The Public Service Commission voted Jan. 15 to approve AT&T Enterprises LLC and Teleport Communications America LLC’s notice to discontinue ALS and Prime digital trunk business services, effective on or after Jan. 30, 2025.

Cameron Walton, presenting on behalf of staff, told commissioners that AT&T filed a notice on Dec. 10, 2024, and has one remaining business customer on the legacy services. Walton said the services were grandfathered in 2015, are not part of AT&T’s Maryland tariffed offerings and are provided pursuant to company service guides. The company provided prior notices to the impacted customer (including communications around Nov. 8, 2024) and is offering additional time to migrate that customer because of account complexity.

Staff recommended approval of the discontinuance, noting AT&T’s compliance with the Code of Maryland Regulations notification process. The commission approved the discontinuance on a unanimous voice vote. The transcript records no intervening public opposition during the meeting.

No further details about the identity of the remaining business customer or migration plan specifics were disclosed in the transcript.
