Monitor/Alarms
When you select Monitor/Alarms, the screen displays the UAS 7616 Alarm Monitor screen
shown in Figure 4-13. The screen displays ACTIVE or INACTIVE for each alarm condition to
indicate whether or not the condition currently exists. This screen displays alarms regardless of
masking performed in Alarm Configuration. Definitions of the alarm conditions appear below.
The screen updates every five seconds so that current information is always displayed. The cursor
highlight flickers from field to field on the screen during the brief time required to complete the
update.
When you are done viewing the Alarm Monitor screen, type 0 and press the Enter key to return
to the Main Menu.

Alarm Monitor Screen
For each of the three loops that the UAS 7616 DIU supports, the Alarm Monitor screen displays
a group of seven alarms:
Loss of CLK – occurs when the loop loses its Transmit Clock timing
Out of Sync (OOS) – occurs when the loop loses synchronization with its remote
No Sealing Current – reported when there is no current on the loop
Errored Seconds – an Errored Second contains at least one CRC error or Out of Frame
(OOF) event
Unavailable Seconds – an Unavailable Second is one in which the unit cannot pass data
Major BER – a Major Bit Error Rate alarm occurs when the error rate exceeds the
configured threshold limit
