Software Description

Local Craft Interface—The Maintenance Manager software is the local craft interface for the ONS 15200 system. Use it to view and configure certain types of system information.
Limited Read/Write—With Maintenance Manager you can change the values of a limited number of operations settings and thresholds.
Familiar Interface—The Maintenance Manager user interface is similar to the read-only Web-based interface.
Real-time—The Maintenance Manager provides a real-time view of the network. Changes to the system are reported immediately.

The Maintenance Manager screen is divided into two sections. The navigation area on the left side of the screen is used to view the ONS 15252 multichannel units (MCUs), ONS 15201 single-channel units (SCUs), modules installed in the network, event logs, and alarm logs. The display area on the right side of the screen shows information specific to each MCU, SCU, module, or log (Figure 2-1). To change a value, double-click an editable field.

2.2.1 Navigation

To navigate to different screens, click the folder or page icons in the navigation area. Clicking a folder expands it to display the pages and subfolders it contains. Clicking a page displays the relevant system information.

Note The network element (NE) that the Maintenance Manager is connected to determines which NE elements are visible.

2.2.2 System Folder

The System folder contains the following subfolders:

Path
MCU
SCU
Unit

The System folder also contains the system-level Active Alarms screen and the system-level Event Log screen.

Note The system-level Event Log screen is an aggregate of all Client Layer Interface Port (CLIP) module event logs. The system-level Active Alarms screen contains all CLIP module alarms plus all system-level alarms.

2.2.2.1 Path Folder

The Path folder provides a graphical view of any CLIP module circuit paths, as well as summaries of each circuit path parameter. These parameters include the NE status, data rate, active path, and optical coupling ratio.

2.2.2.2 MCU Folder

The MCU folder provides an inventory of the CLIP modules in each MCU in the system. CLIP modules located in the selected MCU are accessible in a separate subfolder. Click the MCU folder displays a graphical view of the MCU (Figure 2-2).

Note The specific MCUs available are dependent upon the NE to which the Maintenance Manager is connected.

Figure 2-2: MCU graphical view

2.2.2.3 SCU Folder

The SCU folder provides access to each of the visible SCUs in the Maintenance Manager. CLIP modules located in the selected SCU are accessible in a separate subfolder.

2.2.2.4 Unit Folder

The Unit folder provides access to the modules installed in the ONS 15200 network that are visible from the Maintenance Manager. Modules listed in the Unit folder are sorted by unit name rather than by the NE where they are installed.

2.2.3 CLIP Folders

The CLIP folders provide access to each CLIP module installed in the system. There are several ways to access the CLIP folder, but each provides the same categories of information. CLIP folders are located in the following folders:

Path
MCU
SCU
Unit

The CLIP folder is identified by the serial number of the CLIP module and the ITU channel where it is assigned.

Each CLIP folder contains the following screens:

CLIP Inventory
CLIP Summary
CLIP Status
CLIP Alarms

2.2.4 Paths Overview Screen

The Paths Overview screen provides a graphical view of all the circuits between ONS 15200 network elements (Figure 2-3). Icons represent the active path, standby path, network elements, and alarms.

Figure 2-3: Paths Overview screen

When you click on a particular path in the Paths Overview screen, the Path Summary screen appears (Figure 2-4). This screen shows the path for that particular channel and lists parameters for the CLIP modules in that path. Parameters include NE status, data rate, active path, and optical coupling ratio.

2.2.5 Clip Summary Screen

The information available on the Clip Summary screen varies depending on whether the Clip Summary screen is associated with a CLIP module that is configured as protected or unprotected.

The following information is provided by the Clip Summary screen:

Network Element Status
Data Rate
DWDM Status
Switch Mode (protected only)
Active Path
Standby Path (protected only)
Optical Coupling Ratio
Client Alarm Status

For more information regarding each parameter, see "CLIP Module Configuration."

Figure 2-5 shows the Clip Summary screen for a protected CLIP module.

2.2.6 Clip Status Screen

The information available on the Clip Status screen varies depending on whether the Clip Status screen is associated with a CLIP module that is configured as protected or unprotected.

The Clip Status screen provides the following information:

DWDM A RX Power
DWDM B RX Power (shown only on protected)
DWDM Peltier Current
DWDM Laser Temp
DWDM Laser Bias
Client RX Power
Client Laser Bias
Board Temperature
Power
CAN alarm
QPP A alarm
QPP B alarm (shown only on protected)

For more information regarding each parameter, see to "CLIP Module Configuration."

Figure 2-6 shows the Clip Status screen for a protected CLIP.

2.2.7 Clip Active Alarms Screen

The Clip Active Alarms screen provides a list of all active alarms (Figure 2-7). Alarm screens are available for each CLIP module and for the complete ONS 15200 system. For more information regarding each parameter, see "Alarms."

2.2.8 Event Log Screen

The Event Log screen provides a tabular list of system events (Figure 2-8). The following information is provided:

Time—in the format day, date, time, and year
Description—displays a description of the event

2.2.9 Inventory

The Inventory screen lists the modules installed in the NE (Figure 2-9).
