(Instruction &
Qualifier)
Response to Query
Tx Carrier
State
TXO= 1 byte, 0 thru 9 Command or Query.
Sets or returns Tx Carrier State in the form x, where:
0=OFF due to front panel or remote control command
1=ON
2=RTI (receive/transmit inhibit), timeout=10 seconds
3=OFF due to ext H/W Tx Carrier- Off control *
4=OFF due to BUC or High-Stability Ref warm-up *
5=Carrier controlled by STDMA Controller *
6=RTI (receive/transmit inhibit), timeout=1 second
7=RTI (receive/transmit inhibit), timeout=2 seconds
8=RTI (receive/transmit inhibit), timeout=4 seconds
9=RTI (receive/transmit inhibit), timeout=7 seconds
NOTE: Arguments indicated with a * are status-only. They are not valid as a command, and are not indicated in MGC?

Power Level
Mode
(was AUPC
Enable)
AUP= 1 byte, 0 thru 3 Command or Query.
Sets or returns Power Level Mode in the form x, where:
0=MANUAL mode (AUPC disabled) – Normal power mode
1=AUPC enabled.
2=MANUAL-LOW – Low power mode (-65 to -20dBm) - external attenuator activated.
3=AUPC-LOW – AUPC enabled and external attenuator activated
EXAMPLE: <0/AUP=1 (AUPC Enabled)
NOTES:
1) EDMAC or D&I++, E1 D&I w/ccs or ESC++ framing must be selected for the AUPC feature to be available.
2) External 20dB Attenuator is a hardware option.

AUPC
Parameters
APP= 6 bytes Command or Query.
Sets or returns AUPC operating parameters in the form abc.cd, where:
a=Action on max. power condition: (0=do nothing, 1=generate Tx alarm)
b=Action on remote demod unlock: (0=go to nominal power, 1=go to max power)
c.c=Target Eb/No value, in dB, for remote demod from 0.0 thru 14.9:
Numbers above 9.9 use hex representation for the first character, i.e. 14.9 is coded as E.9.
d =Max increase in Tx Power permitted, in dB, from 0.0 thru 9.0
EXAMPLE: <0/APP=015.67 (Sets no alarm, max power, 5.6 dB Target and 7 dB power increase.)
