SLM-3650 Satellite Modem
Options
A.1.4.1
Local AUPC
The AUPC function allows each of two modems in a closed link to control the output of
the other modem. Both modems must have the AUPC options enabled. These options are:
AUPC ENABLE
NOMINAL POWER
MINIMUM POWER
MAXIMUM POWER
TARGET NOISE
TRACKING RATE
LOCAL CL ACTION
REMOTE CL ACTION
With AUPC enabled on both modems (A and B), if modem A loses carrier:
1. Modem A sets its output power (MAXIMUM, MINIMUM, OR HOLD) as
specified by LOCAL CL ACTION.
2. Modem A then sends a "lost carrier" command to modem B.
3. Modem B sets its output power (MAXIMUM, MINIMUM, OR HOLD) as
specified by REMOTE CL ACTION.
4. Once modem A has reacquired the carrier, it sends commands to modem B to
achieve the desired E
modem A to increase or decrease power to maintain modem B's target E
