JUNOSe 11.0.x Physical Layer Configuration Guide
For detailed information about the modules that support SONET/SDH interfaces on
the E120 and E320 routers:

OCx/STMx/DS3-ATM Line Modules

OCx/STMx/DS3-ATM line modules pair with OC3-4 I/O modules to deliver
unchannelized OC3/STM1 ATM operation through four line interfaces.
OCx/STMx/DS3-ATM line modules pair with OC12 I/O modules to deliver
unchannelized OC12/STM4 ATM operation through one line interface.
I/O modules that support single-mode (intermediate reach or long haul) or multimode
operation through SC full duplex connectors are available. I/O modules that support
SONET Automatic Protect Switching (APS) 1+1 redundancy and SDH Multiplex
Section Protection (MSP) are also available.
Figure 5 on page 78 shows the interface stack for OCx/STMx/DS3-ATM interfaces.

NOTE: For a detailed description of interface types and specifiers, see Interface Types
and Specifiers in JUNOSe Command Reference Guide. For information about interfaces,
see Planning Your Network in JUNOSe System Basics Configuration Guide.

OCx/STMx POS Line Modules

OCx/STMx POS line modules pair with OC3-4 I/O modules to deliver unchannelized
OC3/STM1 POS operation through four line interfaces.
OCx/STMx POS line modules pair with OC12 I/O modules to deliver unchannelized
OC12/STM4 POS operation through one line interface.
