Table 14-5 describes the SONET alarms that can be configured on the POS module:
Setting Alarm Thresholds
Use the SONET alarm thresholds discussed in this section to evaluate network
performance. Alarm thresholds define the Bit Error Rate (BER) threshold values for
specific control bits in SONET frames. The default SONET alarm thresholds are
adequate for most POS installations. Refer to Table 14-10 for more information on
each alarm threshold.
Follow these steps to set SONET alarm thresholds:
1. To configure the BER threshold for the b1 threshold crossing alarm (TCA), use
the pos threshold b1-tca command in Interface Configuration mode as shown
below:
Table 14-5 SONET Alarm Commands
Command Description Default Value
pos threshold
b1-tca
The BER threshold for the
b1 threshold crossing
alarm (TCA)
4 (10E-4
Rate)
3 to 9 (10E-3 to 10E-9
Rate)
pos threshold
b2-tca
The BER threshold for the
b2 threshold crossing
alarm (TCA)
4 which is
10E-4 Rate.
3 to 9 (10E-3 to 10E-9
Rate)
pos threshold
b3-tca
The BER threshold for the
b3 threshold crossing
alarm (TCA)
4 which is
10E-4 Rate.

Rate)
