Data Services

Short Data Message (SDM):
A data service that supports a variety of standard formats – Binary Code, Text and GPS.

Status call:
32 preprogrammed status messages can be sent and received. The status call can be used as a trigger for special functions such as ambience listening, remote stun/kill/revive and GPS data delivery.

Transparent data call:
This function uses a dPMR radio as a data modem allowing data communication on a 6.25kHz channel such as for a remote telemetry system or data applications.

GPS data delivery:
Sends GPS position data with Status, SDM and emergency calls. Position data can be used for GPS-based vehicle management applications.

Supplementary Service

Emergency call:
The highest priority type of call. In a dPMR Mode 3 system, the network will attempt to connect this type of call as quickly as possible.

Pre-emptive emergency:
If all traffic channels are busy, this call service clears down the existing call and gives the highest priority for the emergency call.

Ambience listening:
The ambience listening function allows the dispatcher to turn on the PTT from a remote location and transmit anything the microphone hears for a preprogrammed period.

Remote kill:
This function disables a lost or stolen radio over the air, eliminating security threats from undesired listeners.

Remote stun/revive:
The remote stun function temporary locks out a radio until the revive command is received, or the user password is entered.

Call back (Radio function):
Up to ten missed incoming calls can be stored to return the call later.

Call queue:
If a called party or channel is busy, the call queue automatically connects the call when it becomes available.

Digital voice scrambler:
A built-in digital voice scrambler provides about 32,000 codes scrambler for secure conversations.

ANI (Automatic number identification):
The ANI function shows the alias ID number on the LCD while receiving a call, allowing the radio user to identify who is calling.

Late entry:
If a group call is in progress when a member of the group turns on the radio or comes into the radio coverage area, this function shows the caller’s name, and allows the user to join the conversation.
