Top and Front Panel

For added security, when using coaxial cable for upstream communication, you can press the Standby button (1) to suspend your Internet connection. No data is transmitted or received from the Internet when the Standby light is on. All other front-panel lights turn off until you press the Standby button again except the Tel 1 and Tel 2 LEDs.
