RADIO FREQUENCY INTERFERENCE STATEMENT:

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to TV or radio reception, which can be determined by turning the equipment on and off. The user is encouraged to try to correct the interference by one or more of the following methods:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

• Consult the dealer or an experienced radio/TV technician for help.

Changes or modifications to this unit not expressly approved by ADTRAN will void the user’s authority to operate the equipment.

CANADIAN EMISSIONS REQUIREMENTS

This digital apparatus does not exceed the Class B limits for radio noise emissions from digital apparatus as set out in the interference-causing equipment standard entitled "Digital Apparatus," ICES-003 of the Department of Communications.

Cet appareil nuerique respecte les limites de bruits radioelectriques applicables aux appareils numeriques de Class B prescrites dans la norme sur le materiel brouilleur: "Appareils Numeriques," NMB-003 edictee par le ministre des Communications.

CANADIAN EQUIPMENT LIMITATIONS

Notice: The Canadian Industry and Science Canada label identifies certified equipment. This certification means that the equipment meets certain telecommunications network protective, operational, and safety requirements. The Department does not guarantee the equipment will operate to the user’s satisfaction.

Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications company. The equipment must also be installed using an acceptable method of connection. In some cases, the company’s inside wiring associated with a single line individual service may be extended by means of a certified connector assembly (telephone extension cord). The customer should be aware that compliance with the above conditions may not prevent degradation of service in some situations.

Repairs to certified equipment should be made by an authorized Canadian maintenance facility designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.

Users should ensure for their own protection that the electrical ground connections of the power utility, telephone lines and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural areas.

Caution: Users should not attempt to make such connections themselves, but should contact the appropriate electric inspection authority, or an electrician, as appropriate.

The Load Number (LN) assigned to each terminal device denotes the percentage of the total load to be connected to a telephone loop which is used by the device, to prevent overloading. The termination on a loop may consist of any combination of devices subject only to the requirement that the total of the Load Numbers of all devices does not exceed 100.

INSTALLING THE ADTRAN EXPRESS XRT

Chapter 2

This section describes how to connect the Express XRT to a computer and how to install the Express Configuration Wizard software.

Verify Switch Settings

Dip switches 1 and 2 located on the rear panel of the Express XRT allow you to physically configure certain settings. Figure 2-1 on page 6 shows the location of the dip switches on the rear panel of the unit.

The factory default position for all switches is On (down) during initial installation.

SW 1: Off (up)

On (down)

If dip switch 1 is set to the Off position (up), the unit is set to operate at a DTE speed of 230.4 kbps. A special serial COM port using a 16650 UART is required while in this mode. If switch 1 is set to the On position (down), the unit will automatically adapt to the DTE rate (up to 115.2 kbps).

In order to configure the Express XRT to operate at 230.4 kbps with Windows 95 or Windows NT 4.0 Dial-Up Networking, a new modem must be added from the Modems icon in the Control Panel. Enter the name for this new connection and select ADTRAN Express XRT 230.4

Kbps & 16650 UART . See the section Installing Windows 95 Dial-Up

Networking on page 23 .

Basic Telephone Service

In addition to the computer connection, two analog devices such as a telephone, FAX, modem, or answering machine can be connected using the two POTS interfaces on the rear panel (RJ-11 jacks labeled 1 and 2 with a diagram of a telephone above the jack).

Supplementary Voice Services

Supplementary services such as call forwarding, caller ID, call return, call holding, three- or six-way conference, call transfer, call rejection, and call waiting are fully supported by the Express XRT on a touch-tone telephone. These services are available only if included in the ISDN line configuration and are implemented using the standard commands provided by the telephone company.

Call Waiting

Call Waiting permits one voice call to be placed on hold while answering another voice call. Use the flash-hook to place the active call on hold and answer an incoming call. Hanging up terminates both calls. The call waiting tone can be disabled and enabled using a touch-tone phone as follows:

Chapter 2. Installation

Disable call waiting: Press ** 0 Enable call waiting: Press ** 1

Conference Calling

Conference Calling (also known as three-way calling) permits a conversation between three parties, each at different locations.

