About the CPU Switch Module

The CPU switch module provides intelligence to the Cisco ONS 15530. The CPU switch module
supports SNMP (Simple Network Management Protocol) and many MIBs (Management Information
Bases).
The Cisco ONS 15530 uses a QED RM7000 RISC processor. It runs at 78 MHz externally and at 234
MHz internally.It has a 64-bit multiplexed address and data bus with byte parity running at 78 MHz. It
has separate internal L1 instruction and data caches of 16 KB each and internal L2 combined
instruction/data cache of 256 KB.
The CPU switch modules also contains a 32 by 32 switch fabric that directs trafficfrom client cards to
trunk cards. The switch fabric supports 2.5 Gbps data signals with 2R transparency.
