Switch Fabric Based Line Card Protection
signals through the active switch fabric to two 2.5-Gbps ITU trunk cards or two 10-Gbps ITU tunable
or non tunable trunk cards, one in the east direction and one in the west, or two 10-Gbps uplink cards.
The aggregation card only receives the 2.5-Gbps signal from the active switch fabric.
Figure 2-10 shows switch fabric based protection with a single switch fabrics.
