Introduction to the DDM-2000 OC-12
Multiplexer
1
The DDM-2000 OC-12 Multiplexer is a single shelf SONET digital multiplexer. A
single 12-inch shelf supports a mix of digital signal 3 (DS3), electrical carrier 1
(EC-1), and optical carrier level 3 (OC-3) signals and multiplexes them into a
SONET standard 622 Mb/s optical carrier level 12 (OC-12) rate.
The OC-12 and OC-3 optical lines, all transmission-affecting circuit packs, and the
−
48 V DC power feeders may be optionally protected. The shelf can be equipped
to serve many diverse network applications and supports a variety of operations
interfaces for current and evolving network operations needs.
The DDM-2000 OC-12 Multiplexer is designed for loop (access), interoffice
(transport), and customer location applications. The DDM-2000 OC-12 Multiplexer
starts with many of the proven features of Lucent Technologies’ DDM-1000 and
DDM-2000 OC-3 Multiplexers and extends into the future with the flexibility of the
SONET standard.
The DDM-2000 OC-12 Multiplexer is designed for easy installation and operation.
Installation is simplified with integrated test capabilities and default provisioning.
Centralized operation is supported by a full set of single-ended control and
maintenance features. Built-in maintenance capabilities support both installation
and system operation. A DDM-2000 OC-12 Multiplexer can be fully tested and
installed without using external test equipment. Some tasks can be performed
using faceplate light-emitting diode (LED) displays and controls, while a craft
interface terminal (CIT) gives access to sophisticated maintenance, provisioning,
and reporting features. A personal computer (PC) is needed to download software
and to run CPro-2000 graphical user interface tool software.
The OC-12 Regenerator extends the span length of the DDM-2000 OC-12
Multiplexer and is supported in both unbalanced and balanced modes. Diverse
routing is supported in either mode, allowing one line to travel over a longer route
than the other. The OC-12 Regenerator uses the same shelf and some of the
same circuit packs as the OC-12 Multiplexer. See 363-206-207, "DDM-2000
OC-12 Multiplexer and OC-12 Regenerator User/Service Manual" for more
information on the OC-12 Regenerator.
The DDM-2000 OC-12 Multiplexer has a phased release plan. This manual has
been issued to introduce Release 7.0 and will be updated to cover additional
releases as they become available.
