modem is in terminal mode & the modem attempts
to set the BUC output power by adjusting it's output
level & a attenuator in the BUC. This can be caused
by too much attenuation in the cross site cabling or
inability to control the attenuator in the BUC (such
as use of a non-Paradise BUC with no input
attenuator)
