Checklist for Monitoring Redundant SSBs
Purpose You monitor redundant M20 router System and Switch Boards (SSBs) to ensure that
they do the following (see Table 157 on page 715):
• Provide allocation of incoming data packets throughout shared memory on the Flexible
PIC Concentrators (FPCs)
• Transfer outgoing data cells to the FPCs for packet reassembly
• Perform route lookups using the forwarding table, and monitor system components
for failure and alarm conditions
• Monitor FPC operation and reset
