4.18 4.18.2 Ports and Line Rates
– If Port 10 is used as an OC-3, Ports 9, 11, and 12 can be used as an OC-3 or OC-12.
– Any port can be used as an OC-12 or OC-3, as long as all of the above rules are followed.
Table 4-20 shows the 15454_MRC-12 port availability and line rate for each port, based on total
available bandwidth. To use the table, go to the rows for the bandwidth that you have available, as
determined in Table 4-19. Each row indicates what line rate can be provisioned for each port (identified
in the MCR-12 Port Number row). The Ports Used column shows the total number of ports that can be
used with each bandwidth scheme.
