TATEMENT
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
