Description of Arguments
to Query
Command or Query.
Alarm mask conditions, in form abcdefghijkl, where:
a=Tx FIFO (0 = unmasked, 1 = masked)
b=G.703 BPV (0 = unmasked, 1 = masked)
c=Tx-AIS (0 = unmasked, 1 = masked)
d=Rx AGC Alarm (0 = unmasked, 1 = masked)
e=Eb/No Alarm (0 = unmasked, 1 = masked)
f=Rx-AIS
g=Buffer slip
h=Ext Reference alarm
i=BUC alarm
j=LNB alarm
Command or Query.
Defines how RTS/CTS will operate at the main data interface
p, No Action
looped, so that CTS echoes the state of RTS, but RTS does not
control the ON/OFF state of the carrier
ontrols Tx O/P
looped, so that CTS echoes the state of RTS, and RTS controls the
ON/OFF state of the carrier (in other words, the modem will not
bring up its TX carrier until RTS is asserted.)
Assert CTS
use. RTS/CTS ignored (Query only) RTS is ignored, and CTS is
asserted unconditionally.
Example: RTS=0 (RTS/CTS Loop, No Action).
Command only.
Forces the unit to toggle the Unit Fail relay to the 'fail' state for
approx 500ms. If the unit is a 1:1 pair, and it is currently the 'On
Line' unit, this will force a switchover, so the unit will then be in
'Standby' mode. The command is always executed by the unit,
regardless of whether it is stand-alone, in a 1:1 pair, or part of a
1:N system. This command takes no arguments.
Command or Query.
Sets or queries the user-defined Circuit ID string, which is a fixed
length of 24 characters.
Valid characters include:
Space ( ) * + – , . / 0 9 and A thru Z
