2.1 Introduction

This chapter describes how to configure your AG Connect board, install it in your system, and connect it to the MVIP bus and to your operator work station network. Warning: AG Connect boards are shipped in protective anti-static containers. 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 ISA bus connectors.

Take care not to touch the gold fingers which plug into the ISA bus connectors.

2.2 System Requirements

Since the AG Connect board is used with additional MVIP-compatible boards, the exact system requirements depend on all the cards in the system. A typical PC should have: A grounded chassis. An available 16-bit ISA bus slot. One of the following operating systems installed: Windows NT 4.0, UnixWare 2.1.x or 7, or Solaris 2.6 or Solaris 7. An uninterruptable power supply (UPS). Although a UPS is not strictly required, it is strongly recommended for increased system reliability. Note that the UPS need not power the PC's video monitor.
In addition, you will need: An MVIP cable to connect your boards together on the MVIP bus. The cable length and number of connectors on the cable should not greatly exceed the number of boards in your system. An external "talk battery" power supply, to power the OWS phones connected to the card. For details, see Section 2.6.1. An adaptor cable to connect your AG Connect board to your operator work station phone lines, and to the power supply (if you need one). For details, see Section 2.6.

2.3 Configuring the Board's I/O Address Space

AG Connect boards each occupy 16 contiguous I/O addresses. These addresses must be unique and must not conflict with any other devices in your system.
To select a base address, find the I/O address switches on the face of the board and change their settings. Make a note of the base I/O address that you set the board to use. The driver software installation program you use later will prompt you for this address.

2.3.1 Changing the I/O Address

To change the I/O address for S Connect-x With Ringing boards: Find the I/O address selector switches on the face of the board. The switches are shown in Figure 5 below: Figure 5. Board Components (boards with ringing) Set the switches as directed in the table below: Base Address (Hex) Switch Setting Base Address (Hex) Switch Setting 0140 2140 0160 2160 0220 2220 0240 2240 0540 2540 0560 2560 0620 2620 0640 2640 Caution: Do not modify any other switches or jumpers on AG Connect boards.

2.4 Setting Up MVIP Connectivity

This section explains how to set up your hardware so that you can enable MVIP connectivity in your system.
In a single PC chassis with multiple boards on an MVIP bus, one board drives the bus and clock signals. The board that drives the bus clocks is called the bus clock master. All the timing signals are passed across the bus from the clock master.
All other boards (clock slaves) reference their clocks from the bus. See Getting Started With MVIP Switching for more information on telephony bus clocking.
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.) An AG Connect board can act as either a master or slave. For more information refer to Section 5.5.
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 6. Figure 6. Arranging MVIP Boards in your System
Make sure that your AG Connect board(s) are positioned appropriately for their clocking modes. Caution: In a PC chassis that contains H.100 boards and MVIP-90 boards, but does not contain an MC1 board, one of the H.100 boards must be configured as the clock master. In a system that contains H.100 boards, MVIP-90 boards, and an MC1 board, the MC1 board must be the clock master.
If you have many boards connected to the MVIP bus in your system, use a Teflon MVIP cable (available from NMS). You must use the Teflon cable if you have more than 12 boards connected to the MVIP bus in your system.

Caution:	In a PC chassis that contains H.100 boards and MVIP-90 boards, but does not contain an MC1 board, one of the H.100 boards must be configured as the clock master. In a system that contains H.100 boards, MVIP-90 boards, and an MC1 board, the MC1 board must be the clock master.

2.5 Installing Boards In Your System


Warning:	Potentially lethal voltages build up in ungrounded or poorly grounded PC chassis (for instance if the PC power cord has only two prongs on its plug, as is the case in Japan, the Philippines, and some other countries). In these cases, ground the PC with a separate ground wire, as discussed in Section 2.6.2. In addition, make sure all peripheral equipment (e.g. external power supplies, etc.) are grounded as described in Section 2.6.2. Required grounding of the PC is provided automatically if the power plug on your PC's power cord has three prongs. This is true in the US, much of Europe, and many other countries worldwide.

