20150139287 | METHOD FOR INITIATING A NON-STANDARD MODE FOR AN XDSL TRANSMISSION SYSTEM AND RESIDENTIAL GATEWAY USING THE METHOD - The invention defines a method for providing an xDSL broadband transmission service between a central office and a customer premises equipment which comprises the steps: initiating a handshaking procedure between the central office and the customer premises equipment, determining an xDSL transmission standard for providing the xDSL broadband transmission service, utilizing a non standard information field during the handshaking procedure to indicate a support of a non-standard mode between the central office and the customer premises equipment, and initiating the non-standard mode, in case no synchronization is established between the central office and the customer premises equipment after the handshaking procedure. | 2015-05-21 |
20150139288 | METHOD FOR PASSING SIGNALS THROUGH A MEDIUM UNDER MONITORING - The method for passing signals through a medium under monitoring consists in generating a reference signal, transmitting this reference signal in a forward direction through the medium under monitoring by means of at least one transmitting electrical circuit, receiving the signal passing in the forward direction through the medium under monitoring by means of at least one receiving electrical circuit, transmitting the generated reference signal in the reverse direction through the medium under monitoring by means of the at least one receiving electrical circuit, receiving the signal passing in the reverse direction through the medium under monitoring by means of the at least one transmitting electrical circuit and thus ensuring the passage of signals through the medium under monitoring. The method for passing signals through a medium under monitoring ensures the production of signals passing through the medium under monitoring which have a high degree of identity. | 2015-05-21 |
20150139289 | RECEIVER, SYSTEM INCLUDING THE SAME, AND CALIBRATION METHOD THEREOF - A receiver includes a fixed delay unit configured to delay a first clock signal received from a clock channel by a predetermined time and output a second clock signal; a first delay unit configured to delay the first clock signal in response to a first control signal; a first data sampler configured to sample a data signal received from a data channel in response to an output signal of the first delay unit and output a first data signal; a second delay unit configured to delay the first data signal in response to a second control signal and output a second data signal; a second data sampler configured to sample the second data signal in response to the second clock signal; and a delay controller configured to output the first control signal and the second control signal. | 2015-05-21 |
