You can view the results of a BERT test at the following times:
• After you terminate the test using the no bert command
• After the test runs completely
• Anytime during the test (in real time)
Bit Error Rate Testing for CESoPSN
Bit-Error Rate Testing (BERT) is used for analyzing quality and problem resolution of digital transmission
equipment. BERT tests the quality of an interface by directly comparing a pseudorandom or repetitive test
pattern with an identical locally generated test pattern. BERT is supported at the TDM side and pseudowire
side. BERT can be used either at NxDS0 or DS1 but not together.
BERT is supported on following controllers:
• T1NxDS0, DS1
• T3NxDS0, DS1 (channelised), clear channel DS3.
• OCXNxDS0, DS1 (channelised),DS3(channelised), clear channel DS3,STS1,STS-nc,VT-1.5,VT1.5 T1
Restrictions for BERT in CESoPSN
• The Cisco ASR 900 Series Router supports only the following BERT patterns: 2^11, 2^15, 2^20-O153,
and 2^20-QRSS.
• For the line side BERT to be configured at timeslot level, the first CEM should be configured and it
should be present at the same timeslot level where the BERT is configured.
