IP Site Connect
This feature allows your radio to extend communication beyond
the reach of a single site, by connecting to different available
sites via an Internet Protocol (IP) network.
NOTE: This feature is not applicable in Capacity Plus.
When the radio moves out of range from one site and into the
range of another, it connects to the new site's base station to
send or receive calls/data transmissions. Depending on your
settings, this is done automatically or manually.
If the radio is set to do this automatically, it scans through all
available sites when the signal from the current site is weak or
when the radio is unable to detect any signal from the current
site. It then locks on to the base station with the strongest
Received Signal Strength Indicator (RSSI) value.
In a manual site search, the radio searches for the next site in
the roam list that is currently in range (but which may not have
the strongest signal) and locks on to it.
NOTE: Each channel can only have either Scan or Roam
enabled, not both at the same time.
Channels with this feature enabled can be added to a particular
roam list. The radio searches the channel(s) in the Members list
during the automatic roam operation to locate the best site.
