Preventing Toll Fraud

"Toll fraud" is the unauthorized use of your telecommunications system
by an unaut horized party (for example, a person who is not a corporate
employee, agent, subcontractor, or is not working on your company's
behalf). Be aware that there may be a risk of toll fraud associated with
your system and that, if toll fraud occurs, it can result in substantial
additional charges for your telecommunications services.

Avaya Fraud Intervention

If you suspect that you are being victimized by toll fraud and you need
technical assistance or support, in the United States and Canada, call the
Technical Service Center's Toll Fraud Intervention Hotline at
1-800-643-2353.

Providing Telecommunications Security

Telecommunications security (of voice, data, and/or video
communications) is the prevention of any type of intrusion to (that is,
either unauthorized or malicio us access to or use of) your company's
telecommunications equ ipm ent by some part y.

Your company's "telecommunications equipment" includes both this
Avaya product and any other voice/data/video equipment that could be
accessed using this Avaya product (that is, "networked equipment").

An "outside party" is anyone who is not a corporate employee, agent,
subcontractor, or is not working on your company's behalf. Whereas, a
"malicious party" is anyone (including someone who may be otherwise
authorized) who accesses your telecommunications equipment with
either malicious or mischievous intent.

Such intrusions may be either to/through synchronous (time-multiplexed
and/or circuit-based), or asynchronous (character-, message-, or
packet-based) equipment, or interfaces for reasons of:

• Utilization (of capabilities special to the accessed equipment)

• Theft (such as, of intellectual property, financial assets, or toll
facility access)

• Eavesdropping (privacy invasions to humans)

• Mischief (troubling, but apparently innocuous, tampering)

• Harm (such as harmful tampering, data loss or alteration,

Be aware that there may be a risk of unauthorized intrusions associated
with your system and/or its networked equipment. Also realize that, if
such an intrusion should occur, it could result in a variety of losses to your
company (including but not limited to, human/data privacy, intellectual
property, material assets, financial resources, labor costs, and/or legal
costs).

Responsibility for Your Company’s Telecommunications Security

The final responsibility for securing both this system and its networked
equipment rests with you - Avaya’s customer system administrator, your
telecommunications peers, and your managers. Base the fulfillment of
your responsibility on acquired knowledge and resources from a variety
of sources including but not limited to:

• Installation docume nts

• System administration documents

• Security documents

• Hardware-/software-based security tools

• Shared information between you and your peers

• Telecommunications security experts

To prevent intrusions to your telecommunications equipment, you and
your peers should carefully program and configure:

• Your Avaya-provided telecommunications systems and their
interfaces

• Your Avaya-provided software applications, as well as their
underlying hardware/software platforms and interfaces

• Any other equipment networked to your Avaya products

Part 15:

Note: This e qui pm en t ha s b ee n te ste d a nd fo un d t o c omp ly w it h
the limit s for a Class A 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 w ith the instruction
manual, 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 be required to cor rect the interference at his own
expense.

Part 68: Answer-Supervision Signaling

Allowing this equipment to be operated in a manner that does not provide
proper answer-supervision signaling is in violation of Part 68 rules. This
equipment returns answer-supervision signals to the public switched
network when:

• answered by the called station,

• answered by the attendant, or

• routed to a recorded announcement that can be administered
by the customer premises equipment (CPE) user.

This equipment returns answer-supervision signals on all direct inward
dialed (DID) calls forwarded back to the public switched telephone
network. Permissible exceptions are:

• A call is unanswered.

• A busy tone is received.

• A reorder tone is received.

Avaya at test s tha t thi s r egis te red eq ui pmen t is cap ab le o f pr ovid in g user s
access to interstate providers of operator services through the use of
access codes. Modification of this equipment by call aggregators to block
access dialing codes is a violation of the Telephone Operator Consumers
Act of 1990.

REN Number
For MCC1, SCC1, CMC1, G600, and G650 Media Gateways:

This equipment complies with Part 68 of the FCC rules. On either the
rear or inside the front cover of this equipment is a label that contains,
among other information, the FCC registration number, and ringer
equivalence number (REN) for this equipment. If requested, this
information must be provided to the telephone company.

For G350 and G700 Media Gateways:

This equipment complies with Part 68 of the FCC rules and the
requirements adopted by the ACTA. On the rear of this equipment is a
label that contains, among other information, a product identifier in the
format US:AAAEQ##TXXXX. The digits represented by ## are the ringer
equivalence number (REN) without a decimal point (for example, 03 is a
REN of 0.3). If requested, this number must be provided to the telephone
company.

For all media gateways:

The REN is used to determine the quantity of devices that may be
connected to the telephone line. Excessive RENs on the telephone line
may result in devices not ringing in response to an incoming call. In most,
but not all areas, the sum of RENs should not exceed 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.

REN is not required for some types of analog or digital facilities.

For all media gateways:

If the terminal equipment (for example, the media server or media
gateway) causes harm to the telephone network, the telephone company
will notify you in advance that temporary discontinuance of service may
be required. But if advance notice is not practical, the telephone
company will notify the customer as soon as possible. Also, you will be
advised of your right to file a complaint with the FCC if you believe it is
necessary.

The telephone company may make changes in its facilities, equipment,
operations or procedures that could affect the operation of the
equipment. If this happens, the telephone company will provide advance
notice in order for you to make necessary modifications to maintain
uninterrupted service.

If trouble is experienced with this equipment, for repair or warranty
information, please contact the Technical Service Center at
1-800-242- 2121 or contact your local Avaya representative. 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.
