Card Types
The ASR 5500 supports rear cards and front cards. Rear cards are larger and perform node management, packet
processing and I/O functions (traffic sources). Front cards determine the amount of bandwidth for the switching fabric
(crossbars), and indicate the operating and alarm status of the ASR 5500. The figure below is a simplified block diagram
showing the ASR 5500 card architecture.
