Having recently inherited a radio system that has a lot of leased analog audio phone lines, many of which have some kind of trouble, I would like to know some kind of general specs that the phone company is obligated to maintain. It seems hard to find anything on Google, maybe because POTS is thought to be on the way out?
I am looking for figures like
-max permissible attenuation end to end (16 dB is what I have)
-max dB deviation between frequency response
-amount of broadband hiss/60 Hz hum picked up on a quiet line
-anything else you think I should be looking at
The phone company is AT&T/Pacific Bell and the lines are all within about 20 miles although some do run from one CO to another.
Thanks
