2.1 Introduction

This chapter provides a procedure for installing an AG-8 or AG-8/80 board in your PC chassis.
To install the AG-8 or AG-8/80 hardware: Make sure your PC system meets the system requirements described in Section 2.2. Determine if your system will be using MVIP bus connectivity, and determine which board will operate as the bus clock master, as described in Section 2.5.1. Make sure the board's I/O address space does not conflict with that of any other device in the system. Change the I/O address if necessary, as described in Section 2.3. Insert the board into one of your computer's ISA slots, as described in Section 2.4.
After you complete the hardware installation, edit or create an AG configuration file and use it with agmon, the AG board loader/monitor utility, to verify your hardware installation. The AG configuration file, ag.cfg, specifies how the application addresses the board and how the board is configured. Chapter 3 provides detailed information about creating and modifying AG configuration files, and about using agmon.
Chapter 4 provides procedures for verifying your installation. When you have verified your board installation as a standalone board, you can continue as follows: Connect the board to the MVIP bus, if necessary, and modify your AG configuration file accordingly. Connect the AG board to the telephone network, or to the appropriate test equipment. Depending on the hybrid interfaces present on the board, you may need to connect an external power supply to the board. Re-initialize the AG board. Repeat the verification procedure.

2.2 System Requirements

To install and use one or more AG-8 or AG-8/80 boards, your system must have: An available ISA bus slot. CT Access version 1.0 or later (including the ADI service) installed. 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. If this board will be connected to other MVIP-compatible boards in the PC chassis, an MVIP-90 connector cable. For DID/E&M hybrids only, a -48 VDC external power supply (250 mA minimum current). A grounded chassis (with three-prong power cord).

2.3 Before Installing the Board

You may need to modify the interrupt setting or the I/O address for the AG-8 or AG-8/80 board. I/O addresses must be unique and must not conflict with other devices in your system. If there is a device conflict with the AG board's I/O address, change its default configuration before proceeding with the installation process.

2.3.1 Configuring the Interrupt

All AG boards on the ISA bus in the same PC chassis share the same interrupt. The setting in the sample AG configuration file is IRQ 7. If you wish to use a different interrupt setting, edit the AG configuration file, ag.cfg, as explained in Chapter 3.

2.3.2 Setting the I/O Address

Each AG-8 or AG-8/80 board occupies up to 6 contiguous I/O addresses. DIP switch S1 controls the AG board's base I/O address. The default factory setting for the base address is 0x02C0.

WARNING:

Each AG 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. Do not touch the gold fingers which plug into the ISA bus connectors.
To select another base address:

Find the I/O address selector DIP switches on the face of the board, as shown in Figure 3:

Figure 3. DIP Switches on an AG-8 Board

Set the switches for the base I/O address according to the following table:

Caution:	Do not modify any other switches or jumpers on AG-8 or AG-8/80 boards.

2.4 Installing the Board


WARNING:	Each AG 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. Do not touch the gold fingers which plug into the ISA bus connectors.

To install AG-8 or AG-8/80 boards in your system: 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. Fasten each board's end bracket to the back of the chassis. Note: If you plan to connect one or more AG boards to the MVIP bus, you may want to attach the MVIP bus cable to the boards, as described in Section 2.5.2, at this point in the installation procedure. An AG board is not electrically connected to the MVIP bus unless its software configuration specifically enables it in the AG configuration file. 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.

2.5 Setting Up MVIP Connectivity

This section explains how to set up your hardware so that you can enable MVIP connectivity in your system.
MVIP connectivity is enabled by a statement in the AG configuration file used by agmon to initialize the board. By default, MVIP connectivity is disabled in the sample AG configuration files, as explained in Section 3.5. When MVIP connectivity is disabled, default connections are made for AG-8 or AG-8/80 boards to route the voice and signaling data from the network interfaces to DSP resources.
You cannot dynamically reroute the channels to other boards or to other external resources unless you enable MVIP connectivity and use the CT Access Switching service to make connections in your application.

2.5.1 Setting Up MVIP Bus Clocking

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.
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 4. Figure 4. Arranging MVIP Boards In Your System
Make sure that your AG-8 or AG-8/80 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. Any system that contains H.100 boards, MVIP-90 boards, and an MC1 board must configure the MC1 board to 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. Any system that contains H.100 boards, MVIP-90 boards, and an MC1 board must configure the MC1 board to be the clock master.

