4.1 Introduction

This chapter explains how to verify that your installation is operational.

4.2 Verifying That Your Installation Is Operational

To test that your BX 3000 hardware and DPNSS service software is installed properly:

4.2.1 Using the BX 3000 Rear Bracket LEDs

On the rear bracket of a BX 3000 is a set of green and red LEDs for each trunk interface, that indicate whether the network is connected or not and whether a protocol has been successfully started for the interface. (See Figure 14 and Figure 15).

Check the LEDs for each BX 3000 board. If a red LED is on, the board is not sensing a network connection at that trunk. Possible causes:




If a green LED is on, the DPNSS protocol did not initialize properly for the trunk. Possible causes:






4.2.2	 Checking That the Service Initialized





During system startup, the DPNSS server is loaded as a Windows NT service. To verify that the BX 3000 boards have been detected and initialized, you can first check that the CT Access DPNSS Server is running, using the Windows NT Services Control Panel. 



To check that the CT Access DPNSS Server is running:


    


  1. Click on Start. Select Settings, and then select Control Panel.
    

    
The Windows NT Control Panel folder appears.
    

  2. Double-click on the Services icon:
    

    
 

The Services window appears.
    

  3. Check that:
    

      

    • "NMS DPNSS server" is listed in the window;

      

      

    • The status of this service is "started"; 

      

      

    • The "Startup" type of this service is "automatic". 

      

    


    If there is a problem, the service will not be listed in the window, or the status of the service will be "stopped", meaning something went wrong during initialization. You can find relevant details in the Windows NT Event Viewer.
    

    

    

    4.2.3	 Using the dpnsscc Demonstration Program
    

    


    To check if you can place or receive calls on a trunk, you can use the DPNSS demonstration program dpnsscc, located in nmsdir\dpnss\Examples\dpnsscc. dpnscc presents an easy-to-use graphical user interface allowing you to create CT Access contexts, and receive incoming calls and place outgoing calls using the DPNSS service.
    


    For further information about possible configurations and how to use dpnsscc, refer to your DPNSS Service Developer's Reference Manual.
