PURPOSE:To perform multi-address calling with one packet, without changing a packet format, by providing a multi-address calling channel and a multi-address calling channel detector for a communication device. CONSTITUTION:A terminal a11 designates a loop number of itself to a loop number designation area, a communication device name A of the station to a communication device designation area 14, a channel number a1n for multi- address calling of own station to a channel number designation area 15, and transmits a packet written in data to a data area 16. This packet circulates a loop and returns to a device A of the designated area 14. The device A recognizes the end of the multi-address calling of the packet itself with a detection circuit and other communication devices B1-Bn detect the loop, communication device name and channel number and recognize the multi-address calling from the number a11 of the device A. |
