Preventing Toll Fraud 
“Toll fraud” is the unauthorized use of your telecommunications system by an 
unauthorized party (for example, a person who is not a corporate employee, 
agent, subcontractor, or 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 telecommunica-
tions services.
Lucent Technologies Fraud Intervention
If you suspect you are being victimized by toll fraud and you need technical sup-
port or assistance, call the appropriate BCS National Customer Care Center tele-
phone number. Users of the MERLIN®, PARTNER®, and System 25 products 
should call 1 800 628-2888. Users of the System 75, System 85, DEFINITY® 
Generic 1, 2 and 3, and DEFINITY® ECS products should call 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 mali-
cious access to or use of your company’s telecommunications equipment) by 
some party.
Your company’s “telecommunications equipment” includes both this Lucent 
product and any other voice/data/video equipment that could be accessed via this 
Lucent product (that is, “networked equipment”).
An “outside party” is anyone who is not a corporate employee, agent, subcon-
tractor, or 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) equip-
ment 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 intru-
sion should occur, it could result in a variety of losses to your company (includ-
ing, but not limited to, human/data privacy, intellectual property, material assets, 
financial resources, labor costs, and/or legal costs).
Your Responsibility for Your Company’s Telecommunications Security
The final responsibility for securing both this system and its networked equip-
ment rests with you – a Lucent customer’s system administrator, your telecom-
munications 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-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:
Lucent-provided telecommunications systems and their interfaces
Lucent-provided software applications, as well as their underlying hard-
ware/software platforms and interfaces
Any other equipment networked to your Lucent products
Lucent Technologies does not warrant that this product or any of its networked 
equipment is either immune from or will prevent either unauthorized or mali-
cious intrusions.  Lucent Technologies will not be responsible for any charges, 
losses, or damages that result from such intrusions.
