Abstract: A system and method for personalizing a generic state machine (GSM) logic structure in order to effectuate individual protocol layer functionality of a high speed link protocol stack at a network node (i.e., an application node) having a plurality of connections. An input event structure including at least a service access point (SAP) and a connection identifier (CID) associated with a select service provider layer is provided to a context switch and control block that is operable to retrieve latest state-specific context information based on the SAP and CID. The GSM logic structure is personalized based on the context information to effectuate appropriate service provider layer functionality. The input event is processed by the personalized GSM logic structure to generate next-state information and an output event vector including SAP/CID data for specifying appropriate destinations (i.e., one or more service user layers).

Abstract: A memory card cooperating with a network interface for receiving data entry and update signals from a database manager via a switch fabric and with a bus interface for outputting data on a system bus disposed in a system shelf, which shelf forms at least a portion of a telecommunications node having a distributed scalable database system. The memory card is operable to contain at least a portion of the distributed database in a high speed, high density memory block disposed thereon, which memory block is coupled to a network interface controller via a first memory interface and to a bus interface controller via a second memory interface. An arbiter is coupled to the first and second memory interfaces for arbitrating data input operations and data output operations with respect to the memory block.

Abstract: An in-car video system with inputs for one or more analog or digital video cameras, one or more of which may be wireless, and having inputs for one or more microphones, one or more of which may be wireless. The system includes circuitry to digitize the input signals, if necessary, merge the data with system status data and compress the resulting data with any algorithm, preferably MPEG-4. A hard disk and/or a digital video tape recorder records the compressed data, and a decompression circuit and active matrix video display and audio channel provide monitoring capability of live video and audio. In some embodiments, a hard disk continuously records all data and archives previously recorded data to tape when so ordered to provide after-the-fact recording capability. In some embodiments, anti-tampering circuitry renders the recorded data tamper-proof, and a local playback circuit allows local playback of either live or previously recorded video.

Abstract: System and method for compensating for DS0 timing source transients, such as may occur during a switchover to a new external reference, is described. In one embodiment, an SFI control signal is monitored for embedded frame position information. When the frame position information is initially detected, a 10-bit frame clock counter is reset to zero. The counter is then incremented using an 8.192 MHz clock. From that point on, each time the SFI frame position information is detected, the value of the frame clock counter is checked. If the counter value is zero, the counter continues to run freely. If the counter value is non-zero and the most significant bit (“MSB”) thereof is zero, the count of the frame clock counter is held for one clock period. If the counter value is non-zero and the MSB thereof is one, the count of the frame clock counter is advanced by a value of two, rather than one, for one clock period.

In addition to standardized connectorization, at least one of the front side connector segments or at least one of the rear side connector segments is provided with additional non-standard connector holes, thereby forming an extra-wide segment. The inclusion of extra contact points in a connector segment allows for supporting an independent signal pathway to carry one or more user-defined signals across the backplane, in addition to the standard bus signals, without sacrificing compliance with the applicable bus standard.
