8.1 Introduction

The QX 2000 board uses the NCC service component of CT Access to perform call control. Therefore, a call control program for a QX 2000 board is the same as a call control program for an AG board. See Section 8.3 for some differences when migrating from AG boards to QX boards. See the Natural Call Control Service Developer's Reference Manual for details about the NCC service.

8.2 Using the NCC Service

QDIMGR is the service manager for the NCC service used with QX 2000 boards. You specify the service and service manager names when initializing CT Access, creating event queues, and opening services.

Figure 23. QDI Service Manager and the NCC Service





8.3	 Migration from AG to QX Boards 





When you want to use a program written for AG boards with QX boards, the following modifications must be done in your source code:


    


  1. Change the name of the device manager by replacing the string ADIMGR with QDIMGR in all your source code. This must be done when calling the functions ctaInitialize and ctaOpenServices.
    

    

  2. Change the name of the switching library by replacing the string AGSW with QXSW in your source code. This must be done when calling swiOpenSwitch.
    

    

  3. Load the country specific parameters file to avoid telephony issues due to different default settings for call control parameters (use the ctdaemon program or the CT Access function ctaLoadParameterFile).
    








8.4	 Other Suggestions for Using QX Boards



8.4.1	 Using ctdaemon for Tracing





You can use the CT Access utility program ctdaemon to display traces on a QX application. You only have to load ctdaemon with the configuration file located in the country directory (e.g., ctdaemon -f c:\nms\qx\ctry\usa\q4lpsusa.par).



For more details, refer to Appendix F.






8.4.2	 Automatically Repeated Call Attempts





Your application must include, for certain countries, the control of calls internally generated by the equipment. Failing to implement this requirement will void the regulatory approval granted to NMS for this NMS equipment. See Appendix F for the requirements for each country.
