NAME AND DESCRIPTION
LOTCMC
TCR1A.7
Loss Of Transmit Clock Mux Control. Determines whether
the transmit side of Formatter A should switch to MCLK if the
TCLK input should fail to transition (see Figure 1.1 for details).
0 = do not switch to MCLK if TCLKA stops
1 = switch to MCLK if TCLKA stops
TFPT
TCR1A.6
Transmit F–Bit Pass Through. (see note below)
0 = F bits sourced internally
1 = F bits sampled at TSERA
TCPT
TCR1A.5
Transmit CRC Pass Through. (see note below)
0 = source CRC6 bits internally
1 = CRC6 bits sampled at TSERA during F–bit time
RBSE
TCR1A.4
Robbed Bit Signaling Enable. (see note below)
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
TCR1A.3
Global Bit 7 Stuffing. (see note below)
0 = allow the TTR registers to determine which channels
containing all 0’s are to be Bit 7 stuffed
1 = force Bit 7 stuffing in all zero byte channels regardless of
how the TTR registers are programmed
TFDLS
TCR1A.2
TFDL Register Select. (see note below)
0 = source FDL or Fs bits from the internal TFDL register
(legacy FDL support mode)
1 = source FDL or Fs bits from the internal HDLC/BOC
controller or the TLINKA pin
TBL
TCR1A.1
Transmit Blue Alarm. (see note below)
0 = transmit data normally
1 = transmit an unframed all 1’s code at TPOSOA and
TNEGOA
TYEL
TCR1A.0
Transmit Yellow Alarm. (see note below)
0 = do not transmit yellow alarm
1 = transmit yellow alarm
NOTE:
For a description of how the bits in TCR1A affect the transmit side formatter, see Figure 21-7.
