(Instruction &
Qualifier)
Response to
Query
Tx Carrier
State
TXO=
1 byte, value
of 0 thru 9
Command or Query.
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? response.
Example: TXO=1 (Tx Carrier ON)

Power Level
Mode
(was AUPC
Enable)
AUP=
1 byte, 0, 1, 2
or 3
Command or Query.
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: AUP=1
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.
