A quick video showing how a digipeater works. The TH-D72 is configured to send a packet via TEMP-1-1, and the TM-D710 acts upon the packet. You can see the TH-D72 send the packet, the TM-D710 receive the packet, then the TM-D710 send the packet, the TH-D72 receive the packet, and then indicate that it heard it's own packet being digipeated.
