Preliminary Information
13.11
13.11.1
Address 00C8h
Backplane BER Start Send Register defines the output channel and the stream in which the BER sequence is
transmitted. The BBSSR register is configured as follows:
13.11.2
Address 00C9h
Backplane Transmit BER Length Register (BTXBLR) defines how many channels in each frame the BER
sequence will be transmitted. The BTXBLR register is configured as follows:
15-9

Backplane Transmit BER Length Bits
The binary value of these bits define the number of channels in addition to the
Start Channel allocated for the BER Transmitter. (i.e. Total Channels = Start
Channel + BTXBL value)

Backplane BER Send Stream Address Bits
The binary value of these bits define the Backplane output stream to
transmit the BER data.
Backplane BER Send Channel Address Bits
The binary value of these bits define the Backplane output Start
Channel in which the BER data is transmitted.
