5-10 Remote Commands and Error Codes
MQE Modem Query
Execute Monitor ? — Executes the current modem query list and
returns the first result buffer; this command is
available after you enter a modem query list
with the MQL command.
MQL Modem Query List Config (V) One or more CM601 command
mnemonics, up to 120 characters
separated by commas — Combines multiple queries into single
command; list is executed by the MQE
command.
MQN Modem Query Next Monitor — — Displays the next modem query list result
buffer; when additional data remains in a
modem query list result buffer, the last
character of the first buffer response to the
MQE command is a plus sign (+).
NVO Nonvolatile
Memory Override Config (NV) 0 = normal operation
1 = NV override on 0 Inhibits writing to NV memory when a NV
command is entered.
OM Override Modulator
Bit Time Fault Config (NV) 0 = disables TxIF output
1 = does not disable TxIF output 0 Controls the automatic actions performed by
the modulator upon detection of a transmit bit
time fault.
PC Pure Carrier Config (V) 0 = normal, modulated
1 = pure, unmodulated 0 Forces the modulator to transmit an
unmodulated carrier.
PRD Primary Receive
Data Rate Config (NV) 4800 to 512000 bps 0 Issues all appropriate receive data rate
commands to all option cards in the primary
receive data path; accounts for any overhead
removed by a module from the data stream.
The PRD command represents the data rate
that is output from the active I/O card on the
receive side of the CM601.
PRP Primary Receive
Path Config (NV) Consists of entry slot, data slots,
and exit slot for data path — Sets primary receive data path.
PTD Primary Transmit
Data Rate Config (NV) 4800 to 512000 — Issues all appropriate transmit data rate
commands to all option cards in the primary
transmit data path; accounts for any overhead
added by a module to the data stream. The
PTD command represents the data rate that is
input to the active I/O card on the transmit side
of the CM601.
PTP Primary Transmit
Path Config (NV) Consists of entry slot, data slots,
and exit slot for data path — Sets primary transmit data path.
RC Receive Coding
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 type and rate of FEC decoding performed
by demodulator.
RD Receive Data Rate Config (NV) 4800 to 512000 9600 Sets the data rate that is output by the
demodulator after demodulating and decoding
the receive signal. This rate is the receive data
rate, RT and RD signals, provided at the user
data interface, unless the CM601 is configured
with an SCC or some other intermediate data
processing card.
RDI Receive Data
Invert Config (NV) 0 = true data
1 = inverts data 0 Specifies if data received from demodulator
and sent to the user DTE equipment is inverted
or true.
