In JUNOS Release 8.4 and later, the family of next-generation SONET Phase I PICs includes Type 2 and Type 1 PICs. Each PIC type has three varieties.
Type1 PICs include:
Type 2 PICs include:
The support both type 1 and type 2 FPC interfaces. Hot-pluggable SFPs are used as optical transponders. The PICs provide unprecedented flexibility by allowing the user to configure a variety of modes on them through the configuration of concatenation/nonconcatenation and speed.
The 4-port OC48 PIC with SFP installed, the next-generation SONET/SDH PICs with SFP, and the 4-port OC192 PIC on M-series and T-series routing platforms, support SONET or SDH framing on a per-port basis. This functionality allows you to mix SONET and SDH modes on interfaces on a single PIC.
For information about configuring SONET/SDH framing, see Configuring SONET/SDH Framing.
For information about configuring port speed for concatenate mode on a next-generation PIC, see the JUNOS Hardware Network Operations Guide.
