Abstract
Group identification codes, names of parties to be sent, and telephone numbers of the pagers of the parties to be sent are stored in groups in memory,of a selective pager. 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 telephone numbers and the message are alternately sent to a DTMF signal generation section,, which converts the telephone numbers and the message to DTMF signals. The DTMF signals 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 group call can be implemented without involving laborious operations, such as transmission of the telephone numbers and the message one by one.
