• BERT — Bit-Error Rate Testing (BERT) is used for analyzing quality and for problem resolution of
digital transmission equipment.
Configuring SDH T3/E3 Parameters Configuration
To configure SDH T3/E3 parameters configuration:
enable
configure terminal
controller sdh 0/5/0
rate stm4
au-4 1
mode tug 3
tug-3 1
mode e3
e3 clock source [line | internal | recovered]
e3 framing [g751 | g832 ] (applicable to mode e3)
e3 loopback [local | network line ]
e3 bert pattern 0s interval 2
tug-3 2
mode t3
t3 1 clock source [line | internal | recovered]
t3 framing [m13 | c-bit ] (applicable to for mode t3)
t3 1 loopback [local | network line]
t3 bert pattern 0s interval 2
end
This is applicable to AUG mappaing AU-4 mode T3/E3 and AU-3 mode T3/E3.Note
Verifying SDH T3/E3 Parameters Configurations
Use show running-configuration command to verify SDH T3/E3 parameters configurations:
#show running-configuration

tug-3 1
mode E3
threshold b3-tca 0
overhead c2 0
e3 clock source internal
e3 framing g751
!tug-3 2mode T3
threshold b3-tca 0
