Note 1: X1 is transmitted first.
Note 2: The 84 info bits contain the repetitive sequence 1010…, where the first 1 in the sequence immediately follows each X, P, F, C, or M bit.
8. DIAGNOSTICS
PRBS Generator and Detector. Each LIU has built-in pseudorandom bit sequence (PRBS) generator and detector
circuitry for physical layer testing. The device generates and detects unframed 2
15 - 1 (DS3 or STS-1) or 223 - 1
PRBS, according to the ITU O.151 specification. To transmit a PRBS pattern, pull the TDSA and TDSB pins high
(hardware mode) or set configuration bits TDSA and TDSB (CPU bus mode). As Table 4-F shows, the PRBS
generator automatically generates 2
15 - 1 for DS3 and STS-1 modes and 223 - 1 for E3 mode.
The PRBS detector, which is always enabled (Table 4-G), reports its status through the PRBS output pin (hardware
and CPU bus modes) or through the PRBS and PBER status bits (CPU bus mode). When the PRBS detector is out
of synchronization, the PRBS pin is forced high. When the detector syncs to an incoming PRBS pattern, the PRBS
pin is driven low, then pulses high, synchronous with RCLK, for each bit error detected. See Figure 8-1 and Figure
8-2 for details. In CPU bus mode, the PRBS status bit is set to one when the detector is out of synchronization and
set to zero when the detector syncs to an incoming PRBS pattern. A change of state of the PRBS bit can cause an
interrupt on the
INT pin if the PRBSIE interrupt-enable bit is set to one. A pattern bit error can also cause an
interrupt if the PBERIE interrupt-enable bit is set to one. The PRBS detector also declares sync in the presence of
an incoming all-ones pattern.
