							FCC CLASS A VERIFICATION STATEMENT
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to 
Part 15 of 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 instruction manuals, may 
cause harmful interference to radio communications. Operation of this equipment in a residential area is 
likely to cause harmful interference, in which case the user will have to correct the interference at his or her 
own expense.
Changes or modifications not expressly approved by 3Com could void the user’s authority to operate this 
equipment.
This equipment complies with Part 68 of the FCC rules. This unit bears a label which contains the FCC 
registration number and Ringer Equivalency Number (REN). If requested, this information must be provided to 
the telephone company.
This equipment uses the following standard FCC Part 68-compliant jacks and plugs for network connections:
USOC RJ11C for connecting to the telephone network
USOC RJ45 and BNC connectors for connecting to the local area network
This equipment contains FCC-compliant modular jacks. It is designed to be connected to the telephone 
network or premises wiring using compatible modular plugs and cabling which comply with the 
requirements of FCC Part 68 rules.
The Ringer Equivalency Number (REN) is used to compute the number of devices that can be connected to a 
telephone line. An excessive REN value on a line can result in the devices not ringing in response to incoming 
calls. In most, but not all areas, the sum of the RENs should not exceed five (5.0). To be certain of the number 
of devices that may be connected to a line, as determined by the total RENs, contact the local telephone 
company. For products approved after July 23, 2001, the REN for this product is part of a product identifier 
that has the format US:AAAEQ##TXXXX. The digits represented by ## are the REN without a decimal point 
(for example, 03 is a REN of 0.3). For earlier products, the REN is separately shown on the label.
In the unlikely event that this equipment causes harm to the telephone network, the telephone company can 
temporarily disconnect your service. The telephone company will try to warn you in advance of any such 
disconnection, but if advance notice is not practical, it may disconnect the service first and notify you as soon 
as possible afterwards. In the event that such a disconnection is deemed necessary you will be advised of your 
right to file a complaint with the FCC.
From time to time, the telephone company may make changes in its facilities, equipment, operations, or 
procedures which could affect the operation of this equipment. If this occurs, the telephone company is 
required to provide you with advance notice so you can make the modifications necessary to maintain 
uninterrupted service
Repairs to this equipment can be made only by the manufacturer or its authorized agents. In the event that 
this equipment requires service, contact your equipment vendor or the manufacturer, 3Com Corporation.
NBX Telephones are compatible with inductively coupled hearing aids.
If trouble is experienced with this NBX equipment, for repair or warranty information, please contact 3Com 
Corporation, 5400 Bayfront Plaza, P.O. Box 58145, Santa Clara, California, USA, Telephone: 800-NET-3Com 
or visit the website at www.3com.com. If the equipment is causing harm to the telephone network, the 
telephone company may request that you disconnect the equipment until the problem is resolved.
Connection to party line service is subject to state tariffs. Contact the state public utility commission, public 
service commission or corporation commission for information.
If your home has specially wired alarm equipment connected to the telephone line, ensure the installation of 
this NBX equipment does not disable your alarm equipment. If you have questions about what will disable 
alarm equipment, consult your telephone company or a qualified installer.
This equipment is capable of providing users access to interstate providers of operator services through the 
use of access codes. Modification of this equipment by call aggregators to block access to dialing codes is a 
violation of the Telephone Operators Consumers Act of 1990. 
						

							INDUSTRY CANADA NOTICE
NOTICE: The Industry Canada (IC) label identifies certified equipment. This certification means that the 
equipment meets the telecommunications network protective, operational, and safety requirements as 
prescribed in the appropriate Terminal Equipment Technical Requirements document(s). The department 
does not guarantee the equipment will work 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. The user should be aware that compliance with the above conditions might not prevent 
degradation of service in some situations.
Repairs to certified equipment should be coordinated by a representative 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 electrical inspection authority or electrician, as appropriate.
NOTICE: The Ringer Equivalency Number (REN) assigned to each terminal device provides an indication of the 
maximum number of terminals allowed to be connected to a telephone interface. The termination of an 
interface may consist of any combination of devices subject only to the requirement that the sum of the 
ringer equivalency numbers of all devices does not exceed 5.
