SDH Hairpinning 
 
Some rules must be followed when an ONS 15454 is used in an SDH “hairpinning” application.  
SDH hairpinning applies when a cross-connected circuit is set-up between SDH configured 
optical cards on the same ONS 15454 node.  Table 3-3 shows the optical cards that can be used 
to hairpin circuits between two SDH configured optical ports on the same ONS 15454 node.

Managing Third-Party Network Equipment 
 
You can use the DCC tunneling feature of the Cisco ONS 15454 to provide the ability to 
transparently interconnect third party management channels of the connected SDH networks (see 
Figure 3-5).
