DDM-2000 FiberReach interworks with DDM-2000 OC-3/OC-12 and
SLC
-2000
Access System hosts via an exceptional variety of networking options, including
single-homed OC-1 path-switched ring extensions and fully survivable dual-
homing topologies. In every application, DDM-2000 FiberReach offers a thorough
set of operations features with a look and feel that matches the other acclaimed
DDM-2000 Multiplexer systems. Remote operation is via the data communications
channel (DCC), while a user panel and craft interface terminal port support local
operations needs. Complete performance-monitoring (PM) features, including
DS1 path PM, permit the service provider to verify the quality-of-service terms of
key tariffs.
DDM-2000 FiberReach will extend the service provider's investment in SONET
networks by supporting broadband capabilities such as two-way moving picture
experts group (MPEG 2) videoconferencing transport within standard
synchronous optical network (SONET) signal formats. Thus, new broadband
services can be created by pairing the bandwidth of DDM-2000 FiberReach with
the network survivability and resultant revenue-generating potential of path
protection switching and dual wire center architectures.
Three types of DDM-2000 FiberReach applications are offered:
■
Business Carrier Access
: Premium-tariffed telecommunications services
(via DS1 or T1 carrier extensions) supplied by public network providers to
business customers
■
Fiber in the Loop
: Cost-effective basic telephony, as well as emerging
video and data services
■
Private Networks
: Privately held networks that supply the internal
communication needs of large corporations, organizations, and institutions.
While DDM-2000 FiberReach applications are quite flexible and easy to use,
aspects like bandwidth, facility management, and operations subnetwork design
require some more detailed consideration.
