bert

Description: 

Enables bit error rate tests using the specified pattern on T3 interfaces on channelized and unchannelized T3 modules. The no version stops the test that is running.

NOTE: The BERT patterns supported can vary depending on the line module and I/O module assembly you are using.

Syntax: 

bert pattern pattern interval time [ unframed ]

no bert

• pattern—One of the following test patterns:

• 0s—Repetitive test pattern of all zeros, 00000...
• 1s—Repetitive test pattern of all ones, 11111...
• 2^9—Pseudorandom test pattern, 511 bits in length
• 2^11—Pseudorandom test pattern, 2047 bits in length
• 2^15—Pseudorandom test pattern, 32,767 bits in length
• 2^20-O153—Pseudorandom test pattern, 1,048,575 bits in length
• 2^20-QRSS—Pseudorandom QRSS test pattern, 1,048,575 bits in length
• 2^23—Pseudorandom test pattern, 8,388,607 bits in length
• alt-0-1—Repetitive alternating test pattern of zeros and ones, 01010101...

• time—Duration of the test in the range 1–1440 minutes
• unframed—(available for E1 and T1 interfaces only) if specified, the test bit pattern occupies all bits on the link, overwriting the framing bits; if not specified, the test bit pattern occupies only the payload bits
