The SIGNUM T 50 test unit is a tool that has been designed in partnership with ENAIRE for the Analysis, Monitoring, Diagnosis and Audio Quality Measurement of protocolos and lines used in aeronautical communications
Used for maintenance, verification and commissioning, assuring the nteroperability and being compliant with the international standars
Compatible with analogue and VoIP EUROCAE ED-137 resources used in ATC Communications
The SIGNUM T 50 can be supplied as a laptop PC or be integrated into a rack Working in analogue (frecuency and time domains) and VoIP protocols according to EUROCAE ED-137 standards
“ The SIGNUM T 50 is the only tool in the market capable of identifying faults and analysing VoIP and analogue communications SIMULTANEOUSLY ”
Operating Modes
- TX/RX Analysis/Monitor Mode.
- Terminal/Emulator mode of a certain protocol.
- Automatic Lines/Systems measurement mode.
- Transmission Line Emulator mode.
- VoIP EUROCAE ED-137 Monitor Mode with data packet decoding represented on a diagram (‘callflow’).
- VoIP EUROCAE ED-137 Terminal/Emulator mode for making and receiving calls.
- Audio Quality Mode.
It is possible to simultaneously receive signals from an analogue channel and data packets from a VoIP channel, so that they share a common time base.
Parameter Measurements
It is also possible to automatically perform various measurements of characteristic parameters of lines and communications systems:
- Attenuation versus frequency.
- Gain versus level.
- Propagation delay.
- Signal to distortion ratio. (dB and %)
- Psophometric noise power.
- Echo characterisation.
- PTT and SQ propagation measurements.
Communication Protocols
In the frequency and time domain, the unit is able to operate with the following communication protocols:
- ATS-R2 Eurocontrol Regulations.
- ATS-N5 Eurocontrol Regulations.
- Spanish Hot Line Regulations (LCEN).
- Analogue Telephony (FXS/FXO/LB).
- Spanish in-band signalling standard: Remote control / Remote signalling (TM/TS).
- Analogue Radio.
- EUROCAE regulations for VoIP systems: Radio and Controller Position (Telephone, IA and Radio calls).
Functional characteristics
- Presentation of signal graphs and call scenario diagrams.
- Manual or automatic storage when certain events occur.
- Automatic or manual signal analysis tools.
- Reception of telephone calls through the handset included in the unit.
- Possibility of taking measurements between: two analogue interfaces, an analogue interface and a VoIP channel, or between VoIP channels.
- Generation of reports in Excel showing the results of the measurements and configurations used.
- Possibility of controlling another unit, or being controlled remotely.
