DESCRIPTION
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 Figure 3-1).
0 = transmit all ones at TTIP and TRING
1 = transmit data normally
Automatic Transmit Unframed All Ones.
Automatically
transmit an unframed all ones pattern at TTIP and TRING
during a receive carrier loss (RCL) condition or a receive all
ones condition.
0 = disabled
1 = enabled
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 3-1).
0 = disabled
1 = enabled
Transmit PRBS Enable.
Transmit a 2
15
- 1 (E1) or a 2
20
- 1
(T1) PRBS at TTIP and TRING. See figure 3-3.
0 = disabled
1 = enabled
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 6 and figure 3-3 for
details.
0 = disabled
1 = enabled
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.
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. See figure 3-3.
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. See Figure 3-3.
