You are responsible for calling 811 prior to any construction which requires digging, in order to have underground lines located. Fencing, planting trees, watershed projects, and tilling operations are a few examples of when a call to 811 should be made. We have two-business days to respond to a request to mark our lines (excludes weekends and holidays). Call early to ensure that you do not cut unmarked lines and incur additional charges. Know what’s below – Call 811 before you dig.

Backup Power for Voice Telephone Services During Power Outages:  Many of today’s advanced home phone services, including service provided over fiber or over fixed wireless, require backup battery power to continue functioning during an outage. For customers who do not receive voice service over a copper line, a battery backup solution is needed to avoid a disruption of voice service during an outage and to maintain the ability to connect to 911 emergency services.


What Your Battery Can – and Can’t – Do for You:  Colorado Valley offers an optional backup battery solution for fiber and fixed wireless customers to allow you to continue to use your voice service during a power outage, or you may choose to buy your own battery backup from a third party seller. Without a backup battery or alternate backup source such as a generator, fiber and fixed wireless customers will not be able to make any calls during an outage, including emergency calls to 911. The only way to maintain the ability to use your telephone is by using some form of backup power.

Our 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 residential voice telephone backup battery. It is important to note the battery backup does not provide power to a cordless phone. To ensure uninterrupted service during a power outage connect a standard corded phone directly to the modem.


Expected Backup Power Duration:  Backup batteries provided by Colorado Valley are expected to last at least 8 hours on standby power. Talk time will vary based on proper usage and storage conditions. If you feel that is not enough time, you may extend your standby power by purchasing a 24 hour battery or additional 8 hour batteries.


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. These batteries are rechargeable. They will not last forever and should be replaced every 1 to 2 years. 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.


Purchase and Replacement Options:  If you wish to purchase battery backup directly through Colorado Valley, please call 800-242-5911 or email for more information. Battery backup options provided are based on the type of service that you have.
