Patent number: 7173944Abstract: A digital subscriber line (DSL) communication system that utilizes the high frequency band of a standard telephone line does not require the use of a plain old telephone service (POTS) splitter in the resident's home, which provided isolation between the POTS frequency band (0 to 4 kHz) and the DSL frequency band. A digital subscriber line modem utilizes either constant envelope modulation or quadrature amplitude modulation for outputting DSL signals upstream to a central office. When a telephone in the resident's home is detected as being off-hook, then the constant envelope modulation is used by the DSL modem in order to lessen the intermodulation product distortion that results in audible noise heard by a user of the telephone. When the telephone is on-hook, then another type of modulation, such as QAM, is used to maximize the upstream data rate capability in the DSL frequency band, since any noise generated by the QAM is not a problem due to the non-use of the POTS frequency band.Type: GrantFiled: April 11, 2000Date of Patent: February 6, 2007Assignee: Conexant Systems, Inc.Inventors: Kenneth D.

The data rate of the data for a service can fluctuate greatly and/or rapidly over time (high dynamics), or may fluctuate only a little and/or slowly (low dynamics). The data for the services are transmitted via a common physical channel, with in-band signaling being used for signaling the transport format for the services with high data rate dynamics, and with signaling in a separate channel being used for the services with low data rate dynamics.Type: GrantFiled: November 25, 1999Date of Patent: September 12, 2006Assignee: Siemens AGInventors: Christoph Mecklenbräuker, Michael Benz, Anja Klein, Reinhard Köhn, Jörn Krause, Christian Menzel, Enric Mitjana, Erik Newton, Martin Öttl, Dave Randall, Armin Sitte, Jean-Michel Traynard, Thomas Ulrich

Patent number: 7075952Abstract: The invention relates to a multiplexing method used in a PDH network. Standard PCM signals are received in the network element, at least some of which are multiplexed on a time-division basis into the same outbound transmission frame, the capacity of the payload portion of the frame substantially corresponding to the capacity required by N PCM signals. In order that ATM cells may be transferred more advantageously than heretofore through an existing PDH network, the multiplexing is implemented as configurable in such a way that the total capacity of the payload portion cab be divided between at least two parts of variable capacity in such a way that each part can be allocated a desired portion of the total capacity of the payload portion in accordance with the current transmission requirement.Type: GrantFiled: October 27, 2000Date of Patent: July 11, 2006Assignee: Nokia CorporationInventors: Esa Torma, Harri Lahti

Patent number: 7068684Abstract: An information handling system comprises a TCP/IP network connecting a hub to a multimedia server and the hub to a data server, and the hub to an IP telephony device that is then coupled to a network device. Data sent from the network device is addressed for transmission to the data server and is transmitted through the IP telephony device to the TCP/IP network. The IP telephony device monitors when an amount of data being received over the network falls below a predetermined threshold. If this occurs, the IP telephony device will send a signal to the multimedia server, which will then generate a congestion signal to send to all or selected IP telephony devices in the network to throttle data being received by the IP telephony devices from their respective connected network devices.Type: GrantFiled: February 1, 2001Date of Patent: June 27, 2006Assignee: Estech Systems, Inc.Inventors: Eric G.
