GSM-R Operations

The GSM-R function is a dedicated function of
this handheld, specifically designed and
developed for railway-related services. It
needs to be supported by the GSM-R network
and a dedicated SIM card.
Description:
Point-to-point call: Indicates a point-to-point
voice call.
Group call: A group call that allows multiple
listeners but only one speaker at the same
time. The user presses and holds the PTT key
to gain the right to speak, and releases the
PTT key to stop speaking. The listener can
press the PTT key to gain the right to speak
when available. After successfully seizing the
right to speak, the user can do so.
Broadcast call: A broadcast call is similar to a
group call. Only the initiator of the call is
allowed to speak, and does not need to hold
the PTT key. Other users can listen to the call,
but cannot gain the right to speak.
