This chapter describes how to implement the Cisco SS7 PRI Gateway Solution by installing and configuring the components. The following sections describe the tasks:
To implement your Cisco SS7 PRI Gateway Solution, follow the steps below:
See the Cisco Media Gateway Controller Software Release 7 Provisioning Guide and the
Cisco SS7 PRI Gateway Solution Provisioning Guide for details.
Step 2 Create a dial plan. See the Cisco Media Gateway Controller Software Release 7 Provisioning Guide and the Cisco SS7 PRI Gateway Solution Provisioning Guide for details.
Step 3 Connect the VSC host hardware. See the "Cisco Media Gateway Controller Hardware Installation" section on page 4-2 for details.
Step 4 Connect the VSC host and LAN switch. See the "Cisco Media Gateway Controller Hardware Installation" section on page 4-2 for details.
Step 5 Install the operating system software and Cisco VSC software on the VSC host. See the "VSC Host Software Installation" section on page 4-3 for details.
Step 6 Configure the software on the VSC host. See the "Configuring the VSC Host" section on page 4-3 for details.
a. Assign an IP address to the VSC host and then create and deploy the configuration file on the virtual switch controller.
b. Configure the Cisco Voice Service Provisioning Tool server and assign an IP address to the server.
Step 7 Configure the software on the Cisco SLT. See the "Configuring the Cisco SLT" section on page 4-6 for details.
Step 8 Configure the software on the LAN switch. If you are using a Cisco Catalyst switch, see the "Configuring the LAN Switch" section section on page 4-7 for details.
Step 9 Install the Cisco MGX 8260. See the "Cisco MGX 8260 Installation and Configuration" section on page 4-7 for details.
a. Connect the Cisco MGX 8260 to the LAN switch.
b. Connect the Cisco MGX 8260 to the public switched telephone network (PSTN).
c. Configure and assign IP addresses to the Cisco MGX 8260s. See the section "Cisco MGX 8260 Installation and Configuration" section section on page 4-7 for details.
Step 10 Configure the network management server. See the "Operations and Management" section on page 4-9 for details.
Step 11 Make sure that all the devices can talk to each other, by pinging one device from another. For example, you should be able to ping the media router and the DNS server (node in the internet cloud) from each device. You should also be able to access (using Telnet, ReflectionX, or other software) each device from the other devices.
Table 4-1 provides an overview of the recommended hardware connection sequence. For details, refer to the Cisco Media Gateway Controller Hardware Installation Guide. Make sure that you have the hardware installation guides handy for all the devices you are connecting in your system.

Configuring the VSC host software consists of three tasks:
 |
Caution Always use the Interim Provisioning Tool or MML commands to create, modify, manage, and deploy your configuration files on the VSC host. We do not recommend modifying the configuration files directly on the VSC host. |
Table 4-3 provides the VSC host configuration sequence.
| Step | Task | Reference |

This section describes the task of configuring LAN switches (Cisco Catalyst Switch family) for your solution. The LAN switch connects the VSC hosts to the Cisco MGX 8260s or the Cisco SLTs. The LAN switch is used in the VSC node to extend VLANs across platforms through backbone Fast Ethernet, gigabit, or ATM connections, when necessary. The LAN switch is not provided with the VSC host. Table 4-5 provides the LAN switch configuration sequence.

Under normal conditions, the primary (active) signaling controller application (MTP3 and Call Processing Engine) processes calls. In addition to normal call processing, in a redundant configuration the primary signaling controller updates the standby signaling controller with call state information when a call enters the establish phase. This ensures that the call state is maintained in case of failure.
The following are normal operating procedures for the VSC:
The following are operating procedures under equipment failure scenarios:
The Cisco SS7 PRI Gateway Solution components can be managed by using four different interfaces:
The Voice Service Provisioning Tool provides element management for the virtual switch controller, the Cisco MGX 8260, and the Cisco SLTs. The Voice Service Provisioning Tool is used to provision the
Cisco MGX 8260. These tools are used separately to manage and provision their corresponding network elements. The Cisco MGC Node Manager (CMNM) is also capable of capturing Cisco MGX 8260 alarms and allowing event correlation at the solution level.
The provisioning tool supports:
