Important Customer Information Regarding your AT&T Voice and Internet Service

Please retain for you r records

Required Optical Network Terminal Battery Backup Power

Your AT&T voice and Internet services require electrical power from your home to operate. Electricity
from your home powers the Optical Network Terminal (ONT), an equipment box where AT&T’s fiber
network terminates and inside wiring for your home originates. AT&T provides a Power Supply Unit
(PSU) for the ONT, which can be placed within 100 feet of the ONT and is installed inside your home or
garage. AT&T supplies an initial backup battery in the PSU for 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.

If a power outage occurs, you will not be able to make or receive calls, including 911 calls, unless you
have battery backup power for the ONT. During a power outage, if you wish to conserve battery power
for making and receiving necessary calls, you should avoid making unnecessary calls and not use AT&T
Internet service. (If you have AT&T Internet or U-verse Voice service(s), there are additional
requirements for battery backup power for the Residential Gateway—see Note #1 below).

Optical Network Terminal Backup Battery Replacement
You are responsible for monitoring the backup battery and will need to replace it when necessary. AT&T
shall have no liability for the failure of your service to function during a power outage, including failure due
to the absence or insufficiency of battery backup power. For ONT battery replacement and recycling

please contact GS Battery (USA) Inc. at 1.800.472.2879 or

www.gsbattery.com. Be sure to have the

battery model number available, which is PX12072-HG. The battery number is also located on the label
on the side of the battery. AT&T does not supply replacement batteries.

You may also be able to purchase replacement batteries through other suppliers (e.g., Batteries Plus,
Radio Shack and via the Internet from Amazon or Sears). Batteries must be of the 12-volt - 7.2 amp hour
variety with F2 Faston connectors and a size not to exceed 6.05” Length x 2.6” Depth x 4.05” Height.
Locations where batteries are available are subject to change.

Portable generators with 120-volt outlets and extension cords will power the PSU in the event of extended
power outages. See manufacturer details for operating and safety procedures when using a portable
generator. Other 120-volt PSU backup solutions may be available at certain home and electronics stores
(e.g., Uninterruptible Power Sources (UPSs) and Duracell

®

Standby Power Plugs).

Determine the Power Supply Unit (PSU) type

On the front of the PSU is a label that shows the Serial Number, designated by S/N. If the S/N starts with
DAE this is a Delta PSU. If the S/N starts with CYB this is a CyberPower PSU. See also the images
below.

Delta PSU CyberPo wer PSU

How to tell when to replace your battery
Delta PSU:

There are status lights on the front right of the Delta PSU. Refer to the Replace Battery and Missing
Battery status lights. The Replace Battery status light will be red if the battery needs to be replaced. An
audible alarm will also sound, with one beep every fifteen minutes, when the battery needs to be
replaced. When the power supply begins using battery power, it will beep once and then remain silent.
While running on battery power, if the battery begins to run low, the alarm will beep four times per minute.

ATTACHMENT A

ATTACHMENT A - Page 1 of 33

The alarm can be silenced for 24 hours by pushing the blue button on the front of the power supply. The
Missing Battery status light will be green if no battery is connected to the power supply.

For more information see the owner’s manual: att.com/batterybackup.

CyberPower PSU:

There are status lights on the front right of the CyberPower PSU. Refer to the Replace Battery and
Missing Battery status lights. The Replace Battery status light will be red if the battery needs to be
replaced. An audible alarm will also sound, with two beeps every three minutes when the battery needs
to be replaced. While running on battery power, if the battery begins to run low, the alarm will beep four
times every two minutes. The alarm can be silenced for 24 hours by pushing and holding the blue button
on the front of the power supply for three seconds. The Missing Battery status light will be red if no
battery is connected to the power supply.

For more information see the owner’s manual: att.com/batterybackup.

Replacing the Battery

Open the door, carefully pull the battery off the shelf and remove the black and red wires. Connect the
black (-) and red (+) wires onto the new battery noting the proper battery polarity. Slide the new battery
onto the shelf and secure. Close the door.

