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 malicious access to or use of) your company’s telecommunications equipment by some party.

Your company's “telecommunications equipment” includes both this Avaya product and any other voice/data/video equipment that could be accessed via 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-multiplexedand/orcircuit-based),or asynchronous(character-,message-,orpacket-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, regardless of motive or intent)

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 documents

System administration documents

Security documents

Hardware-/software-basedsecurity 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-providedtelecommunications systems and their interfaces

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

Any other equipment networked to your Avaya products

Federal Communications Commission Statement

Part 15:

Note: 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 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 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 correct the interference at his own expense.

Part 68: Answer-SupervisionSignaling

Allowing this equipment to be operated in a manner that does not provide proper answer-supervisionsignaling is in violation of Part 68 rules. This equipment returnsanswer-supervisionsignals 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-supervisionsignals 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 attests that this registered 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 dialing codes is a violation of the Telephone Operator Consumers Act of 1990.
