Implementation Task List
To implement your Cisco SS7 Interconnect for Voice Gateways Solution, you must:
Step 1 Design your network by identifying the physical configuration and components of your network. This network design should be based on assumptions that meet your network requirements. Plan your design to include the following:
•Signaling routes to external switches
•Signaling links to signaling points
•Network access server control links
•Trunks, trunk groups, and QoS packet network routes
See the Cisco Media Gateway Controller Software Release 7 Provisioning Guide for details.
Step 2 Create a dial plan. See the Cisco Media Gateway Controller Software Release 7 Provisioning Guide for details.
Step 3 Connect the signaling controller hardware. See the "Hardware Installation" section for details.
Step 4 Connect the Cisco SLT and LAN switch to the signaling controller. See the "Hardware Installation" section for details.
Step 5 Install the operating system software and signaling controller software on the signaling controller host. See the "Signaling Controller Software Installation" section for details.
Step 6 Configure the software on the signaling controller. See the "Configuring the Signaling Controller" section for details.
a. Assign an IP address to the signaling controller and then create and deploy the configuration file on the signaling controller.
b. Configure the TCM 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 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 (Optional)" section for details.
Step 9 Install the access gateway. See the "Gateway Installation and Configuration" section for details.
a. Connect the access gateway to the LAN switch.
b. Connect the access gateway to the Public Switched Telephone Network (PSTN).
c. Configure and assign IP addresses to the access gateways. See the section "Gateway Installation and Configuration" for details.
Step 10 Configure the network management system, if installed for your Cisco SS7 Interconnect for Voice Gateways Solution, for its connectivity with the Cisco SC2200.
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 such software) each device from the other devices.

Operation and Maintenance
Under normal conditions, the primary (active) signaling controller application (MTP3 and the Call Processing Engine) processes calls. In addition to normal call processing, in a fault-tolerant 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 signaling controller. For detailed instructions on these operation procedures and maintenance tasks, see the Cisco Media Gateway Controller Operations, Maintenance, and Troubleshooting Guide.
•Managing signaling channels and lines
•Managing traffic channels
•Managing switchover
The following are operating procedures under various equipment failure scenarios:
•Signaling link termination failure
•Call processor failure
•Operating system failure
•LAN switch failure
The following are maintenance tasks necessary for each component in your Cisco SC2200:
•Checking equipment status
•Preventive maintenance
•Removing the component from your system
•Replacing the component
Configuring Other Components
Refer to the documentation that shipped with a particular component for configuration information.
