2.2 Installation Summary

The following table summarizes the procedure for installing the hardware and software components:

Step	Description	For details, see...
1	Ensure that your PC system meets the system requirements.	Section 2.3 of this manual.
2	Install the AG Quad board into one of the computer's PCI bus slots.	Section 2.5 of this manual.
3	If you have any MVIP-90 boards, connect the MVIP Bus Adapter to one AG Quad board and the MVIP-90 bus connector to the MVIP Bus Adapter.	Appendix A of this manual.
4	If there are multiple H.100 boards, connect the H.100 bus to your H.100 boards.	Section 2.5 of this manual.
5	Install CT Access which also installs the AG Quad board driver and runtime software.	Section 2.2.1 of this manual.
6	Add configuration information for each board to the OAM database.	Chapter 3 of this manual and the OAM System User's Manual.
7	Direct the OAM service to start the boards.	Chapter 3 of this manual and the OAM System User's Manual.
8	Verify that the installation is operational.	Chapter 4 of this manual.

Note: If your system is powered down, you may want to install the board before you install the software. It does not matter if you install the board or the software first.

2.2.1 AG Driver Software

The following drivers are installed with CT Access for operating AG Quad boards:

Operating System	Driver Names
Windows NT	· aghw · ag · agsw · ag95sw · hs (optional)
UNIX	· aghw · agsw · ag95sw · agmx

2.3 System Requirements

To install and use AG Quad boards, your system must have:

• An available PCI bus slot.

• CT Access version 4.0 or later (including the ADI service) installed.

• An H.100 bus connector cable if you are connecting to any other H.100 boards.

• An MVIP-90 connector cable if you are connecting to MVIP-90 boards.

• An MVIP Bus Adapter if you are connecting to the MVIP-90 bus.

• Cables to connect to a T1 trunk or an E1 trunk.

An uninterruptable power supply (UPS) is recommended for increased system reliability. The UPS does not need to power the PC's video monitor except in areas prone to severe lightning storms.

2.4 Configuring the Hardware

2.4.1 Terminating the H.100 Bus

In your system, the H.100 boards are connected to one another with an H.100 bus cable. The two boards located at the end of the H.100 bus must have bus termination enabled, as shown in Figure 5. Bus termination is controlled by a DIP switch as explained in Section 2.4.2, Configuring the DIP Switches.

Figure 5. H.100 Bus Configuration

If your system contains MVIP-90 boards, one of the AG Quad boards will be connected to the H.100 bus and to the MVIP-90 bus using 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 AG Quad board does not terminate the MVIP-90 bus.

2.4.2 Configuring the DIP Switches

To enable or disable H.100 bus termination on an AG Quad board, set the DIP switches located on the back of the board.

DIP switch S1 (shown in Figure 6) controls the H.100 bus termination. By default, all S1 switches are set to OFF (H.100 bus termination disabled). Setting the S1 switches to ON enables H.100 bus termination. You should only set all S1 switches to ON for the boards that are on the ends of the H.100 bus.

Note: All the switches in the DIP switch S1 should be set to either ON or OFF. Switches S2-S5 are factory configured and should not be changed.

Figure 6. DIP Switches on the AG Quad Board

2.5 Installing the Hardware

Once you have configured the DIP switch on the board, you are ready to install the board in your system and connect the board to the trunk.

To install an AG Quad board in your system:

1. If necessary, configure the board as described in Section 2.4.

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

3. If you are placing the board into:

4. A PCI chassis, remove the PCI retainer bracket by unscrewing it from the board. The bracket is not needed for the board to properly fit into the chassis. The PCI retainer bracket is show in Figure 7.

5. An ISA chassis, leave the PCI retainer bracket attached to the board. The bracket is needed for the board to properly fit into the chassis.
   
   
   Figure 7. PCI Retainer Bracket

6. Arrange the AG Quad 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.

7. If your system contains MVIP-90 boards:

8. Arrange the MVIP-90 boards in adjacent ISA bus slots. Make sure each board's ISA bus connector is seated securely in a slot.

