NAME AND DESCRIPTION
LOTCMC
TCR1.7
Loss Of Transmit Clock Mux Control. Determines whether
the transmit side formatter should switch to the ever present
RCLK if the TCLK input should fail to transition (Figure 1-1).
0 = do not switch to RCLK if TCLK stops
1 = switch to RCLK if TCLK stops
TFPT
TCR1.6
Transmit Framing Pass Through. (See note below.)
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. (See note below.)
0 = source CRC6 bits internally
1 = CRC6 bits sampled at TSER during F-bit time
RBSE
TCR1.4
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
TCR1.3
Global Bit 7 Stuffing. (See note below.)
0 = allow the TTR registers to determine which channels
containing all 0s are to be Bit 7 stuffed
1 = force Bit 7 stuffing in all 0 byte channels regardless of how
the TTR registers are programmed
TLINK
TCR1.2
TLINK Select. (See note below.)
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. (See note below.)
0 = transmit data normally
1 = transmit an unframed all 1s 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 detailed description of how the bits in TCR1 affect the transmit side formatter of the
DS2151Q, see Figure 14-9.
