PURPOSE:To facilitate a plural metering when a called subscriber answers, by generating metering pulses while discriminating the metering pulses required in band by band with regard to the plural metering system of an automatic swichboard when the called subscriber answers. CONSTITUTION:Calling subscriber SUB acquires originating trunk OGT via main frame F and connects with a party office via junction line LINE. At this time, marker M transfers band information on the called subscriber to translator KTLR, which develops and sends the information to trunk OGT and then resets as well as marker M. When the called subscriber answers as connections advance, trunk OGT operates call meter MET, which corresponds to the calling subscriber, once for counting up by one. Next, as plural metering (one plus plural metering) when the called subscriber answers ends, a pulse corresponding to the band of the called subscriber is sent from charging pulse transmitter KP to call meter MET. Thus, the plural metering in the answering of the called subscriber is facilitated. |
