Figure 1: Basic Overview of IP FSA System
Additional complexity is added to the system when some capacity for voice alerting the
stations and talk-back communications from the stations is considered. There are two
methods for available for handling voice audio traffic: VoIP over the network or using a
radio channel.

prevents fire station alerts from being delayed by other radio traffic on the repeater.
