DESCRIPTION
TUA1
CCR3.7
Transmit Unframed All Ones. The polarity of this bit is set such that the
device will transmit an all ones pattern on power-up or device reset. This
bit must be set to a one to allow the device to transmit data. The
transmission of this data pattern is always timed off of the JACLK (See
0 = transmit all ones at TTIP and TRING
1 = transmit data normally
ATUA1
CCR3.6
Automatic Transmit Unframed All Ones. Automatically transmit an
unframed all ones pattern at TTIP and TRING during a receive carrier loss
(RCL) condition or receive all ones condition.
0 = disabled
1 = enabled
TAOZ
CCR3.5
Transmit Alternate Ones and Zeros. Transmit a …101010… pattern at
TTIP and TRING. The transmission of this data pattern is always timed
off of TCLK (Figure 1-1).
0 = disabled
1 = enabled
TPRBSE
CCR3.4
Transmit PRBS Enable. Transmit a 215 - 1 (E1) or a 220 - 1 (T1) PRBS at
TTIP and TRING (Figure 1-3).
0 = disabled
1 = enabled
TLCE
CCR3.3
Transmit Loop Code Enable. Enables the transmit side to transmit the
loop up code in the Transmit Code Definition registers (TCD1 and
TCD2). See Section 4 and Figure 1-3 for details.
0 = disabled
1 = enabled
LIRST
CCR3.2
Line Interface Reset. Setting this bit from a zero to a one will initiate an
internal reset that resets the clock recovery state machine and re-centers
the jitter attenuator. Normally this bit is only toggled on power-up. Must
be cleared and set again for a subsequent reset.
IBPV
CCR3.1
Insert BPV. A 0 to 1 transition on this bit will cause a single BiPolar
Violation (BPV) to be inserted into the transmit data stream. Once this bit
has been toggled from a 0 to a 1, the device waits for the next occurrence
of three consecutive ones to insert the BPV. This bit must be cleared and
set again for a subsequent error to be inserted (Figure 1-3).
IBE
CCR3.0
Insert Bit Error. A 0 to 1 transition on this bit will cause a single logic
error to be inserted into the transmit data stream. This bit must be cleared
and set again for a subsequent error to be inserted (Figure 1-3).