To install AG Connect boards in your system: If necessary, configure the board's I/O address as described in Section 2.3. Turn off the computer and disconnect it from the AC power source. Remove the cover and set it aside. Insert each board into an empty 16-bit ISA slot. Make sure the board you will use as clock master is positioned centrally, as described in Section 2.4. Fasten each board's end bracket to the back of the chassis. Connect the MVIP bus cable to the MVIP connectors on your boards. The board you have designated as clock master should be connected to a central connector on the cable. On the AG Connect board, make sure that pin 1 of the MVIP cable (marked with a colored strip) is on the side of the connector away from the metal end bracket. For best results, the length of the cable and the number of connectors on the cable should not greatly exceed the number of boards connected to it. Warning 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. Note: An AG board is not electrically connected to the MVIP bus unless its software configuration specifically enables it. Attaching the cable to the board does not affect its connectivity status. Replace the cover, and re-connect the computer to its AC power source.
Now connect the AG Connect board to your operator work station lines, and connect the external power supply, as described in the following sections.

Warning	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.

2.6 Connecting to Phones and to a Power Supply


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. · Lines to the operator work station phones should be as short as possible. · Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations. · Use caution when installing or modifying telephone lines. · If your site connects to private lines that leave the building, make sure that external protection is provided as described in Section 2.6.3.

On the AG Connect board's end bracket is a high density female D-subminiature jack which you can use to connect the board to the OWS phones and to an external power supply.

2.6.1 Cable Connections

S Connect-x With Ringing boards require a -24 Volt, 1 amp power supply to provide "talk battery" to power the operator work stations. They also require a 93V AC, 120mA (with a second output of -24V DC) power supply to power ring generation. We recommend the CNB power supply (P/N 5542) for 220 or 240 VAC countries.
The CNB power supply comes with an attached cable that connects the to board and to the telephone company interface.
Make sure the power supply is properly grounded, as described in Section 2.6.2. Note: The distance from the S-Connect to the telephone must not exceed 2000 feet. NMS recommends 24 or 26 AWG twisted pair cable for distances over 50 feet.
Refer to Appendix D for a list of signal and pin numbers from the AG Connect With Ringing boards to the line interfaces.

2.6.2 Grounding PC Chassis and Power Supply

To insure NMS boards operate correctly, and to prevent potential electrical shock, make sure your PC and the external power supply are properly grounded, and bonded (electrically connected) to each other.

3-Wire AC Systems: In countries that use grounded 3-prong AC power systems, make sure both the PC and the power supplies have grounded power cords (e.g. three prongs). The PC and the power supplies should be plugged into the same grounded circuit. NMS recommends that you run a separate 14 gauge bonding wire from the COMMON or +24VDC terminals on each power supply to screw attached to the PC chassis.

2-Wire AC Systems: If the wiring in your building does not have a ground-ing connection (e.g., outlets are 2-prong), you must provide a safety ground wire to the PC chassis, and connect a ground wire from the grounded PC chassis to any connected power supplies or other PCs in the same system. NMS recommends 14 gauge (approximately 1.5 mm diameter) ground wires. At each power supply, attach the ground wire to the "COMMON" or "+24VDC" terminal. The source of the safety ground for the PC(s) and external power supplie(s) (for 2-prong systems) should be at least a 14 gauge wire to a low-resistance ground point, such as a thick ground or neutral wire at the AC power panel, a metal water pipe that provides a continuous metal path to the earth, or a grounded metallic structural building member.

2.6.3 Providing Lightning Protection

Warning:

If any section of the wiring between the board and connected OWS phone lines runs outdoors or between buildings (buried or above ground), or your lines are more than 500 feet long in a non-metallic building, you must add a well-grounded lightning protection device in the circuit between the line and the NMS equipment. For lines that run between buildings, you or the Telco (PTT) must provide primary protectors at the building service entrance point. These can be carbon block, gas discharge, or solid-state protectors. If carbon block or gas discharge devices, you should add fast solid-state secondary protectors if your installation is in a lightning-prone area.

NMS recommends devices from ITW-Linx, Panamax, Lucent, and others. For details, contact NMS Developer Support.
