Obtaining Technical Assistance
Preface
This preface describes the objectives, audience, organization, and conventions of this document, and explains how to find additional information on related products and services. It contains the following sections:

• Obtaining Technical Assistance
Document Objectives
This guide contains procedures for upgrading within the Cisco SS7 Interconnect for Access Servers and Voice Gateways Solutions. These procedures describe how to upgrade the following releases:
•From an installed Cisco SS7 Dial Access Solution (DAS) Release 2.0 to the Cisco SS7 Interconnect for Access Servers Solution Release 2.1 or 2.2
•Within a Cisco SS7 Interconnect for Access Servers Solution, from Release 2.1 to Release 2.2
•Within a Cisco SS7 Interconnect for Voice Gateways Solution, from Release 1.0 or 1.1 to
Release 1.3The Cisco SS7 Interconnect for Access Servers Solution is the second version of Cisco's solution that provides dial offload services to IP networks. The first version was the Cisco SS7 DAS.
To follow the procedures in this manual, you should be familiar with the signaling controller (SC), Man-Machine Language (MML), the UNIX operating system, and Cisco IOS software.
Note This guide uses SC host to refer to the combinations of Sun Microsystems, Inc. server hardware and SC software. The SC software supports other network solutions (in addition to the signaling controller) and is also called the Cisco Media Gateway Controller (MGC) Software. The software is also called the Cisco Telephony Controller Software.
These procedures are designed for upgrading both simplex (single) and high-availability configurations that contain two signaling controllers to provide switchover functions. In a simplex system, all call processing stops if an SC host fails. In the high-availability configuration, one host (active) is paired with a backup host (standby) that is designed to automatically take over as the active host if failure in call processing occurs.
In the Cisco SS7 Interconnect for Access Servers Solution, Cisco Systems recommends that signaling links no longer terminate in the A/B switch and ITK cards on the SC host, but be connected to Cisco Signaling Link Terminals (SLTs). Using the Cisco SLTs to terminate signaling provides a more robust and fault-tolerant system. A configuration using two SC hosts and two Cisco SLTs is a continuous-service configuration. A configuration using two SC hosts and ITK cards to terminate signaling is a high-availability configuration.
Note The cards referred to as "ITK" are manufactured by Digi International AG (formerly known as IT Telekommunikations AG [ITK]).

Technical Assistance Center
The Cisco Technical Assistance Center (TAC) is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two levels of support are available: the Cisco TAC Web Site and the Cisco TAC Escalation Center.
Cisco TAC inquiries are categorized according to the urgency of the issue:
•Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.
•Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.
•Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.
•Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.
The Cisco TAC resource that you choose is based on the priority of the problem and the conditions of service contracts, when applicable.
Cisco TAC Web Site
You can use the Cisco TAC Web Site to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to this URL:
All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to this URL to register:
http://www.cisco.com/register/
If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco TAC Web Site, you can open a case online by using the TAC Case Open tool at this URL:
http://www.cisco.com/tac/caseopen
If you have Internet access, we recommend that you open P3 and P4 cases through the Cisco TAC Web Site.
Cisco TAC Escalation Center
The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer automatically opens a case.
To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to this URL:
http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml
Before calling, please check with your network operations center to determine the level of Cisco support services to which your company is entitled: for example, SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA). When you call the center, please have available your service agreement number and your product serial number.
