How To Use This TOP Section
Procedures in this TOP consist of the following:
a. Task Index (IXL) - an index listing tasks that may need to be performed in
establishing, operating, and maintaining the DDM-2000 OC-3 Multiplexer system.
Each colored tab in this manual contains a separate index (IXL-001) and it is always
first under each tab.
b. Non-Trouble-Clearing Procedure (NTP) - a director level procedure that lists normal
work items to perform other than trouble clearing.
c. Trouble Analysis Procedure (TAP) - a director level procedure that contains step-by-
step trouble-clearing instructions to locate and/or fix troubles.
d. Detailed Level Procedures (DLP) - detailed step-by-step instructions.
All procedures in each section of this TOP are in numerical order, regardless of the type of
procedure (see Table A.) Table A, which lists all the procedures used in this TOP, is
provided as a reference only. It should not be used alone in finding instructions for
performing tasks.
To find the instructions for performing acceptance, system turnup/circuit order, operation, or
trouble clearing tasks, proceed as follows:
1. Find your job in the Task Index (for example: Acceptance IXL-001) under the
appropriate colored tab and go to the referenced procedure. Or you may use the
Master Task Index (IXL-001) in this introduction.
2. Turn to the indicated director level, detail level, or trouble-clearing procedure listed
under the “GO TO” column for the task being performed.
3. Perform all the items in the director level procedure in the indicated order unless it
sends you to another director-level procedure. When you complete a director-level
procedure, you have finished the task. Where more detailed information is required,
you will be sent to a Detailed Level Procedure DLP-( ). You may also be sent to a
Detailed Level Procedure by another Detailed Level Procedure. All DLPs are in the
Detailed Level Procedures tab section of this manual.
4. IMPORTANT: Unless otherwise directed, when you complete a Detailed Level
Procedure, you MUST return to the procedure that sent you there.
5. IMPORTANT: Unless otherwise directed, if one director level procedure sends you
to another director level procedure, you should not return to the first director level
procedure after you complete the second.
6. Sometimes you will be asked to verify that things have occurred. This may take the
form of a formal statement of the expected response. At other times, the instructions
will merely state
verify that ... .
If the expected response is not observed and a specific trouble clearing reference is
not made, you should reference the trouble analysis procedures under the Trouble
Clearing tab to clear the trouble.

These instructions involve lasers, lightwave optical cable and connectors, and precautions
when handling circuit packs to prevent damage from electrostatic discharge. The
appropriate user/service manual contains admonishments in the form of
DANGERS,
WARNINGS
,and CAUTIONS that must be followed at all times.
These admonishments have the following definitions:
■ DANGER indicates the presence of a hazard that will cause death or severe
personal injury if the hazard is not avoided.
■ WARNING indicates the presence of a hazard that can cause death or severe
personal injury if the hazard is not avoided.
■ CAUTION indicates the presence of a hazard that will or can cause minor personal
injury or property damage if the hazard is not avoided. The caution is also used for
property-damage-only accidents. This includes equipment damage, loss of
software, or service interruption.
Lightwave Safety Guidelines
General Laser Information
Lightwave/lightguide systems, their associated test sets, and similar operating systems use
semiconductor laser transmitters that emit light at wavelengths between approximately 800
nanometers and 1600 nanometers. The emitted light is above the red end of the visible
spectrum, which is normally not visible to the human eye. Although radiant energy at near-
infrared wavelengths is officially designated invisible, some people can see the shorter
wavelength energy even at power levels several orders of magnitude below any that have
been shown to cause injury to the eye.
Conventional lasers can produce an intense beam of monochromatic light. The term
monochromaticity means a single wavelength output of pure color that may be visible or
invisible to the eye. A conventional laser produces a small-size beam of light, and because
the beam size is small the power density (also called irradiance) is very high. Consequently,
lasers and laser products are subject to federal and applicable state regulations as well as
international standards for their safe operation.
A conventional laser beam expands very little over distance, or is said to be very well
collimated. Thus, conventional laser irradiance remains relatively constant over distance.
The alert symbol appears throughout these products and the
appropriate user/service manual to alert the user to the presence of
important operating and maintenance (servicing) instructions for the
DDM-2000 Multiplexers.
!

363-206-285
Page 6 of 12 Issue 3, June 2001
DDM-2000 OC-3 MULTIPLEXER
However, lasers used in lightwave systems have a large beam divergence, typically 10 to
20 degrees. Here, irradiance obeys the inverse square law (doubling the distance reduces
the irradiance by a factor of 4) and rapidly decreases over distance.
Lasers and Eye Damage
Light energy emitted by laser and high-radiance LEDs in the 400-1400nm range my cause
eye damage if absorbed by the retina. When a beam of light enters the eye, the eye
magnifies and focuses the energy, magnifying the irradiance. The irradiance of energy that
reaches the retina is approximately 105or 100,000 times that at the cornea, and if
sufficiently intense, may cause a retinal burn.
The damage mechanism at the wavelengths used in telecommunications is thermal in
origin (that is, damage caused by heating). Therefore, a specific amount of energy is
required for a definite time to heat an area of retinal tissue. Damage is not instantaneous. It
occurs only when one looks at the light sufficiently long that the product of the retinal
irradiance and the viewing time exceeds the damage threshold. Light energies above 1400
nm would cause surface and skin burns and do not affect the retinal area.
Classification of Lasers
Manufacturers of lasers and laser products in the U.S. are regulated by the Food and Drug
Administration's Center for Devices and Radiological Health (FDA/CDRH) under 21 CFR
1040. These regulations require manufacturers to certify each laser or laser product as
belonging to one of four major Classes — Class I, II, IIa, IIIa, IIIb, or IV. Lasers are classified
according to the accessibly emission limits and their potential for causing injury. Lightwave
systems are generally classified as Class I, because, under normal operation conditions, all
energized laser transmitting circuit packs are terminated on optical fibers which enclose the
laser energy with fiber sheath, forming a protective housing. Also, covers are in place over
the circuit pack shelves.
Lightwave Safety Precautions
In its normal operating mode, a lightwave system is totally enclosed and presents no risk of
eye injury. It is a Class I system under the FDA/CDRH scheme.
The lightguide cables that interconnect various components of a lightwave system can
disconnect or break, and may expose people to lightwave emission. Also, certain
measures and maintenance procedures may expose the technician to emission from the
semiconductor laser during installation and servicing. Unlike more familiar laser devices,
such as solid-state and gas lasers, the emission pattern of a semiconductor laser results in
a highly divergent beam. In a divergent beam, the irradiance (power intensity) decreases
rapidly with distance. The greater the distance, the less energy will enter the eye, and the
less potential risk for eye injury.
Inadvertently viewing an unterminated fiber or damaged fiber with the unaided eye at
distances greater than 5 to 6 inches normally will not cause eye injury provided the power in
the fiber is less than a few mW at the shorter wavelengths and higher at the longer

363-206-285
Issue3,June2001 Page7of12
DDM-2000 OC-3 MULTIPLEXER
wavelengths. However, damage may occur if an optical instrument such as a microscope,
magnifying glass, or eye loupe is used to stare at the energized fiber end.
!CAUTION:
Use of controls or adjustments or performance of procedures other than those
specified herein may result in hazardous laser radiation exposure.
Safety Precautions for Enclosed Systems
Under normal operating conditions, lightwave transmission systems are completely
enclosed;nonetheless, the following precautions should be observed:
1. Because of the potential for eye damage, technicians should neither disconnect any
lightwave cable nor splice and stare into the optical connectors terminating the
cables.
2. Under no circumstances shall lightwave/lightguide operations be performed by a
technician before satisfactorily completing an approved training course.
3. Since viewing lightwave emission directly with an optical instrument such as an eye
loupe greatly increases the risk of eye damage, an appropriate label must appear in
plain view on the front of the main frame or lightguide termination/interconnection
equipment. The safety label (Figure 1) shall read as follows:
Figure 1. Safety Label on Inside of Front Shelf Cover

Page 8 of 12 Issue 3, June 2001
DDM-2000 OC-3 MULTIPLEXER
Safety Precautions for Unenclosed Systems
During service, maintenance, or restoration, a lightwave transmission system is considered
unenclosed. Under these conditions, follow these practices:
1. Only authorized, trained personnel shall be permitted to do service, maintenance,
and restoration. Avoid exposing the eye to emissions from unterminated, energized
optical connectors at close distances. Connectors associated with lightwave
regenerators are recessed, which limits exposure distance. However, technicians
removing or replacing regenerators should not stare or look directly into the vacant
regenerator slot with optical instruments or magnifying lenses. (Normal eyewear or
indirect viewing instruments such as a FIND-R-SCOPE*are not considered
magnifying lenses or optical instruments.)
2. Only authorized, trained personnel shall use the lightwave test equipment during
installation or servicing since this equipment contains semiconductor lasers. (Some
examples of lightguide test equipment are OTDR's, Hand-Held Loss Test Sets, and
Feature Finders.)
3. Under no circumstances shall any personnel scan a fiber with an optical test set
without verifying that all lightwave sources on the fiber are turned off.
4. All unauthorized personnel shall be excluded from the immediate area of lightwave
transmission systems during installation and service.
Consult ANSI Z136.1 American National Standard for Safe Use of Lasers for guidance on
the safe use of lasers in the workplace.

Electrostatic Discharge (ESD)
Considerations
!CAUTION:
Industry experience has shown that all integrated circuit packs can be damaged by
static electricity that builds up on work surfaces and personnel. The static charges are
produced by various charging effects of movement and contact with other objects.
Dry air allows greater static charges to accumulate. Higher potentials are measured
in areas with low relative humidity, but potentials high enough to cause damage can
occur anywhere.
The following precautions should be observed when handling circuit packs in order to
prevent damage by electrostatic discharge:
■Assume all circuit packs contain solid state electronic components that can be
damaged by ESD. Use only Lucent Technologies manufactured UL recognized
circuit packs specified in the appropriate user/service manual in this system.
■When handling circuit packs (storing, inserting, removing, etc.) or when working on
the backplane, always wear a grounded wrist strap or wear a heel strap and stand on
a grounded, static-dissipating floor mat. If a static-dissipating floor mat is used, be
sure that it is clean.
■Handle all circuit packs by the faceplate or latch and by the top and bottom
outermost edges. Never touch the components, conductors, or connector pins.
■Observe warning labels on bags and cartons. Whenever possible, do not remove
circuit packs from antistatic packaging until ready to insert them into slots.
■If possible, open all circuit packs at a static-safe work position, using properly
grounded wrist straps and static-dissipating table mats. If a static-dissipating table
mat is used, be sure that it is clean.
■Always store and transport circuit packs in static-safe packaging. Shielding is not
required unless specified.
■Keep all static-generating materials such as food wrappers, plastics, and styrofoam
containers away from all circuit packs. Upon removal from the bay, immediately put
circuit packs into static-safe packages.
■Whenever possible, maintain relative humidity above 20 percent.
To reduce the possibility of ESD damage, shelves are equipped with grounding jacks to
enable personnel to ground themselves using wrist straps (see Figure 2) while handling
circuit packs or working on a shelf(s). The jacks for connection of wrist straps are located at
the lower right-hand corner of each shelf and are labeled. When grounding jacks are not
provided, an alligator clip adapter enables connection to bay frame ground.
