(MSB) (LSB)
ODF TFPT TCPT RBSE GB7S TLINK TBL TYEL
SYMBOL POSITION NAME AND DESCRIPTION
ODF TCR1.7
Output Data Format.
0=bipolar data at TPOS and TNEG.
1=NRZ data at TPOS; TNEG = 0.
TFPT TCR1.6
Transmit Framing Pass Through.
0=Ft or FPS bits sourced internally.
1=Ft or FPS bits sampled at TSER during F-bit time.
TCPT TCR1.5
Transmit CRC Pass Through.
0=source CRC6 bits internally.
1=CRC6 bits sampled at TSER during F-bit time.
RBSE TCR1.4
Robbed Bit Signaling Enable.
0=no signaling is inserted in any channel.
1=signaling is inserted in all channels (the TTR registers can be
used to block insertion on a channel by channel basis).
GB7S TCR1.3
Global Bit 7 Stuffing.
0=allow the TTR registers to determine which channels
containing all zeros are to be bit 7 stuffed.
1=force bit 7 stuffing in all zero byte channels regardless of how
the TTR registers are programmed.
TLINK TCR1.2
TLINK Select.
0=source FDL or Fs bits from TFDL register.
1=source FDL or Fs bits from the TLINK pin.
TBL TCR1.1
Transmit Blue Alarm.
0=transmit data normally.
1=transmit an unframed all 1's code at TPOS and TNEG.
TYEL TCR1.0
Transmit Yellow Alarm.
0=do not transmit yellow alarm.
1=transmit yellow alarm.
