M40e Physical Interface Cards (PICs) Description
Physical Interface Cards (PICs) physically connect the M40e Multiservice Edge Router to network media. They are housed in Flexible PIC Concentrators (FPCs); for more information about FPCs, see M40e Flexible PIC Concentrators (FPCs) Description.
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. For complete PIC specifications, see the M40e Multiservice Edge Router PIC Guide.
Some PICs, such as selected Gigabit Ethernet PICs, accept small form-factor pluggables (SFPs), which are fiber-optic transceivers that can be removed from the PIC. Various SFPs have different reach characteristics. You can mix them in a single PIC and change the combination dynamically. SFPs are hot-removable and hot-insertable, as described in M40e Field-Replaceable Units (FRUs). For SFP replacement instructions, see Replacing an SFP in an M40e PIC. For information about PICs that use SFPs, see the M40e Multiservice Edge Router PIC Guide.
The number of ports on a PIC depends on the type of PIC. You can install up to four PICs in Type 1 FPCs and one PIC in an Type 2 FPCs (for more information, see M40e Flexible PIC Concentrators (FPCs) Description). PICs installed on Type 1 FPCs andType 2 FPCs are hot-removable and hot-insertable, as described in M40e Field-Replaceable Units (FRUs). For PIC replacement instructions, see Replacing a PIC in an M40e Router.
