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 4000C boards, your system must have:

• A CompactPCI chassis with an H.110 compliant backplane and an available CompactPCI bus slot.
  Note: The AG 4000C board will only power up and function in a chassis with a telephony backplane.

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

• Cables to connect to a T1 trunk or to 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 DIP Switches

The AG 4000C DIP switches are located on the component side of the board.

All switches are factory-configured and should not be changed.

Figure 6. DIP Switches on the AG 4000C Board

2.5 Installing the Hardware

This section presents the procedures for installing the AG 4000C board in your system and connecting the board to the T1 or E1 trunks.

Caution:

The AG 4000C 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 handles. We recommend that you wear an anti-static wrist strap connected to a good earth ground whenever you handle the board.

2.5.1 Installing the AG 4000C Board

To install an AG 4000C board equipped with front or rear panel I/O in your system:

1. Turn off the computer and disconnect it from the AC power source. (This step is suggested for new configurations.)
   Note: If you are replacing a board that is currently in the system, refer to the OAM System User's Manual for any restrictions.

2. Choose a chassis slot in which to place the AG 4000C board. Remove the access panel to the chassis slot.

3. Verify that the chassis slot has the appropriate keying:

4. Strawberry red key in P4

5. Brilliant blue key in P1

6. Slot keying for TNV1 levels in both the front and rear chassis
   The keys in the backplane must have the same colors as the keys in the J1 and the J4 connectors of the AG 4000C board. Refer to Figure 7.

   WARNING:

   To protect yourself and your equipment, only qualified personnel can install keying. This personnel must be familiar with the CompactPCI Computer Telephony Specification PICMG 2.5, R1.0 document. NMS is not responsible if you install an AG 4000C board and chassis keying has not been properly installed.

   Note: The AG 4000C board has been keyed prior to shipment.
   For more information about keying, refer to Section 2.5.2, Keying Information.
   
   Figure 7. Keying

7. Slide the front or rear panel I/O AG 4000C board into the front of the chassis.

8. Seat the board into the backplane by rotating the top and bottom handles toward each other.
   Note: If you are installing an AG 4000C board designed for rear panel I/O, note the slot number.

9. Fasten the board to the chassis with the screws on the upper and lower handles.

10. If you are installing an AG 4000C board designed for front panel I/O, connect the computer to its AC power source. The installation process is complete.
    If you are installing an AG 4000C board designed for rear panel I/O, complete the remaining steps in this procedure.

11. Remove the rear access panel.

12. If not keyed, key the rear panel I/O transition board with the same TNV1 keying as the front I/O board. Refer to the table in Section 2.5.2 for the proper TNV1 key positions for the different NMS CompactPCI boards.

13. Slide the rear panel I/O transition board into the corresponding slot at the rear of the chassis.

    WARNING:

    Some older CompactPCI chassis may not have a rear I/O connector alignment feature. The rear panel I/O transition board requires this feature to allow insertion. Contact the chassis manufacturer to find out if your chassis supports this rear alignment feature. Use caution when inserting the board into the backplane mating connector.

14. Seat the rear panel I/O transition board by rotating the handles.

15. Fasten the board to the chassis with the screws on the upper and lower handles. Refer to Figure 8 for a view of how the AG 4000C board designed for rear panel I/O and the rear panel I/O transition board sit in the chassis.

16. Connect the computer to its AC power source (if you turned it off in Step 1).

2.5.2 Keying Information

Safety requirements dictate that the chassis slot in which you will install an AG 4000C board must be properly keyed. Keying is the mechanical interlocks which, if not correct, will stop a board from insertion.

WARNING:

To protect yourself and your equipment, only qualified personnel can install keying. NMS is not responsible if you install an AG 4000C board and chassis keying has not been properly installed.

Adhere to the following keying requirements as specified in the CompactPCI Computer Telephony Specification PICMG 2.5 R1.0:

• The key in J1 is brilliant blue.

• The key in J4 is strawberry red. The strawberry red connector indicates that the chassis has a telephony backplane. An AG 4000C board will not function in a chassis that does not have a telephony backplane.

• The slot keys (shown in Figure 7) are for TNV1. TNV1 keying for chambers B and C is manufacturer specific.

The top and bottom handles are keyed for safety. Refer to the CompactPCI Computer Telephony Specification PICMG 2.5 R1.0 and to the IEEE 1101.10 for specific keying information.

Chambers A, D, E, and F are defined by Backplane Wiring and Network Signaling Levels. Chambers B and C are user-specific. The keying for NMS boards is as follows:

	A	B	C	D	E	F
AG 4000C T	1	1	1	1	1	3
AG 4000C E 75 Ohm	1	1	2	1	1	3
AG 4000C E 120 Ohm	1	1	3	1	1	3

2.6 Connecting to the T1 or E1 Trunk

AG 4000C boards come with up to four RJ48C connectors. A shielded cable is also available. Figure 9 shows the connectors for the AG 4000C board equipped with front panel I/O:

Figure 9. Four Connectors on an AG 4000C Board Equipped With Front Panel I/O

Figure 10 shows the connectors on a rear panel I/O transition board used with the AG 4000C board equipped for rear panel I/O:

Figure 10. Four Connectors on a Rear Panel I/O Transition Board

Each of the RJ48C connectors has the pinouts shown in Figure 11:

Figure 11. RJ48C Pinouts

2.7 Connecting an AG 4000C T Board to the Network

The AG 4000C T boards have up to 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 12. AG 4000C 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 13. AG 4000C 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 4000C 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 4000C T board in the United States, specify this information:

2.8 Connecting an AG 4000C E Board to the Network

The AG 4000C E board has up to four CEPT E1 interfaces. For typical E1 communications, each E1 interface connects directly to an E1 trunk, as shown in Figure 14:

Figure 14. AG 4000C E Trunk Interface

2.8.1 Connecting an AG 4000C E 120 Ohm

To connect an AG 4000C E 120 Ohm board to the E1 trunk, a shielded RJ48 cable (NMS P/N 31082) and a connection box (NMS P/N 2282) are available. Failure to use a shielded cable may negate your Class B approval.

2.8.2 Connecting an AG 4000C E 75 Ohm

To connect an AG 4000C E 75 Ohm board to the E1 trunk, use an RJ48 to BNC adapter cable:

Figure 15. 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 16. Cable Adapter P/N 31065

Figure 17. 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 18. 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 4000C board in loopback mode to test your digital trunk application without actually connecting to the telephone network. Figure 19 shows the loopback configuration connecting trunk 1 and trunk 2 with cross-over cable P/N 31071 on an AG 4000C board:

Figure 19. Loopback Configuration

The cross-over cable connects transmit from one trunk to receive on another trunk by connecting the pins as shown in Figure 19.
