Telephone exchange names - Wikipedia
Ours was ME5-2275.
You just dialed (5- and the four digit number) for a local call in the exchange.
Back then if the firehouse siren went off police and fire personnel could dial a number and it would tell them where a fire/emergency was.
LOL....Usually it was the local dump was on fire....Again....So everyone would show up with .22s for a "rat shoot", then put the fire out.
