PRODUCT INTRODUCTION 
1.1  
General Description 
The ONT-BBPSU (Optical Network Terminal Uninterruptable Battery Backup Power Supply Unit) 
is designed to be mounted inside a customer premises and provides power to the ONT.  The 
Optical Network Terminal (ONT) is an equipment box typically installed on the outside of your 
home, where the fiber network terminates and the inside wiring for your home originates.  The 
BBPSU supports wireline voice communications services by converting 120/230Vac to 12Vdc.  
AT&T supplies the initial backup battery for the BBPSU to the first resident of the premises 
where AT&T services are installed.  All subsequent backup batteries are the responsibility of the 
customer at the premises.  When equipped with a new, fully charged battery, the BBPSU 
provides four to eight hours of backup battery power.  Actual results will vary, depending, 
among other things, on battery age, usage patterns, and environmental conditions.  To 
conserve battery backup power for emergency calls, you should not use Internet services during 
a power outage.

Components 
The ATT3612V3S unit consists of a dedicated 120/230Vac to 12Vdc power supply with Backup 
Battery and dedicated support cables.  
The ATT3612V3S unit houses a dedicated battery charger to maintain a 12Vdc, 7.2Ah sealed 
lead-acid 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.
