Each OC-3 node provisions the same STS-1/VT time slots as the other OC-3
nodes on the same ring. With 0x1 application, the host OC-3 or OC-12 ring
passes the content of the STS-1/VT time slots to the hosted OC-3 shelf(ves)
without terminating them or performing protection switching on them. Ring path
switching is not done on the DDM-2000 OC-12 ring; rather STS-1/VT level path
switching is done elsewhere in the network.
