Multicast host behavior of a DAP

To illustrate the behavior of a DECT Access Point as a multicast host, refer the following table.
It provides a textual representation of the traffic on the DAP network interface.
The following is the sequence of actions:
1. The DAP is powered up.
2. The boot program retrieves update information through DHCP and TFTP (frames
3. The firmware is started, which reinitializes the network stack, retrieves provisioning
4. The DAP joins the multicast group, initiating the sending of unsolicited IGMP join
5. A General Query is sent from the Querier (frame 40).
6. The DAP responds with its multicast group membership report (frame 41).
The IP addresses used in the traffic example are defined in the following table.
