C H A P T E R 1 Introduction Overview The Signaling System 7 (SS7) Gateway Configuration Tool (SS7Cfg) provides the interface to customize the SS7 gateway for a particular network installation. This tool is provided as a separate utility from the Intelligent Contact Management (ICM) setup since it requires specific knowledge of SS7 networks, nomenclature, and concepts.
Chapter 1 Introduction Before Using SS7Cfg This tool supports several different gateway types, including AIN, INAP, and Concert, which are all very similar. The only difference between these gateways is the way some of the parameters are configured in the application layer. Before Using SS7Cfg Before working with SS7Cfg, you should familiarize yourself with the setup and configuration of Cisco ICM software.
Chapter 1 Introduction Terminology • Message Transfer Part 2 (MTP2). Provides link-layer functionality with such capabilities as error-checking, flow control, and sequence checking. • Message Transfer Part 3 (MTP3). Extends the functionality of MTP2 to provide network layer functionality with such capabilities as node addressing, routing, alternate routing, and congestion control. • Network Interface Controller (NIC).
Chapter 1 Introduction Terminology Chapter 2, “Using SS7Cfg to Configure Your Gateway,” provides instructions on how to configure a gateway using a sample scenario. Cisco ICM Enterprise Edition SS7 Gateway Configuration Tool User Guide Release 6.
C H A P T E R 2 Using SS7Cfg to Configure Your Gateway Overview For the purposes of this exercise, the following sample network configuration will be used to set up an SS7 Generic (ITU) gateway using SS7Cfg. Note The example exercise configures the network interface from the bottom up, which is consistent with the way SS7Cfg was defined. (Notice that only Gateway 1 will be configured in this example.) In Figure 2-1, Gateway 1 has four links connecting to two different Signal Transfer Points (STPs).

Step 1 Right-click the Node parameter and select the Modify option from the shortcut menu.
Chapter 2 Using SS7Cfg to Configure Your Gateway Working in the Main Window The Edit Customer and Node names dialog box displays. Step 2 Enter the customer and node names in their respective text boxes. Step 3 Click OK. After setting the values, the configuration needs to be saved as a Registry file (*.reg). The changes will be reflected in the main window, as shown below. Cisco ICM Enterprise Edition SS7 Gateway Configuration Tool User Guide Release 6.
Chapter 2 Using SS7Cfg to Configure Your Gateway Saving the Configuration Saving the Configuration An important feature of SS7Cfg is that you can remotely edit and maintain regedit files (*.reg) that can then be imported to and exported from the NT Registry with the Windows regedit utility, without involving the ICM gateway site. Note Do not use files exported from Regedt32 because they use a different format for exported Registry files that is incompatible with the format for regedit files.
Chapter 2 Using SS7Cfg to Configure Your Gateway Saving the Configuration Step 2 The Save As dialog box displays. Enter the file name and select the SS7Cfg Files (*.reg) file type. At this point, the system performs a consistency check against the Registry file. For example, if there are no routes defined for the Remote Point Codes defined at MTP3, a message box displays asking if you would like to continue with the error, or go back and fix it. (One message box will display for each error detected.
Chapter 2 Using SS7Cfg to Configure Your Gateway Importing the Registry File In this case, clicking OK will save the configuration with errors to disk. Clicking Cancel will cancel the file save operation and allow you to continue editing to fix the configuration problem. Importing the Registry File Now that the gateway configuration has been saved as a Registry file, the final step of the configuration process can be performed by importing the file into the Registry using the regedit utility.
Chapter 2 Using SS7Cfg to Configure Your Gateway Importing the Registry File Step 3 Within this window, drill down to the HKEY_LOCAL_MACHINE\SOFTWARE\Cisco Systems, Inc.\ICM\\\SS7Gate folder. Step 4 Right-click the CurrentVersion registry key to display the following shortcut menu. Cisco ICM Enterprise Edition SS7 Gateway Configuration Tool User Guide Release 6.
Chapter 2 Using SS7Cfg to Configure Your Gateway Importing the Registry File Step 5 Select Rename and change the keyname to one that describes the save date, backup000329, as shown below.
