Patent number: 8743913Abstract: A distributed DSLAM, which comprises a head end subsystem located within a switching facility and a remote subsystem located outside of the switching facility. The head end subsystem is operative for routing streams of data from a data network to the remote subsystem over a communication link, while the remote subsystem is operative for transmitting over a set of local loops analog signals comprising digitally modulated versions of the data. Separating the routing and modem functionality between inside and outside plant facilities reduces heat dissipation in the outside plant, leading to increased reliability. Flow control can be performed in the upstream and downstream directions by transmitting portions of individual packets and withholding other portions of individual packets. This is done instead of withholding the transmission of entire packets. As a result, the perceived impact on video quality, for example, is lessened.Type: GrantFiled: March 23, 2011Date of Patent: June 3, 2014Assignee: Telekom Malaysia BerhadInventors: Azrin Bin Aris, Siti Sawiah Binti Ramli, Muhammad Fahmy Bin Khyasudeen, Tet Hin Yeap

Patent number: 8660146Abstract: A multiplexer/demultiplexer (MUX/DEMUX) system for multiplexing and demultiplexing information from a plurality of traffic channels is configured according to a Plesiochronous Digital Hierarchy (PDH) standard into a composite signal transferred to and from a telecommunciations interface. A PDH traffic interface receives PDH channel signals from a plurality of PDH channels and a bit-pipe interface receives bit-pipe traffic transported as a packet data stream. A composite signal generation module and interface then creates, outputs and receives a single composite serial data stream including, in a single composite format, information from the received PDH channel signals as well as the packet data stream. The rate of the bit-pipe traffic may be adaptively modulated as a function of the composite rate.Type: GrantFiled: January 15, 2008Date of Patent: February 25, 2014Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Arild Wego, Pål Longva Hellum

Patent number: 8644335Abstract: An access node such as an OLT or DSLAM for use in a communications network. The access node performs a plurality of functions using in a number of function modules, each divided into one or more sub-modules. The status of the sub-modules is controlled by a controlled by a controller that reviews load statistics and other inputs and determines whether the configuration of the function module should be changed. If so, individual sub-modules are powered down, clock-gated, or returned to operational status. A traffic dispatcher positioned before each function module distributes the data traffic to available sub-modules for processing, after which it is aggregated by a traffic aggregator and passed on to the next stage. A number of circuit boards may be used, each containing only one or two function modules. The boards are connected by short, high-speed serial lines, which may have multiple links whose status may also be controlled.Type: GrantFiled: September 29, 2011Date of Patent: February 4, 2014Assignee: Alcatel LucentInventor: Hungkei K.

Patent number: 8638727Abstract: The present invention relates to uplink transmissions and scheduling of resources for uplink transmissions in connection with packet switched communication. A radio communication network schedules (301) time slots for transmission of bursts of a first radio block on at least two different uplink packet data channels and transmits (302) an Uplink State Flag, associated with a mobile station for which the first radio block was scheduled, on a first downlink packet data channel representing a first subperiod within a basic uplink period. The mobile station receives (303) the Uplink State Flag, identifies (304) the scheduled resources for transmission of the first radio block wherein the timing of the first subperiod is derived utilizing the fact that the Uplink State Flag was received on the first downlink packet data channel and transmits (305) the first radio block utilizing the identified resources.Type: GrantFiled: November 1, 2005Date of Patent: January 28, 2014Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventor: Peter Bjórken
