[j-nsp] Configuring SDH on a SONET interface

[harry]

This is done under chassis; all ports on that PIC should use the same
framing:

[edit]
lab at M5# set chassis fpc 0 pic 0 framing ?
Possible completions:
  sdh                  SDH mode
  sonet                SONET mode
[edit]
lab at M5# set chassis fpc 0 pic 0 framing

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?
