Loop Feeder
2
The DDM-2000 Multiplexers provide a full set of interfaces, topologies, operations
and upgradability to provide the flexibility and ease of operation required to meet
the dynamic requirements of the loop feeder environment.
The DDM-2000 Multiplexers are particularly suited to the evolving needs of loop
feeder applications. They offer many essential features: compact size,
environmental hardening, single-ended operations, and capacity and topology
upgrades. The DDM-2000 Multiplexers' extensive set of topologies allows the
network to be optimized for a particular route geography, service mix, and growth
forecast.
Interoffice Transport
2
The DDM-2000 Multiplexers provide the features necessary for interoffice
transport applications. Examples include long span optics, OC-12 regenerators,
easy capacity upgrades, and full DS1 and DS3 add/drop capability. Interoffice
applications include point-to-point, stand-alone SONET electrical multiplexing,
add/drop, path switched ring, and DRI.
The DDM-2000 OC-3 and OC-12 Multiplexers provide the following features for
interoffice applications:
■
DS1 transport
■
DS3 transport
■
EC-1 transport
■
OC-3c transport
■
Synchronization distribution
■
Single-ended or independent operations
■
Single-mode fiber spans up to 55 kilometers (34 miles) for OC-3, up to 51
kilometers (32 miles) for OC-12 at a wavelength of 1310 nm, and up to 100
kilometers (61 miles) for OC-12 at a wavelength of 1550 nm.
A VT1.5/STS-1 path switched OC-3 ring is a very effective self-healing network
configuration for small cross-section interoffice networks, such as outstate trunks.
Any number of nodes in a DDM-2000 interoffice network can be independently
synchronized from a BITS clock. Timing inputs can also be provided to the BITS
from a DDM-2000 OC-3 or OC-12 Multiplexer using the DS1 timing output feature.