NOTE #1: If you have AT&T U-verse services (voice, high speed Internet, and/or TV), you must also have
battery backup power for the Residential Gateway for your AT&T U-verse services to function during a
power outage. For Residential Gateway battery-replacement and recycling information contact BELKIN
at 866-539-5791 or www.belkin.com/gatewaybattery. For more information, please refer to your Feature
Guide and your Belkin® | Residential Gateway Battery Backup User Manual.

NOTE #2: If you have Internet Service, you must provide battery backup power for your computer, if you
would like to have access to the Internet during a power outage. For example, your computer could be
plugged into an Uninterruptible Power Source (UPS), available at certain home and electronics stores.

NOTE #3: If you have a monitored home alarm that uses AT&T voice or Internet service as the
communications pathway, your monitored home alarm will not function during a power outage without
battery backup power for your AT&T voice or Internet service, as applicable. (AT&T voice service requires
ONT battery backup power, and AT&T U-verse services, including AT&T U-verse voice service, requires
both ONT and Residential Gateway battery backup power to function during a power outage).

NOTE #4: The ONT battery backup will not power cordless phones, home alarm panels, or other
equipment, such as telecommunications devices used to assist customers with disabilities, that are
connected to the telephone line and require electricity from the customer’s premises.

NOTE #5: A new, fully charged ONT backup battery will provide four to eight hours of backup power.
Actual results will vary, depending, among other things, on battery age, usage patterns, and
environmental conditions, including temperature extremes and fluctuations. To conserve battery backup
power for emergency calls, you should not use Internet services, U-verse TV or make unnecessary voice
calls during a power outage.

If you have any a dditional questions, please call 1.800.ATT.2020 or 1.800.288.2020.

U-verse Voice Back-up Power for RG & ONT

Historically, telephone service has been powered by electrical
power within the telephone network. Your AT&T U-verse Voice
service, including 911 dialing, requires electrical power and will not
function during a power outage without battery backup power at
your premises; therefore, you must at all times maintain a working
backup battery for both your Residential Gateway (RG) and Optical
Network Terminal (ONT) (if applicable, please see below) at your
premises. You are solely responsible for monitoring the RG and
ONT (if applicable) backup batteries to determine when they
require replacement, and replacing and recycling used batteries in
accordance with manufacturer or vendor directions. You are solely
responsible for obtaining and maintaining backup batteries or
other sources of power for any cordless phones you use with your
U-verse Voice Service. AT&T shall have no liability for the failure
of your service to function during a power outage, including failure
due to the absence or insufficiency of battery backup power.

In the event of a power outage, you should ensure you have one
corded single-line, touchtone phone connected directly to the
AT&T U-verse Residential Gateway or your in-home wiring and the
RG Battery Backup connected to the RG. (Rotary/pulse phones do
not work with AT&T U-verse Voice service.) If you connect more
than one corded phone, it will use more power; if you connect
a cordless phone, it will not function without a separate battery
backup, and not all cordless phones are so equipped. If you have
a monitored home alarm that uses AT&T voice or Internet service
as the communications pathway, your monitored home alarm will
not function during a power outage without battery backup power
for your AT&T voice or Internet service, as applicable. If you have a
monitored home alarm, you should never plug a multi-line phone
directly into the Residential Gateway—it could interfere with the
alarm signals. You should not connect the RG battery backup to
any device other than the AT&T U-verse Residential Gateway or
use it with any service other than your AT&T U-verse Voice service,
and you should always have an alternative means of dialing 911,
such as via a cellular telephone. The RG battery backup will not
power cordless phones, home alarm panels, or other equipment,
such as telecommunications devices used to assist customers with
disabilities, that are connected to the telephone line and require
electricity from the customer’s premises.

Broadband Network: AT&T U-Verse Voice is provided to you
over a broadband (Internet Protocol or “IP”) network. If there is a
broadband network outage, your AT&T U-verse Voice service will
not function and you will not be able to make 911 calls with this
service. AT&T recommends that you always have an alternative
means of accessing 911 during a broadband outage, such as via
a cellular phone.

