Network Channel Status Indicator Interpretation
• Steady - indicator is on continuously in the defined state.
• Alternating - the two indicators alternate between the two defined states
at the same time (applies to both indicators viewed together). The two
indicators are always in opposite states, out of phase.
• Flashing - the indicator alternates between the two defined states
(applies to each indicator viewed independent of the other). If both
indicators flash, they must flash together, in phase.
