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

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