ATTACHMENT A

ATTACHMENT A - Page 22 of 33

The OPTICAL NETWORK TERMINAL (ONT) is a box typically
located on the side of your house or in your garage, where
AT&T’s fiber network terminates. Please refer to the pictures
below to determine whether you have an ONT. The ONT also
requires electrical power from your home to operate, which you
are responsible for providing. AT&T installs an initial power supply
box for the ONT when the first resident at a premise orders AT&T
services. The ONT power supply box converts the AC power in
your home to the DC power required by the ONT.

The RESIDENTIAL GATEWAY (RG) is located inside your house
and uses electrical power to deliver all your U-verse services. The
battery backup) for the RG must be installed inside your house
near the RG, and be easily accessible. The RG battery backup
supplies power for your AT&T U-verse Voice service; it does not
supply power for cordless phones (and it does not supply power
for your network interface device or ONT, typically located on
the outside of your home, which may also require battery-backup
power for your AT&T U-verse Voice service to function).

If you have AT&T U-verse services (voice, high speed Internet, and/
or TV), you must also have battery backup power for the Residential
Gateway for your AT&T U-verse services to function during a power
outage. AT&T will not provide support for, or be responsible for,
ongoing maintenance or management of equipment, including the
initial RG battery backup unit or the initial ONT backup battery (if
required) provided to AT&T U-verse Voice customers. If you have
Internet Service, you must provide battery backup power for your
computer, if you would like to have access to the Internet during a
power outage. For example, your computer could be plugged into
an Uninterruptible Power Source (UPS), available at certain home
and electronics stores.

During a power outage, to conserve battery power for necessary
AT&T U-verse Voice calls, DO NOT use any U-verse service other
than AT&T U-verse Voice during the power outage. You should
avoid making unnecessary calls and not use AT&T Internet service.
AT&T recommends that you use a corded phone with AT&T U-verse
Voice during a power outage. (Cordless phones require electrical
power to work and may not be equipped with backup batteries).
AT&T also recommends that you always have an alternative
means of accessing 911 during a power outage, such as a cellular
phone.

Portable generators with 120-volt outlets and extension cords will
power the RG Battery Backup in the event of extended power
outages. See manufacturer details for operating and safety
procedures when using a portable generator. Other 120-volt PSU
backup solutions may be available at certain home and electronics
stores (e.g., Uninterruptible Power Sources (UPSs) and Duracell®
Standby Power Plugs).

Additional Limitations: Please note that AT&T U-verse Voice will
work only in your home. You will not be able to make any calls,
including 911 calls, from any other location, even if you move the
Residential Gateway (RG) or an external Telephone Adapter (TA) to
the new location.

If you have an RG inside your premises, you may also have an
Optical Network Terminal (“ONT”), which is a box typically located
on the side of your house or in your garage, where AT&T’s fiber
network terminates. All of the following information only applies if
you have an ONT. Please refer to the pictures below to determine
whether you have an ONT.

OPTICAL NETWORK TERMINAL (ONT) –

Your AT&T voice and Internet services require electrical power
from your home to operate. Electricity from your home powers
the Optical Network Terminal (ONT), an equipment box where
AT&T’s fiber network terminates and inside wiring for your home
originates. AT&T provides a Power Supply Unit (PSU) for the ONT,

ATTACHMENT A

ATTACHMENT A - Page 25 of 33

which can be placed within 100 feet of the ONT and is installed
inside your home or garage. AT&T supplies an initial backup
battery in the PSU for 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. (If you are not
the first resident, you will not have an initial backup battery from
AT&T; therefore, you should check the PSU for the presence and
status of a backup battery and place/replace if necessary).

