This chapter provides an overview of the Cisco PGW 2200 Softswitch provisioning process and tools. It includes the following sections:
•Before You Begin

•Cisco PGW 2200 Softswitch Provisioning
•Cisco PGW 2200 Softswitch Provisioning Rules
•Cisco PGW 2200 Softswitch Provisioning Tools
The remaining chapters in this guide describe how to develop a provisioning plan and to provision your system using the tools provided with your Cisco PGW 2200 Softswitch software.
The provisioning process described in this document applies to all solutions running Cisco PGW 2200 Softswitch software Release 9.
Note This document does not include instructions for dial plan provisioning. For dial plan information, refer to the Cisco PGW 2200 Softswitch Release 9 Dial Plan Guide (through Release 9.7).
Before You Begin
You should have performed the following tasks before using this guide:
•Thoroughly plan your network configuration. A detailed network diagram is helpful when provisioning. For more information, refer to your solution's overview document.
•Set up your system hardware and install all required software. For more information, refer to the following documents:
–Cisco Media Gateway Controller Hardware Installation Guide
–Cisco Media Gateway Controller Software Release 8 Installation and Configuration Guide
Cisco PGW 2200 Softswitch Provisioning Overview
All solutions involving the Cisco PGW 2200 Softswitch are configured using one or more Cisco PGW 2200 Softswitch hosts, one or more Signaling System 7 (SS7) network signaling options, and one or more media gateways that control bearer-traffic routing. Figure 1-1 shows a simplified layout of the entities that make up a Cisco PGW 2200 Softswitch solution in a typical continuous -service configuration.
Note Most of the links shown Figure 1-1 represent multiple connections between devices.
Figure 1-1 Typical Solution Configuration Using the Cisco PGW 2200 Softswitch
Provisioning prepares the Cisco PGW 2200 Softswitch software to communicate with the SS7 network and with the media gateways. To provision your Cisco PGW 2200 Softswitch , you must:
•Configure communications between the Cisco PGW 2200 Softswitch and external SS7 signaling points (SPs), such as STPs
•Configure connections between the Cisco PGW 2200 Softswitch and the media gateways
You establish these connections by specifying parameter values for each of the entities illustrated in Figure 1-1 (Cisco PGW 2200 Softswitch hosts, ITP-Ls, STPs, media gateways, and all their associated links).
Cisco PGW 2200 Softswitch Provisioning
Provisioning tasks are performed in a sequence that can vary depending on your configuration. However, some provisioning tasks must be performed before certain other tasks are performed. The following list identifies a recommended provisioning sequence.
•Add external nodes for each device connected to the network
•Add point codes
•Add the interface cards
•Add SS7 signaling service
•Add media gateway signaling service
•Add C7 IP links (redundant)
•Add IP links
•Add SS7 routes
•Add SS7 subsystem
•Add trunks (x24 or x31)
Cisco PGW 2200 Softswitch Provisioning Rules
When provisioning the Cisco PGW 2200 Softswitch, the following rules apply.
•Install the software on the active host.
•Configure the software on the active host.
•Enable the Cisco PGW 2200 Softswitch software on the active host.
•Configure the Cisco PGW 2200 Softswitch software for the active host.
–Only one active provisioning session is permitted.
–Provisioning is only permitted on the active Cisco PGW 2200 Softswitch.
•Exit the provisioning session on the active host
If you have a standby host, set the pom.dataSync to true (in the XECfgParm.dat file) so that when started, the standby host synchronizes with the active host.
Note If the preceding rules are not followed the standby host will not be synchronized with the active host. As a result, a forced switchover may cause the switchover to fail.
Refer to the Cisco Media Gateway Controller Software Release 9 Installation and Configuration (Release 9.7) for information about installing the host software and the Cisco PGW 2200 Softswitch software.
Cisco PGW 2200 Softswitch Provisioning Tools
The Cisco PGW 2200 Softswitch includes two tools that you can use for provisioning:
•The Voice Services Provisioning Tool Version 2.3, (VSPT) graphical user interface (GUI) application.
•The Man-Machine Language (MML) command-line interface (CLI) application.
Note The Voice Services Provisioning Tool replaces the TCM and CMM provisioning tools of previous software releases.
The Cisco VSPT provides a GUI for the creation, modification, and execution of signaling connections, as well as trunk groups, trunks, routes, and dial plans. It also allows users to import existing configurations for modification and to download modified configurations to the same or different devices. To simplify operator tasks such as trunk group provisioning, the Cisco VSPT employs a series of wizard-style templates combined with a user interface that is tailored for provisioning the Cisco PGW 2200 Softswitch. Users can automatically generate the MML commands necessary to configure the appropriate network elements. Because much of the operator input information is common to the media gateways and the Cisco PGW 2200 Softswitch, the Cisco VSPT ensures that the information is entered once and then used to create the required MML commands. The resulting batch files are sent to the Cisco PGW 2200 Softswitch, updating the appropriate configuration records.
The VSPT is useful when initially provisioning your Cisco PGW 2200 Softswitch. An example of the Cisco VSPT GUI is shown in Figure 1-2. A comparison of the VSPT and MML features is included in Table 1-1.
Note The Cisco VSPT application may be deployed as an integrated component of the Cisco MGC Node Manager or as a standalone application. When integrated with Cisco MGC Node Manager, the VSPT application is launched directly from within Cisco MGC Node Manager.
For instructions on using the VSPT, see Chapter 3 "Provisioning with the Cisco Voice Services Provisioning Tool".
Figure 1-2 Sample Cisco Voice Services Provisioning Tool Window
You can also provision your Cisco PGW 2200 Softswitch by creating the MML command batch file manually without the aid of the VSPT. Although provisioning using this method requires more keystrokes, simple provisioning updates can sometimes be accomplished more quickly, because you do not have to go through the process of launching the VSPT. When you enter MML commands manually into a batch file, you can copy and paste repetitive commands to speed data entry. You can also copy and modify existing MML scripts (lists of MML commands) to provision additional devices. An example of an MML command script is included in Example 1-1.
Provisioning using MML commands is recommended for more-experienced users. A comparison of the VSPT and MML features is included in Table 1-1.
For information on provisioning with MML, refer to Chapter 4 "MML Basics."
Example 1-1 Sample MML Script
Note You can use both Voice Services Provisioning Tool and MML to provision the Cisco PGW 2200 Softswitch; however, only a single configuration session can be supported at one time.

System Hardware/Software Requirements
Sun Sparc station running Sun Solaris 2.6 OS, or later.
Note Running the VSPT on the same server as the Cisco PGW 2200 Softswitch can adversely impact performance. We recommend that you use a separate server.

Batch File Support
Best Used For
•Setting up a single configuration or few configurations on individual machines.
•Modifying an existing configuration.
•Creating batch files to configure many Cisco PGW 2200 Softswitch servers or to retrieve measurements.
•Scaling large configurations.
