path ds1|e1 bert

Description: 

Enables bit error rate tests using the specified pattern at the DS1/E1 over SONET/SDH VT layer on channelized SONET and SDH interfaces. The no version stops the test that is running.

Syntax: 

path pathChannel { ds1 | e1 } tributaryIdentifier bert
pattern pattern interval time [ unframed ]

no path pathChannel { ds1 | e1 } tributaryIdentifier bert

• pathChannel—Number, in the range 1–2147483648, that identifies the path
• tributaryIdentifier—Identifier for the tributary. See description for the path ds1|e1 command.
• pattern—One of the following test patterns:

• 2^11—Pseudorandom test pattern, 2,047 bits long
• 2^15—Pseudorandom test pattern, 32,767 bits long
• 2^20-O153—Pseudorandom test pattern, 1,048,575 bits long

• time—Duration of the test, in the range 1–1440 minutes
• unframed—Test bit pattern occupies all bits on the link, overwriting the framing bits. If you do not specify this keyword, the test bit pattern occupies only T1/E1 payload bits.
