6.12.6 ZoneFail Site Lock
This is an optional feature that can be enabled only by factory programmed. It does not
require any special inputs from the infrastructure to operate. This feature is intended to
prevent some of the confusion resulting from a site controller failure. When this occurs, all
sites go into the Site Trunking mode and radios will be unable to roam normally. The
result is that the various radios selected by a particular talkgroup may be operating on
different sites and are unable to talk to each other (see Section 6.12.2, Site Trunking for
more Site Trunking information).
