Phase Detector Up Signal Invert. When 1, the phase
detector up signal required for an external PLL in DS3
mode, is inverted from its current phase.
Phase Detector Down Signal Invert. When 1, the
phase detector down signal required for an external
PLL in DS3 mode, is inverted from its current phase.
Transmit DS3 BPV/Data In. When 1, DS3NEGDATAIN
(K22) input pin is used as external B3ZS bipolar viola-
tion indication instead of negative input pulse.
Transmit DS3 Bipolar/Unipolar. When 1, the DS3
input is bipolar; when 0, the DS3 input is unipolar.
Receive DS3 Bipolar/Unipolar. When 1, the DS3 out-
put is bipolar; when 0, the DS3 output is unipolar.
Reserved.
Transmit Serial Sync Position. Selects one of
90 positions aligned with 90 SONET columns within
SONET row 9 for the bit sync of the serial transmit data
stream (previously known as the NSMI interface data).
