You monitor the M20 router System and Switch Board (SSB) to ensure that it provides
allocation of incoming data packets throughout shared memory on the Flexible PIC
Concentrators (FPCs), transfers outgoing data cells to the FPCs for packet reassembly,
performs route lookups using the forwarding table, monitors system components for
failure and alarm conditions, and monitors FPC operation and reset. (See
page 505)
