Backup Power for Home Phone Services during Power Outages

For many years, your home phone would allow you to stay connected to emergency voice services during a power outage.
However, many of today’s advanced home phone services require backup battery power to continue functioning during an
outage. To avoid a disruption of home voice service during an outage – and to maintain the ability to connect to 911
emergency services – you do have the option to have a backup battery installed at your location. This option does have a
monthly maintenance fee. Over time, these batteries need to be replaced. If you subscribe to this maintenance option, we
will maintain your battery and replace when necessary. This will eliminate having to pay the cost for the battery, in addition
to the charge to have a technician come to your location.

What Your Battery Can – and Can’t – Do for You

Paul Bunyan Communications’ backup batteries for the Network Interface Devices allow you to continue to use your home
voice services during a power outage. Without a backup battery or alternate backup source such as a generator, customers
will not be able to make any calls, including emergency calls to 911. The only way to maintain the ability to use your phone is
by using some form of backup power.
The backup battery does not provide power to any services other than voice. Home security systems, medical
monitoring devices and other equipment will not run on a home phone backup battery.

Purchase and Replacement Options

If you are concerned about being able to contact 911 emergency services during a power outage, a backup battery may be a
good option for you. If you elect not to choose the maintenance options where we provide the battery backup, you do have
the option to purchase a battery. There are multiple options available for purchase. If you elect to purchase your battery, you
would be responsible for maintaining and the costs for the replacement of the battery. In addition, service call charges would
apply. Be sure to purchase the battery model that matches the type of Network Interface Device that you have. The type of
Network Interface Device that you have is a Calix ONT. The type of battery that you need is a B.B Battery model # BP7.2-12.

Expected Backup Power Duration

Backup batteries that we provide as part of the maintenance program are expected to last up to 8 hours on standby power.
The backup battery should give you up to [6 hours] of talk time. If you feel that is not enough time, you may extend your
standby power by taking advantage of our maintenance program for our 24 hour battery option. In addition, these batteries
could be purchased by PBC, or a third party, in lieu of the maintenance program.
You can also purchase a backup battery through many of your local retailers or online. Be sure to purchase the battery model
that matches the type of modem that you have. Please contact our business office for specific equipment information as it
relates to the service at your location.

Instructions for Proper Care and Use of Your Battery

Please follow the more detailed instructions included with your battery for proper use, storage and care of your battery to
ensure that it will function as needed during a power outage. If you do not store your battery correctly, it may shorten its
useful life. Environmental factors such as temperature can shorten your battery’s useful life. We recommend that you store
your battery above [41°F and below 104°F]. These batteries are [not] rechargeable. They will not last forever and should be
replaced every [1 to 2 years], or when your device starts to make a loud beeping sound. That sound means that the battery is
depleted, and must be replaced. See the instructions above for purchase and replacement options. You should also
periodically, as described in the instructions included with your battery, remove and test your battery to verify both the
operation of the backup battery and its condition. If you purchase a battery from Paul Bunyan Communications, the models
that we carry perform a self-test. In addition, the LED will indicate when a battery fails a self-test and needs to be replaced.
