1.	Install the QX 2000 board into one of the computer's PCI bus slots.	This chapter.
2.	Install Natural Access with QX components.	The installation instructions in your Natural Access installation booklet. This booklet is also available on the NMS web site (www.nmss.com).
3.	Modify the CT Access configuration file to include the QX manager.	Chapter 3 of this manual.
4.	Add configuration information for each board to the OAM database.	Chapter 3 of this manual, and the OAM System User's Manual.
5.	Direct the OAM service to start the boards.	Chapter 3 of this manual, and the OAM System User's Manual.
6.	Verify that the installation is operational.	Chapter 4 of this manual.

The QX 2000 board is shipped in a protective anti-static container. Leave the board in its container until you are ready to install it. Handle the board carefully and only hold it by its edges. We recommend that you wear an anti-static wrist strap connected to a good earth ground whenever you handle the board. Take care not to touch the gold fingers which plug into the PCI bus connectors.

2.2 System Requirements

To install and use your QX 2000 board, your system must have:

• An available PCI bus slot.

• Natural Access, including the QX components, installed.

• An uninterruptable power supply (UPS). Although a UPS is not strictly required, it is strongly recommended for increased system availability. Note that the UPS need not power the PC's video monitor.

• Telephony bus cable if you are connecting to other telephony boards.

• Cables to connect to the telephone network.

2.2.1 Interrupts

For boards on the PCI bus, such as the QX 2000 board, the system chooses which interrupt is used for each PCI board. The system may choose to share one interrupt across several boards, or it may choose to allocate a single interrupt per board. The system may even choose to share interrupts between NMS PCI boards and boards from other vendors. You can use the pciscan utility to determine what interrupt(s) are chosen for your boards. To learn more about this utility, see the OAM System User's Manual.

WARNING:

The system BIOS for every computer system that supports a combination of PCI slots and ISA slots provides some mechanism for assigning interrupts to either the ISA slots or to the PCI and plug-n-play slots. It is critical that any interrupts that are assigned to the PCI slots are NOT used by any ISA cards. Failure to abide by this restriction will cause the QX 2000 board to malfunction. It is recommended that you make a complete list of all interrupts in use by ISA boards before configuring a QX 2000 board.

The OAM service will fail to initialize a PCI board if a board on the ISA bus uses the interrupt assigned to the PCI board.

2.3 Installing the QX 2000/100-4L Board

To install a QX 2000/100-4L board:

1. Determine H.100 bus termination

2. Install the board in the system

3. Connect to MVIP-90 boards using an MVIP Bus Adapter, if necessary

2.3.1 Terminating the H.100 Bus

In your system, your H.100 boards are connected to one another with an H.100 bus cable. The two boards located at either end of the H.100 bus must have bus termination enabled, as shown in Figure 5.

Figure 5. H.100 Bus Configuration

If your system contains MVIP-90 boards, one of your QX 2000 boards will be connected to the H.100 bus and the MVIP-90 bus through the MVIP Bus Adapter. The two ends of the H.100 bus must be terminated. The two ends of the MVIP-90 bus must not be terminated.

The bus termination is controlled by DIP switch block S1 (shown in Figure 6). The switch block is located on the component side of the board.

By default, all S1 switches are set to OFF (H.100 bus termination disabled). Setting the switches on S1 to ON enables H.100 bus termination. Set switch S1 to ON only for the boards that are on the ends of the H.100 bus.

Figure 6. QX 2000/100-4L Bus Termination DIP Switch Block

2.3.2 Installing the Board in Your System

To install a QX 2000/100-4L board in your system:

1. If necessary, configure the bus termination as described in Section 2.3.1.

2. Turn off the computer and disconnect it from the AC power source. Remove the cover and set it aside.

3. Arrange your QX 2000/100-4L board and other H.100 boards in adjacent PCI bus slots.
   Make sure each board's PCI bus connector is seated securely in a slot.

4. If your system contains MVIP-90 boards:

5. Arrange your MVIP-90 boards in adjacent bus slots.

6. Connect your MVIP-90 boards to the MVIP-90 bus cable.

7. Connect the MVIP Bus Adapter to the QX 2000/100-4L board and the MVIP-90 bus cable as described in Section 2.3.3.

Connect the QX 2000/100-4L to the H.100 bus cable.

If you have multiple H.100 boards, connect the H.100 bus cable to each of the H.100 boards.

Replace the cover, and connect the computer to its AC power source.

2.3.3 Connecting to the MVIP-90 Bus

If your system contains a QX 2000/100-4L board and MVIP-90 boards, you must use an MVIP Bus Adapter. The MVIP Bus Adapter connects the MVIP-90 bus to the H.100 bus as shown in Figure 7. Only one MVIP Bus Adapter is required in a system.

Figure 7. Connecting to the MVIP-90 Bus

The MVIP Bus Adapter allows boards connected to the H.100 bus to access the MVIP-90 bus, and allows MVIP-90 boards to access the first 16 streams of the H.100 bus. When connecting to the MVIP Bus Adapter, the first 16 streams of the H.100 bus must be configured to run in MVIP-90 mode (clocked at 2 MHz).

