UConn has a campus at Avery Point in Groton. Maybe that is what 1373 is used for by your information? Just a hunch.All Below is Security/Police (They do carry guns)
1369 is UConn Hartford campus
1370 Is Stamford UConn but they use the Stamford system mostly right now (TG 204 Encrypted) but are going to move over to the state system 100% soon
1371 Is Waterbury Uconn but they use the Waterbury system (TG 7)
1372 Is Torrington UConn
1373 Is rumored to be UConn somewhere on the shoreline but it has never come up.
The TG are the same on the old state 800 system and the new state 7/800 system
