Figure 5: Interface Slot, PIC, and Port Locations

For an FPC in slot 1 with two OC3 SONET/SDH PICs in PIC positions 0 and 1, each
PIC with two ports uses the following names:
An OC48 SONET/SDH PIC in slot 1 and in concatenated mode appears as a single
FPC with a single PIC, which has a single port. If this interface has a single logical
unit, it has the following name:
An OC48 SONET/SDH PIC in slot 1 and in channelized mode has a number for each
channel. For example:
For an FPC in slot 1 with a Channelized OC12 PIC in PIC position 2, the DS3 channels
have the following names:
For an FPC in slot 1 with four OC12 ATM PICs (the FPC is fully populated), the four
PICs, each with a single port and a single logical unit, have the following names:
