You may have noticed a charge on your telephone bill for the Colorado Universal Service
Fund. This charge is required by the Colorado Public Utilities Commission (PUC) to pay
for the Colorado Universal Service fund established by state law.
What is the Colorado Universal Service Fund?
There are two primary purposes of the fund: (1) to make basic voice telephone service affordable in certain high cost areas of Colorado; and (2) to provide funds for grants to build broadband networks in unserved areas of Colorado. The PUC provides Universal Service Fund payments for basic voice telephone service to telephone companies that serve areas with high costs and meet other PUC requirements for the funding. Grants for building broadband networks are determined and overseen by the Colorado Broadband Deployment Board. Payments to telecom providers for basic voice telephone service in high cost areas are overseen by the PUC.
What services is this charge applied to and who pays it?
This charge is assessed as a percentage of your in-state telecommunications services for
local, wireless, paging, in-state long distance, and optional services. The charge is not
applied to interstate services. All telecommunications customers in Colorado pay this
monthly charge.
What is the monthly charge?
The monthly charge is currently set at 2.6 percent, which was effective April 1, 2013.
The PUC may adjust the charge over time depending on how much money is needed for
the fund and to make sure that customers do not pay more than is necessary.
Who do I call if I have questions about this charge?
For more information, contact your telecommunications provider.

CO DOC Inmate Communication Services by GTL

In the push to reduce the recidivism rate, correctional facilities are moving away from a traditional layout to one that is designed for inclusiveness and keeping inmates engaged with outside society. Studies have shown that maintaining a support structure is a key component to keeping inmates on the right path to successful reintegration into society after release. In Australia, a new maximum security prison opened this year that includes no cells. Instead, inmates are housed in dormitory-style accommodations with 25 inmates in 16 ‘pods’ that offer more access to education, entertainment, and communication with friends and families. This novel move seeks to enhance inmates’ daily lives by making these services more accessible and improve re-integration into society. Inmates have access to technology that connects them with friends and family members, news, books, movies, education, games, and more. They are required to work for up to five hours during the day and pursue education and other programs in the remaining time. This progressive approach aligns with GTL’s vision of technology and education being available to every inmate. “GTL has the technology portfolio to enable correctional facilities to execute their strategies,” said Gad Tobaly, President, GTL International. “Whether those strategies are similar to the open-plan jail approach or focus on a more traditional environment, we offer the innovations to help facilities become safer and more secure while providing inmates with access to programs that improve their lives during and after incarceration.” GTL creates new technologies and advocates for tablets, education, and other programs to help reduce recidivism rates. “These new facilities highlight the need for technology in corrections,” said Eric Gonzalez, Executive Director, Technology and Implementation Services. “Today’s inmates are digital natives, having grown up in the age of computers, cell phones, tablets, and more. It is only logical that providing them with technology and programs to learn and better themselves through those access points is the direction that corrections is taking.” As part of GTL’s ongoing mission to keep our offerings in line with global corrections trends, the company will once again be a sponsor at the International Corrections & Prisons Association (ICPA) Annual Conference. This year’s conference is being held at the Montreal Marriott Chateau Champlain in Montreal, Canada. The conference theme of “Beyond Prisons: The Way Forward” will draw discussion on the underpinning philosophies, strategic direction, policies, and practices being instituted across the globe. More than 500 delegates from over 70 countries attend this prestigious conference. GTL and two collaborating organizations will present on two topics that relate to the use of technology in aiding the corrections and criminal justice systems. “Transforming the Inmate Environment: How and Why Facilities are Implementing Tablet Programs” will discuss how technology is used to humanize correctional efforts and will take place on Tuesday, October 23rd at 11:00 a.m. in Maisonneuve A Room. “Virtual-Enabled Justice: Delivering Swifter Outcomes and Improved Victim and Witness Experience” will discuss the use of technology to create ‘virtual courts’ that fuel efficiency, safety, and security, and will take place on Tuesday, October 23rd at 3:30 p.m. in Maisonneuve A Room.
