5-12 Remote Commands and Error Codes
STP Secondary
Transmit Path Config (NV) Consists of entry slot, data slots,
and exit slot for data path. — Sets secondary transmit path.
SWV Module Software
Version Monitor syntax is n:SWV ? where
n = 1, 4, 5 — Displays the card’s software version by slot;
response format: <slot#>:V<version number>.
TC Transmit Code
Rate Config (NV) 0 = uncoded, rate 1
1 = Sequential, rate 1/2
2 = Sequential, rate 3/4
3 = Viterbi, rate 1/2
4 = Viterbi, rate 3/4
5 = Viterbi, rate 7/8 3 Sets the type and rate of FEC decoding
performed by modulator.
TD Transmit Data Rate Config (NV) 4800 to 512000 bps 9600 Establish the data rate that is input to the
modulator for transmission; rate is the transmit
data rate expected at the user data I/O
connector (TT and SD signals), unless the
CM601 is configured with an optional
intermediate data processing card; recommend
using PTD command rather than TD.
TDI Transmit Data
Invert Config (NV) 0 = true data
1 = inverts data 0 Specifies if data received from the DTE by the
I/O card is to be inverted or not.
TIM Real-time Clock Config (NV) 000000 to 235959 — Sets the CM601 real-time clock; time is factory
set to U.S.A. Pacific standard time; no default;
IN 9346 or INF 9346 does not reset values in
NV memory; parameters expressed in two-digit
format - hours, minutes, and seconds.
TIO Transmit Data I/O
Card Config (NV) 0 = data I/O connector on modem
card
1 = corresponds to slot 1
1 if data I/O
card in slot 1 Selects active transmit I/O card by slot number
for CM601 configurations with multiple data
interface cards installed.
TM Transmit
Modulation Type Config (NV) 0 = BPSK
1 = QPSK 0 Sets modulation type for modulator.
TP Modulator Transmit
Power Config (NV) 50 - 250 100 Sets the output power level of the modulator
TxIF in 0.1 dBm steps.
TR Transmit Symbol
Rate Config (NV) 4800 to 512000 sps 19200 Sets the modulator symbol rate; recommend
use of PTD command rather than TR.
TRD Ternary Receive
Data Rate Config (NV) 4800 to 512000 bps 0 Issues all appropriate receive data rate
commands to all option cards in the ternary
receive data path; accounts for any overhead
removed by a module from the data stream;
return value: 0 = no data rate entered for macro
or it no longer reflects system Tx or Rx data
rate.
TRP Ternary Receive
Path Config (NV) Consists of entry slot, data slots,
and exit slot for data path. — Sets ternary receive data path.
TS Transmit
Synthesizer
Frequency Config (NV) 52000 to 88000 70000 Sets the IF carrier synthesizer frequency for the
modulator; changes in increments of 1 Hz.
TT Transmit Timing
Clock Frequency Monitor ? — Displays the frequency of the TT clock supplied
by the DTE to the data I/O connector of the
CM601; parameter accurate to better than ±1
percent of the frequency being measured.
Frequency of the TT clock is expressed in
hertz; if BEN = 1 then ER 4 displays.
