The City of Tonawanda Police Department's non-emergency phone line will experience intermittent interruptions and silence from midnight to 6 a.m. on Dec. 14 and 15.
The interruptions are part of regular maintenance and will not affect the 911 line, according to a police notice.
Capt. Frederic Foels said anyone who has an issue with the phone lines during the outage is encouraged to call 911.
The fiber optic non-emergency phone lines are being upgraded by Spectrum, noted Foels.
