2.4 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 occupy 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.
