A DDM-2000 OC-12 Multiplexer meets Bellcore's Network Equipment Building
System (NEBS
*
) requirements. A DDM-2000 fan shelf is required in central office
environments above every DDM-2000 OC-12 Multiplexer. Refer to ED-8C724-10
and ED-8C727-10, "Typical Bay Arrangements" for detailed information on
placement of fans and heat baffles in typical bay arrangements.
The DDM-2000 OC-12 Multiplexer operates in uncontrolled environments at
temperatures of
−
40
°
C to +75
°
C and humidity of 5 to 95 percent (noncondensing).
Forced convection cooling (fans) is required in all applications. A DDM-2000
OC-12 Multiplexer provides alarming of the 2-type fan units used in Lucent
cabinets and alarming of the DDM-2000 fan shelf in controlled environments.

The DDM-2000 OC-12 Multiplexer has been tested and found to comply with the
limits for a Class A digital device, pursuant to Part 15 of the FCC rules. These
limits are designed to provide reasonable protection against harmful interference
when the equipment is operated in a commercial environment. This equipment
generates, uses, and can radiate radio-frequency energy, and if not installed and
used in accordance with the instruction manual, may cause harmful interference
to radio communications. Operation of this equipment in a residence is likely to
cause harmful interference in which case the user will be required to correct the
interference at the user's own expense. The DDM-2000 OC-12 Multiplexer has
been tested and fully meets all Bellcore EMC requirements of TR-NWT-001089,
Issue 1.
