of the conductive traces support communication between the disk controller on the application card and at least one storage media unit on the disk storage card.

Methods and systems for providing off-card disk access in a telecommunications equipment shelf assembly

A device that enables a card to be hot-plugged into a socket on a processor-base machine includes a signal bus arbitrator, a signal bus switch, a power bus switch, a cover plate switch, status signals and a controller. The controller monitors the status signals and other signals from the cover plate switch and the signal bus arbitrator to generate control signals that activate the power bus switch and the signal bus switch to control power and signal transmitting facilities at the socket.

Hot plug subsystem for processor based electrical machine

A frame for inserting and/or removing circuit cards from the housing of a machine includes a circuit card carrier connected to a locking CAM slide that is disposed to move within the channel of an actuator bar. A slot with a locking feature is fabricated on the locking CAM slide. A pin extending from a surface of the actuator bar into the channel coacts with the locking mechanism to lock the actuator bar relative to the locking CAM.

Device for inserting circuit cards into electrical machines

Hot plug of adapters using optical switches

The device includes a universal carrier plate with openings for cooling attached circuit boards and openings for coacting with brackets to mount different size circuit boards. A positioning mechanism is connected to the universal carrier plate and rides on tracks in the housing to position the carrier plate and its attached circuit board.
