Two loopbacks are provided on the SBSLITE. The transmit 8B/10B-to-receive 8B/10B loopback
allows data entering on the incoming bus to be looped back from the output of the TW8E and
TP8E to the input of the RW8D and RP8D, respectively. Only the data looped back on the active
link (working or protection) will make it back to the outgoing bus. The transmit-to-receive
loopback allows data entering on the incoming bus to be looped back from the output of the
ICASM to the input of the OCASE and then returned to the outgoing bus.
