6.6. Loop Menu
The information displayed in this menu: Current Shelf Id, set-point, actual
power reading, and convergence state.
Possible Convergence States are:
Acquiring = Trying to acquire uplink and downlink.
Trim + /Trim - = Links acquired and convergence in progress (adjusting the
CT receive levels).
Converged = Link has converged to the set-point.
Idle = Link has converged to the set-point but there is no further activity with
the LCU. This state is not displayed when the LCU is in continuous mode and
only occurs in polled mode when the LCU performs a level control operation
and the link has converged at the set point, the LCU will stop the level control
operation . When the operation is halted the link becomes idle.
