path ds3 bert

Description: 

Enables bit error rate tests using the specified pattern for a DS3 signal. This command applies to a DS3 over channelized SONET interface. The no version stops the test that is running.

Syntax: 

path pathChannel ds3 ds3Channel bert pattern pattern interval time

no path pathChannel ds3 ds3Channel bert

• pathChannel—Number, in the range 1–2147483648, that identifies the path
• ds3Channel—Number, in the range 1–3, that identifies the DS3 channel
• 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 long
• 2^11—Pseudorandom test pattern, 2047 bits long
• 2^15—Pseudorandom test pattern, 32,767 bits long
• 2^20—Pseudorandom test pattern, 1,048,575 bits long
• 2^20-QRSS—Pseudorandom QRSS test pattern, 1,048,575 bits long
• 2^23—Pseudorandom test pattern, 8,388,607 bits long
• alt-0-1—Repetitive alternating test pattern of zeros and ones, 01010101...
