Introduction 2
DDM-2000 Multiplexers provide the flexibility required for operation in today's
changing telecommunications networks. With topology and capacity upgrades, a
DDM-2000 network can be installed with minimum first cost and then easily grown
to add new sites and new services. Many DDM-2000 circuit packs are common
with other Lucent Technologies 2000 Product Family products, resulting in further
savings as the network evolves.
The DDM-2000 OC-3 and OC-12 Multiplexers are also an ideal solution for private
network and customer location applications. The DDM-2000 OC-3 and OC-12
Multiplexers comply with electromagnetic compatibility (EMC) requirements per
FCC Title 47, Part 15, and safety requirements per
UL
1459 for equipment in
dedicated equipment rooms. The DDM-2000 Multiplexers also have Canadian
Standards Association (CSA) Certification Standard C22.2 No. 225-M90.
Standard access node configurations are available in Lucent's 51A, 80-type and
90-type BRT-2000 cabinets. Fiber distribution of DS1 services is supported with
the DDM-Plus extension shelf or DDM-2000 FiberReach, which allows mixing of
DS1 line repeater interfaces for embedded metallic facilities and protected quad
DS1 optical interfaces. DS0 and Integrated Services Digital Network (ISDN)
services are supported from the
SLC
â
-2000 Access System through copper and
fiber distribution.
The DDM-2000 FiberReach Multiplexer is the newest member of the DDM-2000
product family and can be used in all DDM-Plus applications where increased
capacity and integrated operations, maintenance, and provisioning features are
needed. Only representative DDM-2000 FiberReach Multiplexer applications are
included in this section. For more application information, see 363-206-300,
