							FCC WARNING STATEMENT
Federal Communications commission (FCC) Rules require that you be notified of the following:
l       this equipment generates, uses, and can radiate radio frequency energy and, if not installed and
used in accordance with the instruction manual, may cause interference to radio
communications.
l       It has been tested and found to comply with the limits for a Class A computing device pursuant
to Subpart J of Part 15 of FCC Rules, which are designed to provide reasonable protection
against such interference when operated in a commercial environment.
l       Operation of this equipment in a residential area is likely to cause interference in which case the
user at his or her own expense will be required to take whatever measures may be required to
correct the interference.
SECURITY OF YOUR SYSTEM—PREVENTING TOLL FRAUD
As a customer of new telephone system, you should be aware that there exists an increasing
problem of telephone toll fraud. telephone toll fraud can occur in many forms, despite the numerous
efforts of telephone companies and telephone equipment manufacturers to control it. some
individuals use electronic devices to prevent or falsify records of these calls. Others charge calls to
someone else’s number by illegally using lost or stolen calling cards, billing incorrect parties,
clipping on to someone else’s line, and breaking into someone else’s telephone equipment physically
or electronically. In certain instances, unauthorized individuals make connections to the telephone
network through the use of remote access features.
The Remote Access feature of your system, if you chose to utilize it, permits off-premises callers to
access the system from a remote telephone by using an 800 number or a 7- or 10- digit telephone
number. the system returns an acknowledgment signaling the user to key in his or her authorization
code, which is selected and administered by the system manager. After the authorization code is
accepted, the system returns dial tone to the user. If you do not program specific egress restrictions,
the user will be able to place any call normally dialed from a telephone associated with the system.
Such an off-premises network call is originated at, and will be billed from, the system location.
The Remote Access feature, as designed, helps the customer, through proper administration, to
minimize the ability of unauthorized persons to gain access to the network. Most commonly, phone
numbers and codes are compromised when overheard in a public location, through theft of a wallet
or purse containing access information, or through carelessness (writing codes on a piece of paper
and improperly discarding it). Additionally, hackers may use a computer to “dial” an access code
and then publish the information to other hackers. Enormous charges can be run up quickly. It is
the customer’s responsibility to take the appropriate steps to properly implement the features,
evaluate and administer the various restriction levels, protect access codes, and distribute access
codes only to individuals who have been fully advised of the sensitive nature of the access
information.

							Common carriers are required by law to collect their tariffed charges. While these charges are
fraudulent charges made by persons with criminal intent, applicable tariffs state that the customer
of record is responsible for payment of all long-distance or other network charges. AT&T cannot
be responsible for such charges and will not make any allowance or give any credit for charges
that result from unauthorized access.
To minimize the risk of unauthorized access to your communications system:

l
Use a nonpublished Remote Access number.
Assign authorization codes randomly to users on a “need-to-have” basis, keeping a log of
ALL authorized users and assigning one code per person.
Use random sequence authorization codes, which are less likely to be broken.
Deactivate all unassigned codes promptly.
Ensure that Remote Access users are aware of their responsibility to keep the telephone
numbers and any authorization codes secure.
When possible, restrict the off-network capability of off-premises callers, via use of Call
Restrictions and Disallowed List capabilities.
When possible, block out-of-hours calling.
Frequently monitor system call detail reports for quicker detection of any unauthorized or
abnormal calling patterns.
Limit Remote Call Forward to persons on a “need-to-know” basis.
DANGER
