Figure 5. RCC Logical View
Each RCC facilitates 28 links:

One link with each of the 14 packet processing card slots

One link with each of the line card slots

The RCC in slot 40 supports line card slots 17-23 and 26-32 (upper-rear slots)

The RCC in slot 41 supports line card slots 33-39 and 42-48 (lower-rear slots)
Each serial link facilitates up to 5 Gbps symbol rate, equivalent to 4 Gbps of user data traffic, in each direction.
Therefore, the Redundancy Bus provides 140 Gbps symbol rate (112 Gbps user data) of throughput per RCC, 280 Gbps
symbol rate (224 Gbps user data) total for both.
OC-48 TDM Bus
The system also hosts a dual OC-48 TDM bus consisting of 128 independent TDM paths each consisting of 512 DS0
channels. This bus supports voice services on the system. Higher speed TDM traffic requirements are addressed using
the system’s data fabric.
SPIO Cross-Connect Bus
To provide redundancy between Switch Processor I/O (SPIO) cards, the system possesses a physical interconnect
between the ports on the SPIOs. This cross-connect allows management traffic or alarm outputs to be migrated from an
active SPIO experiencing a failure to the redundant SPIO.
While an SPIO should be installed directly behind its corresponding SMC, this bus allows either SMC to utilize either
SPIO.
