Three loopbacks are provided on the SBS. The outgoing-to-incoming loopback allows data
entering the SBS on the receive interface to be looped back from the output of the OCASM to the
input of the ICASE and then returned to the transmit interface. 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 protect) 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.
