3.3 Local Site Trunking
This mode is also called as Fallback Mode and it allows more than one radio from the same site to communicate
when the link between the site and the network central controller fails. Entering and exiting Local Site Trunking
(that is, returning to System Wide Services) is done automatically. In this mode some services are unavailable.
Your service provider can disable this mode.
