4.15.2 Ports and Line Rates
– If Port 4 is used as an STM-1, Ports 2 and 3 can be used as an STM-1 or STM-4.
– If Port 7 is used as an STM-1, Ports 5, 6, and 8 can be used as an STM-1 or STM-4.
– If Port 10 is used as an STM-1, Ports 9, 11, and 12 can be used as an STM-1 or STM-4.
– Any port can be used as an STM-4 or STM-1, as long as all of the above rules are followed.
Table 4-17 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 4-16. 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.
