The FPCs on a router house the Physical Interface Cards (PICs), which connect the router to network media. The main function of an FPC is to connect the PICs installed in it to the other router components.
In this manual, all types of FPCs, (including Enhanced FPCs) are referred to simply as “FPC,” except where the differences among them are discussed.
Enhanced Plus Flexible PIC Concentrators (FPCs) are available for the M40e routing platform. An Enhanced Plus FPC has all the features of the corresponding standard (nonenhanced) FPC and provides additional SRAM memory (from 2 to 4 MB on an Enhanced Plus FPC1 and 4 to 8 MB on an Enhanced Plus FPC2) for increased scalability, more granular CoS capabilities, and enhanced VPN scaling.
Enhanced II Flexible PIC Concentrators (FPCs) are available for the M320, T320, T640, and T1600 routing platforms. An Enhanced II FPC has all the features of the corresponding standard and Enhanced FPCs and provides additional DRAM memory for QoS, tricolor marking, and scaling enhancements.
Enhanced III Flexible PIC Concentrators (FPCs) are available for the M320 routing platform. An Enhanced III FPC has all the features of the corresponding Enhanced II FPCs and provides additional QoS and scaling features. Enhanced III Flexible PIC Concentrators (FPCs) support any combination of PICs.
Enhanced Scaling Flexible PIC Concentrators (FPCs) are available for the T640 and T1600 routing platform. An Enhanced Scaling FPC has all the features of the corresponding standard and Enhanced FPCs and provides additional forwarding features and scalability improvements.
