20080205609 | METHOD, SYSTEM AND APPARATUS FOR ADJUSTING THE TRANSMIT POWER OF THE DSL TRANSCEIVER - A method, system and transceiver for adjusting the transmit power seamlessly, which comprises: acquires the noise margin of the received signal, and compares the acquired noise margin with the threshold of the noise margin; when the noise margin of the signal has continually exceeds the threshold of the noise margin for a predetermined period, the noise margin is adjusted to the target range of the noise margin by adjusting the signal transmit power. Therefore, the technique scheme could adjust the transmit power of the transceiver with the varying of noise margin, which ensures the stability and the low error rate of the data transmission and reduces the crosstalk of the line by minimizing the transmit power of the transceiver. | 08-28-2008 |

20090285373 | METHOD FOR USING DIGITAL DATA NETWORKS FOR THE TRANSMISSION OF DATA VIA VOICE CONNECTION PATHS - A method for reducing bandwidth when transmitting data between a sending terminal and a receiving terminal over a voice connection path using a digital data network. The coding of user information is converted within the digital data network between data transmission in the voice connection path and data transmission in the digital data network so that the user information is transmitted on one section of the digital data network via the coded voice connection path and the user information is transmitted on another section of the digital data network using a method suitable for the digital data network. | 11-19-2009 |
20110164735 | EFFICIENT TRANSMISSION OF AUDIO AND NON-AUDIO PORTIONS OF A COMMUNICATION SESSION FOR PHONES - In one embodiment, a server may obtain source data for a communication session having a combined audio portion and non-audio portion. As such, the server may actively split the audio portion of the communication session from the non-audio portion of the communication session, and then provide the audio portion (to a first set of one or more phones) over a phone channel and the non-audio portion (to a second set of one or more phones) over a separate data channel. The second set of phones may then obtain and merge the audio portion from the phone channel and the non-audio portion from the data channel to reestablish the full communication session. | 07-07-2011 |
20130142319 | Method In A Communication System - A method and arrangement are disclosed in a Vector Control Entity for enabling a fair bit rate distribution among lines of similar priority in a vectoring group, when applying partial vectoring in a DSL communication system. The method comprises calculating a rate balancing metric, RBM, for each line i within a priority group A, indicative of the ratio between the bit rate of a line i with a current vectoring resource allocation, and the estimated bit rate of line i assuming approximately no crosstalk within the vectoring group. The method further comprises allocating partial-vectoring resources to the line/s within the group A, based on the calculated RBMs, such as to reduce the difference in RBM between the lines. The method further comprises calculating an updated RBM for any line within the group A subjected to changes in vectoring resource allocation. The method may be iterated until certain criteria are fulfilled. The arrangement is adapted to enable the performance of the above described method. | 06-06-2013 |
20130208876 | ADJUSTING A POWER ALLOCATION OF USERS IN A DIGITAL SUBSCRIBER LINE ENVIRONMENT - A method and a device adjust a power allocation of users in a digital subscriber line environment. An intermediate power allocation is determined for at least one user initializing with the digital subscriber line environment based on a new power allocation determined for the digital subscriber line environment containing the at least one user. The intermediate power allocation provides a predefined minimum signal-to-noise ratio margin for the active users of the digital subscriber line environment. Furthermore, a communication system can contain such a device. | 08-15-2013 |
20150124948 | METHOD AND APPARATUS FOR MANAGING LOW POWER MODE IN XDSL SYSTEMS - According to certain aspects, the present invention provides methods and apparatuses for managing a low power mode in xDSL systems, and more particularly directed to a L2 mode exit procedure for VDSL systems that is robust and quick. In embodiments, parameters for exiting a low power mode are communicated between upstream and downstream modems before the low power mode is entered. According to certain aspects, these parameters include configurations for incrementally exiting low power mode in a plurality of stages. Embodiments of the invention include quickly estimating SNR at one or more stages of this plurality of stages. Additional or alternative embodiments include reliably signaling the beginning of low power mode exit. According to certain aspects, such signaling can include a synchro sequence of inverted and normal sync symbols. | 05-07-2015 |

20160165061 | SYSTEM AND METHOD FOR SECURE TRANSMISSION OF DATA SIGNALS - A call processing system comprises first and second interfaces configured to selectively pass voice signals and data signals between caller and agent to enable communication. An attenuation means is configured to selectively attenuate voice and data signals passing from the first interface to the second interface to impede the agent from receiving voice and data signals from the caller. While a string of discrete data signals is received at the first interface, the system is configured to operate exclusively in each of: a first mode in which voice and data signals are permitted to pass from the first interface to the second interface to enable the agent to receive them from the caller; and a second mode in which the attenuation means attenuates voice and data signals passing from the first interface to the second interface to impede the agent from receiving them from the caller. | 06-09-2016 |
