Cisco Product Security Overview
Cisco Product Security Overview
Cisco provides a free online Security Vulnerability Policy portal at this URL:
http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html
From this site, you can perform these tasks:
• Report security vulnerabilities in Cisco products.
• Obtain assistance with security incidents that involve Cisco products.
• Register to receive security information from Cisco.
A current list of security advisories and notices for Cisco products is available at this URL:
http://www.cisco.com/go/psirt
If you prefer to see advisories and notices as they are updated in real time, you can access a Product
Security Incident Response Team Really Simple Syndication (PSIRT RSS) feed from this URL:
http://www.cisco.com/en/US/products/products_psirt_rss_feed.html
Reporting Security Problems in Cisco Products
Cisco is committed to delivering secure products. We test our products internally before we release them,
and we strive to correct all vulnerabilities quickly. If you think that you might have identified a
vulnerability in a Cisco product, contact PSIRT:
• Emergencies—security-alert@cisco.com
• Nonemergencies — psirt@cisco.com
Tip We encourage you to use Pretty Good Privacy (PGP) or a compatible product to encrypt any sensitive
information that you send to Cisco. PSIRT can work from encrypted information that is compatible with
PGP versions 2.x through 8.x.
Never use a revoked or an expired encryption key. The correct public key to use in your correspondence
with PSIRT is the one that has the most recent creation date in this public key server list:
http://pgp.mit.edu:11371/pks/lookup?search=psirt%40cisco.com&op=index&exact=on
In an emergency, you can also reach PSIRT by telephone:

Preface
Obtaining Technical Assistance
Cisco Technical Support Website
The Cisco Technical Support Website provides online documents and tools for troubleshooting and
resolving technical issues with Cisco products and technologies. The website is available 24 hours a day,
365 days a year, at this URL:
http://www.cisco.com/techsupport
Access to all tools on the Cisco Technical Support Website requires a Cisco.com user ID and password.
If you have a valid service contract but do not have a user ID or password, you can register at this URL:
http://tools.cisco.com/RPF/register/register.do
Note Use the Cisco Product Identification (CPI) tool to locate your product serial number before submitting
a web or phone request for service. You can access the CPI tool from the Cisco Technical Support
Website by clicking the Tools & Resources link under Documentation & Tools. Choose Cisco Product
Identification Tool from the Alphabetical Index drop-down list, or click the Cisco Product
Identification Tool link under Alerts & RMAs. The CPI tool offers three search options: by product ID
or model name; by tree view; or for certain products, by copying and pasting show command output.
Search results show an illustration of your product with the serial number label location highlighted.
Locate the serial number label on your product and record the information before placing a service call.
Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3
and S4 service requests are those in which your network is minimally impaired or for which you require
product information.) After you describe your situation, the TAC Service Request Tool provides
recommended solutions. If your issue is not resolved using the recommended resources, your service
request is assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:
http://www.cisco.com/techsupport/servicerequest
For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone.
(S1 or S2 service requests are those in which your production network is down or severely degraded.)
Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business
operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447
For a complete list of Cisco TAC contacts, go to this URL:
http://www.cisco.com/techsupport/contacts
Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity
definitions.
Severity 1 (S1)—Your network is “down,” or there is a critical impact to your business operations. You
and Cisco will commit all necessary resources around the clock to resolve the situation.

Preface
Obtaining Additional Publications and Information
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your
business operation are negatively affected by inadequate performance of Cisco products. You and Cisco
will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations
remain functional. You and Cisco will commit resources during normal business hours to restore service
to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or
configuration. There is little or no effect on your business operations.

About the Cisco IPVC 3540 PRI Gateway
The Cisco IPVC 3540 PRI Gateway consists of two modules that insert into a Cisco IPVC 3544 chassis:
the Cisco IPVC 3540 PRI Gateway module and the Rear Transition Module (RTM). The gateway
module installs in the front of the chassis and contains the gateway application apparatus. The RTM
installs in the rear of the chassis and contains the physical interface that connects to the PRI-service
provider equipment. You must install the gateway module and the RTM in corresponding slots. For
example, if you install the gateway module in slot 2 in the front of the chassis, you must install the RTM
in slot 2 in the rear of the chassis.
The Cisco IPVC 3544 chassis requires that the module installed in the top slot provide the system
controls for the cPCI bus. The gateway module has system capability, and can be installed in top slot of
the chassis or in one of the other slots. When you install a gateway module in the top slot, you must
replace the original RTM in the top slot in the rear of the chassis with a gateway RTM.

Chapter 1 Overview of the Cisco IPVC 3500 Series Gateway
About Cisco IPVC 3500 Series Gateway Features
ISDN rollover The Cisco IPVC 3500 Series Gateway features
ISDN rollover. In this feature, the gateway sends
a “busy out” channel request to the PSTN switch
when the current PRI connection is left with less
than a predefined number of available B channels.
The PSTN switch “rolls over” to the next
available gateway.
Note This feature is supported on the
CiscoIPVC3500PRIGateways only.
Network Specific Facility The Cisco IPVC 3500 Series Gateway provides
support for Network Specific Facility Information
Elements (NSF IEs) enables system
administrators to specify to service providers the
equipment, service, or network through which
they want a call routed.
Note This feature is supported on the
CiscoIPVC3500PRIGateways only.
ISDN connection failure The Cisco IPVC 3500 Series Gateway responds
to ISDN connection failure events, by
unregistering from its gatekeeper. The gatekeeper
is forced to send new IP-to-ISDN calls through a
different gateway, thus ensuring high call
completion rates. The gateway re-registers to the
gatekeeper when the ISDN connection is restored.
Downspeeding The Cisco IPVC 3500 Series Gateway features In
downspeeding functionality. In the downspeeding
feature, the Cisco IPVC 3500 Series Gateway
attempts to reconnect a disconnected video call
either at a lower bandwidth or as a voice call.