9. Connect the MVIP-90 boards to the MVIP-90 bus cable.

10. Connect the MVIP Bus Adapter to the AG Quad board and to the MVIP-90 bus cable as described in Appendix A.

Connect the AG Quad board 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 the AC power source.

2.6 Connecting to the T1 or E1 Trunk

AG Quad boards come with four RJ48C connectors, as shown in Figure 8. Shielded cables are also available for AG Quad boards.

Figure 8. AG Quad End Bracket

The connectors for the AG Dual T and AG Dual E boards are shown in Figure 9:

Figure 9. AG Dual T and AG Dual E End Bracket

Each of the RJ48C connectors has the pinouts shown in Figure 10:

Figure 10. RJ48C Pinouts

2.7 Connecting an AG Quad T to the Telephone Network

The AG Quad T board has four DSX-1 trunk interfaces.

WARNING:

Important Safety Notes for Telephony Connections The cables attached to this product must be isolated by a Channel Service Unit (CSU) before the cables leave the building.

For typical T1 communications, each trunk interface connects to a Channel Service Unit (CSU), that is connected to a T1 trunk line. The CSU provides a DSX-1 interface to the T1 line, and also contains circuitry that allows the Central Office (CO) to perform diagnostic tests remotely.

Figure 11. AG Quad T Trunk Interface with CSU

You can purchase or lease the CSU from the telephone company or other vendor. The CSU must be compatible with DSX-1 specifications, particularly in maintaining the pulse amplitude level between 2.3 and 4.2 volts.

Alternatively, you can connect the board directly to the T1 line, without a CSU. This setup is most common in applications where the T1 line is proprietary, and is not connected directly to the public network:

Figure 12. AG Quad T Trunk Interface (No CSU)

To avoid causing alarms at your T1 service provider's end, make sure that there is always a valid signal being sent, either by looping back at the CSU, or by connecting the CSU to a functioning AG Quad T board. The best way to provide a loopback is to unplug your cable from the CSU. The modular connector on most CSUs will loop back transmit to receive when nothing is plugged in.

2.7.1 Ordering T1 Service

When you order T1 service, the telephone company needs information about your system. For example, to order basic T1 service for the AG Quad T system in the United States, you will need to specify the following information:

2.8 Connecting an AG Quad E to the Telephone Network

The AG Quad E board has four CEPT E1 interfaces. For typical E1 communications, each E1 interface connects directly to an E1 trunk, as shown in Figure 13:

Figure 13. AG Quad E Trunk Interface

2.8.1 Connecting an AG Quad E 120 Ohm

To connect an AG Quad E 120 Ohm board to the E1 trunk, use a shielded RJ48 cable (NMS P/N 31082).

2.8.2 Connecting an AG Quad E 75 Ohm

To connect an AG Quad E 75 Ohm board to the E1 trunk, use an RJ48 to BNC adapter cable as shown in Figure 14:

Figure 14. RJ48 to BNC Adapter Cable

Different countries may require different adapter cables. There are three types of adapter cables available. The cables differ in the shielding of the BNC connectors as shown in the following diagrams:

Figure 15. Cable Adapter P/N 31065

Figure 16. Cable Adapter P/N 31066

Cable adapter P/N 31067 is the most common. The shield is connected to both transmit and receive BNC connectors:

Figure 17. Cable Adapter P/N 31067

The following table describes each of the adapter cables:

Cable	Description
P/N 31065	Shield is not connected to transmit and receive connectors.
P/N 31066	Shield is connected to transmit connector outer conductor.
P/N 31067	Shield is connected to transmit and receive outer conductors.

2.9 Loopback Configuration

You can connect the AG Quad board in loopback mode to test your digital trunk application without actually connecting to the telephone network. Figure 18 shows the loopback configuration connecting trunk 1 and trunk 2 with cross-over cable P/N 31071.

Figure 18. Loopback Configuration

The cross-over cable connects transmit from one trunk to receive on another trunk by connecting the pins as shown in Figure 18.
