MasterWatch User�s Manual 5-1

Chapter 5: Operator Tasks

Operator tasks are performed in the User Interface where you can view information; set alarm, surveillance, and status parameters; and test on demand.

The User Interface

Logging In1. Log into the User Interface.

� For Windows systems: Enter Windows Explorer, select the folder in which FiberWatch verson 3.1 is installed, and then double-click the file named �MasterWatch.bat�.

� For UNIX systems: Type the following command to access the FiberWatch User Interface:MasterWatch

The initial FiberWatch login window is displayed.

2. At the bottom of the FiberWatch login window, type your user name and press the tab key.3. Type your password. Notice that the characters are not displayed as you type them; asterisks are

substituted instead.4. Click OK or press the Enter key.

As you enter information into the FiberWatch windows, remember that FiberWatch is case sensitive. The system distinguishes between upper- and lower-case letters. For example, the word Robert is interpreted differently than the word robert.

Your PasswordThe system administrator assigns a temporary password when you are defined as a user of the FiberWatch system.

To change this password:

1. Follow the four steps outlined in �Logging In�, above.2. Select the User Information tab.3. Click the Change Password button. The Change Password dialog appears4. Enter the new password in both the Password and the Confirm Password fields.

NotePasswords must have at least three characters and cannot exceed 12 characters.

5. Click OK. The Change Password dialog closes.6. Select the desired tab, or click the Logout button, to continue.

Accessing FeaturesAccess to features in any interface is based on the user level assigned by the system administrator. When you enter your login password, the abilities allowed the user with that password are checked by the server and the interface is altered accordingly. Abilities for each level are listed in �Before You Begin � User Accounts� on page 6-1.

This chapter explains the features of the User Interface. Basic usage such as using the mouse, navigating the interface, and using the map tools are defined in Chapter 4, �Understanding the Basics�.

or

Click Enable to begin surveillance.

Job StatusOne of the main functions of FiberWatch is the configuration and tracking of job requests. All current test on demand and surveillance jobs for fiber circuits are shown on the Job Status tab.

The status of a job is reflected through two attributes; the current status and pending status. The current status reflects the known status of the job. The pending status reflects that status that the system is attempting to obtain for the job. See �Assessing Job Status� on page 6-68 for an explanation of the status.

Both administrators and operators can view jobs for their domains and alter the status of the job.

OTDR Expert ViewThe FiberWatch OTDR Expert View tab displays historical data from test on demand and auto routine jobs.

OTDR Expert View allow the display of up to ten fiber traces at a time to compare and analyze OTDR trace data. Each trace is displayed in a different color that can be overlaid or offset for viewing.

Using FiberWatch OTDR Expert View1. Select the OTDR Expert View tab.



2. In the Fiber Circuit List, select a domain and then select a fiber.3. If the Trace Selection pane (lower left section of the window) is not displayed, select Trace Selection

from the drop-down menu at the bottom of the pane.4. Click the down arrow in the Traces From drop-down menu and select a time frame for the trace data.

5. Choose the traces you want to compare from the Completed Traces list. Use the right arrow to move the selected trace(s) to the Traces To Plot list.



Traces are listed by date and time and display in different colors. Each color corresponds to a different trace date and time.

Change the trace view by selecting the Overlay or Offset options on the bottom of the pane.

6. Select the Primary Trace from the drop down menu. The Primary Trace will appear in black as a trace and on the bottom of the window.

7. Select Trace Loss from the drop-down menu at the bottom of the lower right pane, if not already selected. The Trace Loss information corresponds to the Primary Trace.
