FEDERAL COMMUNICATIONS COMMISSION
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 in a
residential 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 radio or TV reception,
which can be determined by turning the equipment off and on. The user is
encouraged to try to correct the interference by one or more of the following
measures:
• 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 not expressly approved by
ADTRAN will void the user’s authority to operate this
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 Depart-
ment 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 permis-
sible 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 Cana-
dian maintenance facility designated by the supplier. Any repairs or
alterations made by the user to this equipment, or equipment malfunc-
tions, 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 them-
selves, 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 require-
ment that the total of the Load Numbers of all devices does not exceed
100.

Chapter 1. Introduction
2Express XR/XRT Quick Start Guide 61200.0153L1-13
Before getting started, review the section Minimum Requirements
in this chapter to ensure your computer is compatible. In
addition, examine the contents of the box to ensure everything
has been received undamaged and gather the required setup
information provided by your telephone company.
MINIMUM REQUIREMENTS
What You Provide
In order to operate the Express XR/XRT the following is re-
quired:
• A computer (386 or higher PC, or Macintosh)
• Windows 3.1 or higher for PC
• 16550 UART high speed serial port (16650 UART required for
data speed of 230.4 kbps)
• RS-232 serial cable with a DB-25 connector for the Express XR/
XRT and the other end matching the COM port on the com-
puter (Do not use a null modem cable)
• One Basic Rate ISDN line (Two ISDN phone numbers, some-
times referred to as local directory numbers)
Single ISDN phone number and point-to-point lines are not recom-
mended for use with the XRT.
Basic Rate ISDN Line
When ordering your ISDN line from the telephone company,
request EZ-ISDN 1 (Capability Package U) to ensure it is set up
properly. EZ-ISDN 1 is recommended by the industry for most
home office/small business applications. If EZ-ISDN is not
available from your service provider order Generic Data M. For
more information regarding ordering ISDN, see the ADTRAN
document Ordering ISDN Service User Guide part number
60000.015-8, or contact the telephone company for alternative
line configurations. The Ordering ISDN Service User Guide is
available on the ADTRAN home page at http://www.adtran.com

Installation
INSTALLING THE ADTRAN EXPRESS XR/XRT
This section describes how to connect the Express XR/XRT to a
PC and how to install the Express Configuration Wizard soft-
ware.
Verify Switch Settings
Dip switches 1 and 2 located on the rear panel of the Express
XR/XRT allow certain settings to be physically configured.
Figure 2-1 shows the location of the dip switches on the rear
panel of the unit.
The factory default position for all switches is down (On) during initial
installation.
SW 1: Off (Up) = 230.4 kbps
On (Down) = Autobaud (speeds up to 115.2 kbps)
If switch 1 is set to the Off position, 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, the unit will automatically adapt to the DTE
rate (up to 115.2 kbps).
In order to configure the Express XR/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
XR or XRT 230.4 Kbps & 16650 UART. See the section Installing
Windows 95 Dial-Up Networking.

Chapter 2. Installation
6Express XR/XRT Quick Start Guide 61200.153L1-13
SW 2: Off (Up) = Factory Default
On (Down) = Normal (previous settings saved)
If Switch 2 is set to the Off position, the unit continues to use the
factory default settings until Switch 2 is set to the On position.
Also, area code, phone numbers, SPIDS, and stored numbers are
cleared.
Express XRT Only:
SW 3: Off (Up) = Phone Volume Loud
On (Down) = Phone Volume Normal
SW 4: Reserved for future use.
