Analyzing the radio traffic history of a multicast group

The Radio traffic history chart displays the last multicast downlinks as daily or hourly totals for the last 7 or 15 days. The following line charts are displayed:

Delivery status	Color	Percentage of successful downlink transmissions
Downlink fully sent		100%
Downlink partially sent		≥ 80%
Downlink partially sent		≥ 30% and >80%
Downlink partially sent		<30% Note Downlink partially sent (<30%) is considered if no base station was associated with the multicast group when the multicast downlink was transmitted.
