Regenerator Site
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.
