Sets the Reset Timer threshold. This read/write field is used to establish the
contiguous number of seconds that an alarm parameter must be clear before
the alarm is reset. Applicable values range from 000 through 900. A value of
"000" means the alarm will never be reset.
The Network screens provide the user-selectable prompts described in the
table below.
Prompt Function
Clear Alarms Resets the alarm conditions related to the Network and counts to
zero.
Learn DS0s Now Learns which DS0s are active and assigns them to the first
associated network service. Learned DS0s are based on the idle
pattern specified in the Channel Table (see below).
Performance Displays a current count of the number of error events that have
occurred over the past 24 hours and the past 30 days.
Channels Displays the Channel Table Details screen (found on page 4-16),

Performance Screens

The Performance prompt near the bottom of the Network screen displays a
Performance 24 Hour screen (Figure 4.8), which provides a summary of the
error events that have occurred during each interval of the past 24 hours. In
addition to the parameters already defined on the Error Status and Alarm
Thresholds Table on page 4-8, the following parameters are included on the
Performance 24 Hour screen.
The Bursty Error Seconds (BES) refers to a 1-second period during which at
least more than one but fewer than 320 CRC6 errors occurred.
The Loss of Frame Count (LOFC) represents the number of time a loss of
frame is declared. A loss of frame is declared after 2.5 seconds of continuous
loss of signal or OOF.
The Cyclic Redundancy Check Errored Seconds (CRCES) is a method of
confirming the integrity of received data.
