Abstract: A method for providing an early packet termination such that prior to the complete transmission of the number of cells specified in the first cell of a packet, a crossbar connection is released. The act of releasing the connection is triggered on recognition of an End of Packet bit (EOP) set in any cell of the stream. The feature can be enabled, for example, by a specific act of setting a register bit, connecting a pin to Vcc or ground or some other intentional act. The feature will default to the inactive state upon reset.

Abstract: A method and apparatus for achieving a non-disruptive code load that includes staging the new version of executable code, stacking the hardware events during code copy and code switch over, copying the code into the runtime area, restarting the system upon completion of copying the new code without reinitializing the hardware and processing the stacked hardware events with the same system state (hardware and firmware) information.

Abstract: A system for testing and monitoring the operation of telephone systems uses a call trace method for capturing messages associated with a phone call. The system can provide an indication as to the time a particular triggering signaling message (e.g., IAM or RLC message) was detected on a link. The present system assembles SS7 signaling messages in real-time. Time stamps are employed in triggers to identify past messages stored in a buffer that are related to the phone call.

Abstract: A system for cooling telecommunications device includes an air inducing mechanism which pushes air into an enclosure of the device and an air exhaust mechanism which exhausts the air from the enclosure. The rate at which the air is pushed into the enclosure is less than the rate at which the air is expelled from the enclosure and these two rates are controlled such that the pressure differential between the pressure within the enclosure and the ambient pressure outside the enclosure is minimized. By minimizing this pressure drop, the airflow mechanisms are able to operate more efficiently, that is, they are able to operate at substantially near their design speed.

Abstract: A method of adapting a native ESCON director to provide fibre channel switching capability includes providing a fibre channel port adapter comprising one or more boards that can be installed into slots in a multi-protocol channel switch having a central switch; connecting said port adapter to a Fibre Channel device; wherein said method permits interconnection through said central switch, thereby allowing connection between and exchange of information between any two desired ports

Abstract: An apparatus and method for dynamic resource mapping in a TCP/IP environment that includes a DRM server component, a client side DRM process for collecting machine specific performance characteristics, a client/server protocol to allow communication of machine specific process characteristics between the DRM server component and the client side DRM process and a DRM protocol to allow a client to request an application resource by name and the DRM server to return a selected address of a client, the selection made based upon collected machine specific performance characteristics of at least one client. Furthermore, the invention updates the DRM server to reflect the operability of the application and as a result does not return the address of the resource if it is inoperable.

Abstract: A framework of dynamic link libraries (DLLs) enables an application to perform protocol analysis of messages from multiple protocols. The framework is modular, allowing new protocol-specific modules to be added when analysis of new protocols is required. Analysis of multiple protocols is optionally executed simultaneously.

Abstract: A method and apparatus that recognizes a portion of an address that would be unrecognizable to an intended associated switch or device and manipulates the portion of the address to make it recognizable. The apparatus and method manipulates a discontinuous address to provide the appearance to the associated device, switch or peripheral, that the address is continuous. This provides additional address capacity such that a new address is created within the switch itself for routing data within the switch. All or a portion of the switches in network are preassigned a chassis address, and each chassis also has a specific switch address that is different from the preassigned chassis address. An address adaptor provides translation of addresses and mapping within a switch so that in the event of a port failure, affected frames can be redirected from the failed port by employing the described translation and mapping operations.

Abstract: A message queue server emulates a computer peripheral that not only supports communication between two mainframes, but also provides a gateway to open systems computers, networks, and other similar message queue servers. The message queue server provides protocol-to-protocol conversion from mainframes to today's computing systems in a manner that does not require businesses that own the mainframes to rewrite legacy applications to share data with other mainframes and open systems. The message queue server emulates a mainframe peripheral coupled to a first mainframe having a first protocol. The system includes digital storage to temporarily store information from the first mainframe.

Abstract: The system comprises a first processor, a second processor and non-volatile memory. The non-volatile memory stores messages being transferred between the first and second processors. The non-volatile memory is resettably and logically decoupled from first and second processors to preserve the state of the first and second processors and the messages in the event of a loss of communication or a processor reset. The non-volatile memory increases the rate of message transfer by transferring blocks of messages between the non-volatile memory and the second processor. The non-volatile memory includes status and control registers to store the state of messages being transferred, message queues, and first and second processors. The system may also include a local power source to provide power to the non-volatile memory.

Abstract: An apparatus for regulating the signal termination voltage planes of a system, the signal termination voltage planes having a voltage which is between, or intermediate to, the system's upper and lower power supply voltage planes, and for recovering signal termination energy, which is normally dissipated or otherwise wasted, and for transferring the recovered energy to the system's upper power supply voltage plane, or power bus, for reuse.

Abstract: A device for converting at least four parallel data streams on respective input data lines into one serial data stream on a fiber optic data line. The device includes a first multiplexer for multiplexing at least two of the parallel data streams into a first intermediate output stream and a second multiplexer for multiplexing at least two other of the parallel data streams into a second intermediate output stream. A serializing transmitter is coupled to the first and second multiplexers for serializing the first and second intermediate output streams into the serial data stream. A signal synchronizes the serializing of the first and second intermediate output streams and tags output data in the serial data stream as corresponding to data from each of the respective input data lines. In-band messaging is used to transfer commands and status messages between devices without affecting ongoing data stream communications.
