5.90 Operating Manual 6175.4760.02 – 01
5.4.1.3 Prerequisites
In order to transmit and receive messages over Message Service, the following requirements
must be met:
• A Message Service type (alert messages and/or SDM messages) must be activated via
R&S RNMS3000 (radio network management system) and
• IP_DATA or VOICE_O_IPD must be selected as active Service Group (in ALE 3G (au-
tomatic link establishment 3
rd
generation) the Link Mode xDL (ARQ protocols, x = H or
L) and the xDL Port IP must be selected) and
• the radio needs to be synchronous with its waveform specific network and
• a valid IPoA net must be configured in R&S RNMS3000 (regarding IPoA addresses,
IPoA (IP over air) operation mode, routing tables plus an appropriate waveform data
rate).
5.4.1.4 IP-Based Interface for External Applications
The Message Service provides an IP-based interface for external applications to receive and
transmit messages.
5.4.1.5 Message Addressing
The predefined alert messages are broadcast to all stations in the network.
It is possible to send SDM messages
• to a single message recipient within the current radio network (unicast addressing).
• to every radio within the current network (broadcast addressing).
5.4.1.6 Participant Selection List (R&S M3TR only)
The alert messages can only be broadcast. Due to this, the description below is related to
SDM messages. The selection list for the addressable participants supports the selection of
• a single GPS participant (point-to-point)
• all GPS participants (broadcast).
After a command softkey is pressed, the user is presented with a selection list of
R&S RNMS3000 configured radios participating in GPS reporting:
