DTMF tones. 3-4 digits, followed by a single long DTMF tone. (like a pound symbol)
Over and over about 20 times, then ended.

OTA Reprogramming of the CTCSS/DCS Control pannel ?
Generally tho those are muted - varies by make/mode of the Control Panel

It sounded like some sort of alert. The same four - five digits followed by the long tone.

Well it's this license. CWID

So it's someone leasing the repeater. There is a bunch of voice comms now, nothing easy to ID however, as the signal isn't great here. Sounds like maintenance comms or something similar.

L.P. Protective in Somerville.

This is a fire alarm company The Locution system is the transmitter hooked into water flow alarms. The numbers are coded locations of customer locations. The DTMF is used to test and reset control panels.
