Patent number: 6747977Abstract: To obviate inefficient use of bandwidth in a packetised system, such as a broadband ATM domain, the use or amount of header information sent in relation to a channel is restricted by one of two principal mechanisms, as exemplified in FIGS. 3 and 4. First, control information incident to a packet interface (20) is interrogated by a processor (21) to determine (50) packet length requirements. A packet length indicator is then generated (52) for inclusion within a header (44) of a packet. Alternatively, a frame (30) is pre-partitioned (60) into several packets (32-42) having different lengths. An addressed subscriber unit (28) is allocated (64) a particular channel, i.e. at least one particular packet within the frame (30), based on data throughput requirements (62), whereby the location of the packet within the frame inherently identifies the length of the packet. Optionally, the data rate used within that packet may also be identified inherently by the location of the packet within the frame (30).Type: GrantFiled: November 9, 1999Date of Patent: June 8, 2004Assignee: Nortel Networks LimitedInventors: Roger Smith, Simon Daniel Brueckheimer, Fai Tsang

Patent number: 6714543Abstract: The invention relates to a method and apparatus for multiplexing traffic from a plurality of fixed bit rate sources over an ATM network. The traffic from the fixed bit rate users is multiplexed to form a TDM trunk group which is assembled into AAL2 minicells prior to being converted to ATM cells for transmission on the ATM network. By combining the fixed rate traffic sources into a TDM trunk group and then mapping the trunk group into AAL2 minicells, it is possible to improve efficiency of fixed bit rate traffic transmission using the ATM protocol.Type: GrantFiled: October 25, 1999Date of Patent: March 30, 2004Assignee: Nortel Networks LimitedInventors: Simon Daniel Brueckheimer, David John Stacey

Patent number: 6665300Abstract: Collisions caused by simultaneous allocation of the same channel identifier (CID) to two AAL2 connections over an ATM virtual channel connection between first and second nodes in an asynchronous network are avoided by the use of status records. Each node maintains a record of currently assigned CIDs and compares the CIDs of incoming connection requests with that record. Where the CID of such an incoming request is found to have been assigned, a message is returned to the request originator refusing the connection request. Preferably a set of CIDs is assigned to one node so that, in the event of a potential collision, that node seizes the connection.Type: GrantFiled: May 27, 1999Date of Patent: December 16, 2003Assignee: Nortel Networks LimitedInventors: Keith Caves, Simon Daniel Brueckheimer

Publication number: 20030219087Abstract: A recently received portion of a transmit signal is utilized, and a pitch period of the received signal is determined. Then, the determined pitch period is utilized to search for similarities in the originally transmitted signal. This searching is done over a range of delays. Once the optimal delay is determined, it is then utilized as the delay between the transmitted signal and the received signal. Once this delay is known, the received signal can be time-aligned with the delayed signal.Type: ApplicationFiled: May 22, 2002Publication date: November 27, 2003Inventor: Simon Daniel Boland