If a power outage occurs, you will not be able to make or receive
calls, including 911 calls, unless you have battery backup power for
the ONT. During a power outage, if you wish to conserve battery
power for making and receiving necessary calls, you should avoid
making unnecessary calls and not use AT&T Internet service. To
conserve battery backup power for emergency calls, you should
not use Internet services, U-verse TV or make unnecessary voice
calls during a power outage.

The ONT battery backup will not power cordless phones, home
alarm panels, or other equipment, such as telecommunications
devices used to assist customers with disabilities, that are
connected to the telephone line and require electricity from the
customer’s premises.

Your AT&T U-verse Voice service iPSU requires a backup battery
to maintain your AT&T U-verse Voice service in the event of a
short disruption to your electric power. During a power outage,
to conserve battery power for necessary AT&T U-verse Voice calls,
DO NOT use any U-verse service other than AT&T U-verse Voice
during the power outage. You should avoid making unnecessary
calls and not use AT&T Internet service. AT&T recommends that
you use a corded phone with AT&T U-verse Voice during a power
outage. If you have other AT&T U-verse services (high speed
Internet, and/or TV), you must provide battery backup power for
your inside unit for your AT&T U-verse services to function during
a power outage as well as power for your terminal devices. If you

U-verse Voice Back-up Power for RG, ONT & iNID

Historically, telephone service has been powered by electrical power within the telephone network. Your

AT&T U-verse Voice service, including 911 dialing, requires electrical power and will not function during a

power outage without battery backup power at your premises; therefore, you must at all times maintain a

working backup battery for both your Residential Gateway (RG), Optical Network Terminal (ONT) (if

applicable, please see below) and Intelligent Network Interface Device (iNID) at your premises. You are

solely responsible for monitoring the RG, ONT (if applicable) and iNID backup batteries to determine when

they require replacement, and replacing and recycling used batteries in accordance with manufacturer or

vendor directions. You are solely responsible for obtaining and maintaining backup batteries or other sources

of power for any cordless phones you use with your U-verse Voice Service. AT&T shall have no liability for

the failure of your service to function during a power outage, including failure due to the absence or

insufficiency of battery backup power.

In the event of a power outage, you should ensure you have one corded single-line, touchtone phone

connected directly to the AT&T

U-verse Residential Gateway or your in-home wiring and the RG Battery Backup connected to the RG.

(Rotary/pulse phones do not work with AT&T U-verse Voice service.) If you connect more than one corded

phone, it will use more power; if you connect a cordless phone, it will not function without a separate

battery backup, and not all cordless phones are so equipped. You should not connect the iNID backup

battery to any device other than the AT&T U-verse iNID or use it with any service other than your AT&T U-

verse Voice service, and you should always have an alternative means of dialing 911, such as via a cellular

telephone. If you have a monitored home alarm that uses AT&T voice or Internet service as the

communications pathway, your monitored home alarm will not function during a power outage without

battery backup power for your AT&T voice or Internet service, as applicable. If you have a monitored home

alarm, you should never plug a multi-line phone directly into the Residential Gateway—it could interfere with

the alarm signals. You should not connect the RG battery backup to any device other than the AT&T U-verse

Residential Gateway or use it with any service other than your AT&T

U-verse Voice service, and you should always have an alternative means of dialing 911, such as via a

cellular telephone. The RG or iNID battery backup will not power cordless phones, home alarm panels, or

other equipment, such as telecommunications devices used to assist customers with disabilities, that are

connected to the telephone line and require electricity from the customer's premises.

ATTACHMENT B

ATTACHMENT B - Page 6 of 19

Broadband Network: AT&T U-Verse Voice is provided to you over a broadband (Internet Protocol or "IP")

network. If there is a broadband network outage, your AT&T U-verse Voice service will not function and you

will not be able to make 911 calls with this service. AT&T recommends that you always have an alternative

means of accessing 911 during a broadband outage, such as via a cellular phone.

The ONT is a box typically located on the side of your house or in your garage, where AT&T's fiber network

terminates. Please refer to the pictures below to determine whether you have an ONT. The ONT also

requires electrical power from your home to operate, which you are responsible for providing. AT&T installs

an initial power supply box for the ONT when the first resident at a premise orders AT&T services. The ONT

power supply box converts the AC power in your home to the DC power required by the ONT.

