Total Access 300 GigE SFU ONT with RF Overlay Installation and Maintenance Guide
• μ‐law or a‐law voice coding
• 30 mA loop current
• Integrated GR‐909 testing

RF Interface

The ONT includes an analog video transmitter that provides a CATV interface over a standard
F‐Type connector. The RF interface capabilities are listed below:
• Frequency Range of 54 ‐ 870 MHz
• 136 channels
• Support for both Analog and Digital CATV channels

UPS Power Supply

The power feed is 12 VDC. The ONT utilizes an uninterruptible power supply (UPS). A UPS
(see Figure 5) is a battery backup system designed to continue providing power when the
primary power source is lost. When the UPS senses a loss of power from the primary source,
the backup battery is activated to provide power for a short period of time.
Power is supplied to the ONT by an UPS local power source with battery backup that utilizes
the AC power at the customer premises. The unit powers the ONT and functions as a battery
backup supplying continuous 12 VDC. It contains one sealed, lead‐acid battery for power
backup.
If the battery is disconnected, the ONT is not protected from power outages, and will send a
"Battery Missing" alarm to the OLT.
Install the UPS per the specifications recommended by the manufacturer.
