Configuring the BER and TCA Threshold Values
This section describes how to configure the BER and Threshold Cross Alarms (TCA) threshold values.

DETAILED STEPS
Purpose
Command or Action
Enters the global configuration mode.
configure terminal
Example:
Router# configure terminal
Step 1
Enters the controller mode of the WAN-PHY SPA installed
in slot 2 of SIP 2 in this example.
controller wanphy interface-path-id
Example:
Router(config)# controller wanphy 2/2/0
Step 2
Sets the B1-tca threshold-crossing alarm value. The default
threshold value for B1-tca is 10e-6. The valid range for
the B1-tca threshold value is 4 to 9.
wanphy threshold b1-tca bit-error-rate
Example:
Router(config-controller)# wanphy threshold b1-tca
4
Step 3
In this example, the B1-tca threshold value is set to 4.
Sets the B2-tca threshold-crossing alarm value. The default
threshold value for B2-tca is 10e-6. The valid range for
the B2-tca threshold value is 3 to 9 (10 to minus n).
wanphy threshold b2-tca <bit-error-rate>
Example:
Router(config-controller)# wanphy threshold b2-tca
5
Step 4
In this example, the B2-tca threshold value is set to 5.
Sets the SD BER threshold-crossing alarm value. The
default SD BER threshold value is 10e-6. The value range
for SD BER threshold value is 3 to 9 (10 to minus n).
wanphy threshold sd-ber <bit-error-rate>
Example:
Router(config-controller)# wanphy threshold sd-ber
8
Step 5
In this example, the SD BER threshold value is set to 8.
