[j-nsp] Configuring SDH on a SONET interface

[Richard A Steenbergen]

Ok I must be going nuts... I don't see ANY options for configuring SDH
mode under an interface, nor do I see anything in the online
documentation.

http://www.juniper.net/techpubs/software/junos/junos62/swconfig62-interfaces/html/interfaces-sonet-config.html

SONET and SDH traffic streams exhibit very few differences in behavior
that are significant to Juniper Networks SONET/SDH interfaces; in general,
this chapter uses SONET/SDH to indicate behavior that is identical for the
two standards. However, there is one important difference that requires
you to configure the interface specifically for SONET or SDH mode. That
difference is in the setting of two bits (the ss-bits) in the pointer.  
SONET equipment ignores these bits, but SDH equipment uses them to
distinguish a VC-4 payload from other types. When configured in SDH mode,
Juniper Networks SONET/SDH PICs set the ss-bits to s1s0 2 (binary 10). For
more information, see the JUNOS Internet Software System Basics
Configuration Guide.

Clearly there is a SDH mode, but I see NOTHING about how to enable it,
even under Internet Software System Basics. What am I missing here?
