> In an emergency, the lines don't get clogged like cell phone tower Back in landline days I was in a couple emergencies where my phone only gave error tones or recorded messages of being too busy. Even in the ancient circuit switched times one could have easily run into a situation where whatever destination out you were trying to go would have been totally full. This idea POTS would never get clogged is a myth. They could handle a lot more capacity than cell phones at the time, sure, but they did still eventually get flooded. And in one of those times, I couldn't get a POTS call out but I could send an SMS and it would eventually get through.
