Configuring Next Generation SONET Phase I PICs

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:

4-port OC3
2-port OC3
1-port OC12

Type 2 PICs include:

1-port OC48
4-port OC12
4-port OC3

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.
