Port 1 must be used for OC48/STM16 SFP. Ports 1, 4, 7, and 10 support OC12/STM-16 SFPs. All ports can be used for OC3/STM1 SFPs where the port group aggregated bandwidth does not
exceed 622 Mbps.

Ports 1, 4, 7, and 10 must be used when OC48/STM16 SFPs are used. Each port group can support a combination of SFPs whose aggregated bandwidth does not exceed 2.5 Gbps.
This table shows the rules regarding port usage on the MRC-12. This table does not show ALL possible configurations.
Scenario 1: MRC-4
Maximum bandwidth of backplane for slot is STS-12; card is installed in drop slot (slots 1-4 and
14-17) with XC-VT.

Scenario 2: MRC-4
Maximum bandwidth of card is 2.5 Gbps (STS-48); card is installed in trunk slot with XC-VT or in a
drop slot or trunk slot with XC-10G or XC-VXC-10G.
