    Release Information

    Command introduced before JunosE Release 7.1.0.


    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.


    • 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...
    • time—Duration of the test, in the range 1–1440 minutes
