Use this menu branch to review information on the modem’s current configuration. The
information provided on these screens is viewable on a read-only basis – no editing is possible.
Use the ◄ ► arrow keys to select a parameter. Press ENTER.
Typical for all nested Info screens, press ENTER or CLEAR to return to the SELECT: Info menu.
6.3.5.1 INFO: All
This screen set allows review and configuration of the modem in its entirety. Once a specific
screen displays, press ENTER to continue through the remaining displays. To discontinue and
return to the CONFIG: menu, press CLEAR.
As it is with the CONFIG: All menu, the availability of information screens is dependent on the
active operational settings.

This screen displays Transmit information as follows:
Display Line Description
Top Line (from
left)
• 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 = TPC, VFE = VersaFEC, ULL = Ultra Low Latency, UNC = uncoded)
Bottom Line
(from left)
• 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)
