Layer 2,3, & 4 test patterns
PRBS:
2^31 -1 (147 483 647-bit pattern used for special measurement tasks, e.g., delay measurements at
higher bit rates)
2^23 -1 (8 388 607-bit pattern primarily intended for error and jitter measurements at bit rates of 34 368
and 139 264kbit/s)
2^15 -1 (32 767-bit pattern primarily intended for error and jitter measurements at bit rates of 1544,
2048, 6312, 8448, 32 064 and 44 736kbit/s)
2^11 -1 (2047-bit pattern primarily intended for error and jitter measurements on circuits operating at bit
rates of 64kbit/s and N x 64kbit/s)
Fixed:
All 0s or All 1s
User Defined pattern:
Length depends on frame size
Inversion:
Normal or inverted
