Shelf Configurations 3
A single DDM-2000 OC-3 shelf supports all the DDM-2000 OC-3 applications. Users configure
shelves for an application by equipping slots with the appropriate circuit packs and providing the
required external cabling and software. See 363-206-200,
DDM-2000 Multiplexer Applications,
Planning, and Ordering Guide
for cabling information. Only Lucent designated cables should be
used with the DDM-2000 OC-3 Multiplexer. Failure to use Lucent designated cables could void
the product warranty. Each shelf configuration requires a SYSCTL and OHCTL circuit pack to
provide the basic maintenance feature set, single-ended operations (SEO), data communication
channel (DCC) processing, and the TL1/X.25 interface. A synchronous timing generator (TGS)
circuit pack distributes a common clock to the transmission circuit packs and is required for all
configurations. A protection TGS circuit pack is recommended. Equipage of other slots depends
on the application.
All applications should be equipped with a heat baffle as shown in ED-8C724-10.
Table 3-2 is a list of circuit packs that are allowed mapped by release and shelf slots. See
Section 10, "Technical Specifications," for information on mixing OLIUs. See Section 7, "Circuit
Pack Descriptions," for more information on these and other circuit packs.
