Insert PRBS Error - Channel_n:
A "0 to 1" transition within this bit-field configures the
PRBS Generator (within the Transmit Section of
Channel_n) to generate a single bit error within the out-
bound PRBS pattern-stream.
NOTES:
1. This bit-field is only active if the PRBS Generator
and Receiver have been enabled within the
corresponding Channel.
2. After writing the "1" into this register, the user
must execute a write operation to clear this
particular register bit to "0" in order to facilitate the
next "0 to 1" transition in this bit-field.

Transmit All OneS Pattern - Channel_n:
This READ/WRITE bit-field is used to command the Trans-
mit Section of Channel_n to generate and transmit an
unframed, All Ones pattern via the DS3, E3 or STS-1 line
signal (to the remote terminal equipment).
Whenever the user implements this configuration setting
then the Transmit Section will ignore the data that it is
accepting from the System-side equipment and overwrite
this data with the "All Ones" Pattern.
0 - Configures the Transmit Section to transmit the data
that it accepts from the System-side Interface.
1 - Configures the Transmit Section to generate and trans-
mit the Unframed, All Ones pattern.
