OC-12 OC-3c Transport Shelf 3
Figure 3-12 shows a DDM-2000 OC-12 shelf equipped for an OC-3c transport
application. The main application of a shelf, configured in this way, is transport of
video or asynchronous transfer mode (ATM) signals. Bandwidth is mapped into
STS-3c "bundles," and the bundles follow the same path to preserve the
isochronous (known, periodic time interval) nature of the transported information.
