P300H
Average & minimum Eb/No
Average & minimum estimated user BER
Buffer fill status
Average & 1 minute minimum measured BER from PRBS tester (may run
continuously through ESC or Aux channel for continuous traffic quality
monitoring)
View on front panel LCD, Print to rear panel serial port (`D` type) either
all entries or just unprinted entries read over remote M&C bus
Monitor of distant Eb/No & BER only, Full distant Eb/No maintenance, &
Self monitor (broadcast) modes. Unidirectional or bidirectional operation.
Utilises async ESC channel on IBS/SMS, IDR and Closed Net Plus ESC
carriers (ESC from 300Baud, ie overheads down to <1%).
Target Eb/No, Tolerance window, Max & Min delta powers, Slew rate
limit, comms loss action (freeze, max or nominal power).
Automatic logging of distant Eb/No and local AUPC delta power at user
controlled intervals in traffic log.
Automatically interleaves AUPC messages with distant end remote M&C
(if active) on ESC channel.
Independent Max & Min delta powers (ie facility to reduce power & still
maintain quality of service with good atmospherics) allows power
balancing on transponders with traffic to varied destinations.
Interface Loop (local & remote)
Drop/Insert Loop (local)
Framer Loop (local)
FEC Loop (local)
RS Loop (local)
Internal IF Loop (local, Rx IF automatically tuned to match Tx)
Deframer/Framer Loop (remote)
Transmit CW (pure carrier)
Transmit alternate 1,0 pattern (for carrier suppression test)
Disable Reed-Solomon decoder corrections
3 independent changeover contacts:
Prompt Unit fault
Prompt Traffic fault (Tx or Rx)
Deferred Alarm (backward alarm, BER or Eb/No below user set
threshold)
Intel 8032 micro controller provides all M&C functions
