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 chassis for holding modules including a set of first modules oriented horizontally in the chassis and a set of second modules oriented vertically in the chassis. A midplane is oriented orthogonally to the sets of first and second modules. The midplane has connector pins extending from its first side through its second side. Each of the first modules has a first connector for mating with the connector pins extending from the first side, and each of the second modules has a second connector for mating with the connector pins extending from the second side.

Abstract: An apparatus and method for distributing and activating a new security parameter in a computer network in a non-disruptive manner includes transmitting a new security parameter to the an element in the network, instructing the element to place the new security element in a pending database of the element and activating the new security parameter. The present invention also determines possible conflicts in the computer network.

Abstract: A method and apparatus for achieving a non-disruptive code load that includes assigning an endpoint to a non-disruptive code loading new process, loading the process into a memory location of a system and starting the process, wherein a previous process is instructed to forward all messages on its queue to the new process to where all new signals are processed.

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: 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.
