1 PRODUCT INTRODUCTION
1.1 General Description
The DC UPS (ONT Uninterruptable Power Supply with Battery Back-Up Unit) is designed to be
mounted inside a customer premises. The DC UPS converts 120/230Vac to 12Vdc and provides
four to eight hours of backup battery power for lifeline POTS and Ethernet services in the ONT.
Alarm outputs are available on the DC UPS to monitor the status of the backup battery
(On/Low/Faulty/Missing). The DC UPS indicates its status to the resident with LEDs and audible
alarms and to the outdoor ONT by a signal return connection.
1.2 Components
The DC UPS consists of a dedicated 120V/230ac to 12Vdc power supply with Battery Backup
and dedicated support cables.
The DC UPS houses a dedicated battery charger to maintain a 12Vdc, 7.2Ah lead-acid sealed
battery, battery monitoring and alarm circuitry. It contains four indicator LEDs to provide
operational status at a glance, status audible alarms, and one customer-operation button to
silence the audible alarm for 24 hours.
