Remote Commands and Error Codes 5-13
Security Commands
To prevent unauthorized access to the CM601 over telephone lines or other
remote-access methods, the CM601 has built-in security for the remote port.
Security is disabled by default. When enabled, remote users must enter a login
command with a valid password before they can access other remote commands.
A timed logout command, based on inactivity, can also be issued. If no activity
occurs on the remote port for a specified interval, users are automatically logged
out. Any attempts to access the port without a valid login will return an
ER 7
error code. The following commands are used to implement CM601 remote
security features:
LGE – login enable
LGN – login
LGT – logout
LIT – set inactivity logout time
LPW – login password
There is no process to identify a password if it is lost or forgotten. Instead the
initialize modem
IN 9346
command must be issued. This command resets the
password to the default and it also resets all modem parameters.
TTD Ternary Transmit
Data Rate Config (NV) 4800 to 512000 bps 0 Issues all appropriate transmit data rate
commands to all option cards in the ternary
transmit data path; accounts for any overhead
added by a module to the data stream; return
value: 0 = no data rate entered for macro or it
no longer reflects system Tx or Rx data rate.
TTP Ternary Transmit
Path Config (NV) Consists of entry slot, data slots,
and exit slot for data path. — Sets ternary transmit data path.
VBM Verbose Mode Config (NV) 0 = disabled
1 = enabled 0 Displays returned ER messages with brief
description; when enabled for advanced
configurations, displays the current active path
as a part of response.
VF View Faults Fault — — Displays stored fault history as card-by-card list
with detailed fault descriptions per card; same
fault descriptions are used by the VFT and FL
commands; supported in ASCII mode only.
VFT View Faults With
Time Stamp Fault — — Displays first 10 faults since faults were last
cleared; faults display with time and
descriptions; supported in ASCII mode only.
VS View Current Fault
Status Fault — — Displays real-time fault conditions with
descriptions in a card-by-card list; supported in
ASCII mode only.
VST VSAT/SCPC
Operating Mode Config (NV) 0 = SCPC
1 = VSAT 0 Sets the modulator and demodulator to operate
independently.
UBT Unit Backplane
Type Monitor ? — Displays the type of unit; response values are:
0 = CM701, 3 = CM601, 4 = CM703,
5 = CM601 with front panel functionality
1
BMonitor commands refer to BERT monitor commands that are available when an option card containing built-in BERT functionality is installed and enabled.
