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.
