Abstract: A reception result of an analog signal transmitted from a local switch to a subscriber line, or a voltage difference corresponding to a line current is analyzed, and a transmission characteristic in the subscriber line is evaluated based on an analyzing result. The transmission characteristic is sent to a network by use of a function of an analog transmitting unit. Noises having power of a predetermined threshold value or more are detected from a data signal input to a digital transmitting unit, and a periodicity of the noises is examined, whereby influences of the cyclic noises are evaluated, and an examination result is sent to the network by use of the function of the analog transmitting unit. As a result, provided is an xDSL modem capable of automatically collecting various characteristics of the subscriber line connected thereto prior to a start of a provision of a broadband communication service.

Abstract: An ADSL modem connected to the telephone line is disclosed, which even in the case where a plurality of ADSL modems are connected to a single telephone line installed in a SOHO application or in the home of an ordinary user, a stable high-speed data communication can be realized without superposing the signals between the ADSL models or without causing any impedance mismatch. An ADSL band signal detector (11) detects whether the ADSL frequency band is occupied by another ADSL modem connected to the telephone line or not. Upon detection that the ADSL frequency is so occupied, a control unit (12, 13) suppresses the application of the signal energy to the ADSL frequency band.

Abstract: In a signal point arranging method for use with a quadrature amplitude modulator/demodulator device in which a desired number of signal points are arranged on a rectangular plane, a plurality of grid points are first set such that they are symmetrical with respect to the rectangular coordinate axes of the rectangular plane and arranged at intervals of a unit distance. Next, a plurality of concentric circles with their center at the coordinate origin of the rectangular plane are set, each of the concentric circles having a radius equal to a distance between the coordinate origin and a grid point. Then, a desired number of signal points are arranged on points of intersection of the grid points, the concentric circles beginning with the circle smallest in radius and continuing with circles of increasing radius. As a result, each of the signal points can be arranged as close to the coordinate origin as possible, thus enabling the peak power of modulated signals to be minimized. In addition, since the distance between signal points can be held constant, the S/N characteristic does not vary with the signal points and a constant transmission error rate can be secured. As a result, a signal point arrangement is obtained which enables data transmission at minimum required power, reduces transmission error rate and minimizes the S/N characteristic.

Abstract: A multipoint type MODEM communication system having a training device for adapting receiving parameters in a receiving MODEM to a characteristic of a telephone line connected to a sending MODEM in response to a training signal sent from the sending MODEM prior to the reception of data. The training signal includes a tone for gain control, a timing signal for pull-in synchronization, and at least two impulses for equalization and carrier phase control, which are superimposed on each other. A time between the first and the last impulses defines the characteristic of the telephone line which should be adjusted in the receiving MODEM.Additional guard impulses may be added prior to and/or after the impulses. A scramble signal also may be added after the impulses.In addition, a method for training the receiving MODEM is disclosed.
