This guide contains procedures for upgrading an installed Cisco SS7 Dial Access Solution Release 2.0 to the Cisco SS7 Interconnect for Access Servers Solution Release 2.0 or 2.1. The Cisco SS7 Interconnect for Access Servers Solution is the second release of Cisco's solution that provides dial offload services to IP networks. The first release was the Cisco SS7 Dial Access Solution (DAS).
 |
Note To upgrade from the Cisco SS7 Interconnect for Access Servers Solution Release 2.1 to Release 2.2, you must upgrade the Cisco Telephony Controller Software Release 7.3(x) to Cisco Media Gateway Controller Software Release 7.4(x). Refer to Chapter 2, Installing the Cisco Media Gateway Controller Software, in the Cisco Media Gateway Controller Software Release 7 Installation and Configuration Guide for instructions. |
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]). |
