1.1 About CX 1000 Products

CX 1000 boards are one product in the family of AG Connect products. CX 1000 boards provide up to 24 analog interfaces to local analog phones, modems, headsets, etc. You can also configure and control ringing at the local phones. CX 1000 boards support conferencing.

Figure 1. CX 1000 Board Types



Here is a summary of CX 1000 products and their capabilities: 





 Board Model



 Features




 CX 1000-8



·	 8 analog local phone interfaces.


·	 Conferencing capabilities.


·	 Allows configuration and control of ringing at local phones.




 CX 1000-16



·	 16 analog local phone interfaces.


·	 Conferencing capabilities.


·	 Allows configuration and control of ringing at local phones.




 CX 1000-24



·	 24 analog local phone interfaces.


·	 Conferencing capabilities.


·	 Allows configuration and control of ringing at local phones.
















The CX 1000 product group supersedes the S Connect products previously released by NMS. S Connect and CX 1000 products are completely software compatible and can be mixed in a system. S Connect drivers can be installed on new CX 1000 systems, and a CX 1000 may be used to replace an S Connect in an existing system.






1.1.1	 CX 1000 Main Components





The main components of the CX 1000 board are:





Figure 2.	 CX 1000 Main Components


    

  • ISA bus connectivity

    

    
CX 1000 boards are full-size cards. They are designed to reside in single ISA bus slots.
    

  • Local phone connectivity

    

    
Each board connects to the local phones via a DB-62 high density connector on the card bracket. A custom cable is available that connects this port directly to a telephony type 50 pin connector (male RJ21X). You also use this cable to connect an external power supply to power the local phones, and to provide ringing voltage.
    

  • Conferencing

    

    
CX 1000 boards are capable of conferencing up to 16 parties in up to 5 conferences. For more information, see Section 5.7.
    

  • Telephony Bus Connectivity

    

    
CX 1000 boards provide full support of the MVIP-95 and MVIP-90 bus specification. The bus allows boards to share data and signaling information with other boards on the bus. For example, you can add DSP resources, analog station interfaces, or loop start line interfaces using other AG boards. You can also use MVIP-compatible products from other manufacturers with the AG board.
    
MVIP-95 is a subset of the H.100 bus specification. Thus CX 1000 boards are also interoperable with H.100 bus systems. To connect a CX 1000 board to the H.100 bus, you can use a special adapter available from NMS. For details, see the Getting Started with MVIP Switching manual.
    

  • Telephony bus switching

    

    
The MVIP switching for the CX 1000 is implemented with the FMIC (Flexible MVIP Integrated Circuit). The FMIC is a single chip that offers full support for the MVIP bus, providing access to all 512 timeslots on the bus.

    1.1.2	 Typical Configuration
    

    


    CX 1000 boards are used in conjunction with one or more other AG boards (ISA) or other MVIP- or H.100-compliant boards. These boards provide interfaces to the PSTN, and DSP resources. The CX 1000 board is connected to the other boards over the bus. The DSP resources are used for voice and call processing tasks such as voice recording and playback, DTMF detection and generation, and call progress analysis.

 Caution:
    

    


    (Europe) Only EC-approved boards may be connected to the CX 1000 board.
    

    

    


    


    

    

    

    

    

    

    1.2	 Compatibility With Telephony Standards
    

    


    CX 1000 boards provide full support of the MVIP-95 and MVIP-90 bus specification. As shown in Figure 4, the MVIP-95 and MVIP-90 are interoperable subsets of the H.100 bus standard.

    For more information, refer to Getting Started With MVIP Switching.
    

    

    

    1.2.1	 Interoperability with H.100
    

    


    The CX 1000 board is located in an ISA bus slot and connects directly to the MVIP-90/MVIP-95 bus. To connect to the H.100 bus, a special MVIP bus adapter is used, as shown in Figure 5:

    1.3	 Software Components
    

    


    To create a CX 1000 application, you will need the following software:
    

    

    

    1.3.1	 About CT Access
    

    


    CX 1000 applications are built using CT Access. CT Access is a complete software development environment for telephony applications. 
    


    In CT Access, telephony functions are grouped into logical services. Each service has a standard API. CT Access services include call control, DTMF generation and detection, and voice playing and recording. Also included is a Switching service to control switching on MVIP and H.100 bus-compliant devices. This service is used to make or break connections, send patterns, and to sample data.
    


    CT Access also includes components that configure and control AG boards other than CX 1000 boards, that have DSPs. Use these components if your application involves other AG boards in addition to CX 1000 boards. These components are:
    

    

    

    1.3.2	 About the AG Connect Driver
    

    


    The CT Access Switching service communicates with the CX 1000 board using the standard AG Connect 2.0 driver software, which runs on the host computer. To learn how to install the driver, see Chapter 3.
