Code Condition and Meaning
O Operational - Alarm Enabled: The equipment is installed,
configured, and has not failed at the near end. For a CSU or
DIU, it also indicates that alarm reporting is enabled.
For a far-end circuit element, it indicates that a T1 signal is
being received.
• If the O is green, it indicates the element is not in alarm.
• If the O is red, it indicates the element is in alarm.
N Operational - Alarm Disabled: Element is operational with
a disabled alarm reporting capability.
• If the N is green, it indicates the element is not in alarm.
• If the N is red, it indicates the element is in alarm.

is not configured.
If the incoming T1 signal is lost from a near-end CSU, the
far end displays the element as absent.

database, but the module itself:
• is missing
• has failed, or
• has a blown 5V fuse.
