PMG5318-B20A User’s Guide

The PMG5318-B20A combines a fiber optic (GPON) router with a built-in switch. Its voice over IP 
(VoIP) capabilities allow you to use a traditional analog telephone to make Internet phone calls.

Use the GPON Device’s built-in Web Configurator to manage it. You can connect to it using a web 
browser such as Firefox 2.0 (and higher) or Internet Explorer 6 (and higher). For details on 
connecting to it, see the 

.

Do the following things regularly to make the GPON Device more secure and to manage the GPON 
Device more effectively.

• Change the password. Use a password that’s not easy to guess and that consists of different 

types of characters, such as numbers and letters.

• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). Restoring an earlier 

working configuration may be useful if the device becomes unstable or even crashes. If you 
forget your password, you will have to reset the GPON Device to its factory default settings. If 
you backed up an earlier configuration file, you would not have to totally re-configure the GPON 
Device. You could simply restore your last configuration.

Here are some example uses for which the GPON Device is well suited.
