PURPOSE:To improve the power consumption of a receiver which is terminal equipment and to eliminate the need for a power switch of the receiver by setting a battery saving period. CONSTITUTION:A dial signal is inputted to a trunk 31 through an exchange 2 and further inputted to a register 33. The register 33 once receiving a predetermined number of calls transfers all call numbers converted into BCD numbers to a storage circuit 35. A timing circuit 34 actuates a previous signal generator 37 to send out a previous signal. Then, a synchronizing, an address, and an end signal are outputted successively and then the timing circuit 34 actuates a battery saving switching ringer 39 to send out a one-word battery saving switching signal, and then sends out an end signal. |