During a voice call, the call waiting tone signals a second incoming call. Flash-hook to place the first call on hold and answer the incoming call. Flash-hook again to retrieve the first caller. A third flash-hook conferences all three parties.

To enable Call Conferencing, dial **2 before dialing the telephone number. This enables the Flash Hook button on your telephone to conference up to six people together. The dial code is only necessary when S37=0, when S37=1, or when the Flash Hook button will conference by default.

61202.153L3-1 Express XRT User Guide 13

Chapter 2. Installation

Automatic Redial

Automatic redial dials the last number dialed. This can be accomplished using a touch-tone phone as follows:

Redial last number: Press ** 5

When connecting to a National ISDN 1 switch, call conferencing, message waiting, and call transferring are assigned a unique feature identifier number. This number may not be the same in all areas. S-registers 90 and 91 contain the feature identifier numbers for conference and transfer. If these features do not work, contact your ISDN provider.

Phone Number Allocation

The Express XRT allocates ISDN phone number 1 to POTS port 1. Connect the primary telephone to POTS port 1 as shown in Figure 2-2 on page 7.

ISDN phone number 2 is shared by the RS-232 port and POTS port 2; therefore, only one can be used at a time.

ISDN data calls and external modem applications must be placed to ISDN phone number 2.

Single Phone Number Operation

For AT&T 5ESS point-to-point lines and other lines with a single phone number, incoming voice calls are routed to POTS port 2 to allow for use of either a modem or a telephone. Service on POTS port 1 is not available.

Configuring an External Analog Modem

If the modem does not support 230.4 kbps, dip switch 1 on the back panel of the Express XRT must be On (down) to install and use an external modem with the Express XRT. This limits the DTE speed to 115.2 kbps when using the Express XRT with an external modem. To re-enable the 230.4 kbps operation for ISDN connections, set dip switch 1 to the Off (up) position.

When using applications supporting Express XRT operation at

230.4 kbps with an external analog modem that does not support

230.4 kbps, attach the Express XRT to the high speed 16650 UART

COM port and connect the external modem to a separate COM port. This allows the Express XRT to operate at 230.4 kbps and the external modem to operate at the reduced speed.

Required External Analog Modem Settings

There is one setting in the external modem that is required before trying to enable the modem with the Express Configuration Wizard. The Carrier Detect signal from the modem should be set to Normal (track the CD signal). This can be accomplished by using the AT command AT&C1. AT commands can be entered into the modem using the following procedure:

Controlling an External Analog Modem

There are three options for enabling and disabling an external modem: the Express Configuration Wizard, the WIN 95/NT 4.0 Tool Tray Icon, or a terminal emulation package. See the section Ex- press Configuration Tray Tool Menu on page 22 for more information on enabling and disabling a modem.

Once the external analog modem is enabled, all further COM activity is transmitted to the external analog modem connected to the Express XRT modem port. The external analog modem RTS and CTS lines are switched over to the PC COM port directly when the Express XRT is commanded to enable the external modem port. This allows the external analog modem to provide flow control as normal.

When the external analog modem is disabled, all further COM port activity is processed by the ISDN terminal adapter within the Express XRT.

When you select the Call Waiting option, the phone will function like a standard phone with call waiting. When you select Conference, the ﬂash hook will connect up to six people via a conference call. See Call Waiting on page 13 and Conference Calling on page 13 for details.

Incoming Voice Call Options

These options specify how the Express XRT is to route incoming voice calls.

Call Routing

All Calls to DTE

Routes all calls to the RS-232 port, regardless of Call Type.

Speech calls to POTS

Routes calls with a Speech Call Type to the POTS ports. Calls with Data 56k, Data 64k, and Audio are routed to the RS-232 port.

Speech/Audio calls to POTS

Routes calls with Speech and Audio Call Types to the POTS ports. Calls with Data 56k and Data 64k are routed with the RS-232 port.

