Configuring SDH
Configuring BERT in Mode T3/E3
To configure BERT in Mode T3/E3 for both AUG mapping AU-3 and AU-4:
configure terminal
controller sdh 0/0/16
rate STM1
no ais-shut
alarm-report all
clock source internal
overhead s1s0 0
aug mapping au-4
au-4 1
mode tug-3
clock source internal
tug-3 1
mode t3
threshold b3-tca 0
overhead c2 0
t3 clock source internal
t3 bert pattern 2^15 internal 10 direction [line | system]
Verifying BERT Configuration in Mode T3/E3
Use show controllers command to verify BERT configuration in mode T3/E3:
show controller sdh 0/0/16 | sec BERT
BERT test result (running)Test Pattern : 2^15,
Status : Sync, Sync Detected : 0Interval : 10 minute(s),
Time Remain : 00:09:47
Bit Errors (since BERT started): 0 Mbits,
Bits Received (since BERT started): 0 Mbits
Bit Errors (since last sync): 1943 bits
Bits Received (since last sync): 1943 Kbits

Configuring BERT in Mode VC-1x
To configure BERT in mode VC-1x for both AUG mapping AU-3 and AU-4:
configure terminal
controller sdh 0/0/16
rate STM1
no ais-shut

tug-3 1
mode vc-1x
tug-2 1 payload VC11
vc 1 bert pattern 2^15 internal 10 direction [line | system]
Verifying BERT Configuration in Mode VC-1x
Use show controllers command to verify BERT configuration in mode VC-1x:
#show controller sdh 0/0/16 | sec BERT