AT&T U-verse Battery Backup

AT&T U-verse Voice, like other Voice over Internet Protocol ("Voice over IP" or "VoIP") services, requires

electrical power at your home to operate. Depending on your service address, your AT&T U-verse Voice

service will include either a Residential Gateway Battery Backup Unit ("BBU") or an iNID Power Supply Unit

("iPSU").

Residential Gateway with Battery Backup

The RESIDENTIAL GATEWAY (RG) is located inside your house and uses electrical power to deliver all

your U-verse services. The battery backup for the RG must be installed inside your house near the RG, and

be easily accessible. The RG battery backup supplies power for your AT&T U-verse Voice service; it does not

supply power for cordless phones (and it does not supply power for your network interface device or ONT,

typically located on the outside of your home, which may also require battery backup power for your AT&T

U-verse Voice service to function).

If you have AT&T U-verse services (voice, high-speed Internet, and/or TV), you must also have battery

backup power for the Residential Gateway for your AT&T U-verse services to function during a power

outage. AT&T will not provide support for, or be responsible for, ongoing maintenance or management of

equipment, including the initial RG battery backup unit or the initial ONT backup battery provided to AT&T

U-verse Voice customers. If you have Internet Service, you must provide battery backup power for your

computer, if you would like to have access to the Internet during a power outage. For example, your

computer could be plugged into an Uninterruptible Power Source (UPS), available at certain home and

electronics stores.

During a power outage, to conserve battery power for necessary AT&T U-verse Voice calls, DO NOT use any

U-verse service other than AT&T U-verse Voice during the power outage. You should avoid making

unnecessary calls and not use AT&T Internet service. AT&T recommends that you use a corded phone with

AT&T U-verse Voice during a power outage. (Cordless phones require electrical power to work and may not

be equipped with backup batteries). AT&T also recommends that you always have an alternative means of

accessing 911 during a power outage, such as a cellular phone.

Portable generators with 120-volt outlets and extension cords will power the RG Battery Backup in the event

of extended power outages. See manufacturer details for operating and safety procedures when using a

portable generator. Other 120-volt PSU backup solutions may be available at certain home and electronics

stores (e.g., Uninterruptible Power Sources (UPSs) and Duracell® Standby Power Plugs).

iNID with Battery Backup

INTELLIGENT NETWORK INTERFACE DEVICE (iNID) includes three components: a unit typically located

on the outside of your premises or in your garage where AT&T's network terminates (the outside unit); a

home networking hub which provides wireless networking capability and is located inside your premises

(the inside unit); and, a power supply unit typically located in a sheltered area either inside your premises

or in an attached structure – garage, closet or basement (iPSU). The iPSU includes a backup battery and

usually will be located near where power comes into your home. The iPSU must be located within 100 feet of

where AT&T's network terminates. If the iPSU is located in an area that you do not use regularly, you should

check the status of the iPSU periodically to ensure that you receive any visual or audible warnings regarding

the condition of the iPSU and battery backup. Portable generators with 120-volt outlets and extension cords

will power the iPSU in the event of extended power outages. See manufacturer details for operating and

safety procedures when using a portable generator. Other 120-volt PSU backup solutions may be available

at certain home and electronics stores (e.g., Uninterruptible Power Sources (UPSs) and Duracell® Standby

Power Plugs).

