I have two POTS lines into my home. One is measured service
residential and the other is for my business. The only difference between the two as far as I can tell is that the telephone company gets to charge me four times as much for the business line. This is going to sound really strange. Every so often when I'm on the phone (either line) with someone I hear these strange noises. The only way to describe them is: "BOING, BOING, BOING, etc. The onset of these noise cannot be associated with anything in particular. They seem to happen randomly and their duration, as well as their amplitude is random as well. Sometimes they are almost deafening and at other times they are soft. The interesting thing is that only I can hear them. The person on the other end cannot. The telephone company hasn't got a clue as to what could be going on and have asked me to try to log these events. So far, as near as I can tell I don't think I've heard it on local calls but rather on calls to cell phones, 1-800 numbers and long distance calls. I've called them a few times about this and I figure by now they're starting to think that I'm nuts. Perhaps whoever reads this will concur, however I know that this is happening. Does anyone have any ideas as to what this could be? Thanks, Lenny |

You got a bong, followed by repetitive decaying bongs. I recall that sound comes from lack of echo cancellation in the boost amplifier circuitry. Boost amplifier amplification goes either towards you or away from you so when one side acts up only one person hears it. They have a lot of anti-echo in them, but sometimes.... Definitely COMPLAIN.If you can record, do so. Your telephone carrier has a monopoly *AND* a charter to supply you certain quality of telco line, when it does not, the Utilities Commission should get involved. If the sound prevents you from successfully completely a call, they have failed in supplying you with 'minimal' service. Until they repair, ask for reduction in service cost. Second, but not as likely, is a cable bundle that has 'failed' and lines are crossing and disrupting each other. We had that problem once and after any call so disrupted, I called to complain, giving time, length of disruption, and type of disruption. Only took three months, but they finally found the problem: one of those huge buried cable bundles with multitude of telephone pairs had gone wanky. Random noise, and worse, randomly lines would cross to other lines. They pulled a new bundle - a major operation, and voila! clean phone service again. There is a third potential, but that is most likely heard at both ends - your phone is tapped. illegally tapped probably. If you check with phone company they'll deny, assuring you there is no tap on your line and no way to tap your line without their knowledge. Yeah, right. ....still shuddering from personal experience on that one. |

I worked at Bell Labs for 44 years in local switching area, so not totally uninformed. We have had a problem with a buried cable in our neighborhood which was installed in the 1960s that has had water penetration for 7 years. We lose our dial tone when it rains. After having technicians switch our line back and forth between a staticy line and the no dial tone line for years, we were told by a tech that AT&T won't replace the line and Uverse is more than a year away. We haven't had a dial tone in over 2 weeks so we are switching to cable internet and phone. I didn't think of the Utility commission but I will report them now. It is really sad what AT&T has become.

I've had my share of them. But that is not what I'm experiencing though. My lines off hook without dial tone are clean. Lenny |

Thanks, Lenny Just reread your original posting. ASK each time you hear if the other person is on a landline or cellphone. Cellphones have a distinct delay between microphone pickup and transmission. They are notorious for creating weird echo's. How many times have we heard the convesation 6 or 7 times?! and had to break, and re-establish the connection to even talk? |

How many times have we heard the convesation 6 *or 7 times?! and had to break, and re-establish the connection to even talk?- Hide quoted text - - Show quoted text - VERY GOOD point!! |

The telephone company hasn't got a clue as to what could be going on and have asked me to try to log these events. So far, as near as I can tell I don't think I've heard it on local calls but rather on calls to cell phones, 1-800 numbers and long distance calls. I've called them a few times about this and I figure by now they're starting to think that I'm nuts. Perhaps whoever reads this will concur, however I know that this is happening. Does anyone have any ideas as to what this could be? Thanks, Lenny Had similar experience, but sounded like standing in a cave and hitting the side of a garbage can. You got a bong, followed by repetitive decaying bongs. *I recall that sound comes from lack of echo cancellation in the boost amplifier circuitry. Boost amplifier amplification goes either towards you or away from you so when one side acts up only one person hears it. *They have a lot of anti-echo in them, but sometimes.... Definitely COMPLAIN.If you can record, do so. *Your telephone carrier has a monopoly *AND* a charter to supply you certain quality of telco line, when it does not, the Utilities Commission should get involved. If the sound prevents you from successfully completely a call, they have failed in supplying you with 'minimal' service. *Until they repair, ask for reduction in service cost. Second, but not as likely, is a cable bundle that has 'failed' and lines are crossing and disrupting each other. We had that problem once and after any call so disrupted, I called to complain, giving time, length of disruption, and type of disruption. *Only took three months, but they finally found the problem: one of those huge buried cable bundles with multitude of telephone pairs had gone wanky. Random noise, and worse, randomly lines would cross to other lines. They pulled a new bundle - a major operation, and voila! clean phone service again. There is a third potential, but that is most likely heard at both ends - your phone is tapped. *illegally tapped probably. *If you check with phone company they'll deny, assuring you there is no tap on your line and no way to tap your line without their knowledge. *Yeah, right.. ...still shuddering from personal experience on that one. The CO is 30 miles from my house so yes I'm certain that there are many opportunities along the way to access my line, but you're probably correct in that it's most likely something else. I don't believe anything they tell me either. The phone company is notorious for keeping secrets. *The boost amplifier echo cancellation theory sounds like a more likely scenario. I will suggest that to them. When I was a kid we would go down to the basement of the apartment building in which I lived with a 500 set with clip leads. so I know how easy it is to tap a line.

I got the opportunity to speak to the "tech" at the phone company yesterday. Unlike companies such as Verizon or Southern Bell, this part of the state is serviced by a very small independent telephone company that services just several small towns. It's relatively friendly. They have just one senior tech. We spoke for awhile. I mentioned the boost amplifier theory and asked him how calls are processed in this area. He said that years ago everything went out on "T" lines. Today, in addition to the "main" CO. there is a "sub CO" here in town. The switch is a recent electronic one with enhanced 911. Nothing special happens on calls placed within town, however as soon as the call leaves town it gets converted to fiber and then depending on how it's routed and where, who knows what happens. So short of shot gunning the switch, which he's willing to try if all else fails, due to the extremely sporadic nature of this problem, he said that they really can't do anything about it right now. I can understand this. He has asked me to keep a log of the problem, recording date, time, which line, etc and then perhaps we'll notice a pattern. It would also be handy if I could catch an audio recording at will of this ghost as well. I'll have to work on that one. I could probably hang a cassette recorder with remote recording capability on the line, along with something like a Viking RC1 (I think it is), DTMF operated gate controller. It gives you a relay output when it hears a pre programmed DTMF code. I would need one for each line though, unless you guys have a better idea. Lenny |

Do you have a REALLY old phone exchange for your area? This noise is typical of Western Electric (AT&T) crossbar switches, which I haven't heard in decades. But, when switching other lines they did produce a VERY loud and distinctive bell-like ringing when the contacts had become dirty. They had to clean them periodically, like every year or so to eliminate this noise. The interesting thing is that only I can hear them. Hmm, that's a little odd, I think the crossbar bongs would be heard on both ends. The fact you get it on both lines (do you use the same phone for both lines?) seems to indicate it may not be a phone co. problem, but in your house wiring or whatever. Jon |
