Stand-Alone OC-1 Ring/Hub Networks 2
In applications such as campus or other self-contained environments, DDM-2000
FiberReach can be deployed in a stand-alone OC-1 ring. This OC-1 ring
extension can be configured directly from a DDM-2000/
SLC -2000 shelf with
27-type OLIUs in the main slots. A mix of DS1 and T1 carrier traffic from remote
DDM-2000 FiberReach nodes can be flexibly groomed and dropped at the host to
a mix of DS1, EC-1, and OC-3 interfaces, as shown in Figure 2-14. Channels can
be established directly between two DDM-2000 FiberReach remotes on the same
OC-1 ring. This configuration would be very effective for customers within a short
radius of the wire center or for isolated demand at a distant location where there is
no appropriate access network yet in place.
