Display Line Description
Top Line
• Transmit Frequency and Data Rate
(NOTE: Due to space limitations, the resolution of displayed frequency is limited to 1 kHz,
and data rate to 10 bps)
• FEC Encoder type (VIT = Viterbi, VRS=Viterbi + Reed-Solomon, TCM = Trellis Coded +
Reed-Solomon, TUR = Turbo, UNC = uncoded)
Bottom Line
• Modulation type (Q = QPSK, OQ= OQPSK, B = BPSK, 8P = 8-PSK, 8Q = 8QAM,
16=16-QAM)
• Code Rate (Unc = Uncoded, 2144 = 21/44, then 5/16, 1/2, 2/3, 3/4, 7/8, 0.95)
• Scrambler state (S = Scrambler on, N = Scrambler off, I = IESS-315 On)
• Clocking Mode (INT = internal, EXT = external, LOP = loop, CXE = internal & Clock
Extend TxLock E1 mode, CXT = internal & Clock Extend TxLock T1 mode)
• Output power level
• Transmit output state (ON = on, OF = off, EO= external off, RT= Rx-Tx Inhibit)
• TSI state (I = Transmit Spectral Inversion on, N = off)