Your AT&T U-verse Voice service iPSU requires a backup battery to maintain your AT&T U-verse Voice

service in the event of a short disruption to your electric power. During a power outage, to conserve battery

power for necessary AT&T U-verse Voice calls, DO NOT use any U-verse service other than AT&T U-verse

Voice during the power outage. You should avoid making unnecessary calls and not use AT&T Internet

service. AT&T recommends that you use a corded phone with AT&T U-verse Voice during a power outage. If

you have other AT&T U-verse services (high speed Internet, and/or TV) you must provide battery backup

power for your inside unit for your AT&T U-verse services to function during a power outage, as well as

power for your terminal devices. If you have Internet Service, you must provide battery backup power for

terminates and inside wiring for your home originates. AT&T provides a Power Supply Unit (PSU) for the

ONT, which can be placed within 100 feet of the ONT and is installed inside your home or garage. AT&T

supplies an initial backup battery in the PSU for 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. If you are

not the first resident, you will not have an initial backup battery from AT&T; therefore, you should check the

PSU for the presence and status of a backup battery and place/replace if necessary.

If a power outage occurs, you will not be able to make or receive calls, including 911 calls, unless you have

battery backup power for the ONT. During a power outage, if you wish to conserve battery power for making

and receiving necessary calls, you should avoid making unnecessary calls and not use AT&T Internet

service. To conserve battery backup power for emergency calls, you should not use Internet services, U-

verse TV or make unnecessary voice calls during a power outage.

The ONT battery backup will not power cordless phones, home alarm panels, or other equipment, such as

telecommunications devices used to assist customers with disabilities, that are connected to the telephone

line and require electricity from the customer's premises.

Backup Battery for ONT: You are responsible for monitoring the backup battery and will need to replace it

when necessary. AT&T shall have no liability for the failure of your service to function during a power

outage, including failure due to the absence or insufficiency of battery backup power. For ONT battery

replacement and recycling please contact GS Battery (USA) Inc. at 800-472-2879 or www.gsbattery.com.

Be sure to have the battery model number, which is PX12072-HG, and the warranty date, which is located

on the label on the side of the battery. The battery number is also located on the label on the side of the

battery. AT&T does not supply replacement batteries.

When equipped with a new, fully charged backup battery, the PSU will provide four to eight hours of battery

backup power. Actual results will vary, depending, among other things, on battery age, usage patterns, and

environmental conditions, including temperature extremes and fluctuations.

Batteries must be of the 12 volt - 7.2 Amp hour variety with F2 Faston connectors and a size not to exceed

6.05" Length x 2.6" Depth x 4.05" Height.

Portable generators with 120 volt outlets and extension cords will power the PSU in the event of extended

power outages. See manufacturer details for operating and safety procedures when using a portable

generator. Other 120 volt PSU backup solutions may be available at certain home and electronics stores

(e.g., Uninterruptible Power Sources (UPSs) and Duracell® Standby Power Plugs).

Information regarding where replacement batteries can be purchased is listed below. Locations where

batteries are available are subject to change.

Determine the Power Supply Unit (PSU) type

On the front of Power Supply Unit (PSU) is a label that shows the Serial Number designated by S/N. If the

S/N starts with DAE this is a Delta PSU. If the S/N starts with CYB this is a CyberPower PSU. Two models

that look the same are the APC PowerShield PSUs. To determine the model number, loosen the screws in

the battery compartment located at the bottom left of the PSU, lift the PSU up, and look at the model

number on the back of the unit.

Important Offer Details

AT&T supplies an initial backup battery for the UPS to the first resident of a premises where AT&T services are installed. All

subsequent backup batteries are the responsibility of the customer at the premises.

If you have AT&T U-verse Voice service, you should not use any U-verse services other than AT&T U-verse Voice during a

power outage, to conserve ONT battery backup power for emergency calling. Your AT&T U-verse Voice service, including

911 dialing, will not function during a power outage without both ONT battery backup power and Residential Gateway

battery backup power. AT&T supplies a Residential Gateway Battery Backup unit with an initial backup battery for all new

AT&T U-verse Voice customers. For more information, review Learn More about Residential Gateway with Battery Backup.

Note: if your alarm company installs an IP-based panel that will use AT&T U-verse High Speed Internet as the

communications pathway, you must ensure you have functioning battery backup power for your Residential Gateway (and

your ONT, if you have one) for your high speed Internet service to work with your alarm panel during a power outage.
