talkgroup. If the DMO channel is not free, and the incoming call has Emergency priority, then
preemption request is sent.
When the gateway receives a group call addressed to its current selected DMO talkgroup, it forwards
the call on to the respective mapped TMO talkgroup. The DMO radio that initiated the call requires
correct setup for gateway calls (otherwise the call is rejected).
To prevent gateways from switching to background mode due to receiving a radio signal, your service
provider sets up a signal strength threshold. Any signal with strength lesser than the threshold is
ignored and the gateway continues to operate.
When in the background mode, the gateway constantly surveys the DMO channel to determine when it
is free. After 10 seconds of inactivity on the DMO channel, the gateway leaves the background mode.
Gateways roam between TMO sites. To prevent disconnecting an ongoing call due to roaming, the site
switch is delayed until it is no longer in range of the given site.
