often an issue on the railways! The Modula II GSM-R call station offers the perfect solution.

2. Wireless, Dependable Data Transmission
The Modula II GSM-R, transfers communication and data via GSM and GSM-R. The reliability of these
wireless solutions is demonstrated by multiple security features:
 GSM Quad-band technology 850/ EGSM-R 900 / 1800 / 1900 for voice and data connections.
(Backup can be provided with a secondary SIM card on another GSM network)
 eMLPP(Enhanced Multi-level Precedence and Pre-emption); call prioritisation can be defined for
each call target
 Redundant message transmission via text message (SMS) if the voice channel cannot be
established
 Integrated voice recording for local output of audio announcements: instructions, reassurance
messages, general information, etc.
 User-definable configuration of multiple numbers, with call priority per number for each call key
and LED for visual display of call status
 Sabotage detection automatically triggering a call if an attempt is made to break open or
dismantle the device
 Status reports are regularly sent from the call station. Frequency of the messages is configurable
 A periodic self-test of all main components quickly identifies possible malfunctions.
System Overview
Routing calls over the GSM-R or GSM network the Modula II GSM-R call stations can be fully integrat-
ed into the NIS-Rail communication platform, this offers additional functions such as CCTV images of
incoming calls, regular monitoring of call stations, and centralised configuration of call stations.
Multiple Benefits
 The following features make the Modula II GSM-R call station particularly attractive:
 Thanks to GSM-R technology, intelligent power management and a solar power supply, the
Modula II call station is completely independent of fixed-line networks
 With versatile configuration options, the Modula II call station functions can be tailored to meet
the customer requirements
 A robust IP65 rated enclosure guarantees reliable operation even in
 a harsh environment
 The NIS-Rail Management-Suite is available to configure, operate and monitor Modula II GSM-R
call stations
 Key parameters can be configured and modified by text message
