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.
