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 BBSSR register is configured as follows:
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 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

Backplane Transmit BER Length Bits
The binary value of these bits defines the number of channels in addition to
the Start Channel allocated for the BER Transmitter. (i.e., Total Channels =
BTXBL value + 1)
Reserved
Must be set to 0 for normal operation
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.
