Abstract

PURPOSE:To eliminate need for jumpering in an MDF by providing a digital oscillator circuit generating a digital charging signal in a subscriber circuit. CONSTITUTION:The digital oscillator circuit 10 generating the digital charging signal is provided in the subscriber circuit. When a control signal to send the charging signal is given from a charging signal transmission circuit 20, a gate 50 is opened and a charging signal from the digital oscillator circuit 10 is inputted to a CODEC 30. The CODEC 30 converts the received digital charging signal into an analog signal and sends it to a subscriber terminal equipment 70 through a BSH circuit 40. Through the constitution above, the wiring is simplified more in comparision with a conventional constitution where the charging signal generating circuit is connected to the subscriber circuit via the MDF. Moreover, excess space for the charging signal generating circuit is not required.