The MVIP Bus Adapter (shown in Figure 8) contains a connector to an H.100 board (such as the QX 2000/100-4L) and a connector to the MVIP-90 bus.

Figure 8. MVIP Bus Adapter

To connect the MVIP Bus Adapter, refer to Figure 9 and follow this procedure:

1. Connect the right angle connector (JP1) on the MVIP Bus Adapter to the connector (JP1) QX 2000/100-4L board.

2. Support the MVIP Bus Adapter by connecting the threaded mounting piece to the MVIP Bus Adapter and the QX 2000/100-4L board using two #4 screws.

3. If you have multiple H.100 boards, connect the H.100 bus cable to the QX 2000/100-4L board and to each of the other H.100 boards.

4. Connect the MVIP-90 bus cable to the connector on the MVIP Bus Adapter.

2.4 Installing the QX 2000/80-4L Board

To install the QX 2000/80-4L board:

1. Select the MVIP clock master in order to position your boards.

2. Install the board.

2.4.1 Selecting the MVIP Clock Master

MVIP boards are connected to one another with an MVIP bus cable. One of the boards must be the MVIP clock master, driving the bus clock by which all other boards synchronize their communications. All other boards must be clock slaves, synchronized by the clock master.

Some boards can act as the clock master, while others cannot. (To determine the capabilities of other boards, see the documentation which came with those boards.) If there is a digital network interface board in your system, it must be configured as the MVIP clock master.

The QX 2000 board can be configured as either an MVIP clock master or an MVIP clock slave. For more information, see Section 5.4.

In your system, position the clock master board as close to the center of the MVIP bus cable as possible. All other boards should be distributed around the clock master, as shown in Figure 10:

Figure 10. Arranging MVIP Boards in Your System

2.4.2 Installing the Board in Your System

To install the QX 2000 board in your system:

1. Turn off the computer and disconnect it from the AC power source. Remove the cover and set it aside.

2. Arrange your boards in adjacent PCI bus slots, in the order you determined in Section 2.4.1.
   Make sure each board's PCI bus connector is seated securely in a slot.

3. Fasten each board's end bracket to the back of the chassis.

4. Connect the MVIP bus ribbon cable to the MVIP connectors on your boards, so that each board is positioned on the cable in the location you determined.
   On each board, make sure that pin 1 of the cable (marked with a colored stripe) is on the side of the connectors away from the metal end bracket.

   Caution:

   As you insert the MVIP bus connectors, make sure that the pins are lined up properly. If the connector is not lined up with the header, you may bend or break a header pin. NEVER pull out the connectors by pulling the cable. Always use the white pull-out tabs to remove the MVIP bus connectors.

5. Replace the cover and reconnect the computer to its AC power source.

2.5 Connecting to the Telephone Network

WARNING:

Important Safety Notes for Telephony Connections · Installation of this board and associated telephone wiring is to be performed only by competent technical personnel. · Make sure the PC chassis is grounded through the AC power cord or by other means before connecting the telephone line. · Never install telephone wiring during a lightning storm. · Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations. · Use caution when installing or modifying telephone lines. · Telephone companies provide primary lightning protection for their telephone lines.

2.5.2 Connecting the Audio Interface

Two 3.5 mm stereo jacks are located on the QX 2000 board's end bracket for audio input and audio output. Any standard sound card or device with line input or output (CD-ROM, amplified loud speakers, etc.) is compatible with this interface.

2.6 Installing the Software

The QX 2000 driver and software is available as part of the Natural Access software package. This package is available on CD or on the NMS web site (www.nmss.com). To learn how to install the software, refer to the Natural Access CD installation booklet.

2.6.1 QXLOAD Environment Variable

The environment variable is set during software installation. QXLOAD is used to locate files to download to the QX boards. QXLOAD has the following syntax:

QXLOAD = load_directory;configuration_directory;country_directory

...where:

• load_directory is the load directory in which files to be downloaded to the boards should be located.

• configuration_directory is used for internal tests.

• country_directory is the directory where country configuration files should be located.

QXLOAD can be modified with the set shell command:

set QXLOAD = c:\nms\qx\load;c:\nms\qx\cfg;c:\nms\qx\ctry\usa

For the default installation directory c:\nms\qx, the default load and configuration directories for QXLOAD are c:\nms\qx\load and c:\nms\qx\cfg, and c:\nms\qx\ctry\xxx, where xxx is the default ISO country code.

The following table shows example values for QXLOAD, and the corresponding directory settings:

If you enter...	The load directory is set to...	The configuration directory is set to...	The country directory is set to...
set QXLOAD= (QXLOAD is not defined)	.\	.\	.\
set QXLOAD=c:\MyLoad;c:\MyConfig;c:\MyCountry	c:\MyLoad\	c:\MyConfig\	c:\MyCountry
