Table 83: Type 1 Pic Mode Combinations - Juniper JUNOS 10.1 - CONFIGURATION GUIDE 1-2010 Configuration Manual

NOTE: Automatic Protection Switching (APS) is used by SONET add/drop multiplexers
(ADMs) to protect against circuit failures. If APS is configured, and you do not change
the SONET/SDH mode on both the working and protection port, APS support will
not function properly. Both the working and protection ports must have the same
mode configuration.
To view interface information, use the operational mode command
so-fpc/pic/port
Configuring SONET/SDH Interface Speed
You can configure the speed of SONET/SDH interfaces on next-generation SONET/SDH
Type 1 and Type 2 PICs with SFP. The speed you select is dependent upon whether
the PIC is in concatenated or nonconcatenated mode. In concatenated mode, the
bandwidth of the interface is in a single channel. In nonconcatenated mode, the PIC
operates in channelized (multiplexed) mode.
Table 83 on page 899 shows the mode combinations for the next-generation
SONET/SDH Type 1 PICs with SFP.

PIC Mode
2-port OC3 2xOC3 concatenated
4-port OC3 1xOC12 concatenated
1xOC12 nonconcatenated
4xOC3 concatenated

Table 84 on page 900 shows the mode combinations for the next-generation
SONET/SDH Type 2 PICs with SFP.
