摘要：Group identification codes, names of parties to be sent, and telephone numbersof the pagers of the parties to be sent are stored in groups in memory of a selectivepager. At the time of transmission of a message, telephone numbers of a specified group

and a message to be sent for the group are selected from the memory. The telephonenumbers and the message are alternately sent to a DTMF signal generation section ,which converts the telephone numbers and the message to DTMF signals. The DTMFsignals are then converted into acoustic signals by means of a speaker and are

continually transmitted by way of a transmitter of a telephone set. As a result, a groupcall can be implemented without involving laborious operations, such as transmission ofthe telephone numbers and the message one by one.
