Calibration (O.153 2%) – The test pattern derived from the 511 (O.153) pattern to yield a 2.005871%
BER used to verify BER measurements are operating correctly.
511 (O.153) – The unframed test pattern of continuously repeating 511-bit pseudo random number
sequences generated with a 9 bit shift register (PN9) based on ITU-T O.153 (formerly CCITT V.52) used
to perform BER testing for checking the modulation, encoding, and timing of the transmit signal
(NXDN™ CAI compliant).
