Patent number: 7995609Abstract: One embodiment of the disclosures made herein is a method for facilitating prescribed application functionality via a network element adapted for providing Digital Subscriber Line Access Multiplexing (DSLAM) functionality. In accordance with such a method, a first functionality server implements server-specific functionality whereby information associated with the server-specific functionality is generated. In response to implementing the server-specific functionality, information in a universal interface format is transmitted for reception by a first access server from a first functionality server. The first access server is connected between the network element and the first functionality server. After receiving the information, the information is translated from the universal interface format to a system-compatible interface format. The translating is performed by the first access server and the system-specific interface format is different than the universal interface format.Type: GrantFiled: November 14, 2007Date of Patent: August 9, 2011Assignee: Alcatel LucentInventors: Stefan Keller-Tuberg, Josh Bailey, Eric Jaramillo

Publication number: 20100195648Abstract: A method is provided for implementing multicast control in a point-to-multipoint tree. In accordance with such method, an operation is performed for receiving a request for translating a network element interface identifier associated with an access multiplexer from a positional port location interface identifier to a system readable interface identifier. The request is transmitted for reception by the access multiplexer from an Internet Protocol (IP) Gateway. An operation for translating from the positional port location interface identifier to the system readable interface identifier is performed after receiving the request, followed by an operation being performed for informing the IP Gateway of the translated interface identifier. Thereafter, an operation is performed for receiving a request for creating a designated root of a point-to-multipoint tree.Type: ApplicationFiled: December 16, 2009Publication date: August 5, 2010Inventor: Stefan Keller-Tuberg

Patent number: 5768496Abstract: A microprocessor fault logging arrangement includes a detector for detecting hardware and software faults 3, 4, 8, which produce an interrupt signal which is applied to the non-maskable interrupt input NMI of microprocessor 1 and, which is also applied via delay circuit 5, to the RESET input of microprocessor 1. The NMI input causes microprocessor 1 to store the state of selected system parameters in a log of fault records stored in a non-volatile memory 2, the selected parameters being stored for fault analysis each time an NMI input signal is generated interrupt signal is applied to the NMI input. The delay circuit 5 allows sufficient time for the selected parameters to be stored in the non-volatile memory 2 before the microprocessor is reset.Type: GrantFiled: January 17, 1995Date of Patent: June 16, 1998Assignee: Alcatel Australia LimitedInventors: Rosemary Lidgett, Stefan Keller-Tuberg, Vinay Deo, Joseph Nour, Peter Field
