    摘要: To reduce a frequency of recording communication management information for communication disconnection countermeasure. A digital content distribution system includes a license server (101) that issues a license, and a user terminal (103) that controls use of content based on the issued license. The license server (101) judges, according to the license to be issued, whether or not the communication management information for the communication disconnection countermeasure needs to be recorded, and notifies the user terminal of a result of the judgment. This enables the user terminal (103) to reduce the frequency of recording the communication management information.

    摘要: The subscriber circuit has a balanced amplifier and a built-in call-current polarity changing circuit. Moreover, the output stage circuits of the direct feed-back and offset cancel circuits of the subscriber circuit have the same configuration. By switching the input voltage supplied to the direct feed-back and offset cancel circuits by a switch, the signals fed back to the inputs of the balanced amplifier are switched. Thus, the polarity of the loop current can be inverted. Furthermore, it is possible to switch the loop current without adopting an extra circuit, and the part of the circuit in which the switches are not required to withstand pressure can be constructed with CMOS thereby allowing minimization of the circuit size.
