parameters,
terminal identification and configuration,
transmission and reception frequency
bands, audio-frequency input and output
levels, signal-level percentages for each
service in normal operation or boosting
condition, digital modulation scheme (QAM
or OFDM/OQAM), gross bit rate of the
QAM digital modem, digital ports, fall back/
increase rate, optional analog modules,
external signalling relays, clock and
synchronisms and loops.
❖
Monitoring: Chronological list of alarms and
events, terminal alarms, receive pilot level,
