US Patent:

20030217152, Nov 20, 2003

Filed:

May 15, 2002

Appl. No.:

10/146528

Inventors:

David Kasper - Aliso Viejo CA, US

Assignee:

ADC DSL Systems, Inc.

International Classification:

G06F015/173

US Classification:

709/226000

Abstract:

A system uses a resource locking token to allow various processes to have exclusive access to a system resource. The process that receives the token then requests that a local database be updated/synchronized with a master database. The process continues checking the synchronization status every time it gets the token. When the process receives the token and the synchronization is complete, the local database is accessed and the data is used in accessing the system resource. The token is then returned to the system.

Appl. No.:

10/147116

Inventors:

David Kasper - Aliso Viejo CA, US

Assignee:

ADC DSL Systems, Inc.

International Classification:

G06F015/16

US Classification:

709/227000

Abstract:

A communication system includes a local unit that has a lower data link layer and a session layer running a data pass-through application and a user interface. The data pass-through application lets the data link layer in the local unit pass data through to a remote unit. The remote unit has a lower data link layer and a session layer executing a user interface. When the data link layer detects that the session layer is unstable and/or locked up, the data link layer transmits a disconnect request to the local unit's data link layer. All further user data sent to the local unit's data link layer is routed to the local unit's user interface.

International Classification:

H04L012/28
H04L012/56

US Classification:

370/412000, 375/222000

Abstract:

An apparatus and method is described that allows for improved transmission of EOC data over the EOC channels of communication devices and links, reducing the number of dropped EOC packets and increasing the bandwidth and robustness of the EOC channel. The improved device apparatus and method also allows for the reduction of the overhead of EOC channel error detection and correction on the limited resources of the communication device by aborting a corrupted or blocked EOC packet transmission and automatically resending. The improved device apparatus and method additionally allows the reduction of dropped EOC data packets due to corrupted transmission and the resultant miscommunication and corruption of high-level applications of the communication device, such as operation commands, remote configuration and management programs, and operation displays.

Appl. No.:

10/195236

Inventors:

David Kasper - Aliso Viejo CA, US

Assignee:

ADC DSL Systems, Inc.

International Classification:

G06F017/15

US Classification:

708/422000

Abstract:

A method for correlating an input signal to a signature is provided. The method compares an input stream with a signature element-by-element as the input stream is received. The method restarts the comparison using the first element of the signature when an element in the input stream does not match the compared element in the signature and declares correlation when consecutive elements in the input stream match corresponding elements of the entire signature.

Inventors:

David Kasper - Aliso Viejo CA, US

Assignee:

ADC DSL Systems, Inc.

International Classification:

G06F015/173

US Classification:

709/224000

Abstract:

A watchdog monitors and terminates applications that have been initiated through a data link between a local unit and a remote unit. A data link session is established between the local and remote units. When the status of the data link indicates that the link has been lost, the watchdog process terminates the applications initiated by the remote unit.

Assignee:

ADC DSL Systems, Inc.

International Classification:

H03D001/00
H04L027/06

US Classification:

375/343000

Abstract:

An apparatus and method is described that allows for improved correlation of multiple signatures from an input datastream, reducing the complexity and memory size of the correlation operation by utilization of a multiple sequence indexing correlator. The multiple sequence indexing correlator keeps an index into each signature that indicates how many elements have been matched so that only the remaining portion of each signature must be compared to the input data stream. Because of this, no history of the input datastream is kept and only a small portion of each signature is compared at one time. Additionally, the multiple sequence indexing correlator allows for ease of signature modification or addition, pre-execution of functions, signatures with identical substrings but differing lengths to be detected, wild card signature elements, timeouts to determine signature end, null functions, execution hold off for extended signatures, and keystroke detection.

Inventors:

David Kasper - Aliso Viejo CA, US

Assignee:

ADC DSL Systems, Inc.

International Classification:

G06F011/30

US Classification:

713/200000

Abstract:

A method for initiating an action based on a received signature in an input signal is provided. The method includes receiving elements of the input signal, determining when elements of the input signal match corresponding elements in the signature, and initiating a selected action when a selected subset of the elements of the signature match consecutive elements of the input signal.

International Classification:

G09G005/00

US Classification:

345/736000

Abstract:

A first process communicates to a second process what data will be used to display a graphical user interface element such as a window or screen. The second process determines if the data used to display the graphical user interface element has changed, and, if the data used to display the graphical user interface element has changed, communicates to a third process that the data used to display the graphical user interface element has changed. Moreover, the third process receives the communication that the data used to display the graphical user interface element has changed, and, in response to the communication that the data used to display the graphical user interface element has changed, displays the graphical user interface element.
