摘要： A telephone to be connected to a wireline having reduced sensitivity to RF interference over a predetermined frequency range from an adjacent mobile wireless communications device may include a transmit amplifier, a receive amplifier, an audio input transducer connected to the transmit amplifier, and an audio output transducer connected to the receive amplifier. The telephone may further include an RF shield(s) surrounding the audio input transducer and the audio output transducer for reducing RF interference over the predetermined frequency range from the adjacent mobile wireless communications device. Moreover, the telephone may also include at least one RF audio input filter element connected to the audio input transducer and at least one RF audio output filter element connected to the audio output transducer, both of which are also for reducing RF interference over the predetermined frequency range from the adjacent mobile wireless communications device.

摘要： Data acquisition from a touch-surface input unit may be disrupted during the generation of radio frequency (“RF”) pulses. To mitigate this problem, touch-surface data acquisition is temporarily halted during RF pulse generation. Data collected prior to temporarily halting is retained, with subsequently acquired data being added to prior collected data.

摘要： Data is collected and interpreted in response to one or more transmitted signals to determine if an interfering device is present. If an interfering device is present, a message is generated and presented to a user indicating, for example, that the installation of a micro-filter is appropriate. The system can then determine if the micro-filter was installed properly and, for example, commence communication or, if the micro-filter(s) did not solve the problem, initiate communication with or contact a technician.

摘要： Bridge circuit for echo suppression for a reception signal of a communication device connected to a transmission line, to which can be supplied a reception signal received via the transmission line and a transmission signal to be transmitted by the communication device via the transmission line. The bridge circuit is designed such that on balancing the bridge circuit, the reception signal there can be tapped echo-compensated with a transmission signal part generated by the transmission signal being suppressed. To balance the bridge circuit a variable simulation device is provided to simulate at least one circuit section of at least one bridge branch and connect with the at least one bridge branch. By such an arrangement, the signal level in the simulation device may be reduced so far that this can be designed as an integrated circuit and to be programmable.

摘要： Method and system are provided for optimization and transmission of digital signals through twisted pairs of telephone cables. Crosstalk reduction is obtained due to cancellation of electromagnetic fields generated by correlated twisted pairs by establishing mutual pair-to-pair coherence at each tone of a transmission spectrum and introducing a requested phase shift between the tones propagating in different pairs.

摘要： A telephone loop monitoring and isolation device which can be connected to a wireless telephone subscriber unit providing an interface between an analog or digital central station network and the internal telephone wiring of a subscribers premises. The device is also operable with a cable telephone subscriber unit. The device provides passive real time loop status information as well as loop isolation if the voltage across the loop falls below a predetermined level. When normal loop impedance conditions are restored, the subscriber loop is automatically reconnected to the subscriber telephone unit. The device is effective for examining open circuit and abnormal impedance conditions and provides loop status information to the telephone subscriber. The system of the invention also has an alarm enhancement in that it will provide an alarm status indication to a monitoring center, such as a police department or the like, while still maintaining communication capabilities, even during an existing active telephone communication.

摘要： In a communications environment where it is desirable to allow the simultaneous transmission of digital subscriber line (DSL) signals and conventional Plain Old Telephone Service (POTS) signals on a single two-wire communication line, a method and apparatus is configured to automatically measure the distortion caused by a telephone or other attached device such as a dial modem due to the presence of a DSL signal on the same communication line. The method and apparatus of the present invention allows DSL devices and POTS devices to be used on the same communication line without the use of a splitter.
