14.11.1
Address 00C8
Backplane BER Start Send Register defines the output channel and the stream on which the BER sequence is
transmitted. The minimum length of the BER transmitter is 1 channel. To set a desired BER length, set BTXBL8-0
bits for the desired length - 1 channel. For example, to run a BER test for 32 consecutive channels, program BTXBL
to 000011111
14.11.2
Address 00C9
Backplane Transmit BER Length Register (BTXBLR) defines how many channels of the BER sequence will be
transmitted in each frame. The minimum length of the BER receiver is 1 channel. To set a desired BER length, set
BRXBL8-0 bits for the desired length - 1 channel. For example, to receive a BER test for 32 consecutive channels,
program BRXBL to 000011111

Backplane BER Send Stream Address Bits
The binary value of these bits refers to the Backplane output stream
which carries the BER data.
Backplane BER Send Channel Address Bits
The binary value of these bits refers to the Backplane output channel at
which the BER data starts to be sent.
