The information displayed is generally useful for diagnostic tasks performed by technical support
personnel only. For the PA-E3, the show controllers serial command also displays configuration
information such as the framing, clock source, bandwidth limit, whether scrambling is enabled, the

performance statistics for the current interval and last 15-minute interval and whether any alarms
exist.
