<h2>Object state management</h2>

<p>When a local TRX lock/unlock command is given to the IDD
TRX, both IDD main and auxiliary TRX are locked/unlocked.</p>


<p>A TRX/BTS lock command from the BSC causes both the IDD
main and auxiliary TRX go to a locked state (the BSC only sees the IDD main
TRXs). A TRX/BTS unlock command from the BSC, causes both IDD main and auxiliary
TRX to be initialized.

<p>A BCF lock command from the BSC causes all TRX(s) go to
the locked state. A BCF unlock causes site reset.</p>
