Why Create DCE Submaps?
Use DCE submaps to create a new set of submaps to help you picture the organization of your AT&T Paradyne DCE devices that are managed by the AT&T DCE Manager. It is important for device monitoring to be able to see the
relationships among the sites, cabinets, carriers and cards in your network. You can create submaps based on both physical and logical relationships between the devices.
Create DCE submaps based on: H Device function (such as all CSUs)
H Geographic location (such as all devices located at one site) H Network layout (such as devices connected physically or logically)
H Corporate organization (such as devices belonging to System Administrators)
Methods of Creating Submaps
HP OpenView creates hierarchical submaps during its layout operation based on the devices’ network addresses. The AT&T DCE Manager for HP OpenView for Windows product gives you the capability of adding to these submaps in two different ways:
H Connectivity submaps
The HP OpenView submap default does not show the physical connectivity of the devices in the network. However, HP OpenView does provide a feature that allows you to create connectivity submaps. Once you create DCE connectivity submaps, the AT&T DCE Manager enables you to find these
H DCE SITES submaps
The HP OpenView submap default does not show the geographical hierarchy of the devices in the network. The AT&T DCE Manager enables you to create submaps based on geographical hierarchy by using the User Sites
application.
NOTES:
It is recommended that you use the User Sites application to tell the AT&T DCE Manager where to place 3100 Series cards into a 3000 Series Carrier. This information that you enter via User Sites is used by the Device View application to accurately display the carrier view.
Only use the User Sites application to modify the DCE SITES submaps that you have created. If you make changes to these submaps using any other means, your changes may be lost the next time you use the User Sites application.
Creating HP OpenView Network
Submaps Using Autodiscovery
Before you create a submap, the devices must be autodiscovered by HP OpenView. During autodiscovery, the ALL NETS submap is created which contains a list of submaps, one for each network containing discovered devices. Refer to your HP OpenView manual for more information on the Autodiscovery feature.
NOTE:
Do not rename the ALL NETS submap or the User Sites application will not work correctly.
Viewing a List of Submaps
You use the AT&T DCE Manager to create, change, and view a list of DCE SITES submaps. You view submaps themselves using HP OpenView.
To view a hierarchical list of both the HP OpenView submaps and the AT&T DCE Manager submaps, use the User Sites window (see User Sites Window).
H The ALLNETS submap list consists of all discovered devices in the HP OpenView network.
H The DCE SITE submap list consists of all submaps that have been created for devices by the AT&T DCE Manager.
— If no DCE SITES submaps currently exist, the Sites section of the User Sites window is blank except for the DCE Sites site name.
— DCE SITES will always be the name of the first hierarchical site. See Creating and Changing the DCE Submap List if no submaps currently
User Sites Window
The User Sites window allows you to create submaps by placing device and site icons in their appropriate hierarchical location in a hierarchical list of submaps. Use the User Sites window to create, change and display the DCE SITES submap list. The User Sites Window also displays the HP OpenView submap list of all discovered devices in the network.

Connecting Devices
Connect devices in your submap to show a relationship between devices using the standard HP OpenView Connectivity feature. This relationship can be physical or logical. Be sure that you connect all supported devices to another object. Connectivity is used to identify the remote device to be selected for various device tests, such as Remote Line Loopback. See Chapter 7, Fault Isolation, for more information.
To create connectivity maps for your devices using the HP OpenView commands: 1. Use the Edit –>New Submap command to create a new submap.
2. Cut/paste DCE devices into the new submap.
3. Use Edit –> Add to add connection lines. Be sure to use the Connections button , or the connection will not be recognized.
You must connect devices before they will appear in the Test application’s remote Device Selection List box. See Device Selection List in Chapter 3, User Interface Conventions, for more information.
NOTE:
Do not use connectivity on the submaps created by the DCE Manager User Sites application since these connections will be deleted the next time that you request User Sites.
Displaying DCE Submaps
To display DCE submaps, use the standard HP OpenView feature of
double-clicking on compound icons in submaps. Displaying DCE SITES submaps allows you to monitor DCE devices based on geographical view. For example, when a device is in alert, all of its parent site, cabinet, and/or carrier objects will show the most severe alarm color. See Chapter 6, Monitoring Devices, for more information.

Diagnostic Tools
The AT&T DCE Manager provides the following tools for isolating problems with devices and their interfaces once they have been detected.
H Detailed Status – For displaying the status of the selected device and its interfaces.
H Device Identity – For displaying and modifying general information about a device and its interfaces.
H EIA Leads – For monitoring status of EIA leads on ports that support the RS232-like interface MIB (RFC 1317, RS-232-Like).
H Device Test – For performing various types of tests on the selected device’s interface(s).
Typical Fault Isolation Process
The following is an example of how you could use the AT&T DCE Manager fault isolation applications to aid you in solving problems with your devices.
1. You detect a problem with one of the DCE devices in your network. One way of detecting a problem is to view submaps to see if any device icons appear in an alarm color. Using the HP OpenView Alarm Log feature available through the AT&T DCE Manager Device View application is another way of detecting problems with a device (see Viewing a Device and Its Interfaces in Chapter 6, Monitoring Devices).
2. Use the AT&T DCE Manager Status application to view detailed status information about the selected device and its interfaces. Refer to Viewing Detailed Status in Chapter 6, Monitoring Devices, for more information.
4. Use the AT&T DCE Manager EIA Leads application to monitor the status of EIA leads on ports of the device that support the RS232 interface, if appropriate.
5. Use the AT&T DCE Manager Test application to run one or more tests on the selected device. Use the status information that you learned from the Status window to help you decide what test(s) to run.
Monitoring EIA Leads
Use the EIA Leads application to view the status of the EIA leads on the ports of the selected device that support the RS232 interface.
H Green = ON (receiving signal) H Red = off
H Gray = no status