Enable Call Rejection List

Enabling this option conﬁgures the Express XRT to compare all incoming Speech and Audio calling party numbers to the list of ten numbers in the Incoming Voice Call Rejection List. If a match between the incoming calling party number and an entry in the Incoming Voice Call Rejection List is found, the Express XRT will not ring the POTS port. Generally the caller will experience a busy signal. A message in the Status Buffer is the only indication that a call has been rejected.

Enable Anonymous Call Rejection

This option enables rejection of calls where the calling party number is blocked. These numbers normally appear as Private on a Caller ID unit. When an incoming anonymous call is received, while Anonymous Call Rejection is enabled, the call will not ring the POTS ports. Generally the user will experience a busy signal. A message in the Status Buffer is the only indication that an anonymous call has been rejected.

Troubleshooting

TROUBLESHOOTING GUIDELINES

This section provides troubleshooting techniques to alleviate problems that may be encountered while operating the Express XRT. If problems persist contact ADTRAN technical support for assistance (see the back cover of this manual).

Power/Line LED is Off

This indicates a problem with the power to the unit. Verify that the power cord is connected to the Express XRT and is plugged into a known working electrical outlet. If the Euro ISDN switch is selected, this may also indicate that the power is on but the line is deactivated.

Power/Line LED Flashes and B1 and B2 LEDs are Off

This indicates a problem with the physical connection of the ISDN line from the local telephone company to the Express XRT.

1. Verify the large end of the RJ-45 to RJ-45 cable (included with the Express XRT) is connected to the ISDN connector on the rear panel of the Express XRT.

2. Verify the other end of the RJ-45 to RJ-45 cable is connected to the ISDN NT1.

3. Contact the local telephone service provider.

61202.153L3-1 Express XRT User Guide 53

Chapter 6. Troubleshooting

Power/Line LED, B1, and B2 LEDs Flash Green

This indicates a configuration problem. Verify the following information is correct:

• Switch Type

• Service Profile Identifiers (SPIDs) (used in North America only)

• ISDN Phone Numbers

This information can be viewed by choosing the Status Register button under the Diagnostics tab of the ADTRAN Express Configuration Wizard window or the Configuration Screen in the VT 100 menu system. The Link Status should indicate Link Up if all configuration information is correct and the unit is properly connected. If the link status is good and calls still can not be placed, review the section for Dial-Up Connection Problems on page 55.

Auto-Detect can be used under the Wizard button in the ADTRAN Express Configuration software (or by using the Auto-De- tect SPIDs/Switch option in the Configuration screen of the VT 100 menus) to automatically detect the SPIDs and the Switch Type. This only applies to North American switches.

1. Look for the following with the COM port setup:

• IRQ conflicts.

• Wrong DTE speed.

• Use Microsoft diagnostics (msd.exe) to verify the COM port

has 16550 UART (for speeds of 115.2 kbps and below) or a 16650 UART (for speeds up to 230.4 kbps).

• Proper COM driver is installed (not provided) to support

DTE speeds above 19.2 kbps.

2. Verify the correct protocol is selected:

• PPP or V.120 generally for Internet applications

• V.120 or Async BONDING for work-at-home

Power/Line LED, B1, and B2 LEDs flash green sequentially. After a software upgrade, if the Power/Line, B1 and B2 LEDs flash green in sequence, a problem occurred. Restart the download using the instructions in on page 49, If the download fails a second time, contact ADTRAN technical support.

54 Express XRT User Guide 61202.153L3-1

Chapter 6. Troubleshooting

Dial-Up Connection Problems

Many connection problems can be diagnosed by viewing the status buffer message returned from the ISDN network and the Express XRT. These messages are accessed by choosing the Status Buffer button in the Diagnostics tab of the ADTRAN Express Configuration window.

The Status buffer can also be accessed using the key sequence Ctrl+V in the VT 100 menu system. Issue the AT command AT!V from a terminal emulation package such as HyperACCESS to invoke the VT 100 menu system.

Auto-detect Switch/SPIDs Remains at Link Down

Auto-detect is only used in North America.

