Introduction
1. OVERVIEW
1.1 This manual provides step-by-step procedures to enable the user to
perform a task. Each procedure contains important introductory information
that is essential to understanding and completing the task properly.
Procedures must be started at step 1, and steps must be performed in the order
given. Failure to do so may cause unforeseen hazardous conditions.
Writing Conventions
1.2 Boldface characters indicate commands or parameters the user must
enter or keys the user must press. Enter input parameters exactly as shown in
the examples.
Admonishments
1.3 To avoid hazardous conditions, observe the following admonishments:
DANGER Possibility of personal injury.
CAUTION Possibility of service interruption.
WARNING Possibility of equipment damage.

Document Types
1.5 The documentation contains all instructions needed to perform a task.
This manual consists of the following types of documents:
•Task Index List (IXL)
•Routine Task List (RTL)
•Trouble Analysis Procedure (TAP)
•Detailed Level Procedure (DLP)
Task Index List (IXL)
1.6 IXLs group procedures by function. Each IXL lists procedures
alphabetically by name and refers the user to the appropriate procedure
number.
Routine Task List (RTL)
1.7 The RTL is a list of preventive maintenance procedures. It
recommends a schedule (monthly, semiannual, or annual) for the performance
of each procedure.

Introduction 1-3
Trouble Analysis Procedure (TAP)
1.8 TAPs contain sequential steps required to perform trouble clearing.
Trouble clearing involves clearing and repairing malfunctions in the system.
Trouble clearing may be done to answer a customer complaint or to respond to
an office alarm, a trouble report, or an abnormal display. Steps can refer to
other procedures.
Detailed Level Procedure (DLP)
1.9 DLPs contain detailed steps and supporting information required to
complete tasks. When a DLP is referenced from another part of the manual,
perform the DLP, then return to the point where the DLP was referenced.

2. MAINTENANCE PHILOSOPHY
2.1 Maintenance of the system consists of repair and preventive
maintenance. Repair covers isolation of faults, troubleshooting to the circuit
card level, and subsequent replacement of the faulty circuit card. Circuit card
repair is not covered. Preventive maintenance covers periodic routine tasks
that are performed to ensure continued proper operation of the system.
2.2 The system incorporates both software- and firmware-based
diagnostics to continuously monitor system integrity. Also available are
diagnostics that can be manually invoked. Problems detected by diagnostics
are reported as alarm/event messages displayed at a user terminal and/or
lighted alarm indicators on the equipment. These messages and lights are the
primary trouble analysis tools for fault isolation.
2.3 The instruction “contact next level of technical support for assistance”
appears throughout this manual. The intent of this statement is to trigger
escalation of problems that are beyond the scope of this Task Oriented Practice
(TOP) to a higher level of expertise. Users who have local interim levels and/or
procedures should implement those in response to this instruction. Refer to
Introduction for customer access (HELP) contacts.
Troubleshooting
2.4 Troubleshooting procedures generally assume the following
conditions:
•An alarm indication was received through a user terminal or a lighted
alarm indicator.
•Maintenance personnel are familiar with system operation and use of
the TL1 language.
•Maintenance personnel have system administration privileges or a
system administrator is available.
•Replacement components (spares) are available and fully functional.

Introduction
1-6
2.5 The following guidelines and information should be observed during
troubleshooting:
•Trouble clearing begins with an analysis of alarm indications. The
proper TAP is referenced in the IXL.
•Clear upstream problems first. This may also clear downstream
problems.
•As a rule, no circuit card should be physically removed unless it was
logically removed by entering the appropriate TL1 command.
Exceptions to this are addressed in specific DLPs.
•To avoid unnecessary service interruption, exercise care when
removing circuit cards, performing commands, and doing other
maintenance tasks.
•Always follow electrostatic-sensitive device procedures when handling
circuit cards.
•TL1 commands can be entered directly or in Menu mode as desired.
•After circuit card replacement, alarms can take up to 120 seconds to
clear. Allow time for the alarm to clear before assuming the
replacement did not clear the trouble.
•When replacing a circuit card does not clear the trouble, remove the
replacement circuit card and return the original circuit card to service.
•When TAPs fail to clear the fault, an obscure or multiple fault is
assumed to exist.

3. SAFETY AWARENESS
Fan, Equipment Rack, and Equipment Cabinet Precautions
3.1 When installing the equipment observe the following:
DANGER Possibility of personal injury. Keep your fingers away from the rotating fan
blades. Pull the fan-tray module by the thumbscrews only and wait for the fan
blades to stop spinning before you attempt to remove the fan-tray module
completely from the chassis.
DANGER Possibility of personal injury. The Alcatel 1677 SONET Link requires at least
three people to support, align, and attach it to an equipment rack. To prevent
equipment damage or personal injury, make sure you have enough help.
DANGER Possibility of personal injury. To prevent personal injury and equipment
damage due to unbalanced loading of the equipment rack or cabinet, make
sure the equipment rack or cabinet is properly secured to the floor, ceiling,
or other rigid structure before mounting the Alcatel 1677 SONET Link in it.
For approved methods of securing the equipment rack, read the equipment-
rack installation instructions or contact the equipment-rack manufacturer.
Electrical Precautions
3.2 Take appropriate safety precautions when performing procedures on
electrical equipment. Hazardous electrical potentials are present when system
power is on.
3.3 Some procedures in this manual require working with small
conductive objects, such as screwdrivers, fuses, washers, screws, and nuts.
When working on a chassis at the top of an equipment rack, a dropped object
that falls into a lower chassis can cause physical damage and electrical short
circuits. To prevent this, place a piece of paper or other cover over the lower
chassis to catch fallen objects. Remove the paper or other cover when work is
complete.
DANGER Possibility of personal injury. Install the Alcatel 1677 SONET Link in a
restricted-access area only. Entrance to a restricted-access area is intended
for qualified or trained personnel and access to it is controlled by a locked
barrier.
