ARAMETERS

The Alarm Configuration screen (Figure 4- 14) allows
reviewing and setting alarm-related thresholds for the
selected element. These thresholds are the minimum accept-
able performance levels. To modify the parameters, high-
light the desired statistic, type in the new value (any number
from 0 to 900) and press ENTER. If this value is later sur-
passed, an alarm indication appears. A field set to 0 causes
the element not to alarm on that statistic.

Errored Seconds: This field shows the number of one-sec-
ond periods in which at least one error occurred. The default
is 45.

Severely Errored Seconds: This field shows the number of
one-second periods in which at least 320 CRC errors or one

OOF (out-of-frame) event occurred. The default is 5.

Loss of Signal Seconds: This field shows the number of
one-second periods in which the E1 received signal is inter-
rupted. The default is 5.

Unavailable Seconds: This field shows the number of one-
second periods in which consecutive severely errored sec-
onds cause an unavailable state. The default is 0.

Remote Alarm Seconds: This field shows the number of
seconds generated by the terminal equipment when an
improper signal is received from the facility (or upon receipt
of unframed all-1s). The default is 0.

AIS Seconds: This field shows the number of one-second
periods when all-1s are received. The default is 0.

Out of Frame Seconds: This field shows the number of
one-second periods in which a frame sync loss occurred.
The default is 5.

BPV Seconds: This field shows the number of one-second
periods in which at least one bipolar violation occurred. The
default is 0.

DTE LOS/OOF Seconds: This field shows the number of
one-second periods where the E1-DTE received signal
frame synchronization is interrupted or the amplitude drops
below a certain level. The default is 0.

Alarm Reset Timer: This field determines the number of
seconds after alarm conditions clear before indications are
removed. The default is 30.
