Appl. No.:

09/584379

Inventors:

Anthony Imperato - Thiells NY
David Reagan Rice - Morristown NJ
Shan Yueh - Bridgewater NJ

Assignee:

Lucent Technologies Inc. - Murray Hill NJ

International Classification:

H04M 124

US Classification:

379 2902, 379 101, 379 22, 379 2201, 379 2204, 379 2601, 379 2901

Abstract:

A method and system for automatically testing E911 systems using digital loop carrier trunks in a laboratory. A testbed running a testing program evaluates the functionality of a digital loop carrier trunk, a channel unit pair, and an E911 switch by measuring a delay and duration of an acknowledgement pulse from the E911 switch in response to an off-hook condition at a simulated PBX. The testbed and testing program also evaluate the functionality of the E911 switch and a simulated PSAP by measuring a delay and duration of a ring signal from the E911 switch in response to an emergency signal sent by the simulated PBX. Once connection between the simulated PBX and the simulated PSAP has been established, the end-to-end signal loss is also measured.

International Classification:

G06F 1300

US Classification:

395872

Abstract:

Data is transferred from a host system to a subsystem connected to the host by a system bus in an efficient manner using one or more virtual first in first out (FIFO) registers in host memory and a corresponding set of virtual FIFOs located in the subsystem memory. A transmission controller controls the transfer of data from the host FIFOs to the subsystem FIFOs while the subsystem processor reads and processes data from the subsystem FIFO. By accumulating data in the host FIFOs before transfer to the subsystem, overhead associated with starting and stopping data transfers over the system bus is substantially reduced.

Appl. No.:

7/926724

Edward M. Ruddick - Woodstock NY

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 314

US Classification:

395163

Abstract:

The data processing system includes processing nodes and a graphics display device for processing a graphics data stream. The data processing system partitions a graphics data stream into a data segments or work groups for processing by the processing nodes. Next, the data segments are distributed for processing to the processing nodes. In response to receiving a data segment at a processing node, the data segment is processed to produce a processed data segment. The processed data segments are recombined into a processed graphics data stream. This processed graphics data stream is coupled to the graphics display device.

International Classification:

G06F 314

US Classification:

395163

Abstract:

In a graphics subsystem, a highly interactive two-dimensional (2D) data stream and a computationally intensive three-dimensional (3D) data stream are processed concurrently in such a manner that processing of the 2D data stream is not held up by processing of the 3D data stream. A 3D geometry subsystem having a parallel pipeline architecture is used to process the 3D data stream, while a 2D subsystem concurrently processed the 2D data stream in parallel with the 3D subsystem. A reordering device couples the processed 2D and 3D data streams to a common raster subsystem. The reordering device, which contains an internal buffer, reorders any order-dependent elements of the 3D data stream appearing at the output of the 3D geometry subsystem in an order different from the order in which they were supplied to the input end. The reordering device prioritizes the 2D data stream relative to the 3D data stream so that elements of the 2D data stream arriving from the 2D subsystem are passed to the raster subsystem almost immediately, without having to wait for elements of the 3D data stream.
