STS-3c traffic path switching is performed through the external ATM-based
router).
Figure 8-10 shows an STS-3c 0x1 application. Each OC-12 node provisions the
same dropped STS-3c time slot as other nodes on the same ring. For different
applications, an OC-12 node can assign the other STS-3cs to different time slots
at different sites. With 0x1 applications the OC-12 ring passes the contents of
these STS-3c time slots between the low-speed OC-3/IS-3 lines and the OC-12
high-speed lines without terminating them or performing path protection switching.
Since the STS-3c traffic is received by the low-speed interfaces and transmitted
as two copies on the OC-12 ring (one clockwise, one counterclockwise), the ring
capacity is limited to the OC-12 line rate.
