Media and Switch Fabric Interface
8.9.2.5 Framer, Single Network Processor, Co-Processor, and
Fabric Interface Chip
The network processor supports multiplexing the SPI-4.2 and CSIX-L1 protocols over its physical
interface via a protocol signal. This capability enables using a bridge chip to allow a single network
processor to support the ingress and egress paths between a framer and a fabric, provided the
aggregate system bandwidth does not exceed the capabilities of that single network processor, as
shown in
Figure 111 .