The Link Down condition persisting for longer than 15 minutes indicates a problem with the ISDN line provided from the telephone company. The ISDN physical layer device has not been able to synchronize to the network. Ensure the RJ-45 to RJ-45 cable is correctly installed between the Express XRT and the NT1 and that the Express XRT is powered on. Call the local telephone company and have them check the ISDN line for correct operation.

Express XRT Not Detected

If the Express Configuration Wizard cannot detect the Express XRT verify the following:

1. The Express XRT is powered on.

2. No other applications are running that could be using the COM port to which the Express XRT is attached. A Windows application does not have to be active to tie up a COM port. Be sure to check the Windows 95 Taskbar for any suspended applications (such as HyperTerminal and HyperACCESS) that may be using the COM port. If any are minimized, these must be closed before starting the Express Configuration Wizard.

3. If you are operating the Express XRT at 230.4 kbps, ensure that dip switch 1 on the rear panel is off (up). This is required for operation at 230.4 kbps. Also, confirm that the computer has a 16650 UART.

61202.153L3-1 Express XRT User Guide 55

Chapter 6. Troubleshooting

External Analog Modem Not Detected

If the Express Configuration Wizard cannot detect the external analog mode verify the following:

1. The external analog modem is powered on.

2. The external analog modem is properly installed and configured for use with the Express Configuration Wizard. See Con- figuring an External Analog Modem on page 30 for more details on the required settings.

Difficulty with 230.4 kbps Operation

If the Express XRT does not work when the DTE rate is set to 230.4 kbps inside Windows, verify the following:

1. Verify that dip switch 1 on the back of the Express XRT is set to off (up).

2. Verify that a high speed serial card with a 16650 UART is being used and the software drivers to support the extended baud rate tables are installed.

Dial-Up Networking Difficulty

If Windows 95 Dial-Up Networking cannot talk to the Express XRT, check the modem configuration for the Express XRT. Ensure the bit rate for the DTE is set correctly. If the PC is not equipped with a 16650 UART, then the fastest DTE operation speed is 115.2 kbps. Ensure the speed is not higher than the PC and modem can support.

AT Commands and S-Registers

AT COMMANDS

While a call is not established, the DTE port accepts AT commands. During this time, the CD signal is inactive. When a call is established, the port is used for data. This data mode is indicated by the CD signal active. The Express XRT can be configured and controlled with AT commands from a serial port similarly to analog modems.

To exit data mode and enter command mode, the serial port must transmit a proper escape sequence to the Express XRT. A specified time delay must occur between the last data character and the first escape sequence character. This is the guard time delay, and it can be changed by writing a value to the S12 register. The default value for the guard time is one second. For a valid escape sequence to occur, the DTE must transmit the escape code character three times in succession with delay between each character being less than the guard time. The default escape sequence is +++.

Appendix A

Once command mode is entered, AT commands can be transmitted to the Express XRT to configure most of the options, dial remote Express XRTs, or initiate tests to check both the Express XRT and the network connections. All command lines must begin with the AT character set in either capital or lower case letters. To return an active call to the on-line state type ATO.

The command line may contain a single command or a series of commands after the AT attention code. AT commands _L1 and

_L0 are exceptions and must be on a separate line followed by En- ter. When a series of commands is used, the individual com-

mands may be separated with spaces for readability. The

61202.153L3-1 Express XRT User Guide 57

Appendix A. AT Commands and S-Registers

maximum length for a command line is 40 characters. Each command line is executed by the Express XRT upon receipt of a terminating character. The default terminating character is a carriage return (ASCII 013), but it can be changed by writing a different value to register S3. Before the terminating character is transmitted, the command line can be edited by using the backspace character (ASCII 008) to erase errors so the proper commands can be entered.

Using an AT Command

Type AT followed by the letter of the command and numeric value of the setting desired and then press Enter. The following command returns the software version of the unit:

Using S-Registers

The configuration of the Express XRT can be changed or reviewed with S-registers. See the section S-Register List on page 63 for a description of each S-register and its corresponding range of values.
