OC-12 Point-to-Point (Folded Ring)
2
Simple, efficient capacity upgrades provide an additional point of flexibility for the
DDM-2000 OC-3 and OC-12 Multiplexers. Initial deployments can be sized
according to current needs and near-term forecasts, which minimize the network's
cost. As large-scale growth occurs (for example, DS1 and DS3 service
expansion), the DDM-2000 OC-3 and OC-12 Multiplexers can be rearranged to
match each application.
The upgrade from a DDM-2000 OC-3 point-to-point system to a DDM-2000
OC-12 system can be done without interrupting service. The procedure converts
the DDM-2000 OC-3 Multiplexer shelves so that they interconnect with the
DDM-2000 OC-12 Multiplexer shelf. The resulting high-capacity, point-to-point
configuration is shown in Figure 2-14. The larger bandwidth accommodates
additional DDM-2000 OC-3 Multiplexers for DS1 access.
In addition to upgrading an existing OC-3 network, the DDM-2000 OC-12
Multiplexer also provides DS3, EC-1, OC-3 or OC-3c service transport between a
remote site and a CO. It can do this in either a stand-alone (terminal) configuration
or, if desired, it could be connected directly to a DACS IV-2000 Cross-Connect
System using DS3 or EC-1 interfaces.
