Generic Bus System

View page
US Patent:
6501766, Dec 31, 2002
Filed:
Mar 30, 1998
Appl. No.:
09/050246
Inventors:
Melhem I. Chaar - Gloucester, CA
George F. Irwin - Kanata, CA
James L. Watchorn - Nepean, CA
David A. Fisher - Kanata, CA
Michael F. Kemp - Stittsville, CA
Osama Bahgat - Petaluma CA
Assignee:
Northern Telecom Limited - Montreal
International Classification:
H04L 1240
US Classification:
370458, 370257, 370443, 370462
Abstract:
A communication system consisting of a number of modules that communicate with one another through a shared communications bus which accommodates different protocols. The system includes a bus clock for defining a frame having a plurality of time slots for communicating signals on the bus; and a bus management algorithm for specifying a receive assignment definition and a transmit assignment definition. The receive assignment definition defines a receive channel for each of the modules representing a set of the time slots, where the modules receive signals from the bus during the set of time slots prescribed by the receive channel. The transmit assignment definition defines a transmit channel for each of the modules representing a set of the time slots, where the modules transmit signals to the bus during the set of time slots prescribed by the transmit channel.

Asymmetrical Digital Subscriber Line (Adsl) Downstream High Speed Cell Bus Interface Protocol

US Patent:
6683887, Jan 27, 2004
Filed:
Dec 16, 1999
Appl. No.:
09/465352
Inventors:
Tony Huang - Santa Clara CA
Prakash Appanna - Fremont CA
Jensheng Lee - Petaluma CA
Hamid Baradaran - Novato CA
Hans Christian Mogensen - Petaluma CA
James Lotz - Napa CA
Tom Kwang-Tsai Koai - Fremont CA
Osama Bahgat - Petaluma CA
Assignee:
Alcatel USA Sourcing, L.P. - Plano TX
International Classification:
H04J 316
US Classification:
370466, 370487, 370490, 370506, 370510, 370518
Abstract:
An asymmetrical digital subscriber line (ADSL) downstream high speed cell bus interface protocol allows ADSL cell packets to be transmitted downstream from an ADSL bank control unit (ABCU) to a plurality of ADSL line units at a high rate of downstream throughput with flexible and efficient allocation of bandwidths and reduced error probability. The frame boundaries of an ADSL frame are derived from a conventional subscriber bus interface (SBI) frame for carrying conventional narrowband plain old telephone service (POTS) traffic, thereby allowing the ABCU and the ADSL line units to be implemented in existing channel banks with standard channel bank backplane traces.

Method And Apparatus For Full Range Translation Of Large External Identifier To Small Internal Identifier

View page
US Patent:
62629859, Jul 17, 2001
Filed:
Mar 30, 1998
Appl. No.:
9/050129
Inventors:
Tony Huang - Novato CA
John Edward Vincent - Ottawa, CA
James Leslie Watchorn - Nepean, CA
Paul Fong-Yan Hung - Stittsville, CA
Osama Bahgat - Petaluma CA
Gary Depelteau - Ottawa, CA
James McLaughlin - Nepean, CA
Assignee:
Nortel Networks Limited - Montreal
International Classification:
H04L 1250
US Classification:
370397
Abstract:
Methods and apparatus are described for translating identifiers that are used by computers to reference various entities such as data structures, external objects, or connections in a telecommunications network, from a bulkier less manageable format to a smaller more manageable format. Such translations are carried out to reduce the needless processing and memory demands that are made of a localized set of components when the large identifiers the set receives from other components include fields that none of the members of the set need to access. The invention is centerd around a two-stage look-up method wherein an inputted external identifier is divided into two parts. The first part of the inputted external identifier is used as an address into a first look-up table that contains base-addresses of a second look-up table. The second part of the inputted external identifier is used as an offset-address into the second look-up table. The offset-address and the base-address are combined to access the second look-up table, which contains all the internal identifiers.
