Revised: December 16, 2010, OL-18092-11

This document provides the procedures you need to provision the components of the Cisco PGW 2200 Softswitch. The provisioning process described in this document applies to all solutions running Cisco PGW 2200 Softswitch Software Release 9.8.

How to Use this Guide

The MML commands in this document are examples that help to illustrate the provisioning procedures. However, there are many additional parameters, properties, and values that you should consider when you are provisioning your own network. For a complete list of all MML commands, components, parameters, properties, and values, see Cisco PGW 2200 Softswitch Release 9 MML Command Reference.


Note This document does not include instructions for dial plan provisioning. For dial plan information, see Cisco PGW 2200 Softswitch Release 9.8 Dial Plan Guide.

Before You Begin

You should perform the following tasks before using this guide:

Plan your network configuration thoroughly. A detailed network diagram is helpful for provisioning.

Set up your system hardware and install all required software. For more information, see the following documents:

Cisco PGW 2200 Softswitch Hardware Installation Guide

Cisco PGW 2200 Softswitch Release 9.8 Software Installation and Configuration Guide

Terminology

The following terms are used in this document:

Cisco PGW 2200 Softswitch host—Sun host server running Cisco PGW 2200 Softswitch software.

Cisco PGW 2200 Softswitch node—Active and standby pair of Cisco PGW 2200 Softswitch.

Simplex Cisco PGW 2200 Softswitch node—Node that uses a single Cisco PGW 2200 Softswitch host. Typically, such nodes are used for solution evaluation tests or for small installations. In this configuration, any loss of service in the Cisco PGW 2200 Softswitch host disrupts all call traffic.

Continuous-service Cisco PGW 2200 Softswitch node—Node that uses two Cisco PGW 2200 Softswitch hosts to prevent system downtime caused by failure of a single host. Calls in progress are maintained when one Cisco PGW 2200 Softswitch host fails. Continuous-service nodes use ITP-Ls to preprocess SS7 signaling and distribute signaling to both Cisco PGW 2200 Softswitch hosts. If a failover occurs, all stable calls are maintained. A continuous-service node may also be referred to as a fault-tolerant node or an active-standby PGW pair.

Provisioning Overview

You can provision the Cisco PGW 2200 Softswitch to perform either (or both) of the following functions in a telecommunications network:

Next Generation Network Softswitch

Signaling Border Element

Next Generation Network Softswitch

For solutions involving a next generation network (NGN) softswitch, configure 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 NGN configuration.


Note Most of the links shown in Figure 1-1 represent multiple connections between devices.


Figure 1-1 Typical NGN Application with 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, such as signal transfer points (STPs).

Configure connections between the Cisco PGW 2200 Softswitch and the media gateways (MGWs).

Configure connections between the Cisco PGW 2200 Softswitch and the IP Transfer Point (ITP) or the IP Transfer Point - Link Extenders (ITP-Ls).

You establish these connections by specifying parameter values for each of the entities illustrated in Figure 1-1 (Cisco PGW 2200 Softswitch hosts, STPs, ITP-Ls, MGWs, and all their associated links).

Signaling Border Element

For solutions involving a signaling border element (SBE), configure one or more Cisco PGW 2200 Softswitch hosts and the various network elements that provide SS7, SIP, and H.248 capabilities. Figure 1-2 shows a simplified layout of the entities that make up a Cisco PGW 2200 Softswitch solution in a typical continuous-service SBE configuration.


Note Most of the links shown in Figure 1-2 represent multiple connections between devices.


Figure 1-2 Typical Network Application with the Cisco PGW 2200 Softswitch as SBE

Provisioning prepares the Cisco PGW 2200 Softswitch software to communicate with other network elements, including SS7 elements, session border controllers (SBCs), and media gateways (MGWs). To provision your Cisco PGW 2200 Softswitch, you must

Configure communications between the Cisco PGW 2200 Softswitch and SBCs that function as data border elements (DBEs).

Configure connections between the Cisco PGW 2200 Softswitch and the MGWs.

You establish these connections by specifying parameter values for each of the entities illustrated in Figure 1-2.

Provisioning Prerequisites

The software installation procedure is provided in Cisco PGW 2200 Softswitch Release 9.8 Software Installation and Configuration Guide. The following steps summarize the basic procedure:

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.

Before you can provision the Cisco PGW 2200 Softswitch, you need to collect the following

information:

Device addresses

SS7 point codes

Information about external nodes

Trunk identification data


Note It is best to plan SS7 routes before you configure links, because you define APCs and linksets when defining routes, and you must plan and configure these components before you can configure links.


Provisioning Sequence

Provisioning tasks are performed in a sequence that can vary depending on your configuration. However, some provisioning tasks must be performed before others. We recommend the following provisioning sequence:

Add external nodes for each device connected to the network

Add IP gateway (for H.248 functions)

Add point codes

Add SS7 signaling service

Add media gateway signaling service

Add linksets

Add C7 IP links (redundant)

Add IP links

Add SS7 routes

Add SS7 subsystem

Add trunks (x24 or x31)

Add provisioning profiles

Add provisioning properties

Provisioning Tools

The Cisco PGW 2200 Softswitch includes the following provisioning tools:

Voice Services Provisioning Tool—A graphical provisioning tool.

Man-Machine Language—A command-line interface application.


Note You can use both Voice Services Provisioning Tool and Man-Machine Language to provision the Cisco PGW 2200 Softswitch, but not simultaneously.

Voice Services Provisioning Tool

Cisco VSPT is a graphical provisioning tool for the Cisco PGW 2200 Softswitch. Cisco VSPT allows you to

Create and modify network elements including signaling connections, trunk groups, trunks, routes, and dial plans.

Import and export configurations.

Generate MML commands.

For more information about VSPT, see Chapter 4, "Provisioning with the Cisco Voice Services Provisioning Tool" and Cisco Voice Services Provisioning Tool User Guide.

Man-Machine Language

MML is a command-line tool for the Cisco PGW 2200 Softswitch. There are two ways to use MML to configure the Cisco PGW 2200 Softswitch:

MML Commands—Individual provisioning commands that change on aspect of the configuration.

MML Batch file—You can upload and execute a batch file containing multiple MML commands or an entire configuration. This provisioning method can be useful for provisioning multiple devices.

For instructions on how to use MML, see Chapter 2, "MML Basics." and Cisco PGW 2200 Softswitch Release 9 MML Command Reference.
