WASHINGTON, Aug 26 (Reuters) - AT&T ( T ) has agreed to

pay $950,000 to resolve a Federal Communications Commission

investigation into an August 2023 outage of 911 calls in four

states, the agency said Monday.

The outage, which occurred during testing of portions of

AT&T's ( T ) 911 network, impacted calls in parts of Illinois, Kansas,

Texas, and Wisconsin.

AT&T ( T ) has agreed as part of the settlement to implement a

three-year compliance plan aimed at ensuring future compliance

with the FCC's 911 and outage notification rules. The 911 outage

lasted for 1 hour and 14 minutes, resulting in over 400 failed

911 calls, the FCC said.
