0
Fractional/Signaling Interface Enabled
This bit is used to enable or disable the transmit fractional data interface, sig-
naling input, as well as the 32MHz transmit clock and the transmit overhead
Signal output.
0 = Configures the 5 time slot identifier pins (TxChn[4:0]) to output the channel
number as usual.
1 = Configures the 5 time slot identifier pins (TxChn[4:0]) to function as the fol-
lowing:
TxChn[0] becomes the Transmit Serial SIgnaling pin (TxSIG_n) for signaling
inputs. Signaling data can now be input from the TxSIG pin if configured
appropriately.
TxChn[1] becomes the Transmit Fractional Data Input pin (TxFrTD_n) for frac-
tional data input. Fractional data can now be input from the TxFrTD pin if con-
figured appropriately.
TxChn[2] becomes the 32 MHz transmit clock output
TxChn[3] becomes the Transmit Overhead Signal which pulses high on the
first bit of each multi-frame.
NOTE:
This bit has no effect in the high speed or multiplexed modes of
operation. In high-speed or multiplexed modes, TxCHN[0] functions
as TxSIGn for signaling input.

TxICLKINV
R/W
0
Transmit Clock Inversion (Backplane Interface)
This bit selects whether data transition will happen on the rising or falling edge
of the transmit clock.
0 = Selects data transition to happen on the rising edge of the transmit clocks.
1 = Selects data transition to happen on the falling edge of the transmit clocks.
NOTE:
This feature is only available for base rate configuration (i.e. non-
highspeed, and non-multiplexed modes).

TxMUXEN
R/W
0
Multiplexed Mode Enable
This bit enables or disables the multiplexed mode. When multiplexed mode is
enable, multiplexed data of four channels at 12.352 or 16.384MHz are demul-
tiplexed inside the transmit framer and sent to 2 channels on the line side. The
backplane speed will be running at either 12.352 or 16.384MHz depending on
the multiplexed mode selected by TxIMODE[1:0] of this register.
0 = Disables the multiplexed mode.
1 = Enables the multiplexed mode.
