The ONS 15454 can be configured as an effective regenerator.  An added benefit of this 
configuration is that when new services are needed at the regenerator, you simply add an 
interface card to the ONS 15454 to support the services.  This does not require any new software 
or network engineering, just plug in the interface card and turn up the service.  Figure 9-33 shows 
the ONS 15454 supporting a regenerator configuration for a linear ADM network.  The ONS 
15454 can also act as a regenerator for other SONET topologies including Path Protection 
Configuration, BLSR, and virtual rings, and PPMN meshes.  Adding new interface cards and 
activating new services is non-service affecting.

Regenerators are popular for long-haul systems where signal regeneration and future access to 
traffic is required.  Another popular configuration is the extension of digitized video traffic to other 
sites to eliminate the costs of building a new headend site.  However, the most exciting 
application is the pre-positioning of SONET terminals as future service nodes.  The continuing 
reduction in SONET costs has made this a feasible deployment option.  The ONS 15454 supports 
this application since an ONS 15454 can be configured to support terminal mode, ADM, ring, hub, 
and regenerator applications.  Figure 9-34 shows the shelf layout for the ONS 15454 OC-48 
regenerator node shown in Figure 9-33.
