Configuring the pm_config
The pm_config command configures DPM and ATCC mapping to Base Radio(s) on the Site
Controller.
For more information about how to use the pm_config command, see MTS Man Machine Interface
Commands Manual.
When and where to use: The pm_config command defines the relationship between RFDS
components and Base Radios. If one cavity in an ATCC measures a high Voltage Standing Wave
Radio (VSWR), it results in the dekey of the corresponding Base Radio. A broken antenna or failure on
a feeder cable indicates a bad VSWR on the DPM. It also results in the decay of Base Radios using
this DPM.
Procedure:
1 Log on to the Site Controller Application. See Logging on to the Site Controller Application
through Serial Connection on page 223.
