M40e PIC Overview
PICs physically connect the M40e Multiservice Edge Router to network media. They are
housed in Flexible PIC Concentrators (FPCs).
PICs receive incoming packets from the network and transmit outgoing packets to the
network, performing framing and line-speed signaling for their media type as required.
PICs also encapsulate outgoing packets received from the FPCs before transmitting
them. The controller ASIC on each PIC performs additional control functions specific to
the PIC media type.
The router supports various PICs, including ATM, Channelized, Gigabit Ethernet, IP Services,
and SONET/SDH interfaces.
