Extra Traffic for Restoration and Revenue
Generation 2
The FT-2000 OC-48 Add/Drop-Rings Terminal allows access to the idle protection
STS-3 tributaries for low priority traffic or for restoration purposes.
Figure 2-14 shows how the FT-2000 OC-48 Add/Drop-Rings Terminal can be
used with a DACS III-2000 and/or DACS IV-2000 Cross-Connect System and the
DACScan
â
-2000 ontroller for restoration purposes. If a failure occurs between
central offices, the
DACScan
â
-2000 controller receives alarms and sends
cross-connect commands to the DACS III-2000 and/or DACS IV-2000
Cross-Connect Systems in the network to reroute traffic around the failure. At the
FT-2000 OC-48 Add/Drop-Rings Terminals, the idle protection STS-3 tributaries
carry rerouted traffic until the failure is fixed and the regular service route is
restored.
