ST[n]
Stream[n] BER Length Bits
The binary value of these bits refers to the number of consecutive channels expected
to receive the BER pattern. The maximum number of BER channels is 32, 64, 128 and
256 for the data rates of 2.048 Mbps, 4.096 Mbps, 8.192 Mbps and 16.384 Mbps
respectively. The minimum number of BER channels is 1. If these bits are set to zero,
no BER test will be performed.
BL8 - 0
Note: [n] denotes input stream from 0 - 31.