2.5.2 Connecting to the MVIP Bus

To connect AG-8 or AG-8/80 boards to the MVIP bus: If necessary, configure the boards 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. Make sure the board you will use as clock master is positioned centrally, as described in Section 2.5.1. Make sure each board's end bracket is fastened 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. 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. . 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. Fasten each board's end bracket to the back of the chassis. Replace the cover, and re-connect the computer to its AC power source.

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 the Telephone Network

If your AG-8 or AG-8/80 board contains line interface hybrids and you will be using telephone network connectivity, set up the connection to the telephone network or to the equivalent test equipment.
Note: The AG-8 DSP and AG-8/80 DSP are DSP-only boards that do not have line interface hybrids and cannot be connected 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 lightening protection for their telephone lines. However, if a site connects to private lines that leave the building, make sure that external protection is provided.

2.6.1 Using Loop Start Interfaces

The AG-8 LS, AG-8/80 LS, and AG-8/80 ELS boards have five RJ-61X connectors at the end bracket, as shown in Figure 5. The fifth connector is not used in the loop start configuration. Figure 5. Loop Start Connector Pinouts

2.6.2 Setting Up DID Interfaces

AG-8 and AG-8/80 DID/E&M boards have five RJ-61X connectors at the end bracket, as shown in Figure 6. The fifth connector is used for the external power supply required by DID/E&M interfaces.
DID interfaces and E&M interfaces use the same hybrid module hardware; the line interface type is software-configured. The Linetype statement in the AG configuration file determines the line interface type, as described in Section 3.4. Refer to Section 3.7.1 for an example of an AG configuration file for a DID interface.
NMS recommends the TELLABS 8001 Power Supply (available from NMS) for DID and E&M-based applications. Caution: Make sure your PC is properly grounded, and that the external power supply is properly grounded and connected to the chassis ground of the PC. If the power supply is not grounded to the PC by 3-prong plugs on both cords, run a wire from the + terminal to the PC chassis. Make sure there is only one ground path between the power supply and the PC. An extra ground path can cause noise in the audio circuit.
To connect the external power supply to the bottom RJ-61X connector as shown in Figure 6: Connect the power supply GND terminal to TELGND, pins 5 and 7. Connect the - 48 V lead of the power supply to BAT-, pins 2 and 4. Connect the power supply to a power source. Connect the tip/ring pairs as required. Turn on the power source and verify that the power supply has been connected. If the power indicator LED on the end bracket is lit, the power supply is connected correctly. Figure 6. DID Connector Pinouts

2.6.3 Setting Up E&M Interfaces

AG-8 and AG-8/80 DID/E&M boards have five RJ-61X connectors at the end bracket, as shown in Figure 7. The fifth connector is used for an external power supply, which is required for DID/E&M interfaces.
DID interfaces and E&M interfaces use the same hybrid module hardware; the line interface type is software-configured. The Linetype statement in the AG configuration file determines the line interface type, as described in Section 3.4. Refer to Section 3.7.3 for an example of an AG configuration file for an E&M interface.
AG-8 and AG-8/80 DID/E&M boards support E&M types Ia, Ib, Va, and Vb. The following sections provide directions for connecting each type of E&M to the network and to the external power supply. E&M types Va and Vb are identical configurations, and are described in the same procedure.
Refer to Figure 7 for the pinouts of the connectors. Any off-the-shelf 8-position modular plug will work with the RJ-61X connectors. A 7-foot modular-to-spade lug cable adapter is available from NMS. Figure 7. E&M Connector Pinouts

E&M Type 1a


Caution:	Make sure your PC is properly grounded, and that the external power supply is properly grounded and connected to the chassis ground of the PC. If the power supply is not grounded to the PC by 3-prong plugs on both cords, run a wire from the + terminal to the PC chassis. Make sure there is only one ground path between the power supply and the PC. An extra ground path can cause noise in the audio circuit.

To connect the external power supply to the bottom RJ-61X connector as shown in Figure 8: Connect pins 4 and 2 (BAT1-) to the negative terminal of the external power supply. Connect pins 7 and 5 (TELGND) to the positive terminal of the external power supply. Connect pins 1 and 3 (SENSOR) to the negative terminal of the external power supply.
