Abstract: A modem parameter required for a modem apparatus is stored in a memory for each telephone number of a communication destination in advance based on past communications. At a communication time, a receiver side is notified of an execution of the short protocol by a QTSD signal, and sequentially a QINFO signal that includes the modem parameter is transmitted. Since the modem parameter is received by the communication destination, the pre-protocols such as exchange of parameter, etc., are shortened so that communication time can be shortened. Moreover, since the transmission of modem parameter is repeated until it is confirmed that the communication destination receives the modem parameter, occurrence of communication errors can be avoided so that the shortened pre-protocols can be surely executed.

Abstract: A DSL modem apparatus provided at a transmission side in an upstream performs upstream communication using carrier indexes of the same range as a downstream. During an echo canceller learning period, a transmission signal is outputted to a line, via notch filters that cut the signal at a frequency location of a PILOT signal of the downstream. An echo signal is received via notch filters and a coefficient is set by calculating from the training signal of its own apparatus and the echo signal.

Abstract: A MODEM can shorten the processing time of an interface disposed between a data terminal equipment (DTE) and the MODEM. The MODEM stores an object program of a procedure in a memory and switches an operational mode of the MODEM automatically corresponding to the prescribed procedure thereby executing the procedure corresponding to the current operational mode. The MODEM further comprises a timer which monitors the transits time between a completed procedure and the next procedure, and the MODEM starts the process of a specified operational mode based on a mode-setting-instruction of the procedure as well as monitoring the transitions time by using the timer, and executing a next specified operational mode when the timer times out, thereby allowing the MODEM to perform the various operational mode switches.

Abstract: In an ATU-R having established a connection with an ATU-C and being in a state where data communication is enabled, the ATU-R being located at a user's home, a voltage detection circuit detects a connector voltage of a connector to which a network cable of a user side is connected. When the connector voltage is decreased below a predetermined value in a state where power is supplied to an ADSL circuit of the ATU-R, the power supply to the ADSL circuit is stopped while maintaining a function related to detecting the connector voltage and controlling the power supply. The connector voltage is monitored even after the power supply is stopped. When the detected connector voltage becomes greater than the predetermined value, the power supply to the ADSL circuit is resumed.

Abstract: A processor executes an initialization sequence that exchanges predetermined signals prior to data communication. A complex operation circuit multiplies transmission data of a sub-carrier by gain compensation data and phase angle compensation data, which are prepared for the same sub-carrier. Therefore, modulation is done so that the multiplication results are simultaneously transmitted, by an IFFT unit, in a plurality of sub-carriers. In addition, the transmission data of a sub-carrier, during the data communication, is multiplied by gain compensation data and phase angle compensation data, which are prepared for the same sub-carrier.

Abstract: A processor of a transceiver estimates a communication distance to an opposing ADSL modem apparatus by detecting a reception level of a communication distance detecting signal in accordance during an initialization sequence with the ITU-T regulated G.992. 1 or G. 992.2. The communication distance detecting signal is used to detect a communication distance to an opposing ADSL modem apparatus and has comb-shaped frequency characteristics. Based on the estimated communication distance, and by referring to a table showing attenuation of signal energy (stored in a RAM), the signal energy in a high frequency band (among the signal energy assigned to transmitting signals) is concentrated into a low frequency band during the communication.
