AT&T is currently retiring TDM copper-based telephony systems across the United States and replacing them with next-generation technology.
The N.C. Department of Information Technology has partnered with AT&T to retire TDM technology used by North Carolina’s public sector customers and to provide options for these customers to migrate to IP-based services.
The NCDIT contract that provides these TDM services will expire on Dec. 31, 2025, and it will not be extended. After contract expiration, the remaining services will be subject to much higher tariff rates.
It is imperative that all state and local government customers that purchased AT&T TDM services through NCDIT’s state legacy voice contract work with AT&T and NCDIT to replace their TDM-based technology.

- Due to the volume of outstanding line dispositions, AT&T has extended the deadline for orders until Aug. 31. If you have not yet done so, please contact your assigned NCDIT communication services analyst or AT&T project team member to assess your current services and needs. Please note that AT&T plans to implement tariff rates for any TDM services still in use after Dec. 31. Learn more about these much-higher costs.
- If you are having difficulty identifying the correct disposition of your lines, additional support and services are available for a fee via NCDIT’s Structured Cabling Contract. For more information about that option or to request assistance, please submit a Structured Cabling Work Order Request via the NCDIT Service Portal.

As your site points of contact work with your assigned NCDIT communication services analyst or AT&T project team member to assess your current services, please remember that accurate identification of alarm lines is vital because if any are accidentally disconnected, restoration activities might not be possible.
