2. 2 Technical characteristics  Product: RT 1110-20-05  operating temperature range ( -20  + 55)  C  SIM card 3.3 v - active (supply by EDC)  SIM and the SMSC are supplied by the same GSM provider  permanent allocation on the wagon (fixed assembly)  Vibration: EN50155 compliant  Shock resistance: EN50155 compliant  Waterproof : IP65  EMC: according to EN50155 and CE  Dimension: outer dimensions 253 x 243 x 145 mm  Weight: 5750 g  MTBF (mean time between failure 50.000 hours)

3. 3 Technical characteristics  Power supply duration 5 years  Type of batteries: not rechargeable, Li batteries  Internal shocks in the direction of shock sensor: the traffic (for example by shunting) > 23,5 m/s2 (approx. 2,4 g)  Internal memory: 384 Kbyte for user data  Antennas integrated into housing  Satellite-based GPS tracking module  Tracking accuracy < 20 m according to assembly position

4. 4 Technical characteristics  GSM mobile radio data module 900 MHz module  Transmit power 2 W (class 4)  SMS (Text/PDU-Mode MO, MT) and SMS-Cell-Broadcast  Housing  Construction: round steel body with welded bottom with firmly placed synthetic domed cap  Material of body: steel ST37, wall thickness 4,5 mm, powder- coated surface  Maintenance-free over 5 years

5. 5 Functions  status of the wagon (loaded / unloaded).  shock detection (in the sense of shocks caused by shunting)  Position tracking by GPS  wagon speed and direction are calculated in the OBT and are sent to the ground station (but only on request -polling)  alarm of low charge battery (two thresholds according to the remaining operating time of less than 8 % and 4 %, respectively)

6. 6 Functions  The OBT exchange messages via SMS to the Ground Station and a software update to the OBT via GSM data channel.  The OBT should be characterised by a unique identifier (SIM identifier and Serial number)  The OBT is individually configurable.  The OBT can run in three different modes (active mode, sleep mode, time table supervision mode) and is able to switch automatically from active mode into the sleep mode.

7. 7 Functions  The SMS sending interval cannot be determined according the moving status of the wagon. The interval depends on the actual OBT mode (active mode, sleep mode, time table supervision mode).  A deviation from the reference of loading status can automatically be reported to the Ground Station during time table supervision mode.  Running / no running is detected during time table supervision mode.

8. 8 Functions  OBT can load 128 way-points. Each one consists of 2 wake-up times, tolerance radius and target status for the sensors. The time table supervision function is time-controlled. A special target detection feature is available only for the final station of the time table in case of delay. This is an internal OBT function which roughly calculates the expected time of arrival (ETA).
