Multirate Cards

The maximum bandwidth of the MRC-12 card is determined by the cross-connect card, as shown in the following table.

The twelve ports of the MRC-12 card are divided into four groups, with each group having a master port as shown in the following table.

Following are the general port rate configuration rules:

The maximum bandwidth for each port is OC-48.

Port 1 can occupy all possible backplane bandwidth but cannot exceed OC-48.

Each port group can have a maximum of 25% backplane bandwidth, except for group 1.

Only a master port can occupy all possible bandwidth assigned to the group.

Based on the cross-connect card and slot limitations shown in Table D-47, the following rules apply for various synchronous transport signal (STS) available bandwidths:

STS-12

Port 1 is the only port that is usable as an OC-12/STM-4. If port 1 is used as an OC-12/STM-4, all other ports are disabled.

Ports 1, 4, 7, and 10 are the only ports usable as OC-3/STM-1. If any of these ports is used as an OC-3/STM-1, Ports 2, 3, 5, 6, 8, 9, 11, and 12 are disabled.

STS-48

Port 1 is the only port usable as an OC-48/STM-16. If port 1 is used as an OC-48/STM-16, all other ports are disabled.

Ports 1, 4, 7, and 10 are the only ports usable as OC-12/STM-4.

If port 4 is used as an OC-12/STM-4, Ports 2 and 3 are disabled.
