Overview

This Technical Guide describes the installation and configuration of the components included in the N-Squared N2SCP platform.

Refer to the core n2svcd documentation for general principles of and documentation regarding the base components. The N2SCP documentation only describes its own delivered additional components.

This package adds two new applications to N2SVCD:

• DsgScpApp - Diameter/CAMEL Gateway N2DSG-SCP.
• LhoScpApp - general-purpose SCP Logic Hand-Off application.

The N2DSG-SCP is an out-of-the-box Diameter/CAMEL signalling gateway, which functions as a CAMEL/Diameter Interworking Function with additional enrichment features.

The N2LHO-SCP is a general-purpose “Logic Hand-Off SCP” component. It is deployed as part of a complete N2ACD-SCP (Automated Call Distribution “Toll-Free”) service, as well as being a critical component of other CAMEL/INAP Value-Added Services such as Number Portability, Voice VPN, and other site-specific services.

N2SCP Logical Components

N2SCP has several logical components:

• The runtime services engine (SVC) for call control using the N2SVCD platform.
• The Graphical User Interface (GUI): for performing administrative functions for CUG data.
• The API endpoint for performing administrative actions for CUG data.
• The Database (DB): persistent data storage for CUG data.

Each of these components can have multiple instances in a given deployment in order to provide service continuity or meet performance targets. They also may be installed separately or co-hosted with any other component. However, at least one instance of each core component is required for the N2SCP system as a whole to function.

If no CUG functionality is required, only the core SVC component is necessary.

N2SCP Packages

In order to provide its logical components, several packages are available:

N2SCP Installation

Installation instructions are provided for all N2SCP package types.

The root directory for all N2SCP package is /usr/share/n2scp. Some packages may install additional files in other locations; these are called out explicitly in individual installation instructions.
