UAS 7626 DIU

GDC 087R706-000-02                                                                                                                                            

Each Alarm Configuration Submenu lists all the alarms that the 7626 can report on a loop. 
Consult the description of the Monitor/Alarms screen, which begins on page 5-13, for definitions 
of the alarm conditions. 

The unit evaluates most alarm conditions simply on the basis of whether or not the condition 
exists. If the alarm condition exists, the unit displays it as ACTIVE on the Alarm Monitor 
terminal interface screen and generates an SNMP trap to report it if it isn’t masked. 

The two alarm conditions that the unit evaluates by means of a threshold value are the Major and 
Minor Bit Error Rate (BER) alarms. You can set each alarm to occur in response to an error rate 
of one error in 1,000, 10,000, 100,000, or 1,000,000 data bits. The on-screen entry fields display 
those rates as 10E-3, 10E-4, 10E-5, and 10E-6. 

Typically, you should configure the Minor BER alarm to occur at a lower error rate so it can serve 
as an early warning signal, and configure the Major BER alarm to occur at an error rate that 
seriously impacts operations. The threshold values you configure for BER alarms govern both 
SNMP reporting and terminal interface display.

Alarm Masks Configuration  Screen

The alarm configuration procedure involves the following steps: 

1.

From the Alarm Configuration Submenu screen, select the number of the loop for which
you intend to perform alarm configuration and press the Enter key. In response the selected
Alarm Configuration Submenu screen is displayed. 

You may want to begin by using the [8] All Alarms Control command to set all alarms 
Reported or all alarms Masked, depending on how you intend to set the majority of the 
alarm options. If you intend to change only selected items, go to step 4. 

2.

To use All Alarms Control, type 8 and press the Enter key. In response, highlighting ap-
