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.
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
Transmit Software Signaling 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 zero 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 TPOSO and TNEGO
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 22-2
