6 6 PSTN Survivability This use case describes the configuration of PSTN Survivability with the Mediatrix unit located in the LAN. When PSTN survivability is configured it implies that: The Mediatrix unit is setup as a demarcation point. When SIP trunk fails, calls go through the unit's PRI or FXO port. The Mediatrix unit may or may not register to the SIP trunk. The PBX may or may not register to the Mediatrix unit. The Mediatrix unit is located in the LAN, behind a Near-End NAT. Getting Started 1) Make sure the WAN network interface (either WAN, ETH1, Ethernet, Network, or ETH5 depending on your model) of your Mediatrix unit is connected to the network. 2) Make sure the second Ethernet connector (either LAN, ETH2, or Computer depending on your model) of your Mediatrix unit is connected to the computer. 3) Log on to the Mediatrix unit Management interface. Note: If you are using your Mediatrix unit for the first time, refer to its Mediatrix unit Quick Start guide.

7 7 Logging On to the Mediatrix Unit Web Interface (p. 7) Logging On to the Mediatrix Unit Web Interface For better performances, it is recommended to use the latest available version of Microsoft Internet Explorer, Google Chrome or Mozilla Firefox. Note: You may not be able to log on to the Management Interface if you are using older browser versions. The computer's network card must be on the same subnet as the Mediatrix unit. 1) In your web browser, enter the IP address used by your Mediatrix unit to communicate with the Management Interface. If your computer is connected to the Ethernet port, commonly used to be connected to the Local Area Network (LAN), i.e. ETH2 on most devices, use the IP address. If your Mediatrix unit is configured to use a DHCP with IPv4, use the DHCP- provided IP address. 2) Enter public as your username and leave the password field empty. Note: The public username account has administrator rights. Note: You can also use admin as a username and administrator as password. 3) Click Login.
