SYMBOL

NAME AND DESCRIPTION
LOTCMC
TCR1.7
Loss Of Transmit Clock Mux Control. Determines
whether the transmit side formatter should switch to RCLK if
the TCLK input should fail to transition (see Figure 6-1 for
details).
0 = do not switch to RCLK if TCLK stops
1 = switch to RCLK if TCLK stops
TFPT
TCR1.6
Transmit F–bit Pass Through. (see note below)
0 = F bits sourced internally
1 = F bits sampled at TSER
TCPT
TCR1.5
Transmit CRC Pass Through. (see note below)
0 = source CRC6 bits internally
1 = CRC6 bits sampled at TSER during F–bit time
TSSE
TCR1.4
Software Signaling Insertion Enable. (see note below)
0 = no signaling is inserted in any channel
1 = signaling is inserted in all channels from the TS1-TS12
registers (the TTR registers can be used to block insertion on
a channel by channel basis)
GB7S
TCR1.3
Global Bit 7 Stuffing. (see note below)
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 0-byte channels regardless of
how the TTR registers are programmed
TFDLS
TCR1.2
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 TLINK pin
TBL
TCR1.1
Transmit Blue Alarm. (see note below)
0 = transmit data normally
1 = transmit an unframed all one’s code at TPOS and TNEG
TYEL
TCR1.0
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 TCR1 affect the transmit side formatter, see Figure 24-15.
