2. 2 Verizon Technology FiOS  FiOS (Fiber Optic Service) is Verizon’s fiber optic architecture that delivers a fiber optic connection all the way to the customer’s small business or home  FiOS provides a single connection for telephone, high speed data and video services on the fiber optic  FiOS includes 3 network components at the customer premises  ONT (Optical Network Terminal) which converts the fiber connection to electrical connections, meaning standard telephone service, Ethernet for high speed data and Coax for high speed data and/or video  OPSU (Optical Power Supply Unit) which powers the ONT and charges the battery in the BBU  BBU (Battery Back-Up Unit).  1 non-network element required  Battery

3. 3 Verizon Technology Battery Specification The current Battery used in the Fios Program has the following characteristics: Seal Lead Acid Battery 12 VDC nominal Output (Battery output voltage range is 14.5 to 10.5 VDC depending on charge level, temperature, and capacity) 7.2 aH capacity Dimensions are: 6” x 2.5” x 3.75” No consumer maintenance required

4. 4 Verizon Technology Duration During Outage

5. 5 Verizon Technology Blue Button Operation The BBU includes a manually initiated button (blue button) to provide up to 1 hour of emergency use of operation: Once AC is lost, the battery will support the Fios ONT. After the initial battery support time (approximately 8 hours), the ONT will shut off. If the customer has a need to make or receive phone calls after the ONT has shut down, the customer can depress the BBU emergency use button and will have approximately one hour of bi-directional phone use. Once the reserve power is used up, the ONT will shut down until AC power is restored, until the battery is replaced or supplemented, or another acceptable DC power source is connected (e.g. to the BBU coaxial or other connector.)

6. 6 Verizon Technology Life of battery The battery is expected to last at a minimum of three years Verizon offers a “no questions asked” warranty for the initial turn up of service When a new customer moves into a home or business where FiOS was previously installed the new customer receives a warranty for the remaining term of the first year warranty.

7. 7 Verizon Technology Visual Alarms on BBU The BBU contains the following visual alarms and indicators: Missing battery alarm LED. In the event that the battery is removed, or a cell goes open circuit, the BBU will illuminate the “Replace Battery” LED on the front panel Replace Battery alarm LED. Every 45 to 60 days, the BBU tests the battery. Once the battery has degraded to 70% of its service capacity (5.4 aH), an LED illuminates. This failure does not indicate a hard failure, simply a recommendation for replacement. Operating at 70% or less capacity will still provide back up support, but at a reduced capacity. On battery alarm LED. Indicates that the ONT is being powered from the battery and that the AC power source may not be available. Auxiliary battery LED. An auxiliary battery power supply has been connected to the BBU via the coaxial input connector. System LED. Indicates proper operation of the BBU.

8. 8 Verizon Technology Audible Alarms on BBU  The BBU contains the following audible alarms :  Missing battery audible alarm  Replace Battery audible alarm  Low Battery audible alarm. When the battery reaches 50% of capacity, the audible alarm will indicate the condition  Audible alarms are 85db, “smoke alarm” level

9. 9 Verizon Technology Replacement -- how, where get replacement The 7.2 aH, SLA battery is commonly used in Emergency exit signs and home burglar alarms systems. They are available through: Electrical Supply Houses and several retail locations such as Radio Shack, Lowes and Home Depots also carry these batteries Batteries outside of warranty period are the customer’s responsibility to replace. Verizon also has a battery replacement program where for a reasonable fee a customer can get a replacement battery shipped to the customer with a pre-paid pre-addressed return box to return the spent battery. Returned spent batteries are disposed of in an ecologically acceptable manner.
