Description |
For details, see ... |
|
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. |
Section 2.3. |
|
2 |
Insert the board into one of your computer's ISA slots. |
Section 2.6.1. |
|
3 |
Connect the MVIP bus connector, if necessary. |
Section 2.6.1. |
|
10 |
If application development is complete, connect the board to the E1 or T1 network. |
Section 2.8. |
|
Caution: |
NMS 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. |
|
Caution: |
AG-T1 and AG-E1 boards are shipped configured for various trunk configurations. These configurations are controlled by various jumpers on the boards. Do not change the jumper settings on these boards. If you do so, your product may not work. |
To install and use your AG-T1 or AG-E1 board, you need a computer with:
An AG-T1 or AG-E1 board occupies 16 contiguous I/O addresses. These addresses must be unique and must not conflict with any other devices in your system.
The default factory setting for the base address is 0x02C0. If you need to select another base address:

Figure 3: AG-T1 and AG-E1 Switches and Connectors
The default interrupt for the board is IRQ 12. To set a different interrupt, edit the AG configuration file as described in Chapter 3.
All ISA-compatible AG boards in a system share the same interrupt.
To install AG-T1 or AG-E1 boards in your system with no MVIP connectivity:
Now complete your installation as described in section 2.7.
If you plan to enable MVIP switching between multiple boards in your system, you will need to select a board that will act as the MVIP clock master, driving the bus clock by which all other boards synchronize their communications. All other boards must be configured as clock slaves.
Most MVIP-compatible boards (from NMS and from other manufacturers) can be configured to act as either clock masters or as clock slaves. In your system, the clock master should be an AG-T1 or AG-E1 board that is connected to an E1 or T1 trunk, so the clock is synchronized with the clock on the E1 or T1 line. (See Figure 4.)
Figure 4: MVIP Clock Master and Slaves
All boards on the MVIP bus will be connected to one another with an MVIP bus cable, as described in section 2.6.1. The clock master must be positioned in the center of the MVIP ribbon cable, as shown in Figure 5.
Figure 5: Arranging MVIP Boards in Your System
Note: If you have many AG boards in your system, you should use a Teflon MVIP cable (available from NMS). You must use the Teflon cable if you have over 12 boards in your system.
To direct a board to act as clock master or slave, change the ClockRef setting in your AG configuration file, as described in Chapter 3.
To install AG-T1 or AG-E1 boards in your system and connect them to the MVIP bus:
Make sure the board you have designated as clock master is positioned centrally, as shown in Figure 5.
The board you have designated as clock master should be connected to a central connector on the cable, as shown in Figure 5.
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. |
Now complete your installation as described in section 2.7.
Once you have installed your hardware as described in the sections above, do the following:
Caution: |
You must complete all required performance tests, and a type approval certificate must be granted by the appropriate regulatory authority in the target country before you can connect the AG-T1 board into the public network. |
The AG-T1 board has a DSX-1 trunk interface. For typical T1 communications, the board connects to a Channel Service Unit (CSU), which is connected to a T1 trunk line. The CSU provides a DSX-1 interface to the T1 line, and also contains circuitry which allows the Central Office (CO) to perform diagnostic tests remotely. (See Figure 6.)
Figure 6: AG-T1 Trunk Interface (With CSU)
The CSU can be purchased or leased from the telephone company or any other vendor. The CSU must be compatible with the DSX-1 specifications, particularly in maintaining the pulse amplitude level at between 2.3 and 4.2 volts. (See Appendix D.)
Alternatively, the board can connect 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. (See Figure 7.)
Figure 7: AG-T1 Trunk Interface (No CSU)
When you order T1 service, the telephone company needs to know information about your system. For example, to order basic T1 service for your AG-T1 system in the United States, you will need to specify the following information:
Product Manufacturer: Natural MicroSystems Corporation
Product Name: AG-T1
Service Type: T1, D4 or ESF format (B8ZS is also supported)
Signaling: Four wire terminated E&M (robbed-bit)
Start: Wink start
Dial Tone: Enabled (standard frequency)
Digits: DTMF (pulse dial supported but DTMF preferred)
Interface Code: 04DU9-B
Service Code: 6.0P
Channels: 24 (typically)
Ringer Equivalence: 0.0A
Outdial Senderized: Yes
FCC Registration: EMCUSA-21110-XD-N
USOC Jack Required: RJ48C or RJ48X
AG-T1 boards come with single RJ48C connectors, as shown in Figure 8.
Figure 8: AG-T1 and AG-E1 End Bracket Components
With AG-T1 boards, a twisted-pair modular cable with RJ48C connectors is supplied, (shown in Figure 9). Also available is a loopback block, which you can use to connect the board's transmit channels to its receive channels for loopback testing (see section 2.10).
Figure 9: RJ48C Network Connector (shown with ferrite block)
The RJ48C has the pinouts shown in Figure 10.

To avoid causing alarms at your T1 service provider's end, be sure that t a valid signal is continuously sent to them, either by looping the signal back at the CSU, or by connecting the CSU to a functioning AG-T1 board. The best way to provide a loopback is simply to unplug your cable from the CSU. The modular connector on most CSUs will loop back the transmit signal to the receive signal when there is nothing plugged in.
Caution: |
Natural MicroSystems obtains board-level approvals certificates for supported countries. Some countries require that you obtain system-level approvals before connecting a system to the public network. To learn what approvals you require, contact the appropriate regulatory authority in the target country. |
The AG-E1 has one CEPT E1 interface. For typical E1 communications, the board connects directly to an E1 trunk, as shown in Figure 11.
Figure 11: AG-E1 Trunk Interface
AG-E1 boards come configured either with a pair of 75 ohm BNC coaxial trunk connectors, or with single 120 ohm RJ48C connectors, as shown in Figure 8.
With AG-E1 120 ohm boards, a twisted pair modular cable with RJ48C connectors is supplied (shown in Figure 9). Also available is a loopback block, which you can use to connect the board's transmit channels to its receive channels for loopback testing (see section 2.10). With AG-E1 75 ohm boards, two 6-foot coaxial cables with male-to male BNC connectors are supplied (shown in Figure 12).
Figure 12: 75 ohm BNC Network Connectors
In each BNC connector, the center conductor is the TIP signal.
You can configure the AG-T1 or AG-E1 board in loopback mode to test your digital trunk application without actually connecting to the network. Figure 13 and Figure 14 show loopback configurations:
