I didn't know there were any tape-based units still being made. I've been using
a PhoneMate for almost 20 years, and I like it fine. |

![]() OT answering machines again Group: rec.audio.pro Date: Mon, Jul 12, 2004, 5:27pm (EDT+4) From: =A0) Hi folks, I have to replace an answering machine. tHe all digital ones I hear seem to sound like utter garbage over the phone. How much "Hi-Fi" can you expect on a phone that has a frequency response of 300hz to 3.5khz? It's an answering machne, people accept the quality as long as it's intelligible. Eric |

The prolem with many "digital" machine (including mine) is that the greeting, and the incoming messages sound like Darth Vader's voice. "Luke, I am your father. Do we need milk?" This is compounded by the use of cell phones. Don |

This is compounded by the use of cell phones. I've heard a couple of cases where the digitized message contained a codec artifact that my cell phone codec could not deal with. The message played to that point, then was garbage from there on out. Locally, or from an analog land-line, there was no problem. Once you get compression down to 7200 Hz 2-bits adaptive-whatever-law, if the audio makes a change the math can't deal with, sync is lost forever. |

SUre wish they made the old type with the endless loop cassette and the regular cassette to store the incoming messages. NO folks, not going to put a windows PC and sound card on voicemail duty, looking for a stand alone box. WHo's having good luck with what out there for tape based units still on the market? REmote access would be a plus but not necessary. Audio quality does matter to this old grouch however. I went to a voice mail service through the phone company a couple years ago. Best $5/month I've ever spent. Once it's set up I don't have to fool with it & nobody gets a busy signal. It sounds like the phone sounds AFAIC. YMMV |

Once you get compression down to 7200 Hz 2-bits adaptive-whatever-law, if the audio makes a change the math can't deal with, sync is lost forever. I think this utter crap goes under the fancy name of Linear Predictive Coding, which does SERIOUS compression of a phone audio signal. To call the sound robotic is an insult to talking robots worldwide. Whenever I hear it I start lusting for a +/-6dB 300-3.5k response analog line. If you want a standard Phillips cassette-based answering machine, you have to cruise the thrift stores and yard sales, or if your time is better invested elsewhere, hit ebay. Failing that, what's wrong with using an old PC for an answering machine? Other than it being a collection of largish devices (metal box, 13" monitor, and keyboard and mouse dangling someplace), the power supply fan making noise, and it taking maybe 50 to 100 watts (with monitor off) just waiting for a call, vs. 5 watts for a dead quiet answering machine. |

Absolutely true for the 2.4 kbps Inmarsat stuff we were using around 1990. Pretty true for the vast majority of 10kbps stuff we've been living with over the past decade. Marginally true for the 12kbps stuff we've seen over the past 5 years or so. Not true at all for the newest high bandwidth stuff which will probably become the next generation's "toll quality" benchmark. |

What's your take on the fabled "bandwidth glut" of story and song? Did it never happen, or did it all get used up, or ....? I remember seeing crews digging parallel to I-40 planting maybe five or ten square inches of fiber. Isn't that a lot? Inquiring minds...Thanks, Chris Hornbeck |

It happened--there's so much unlit fiber underground that I think you could remake a few decent sized beaches with it. I remember seeing crews digging parallel to I-40 planting maybe five or ten square inches of fiber. Isn't that a lot? Typical underground builds involve 4-15 ducts which can hold from one to six bundles of up to 288 fibers each. These can be laid with automated rail plows and a minimal crew. How many of us remember that the SPR in Sprint comes from Southern Pacific Railroad? |

How many of us remember that the SPR in Sprint comes from Southern Pacific Railroad? Guess, as an American, I shouldn't be surprised. (But it's still a very cool factoid). Now that I think about it, scary too. Oh, well, what's new? Could you give an ordinary idiot like me some idea of the bandwidth involved? Just expressed as a bits per second kinda thing. Thanks again, Chris Hornbeck |

Currently shipping SONET hardwarewill support up to 160 wavelengths on a single fiber pair, each of which can carry about 10 gbits/sec at OC-192. That's pretty cutting edge stuff but there is a LOT of deployed 40-lambda hardware out there. |

It happened--there's so much unlit fiber underground that I think you could remake a few decent sized beaches with it. There's plenty of fiber in my neighborhood now, though it's all overhead. The cost of entering a building from that overhead fiber is still rather high, and the vast majority of people still don't have fiber at the curb yet. If there's a glut, how come they haven't dropped the price of DSL here, and in fact Verizon recently added a $3 "service charge" over their almost-attractive $30/month charge? The last mile monopoly is still holding strong, especially after the last round of Telecom Act lawsuits where the incumbents (after sufficient lubrication to the wheels of government) succeeded in pushing back much of the competetion encouragements of the Act. How come my Internet access, all things considered, is still cheaper with a second POTS line dedicated to that purpose? Used to be that they were screaming that they didn't have enough phone lines to fill all the orders. They've starved out most of the competitors with a combination of lawsuits and slow-roll beaurocracy. Have cellular phones relived that crunch? (and they're already arguing over spectrum allocation) On the voice side? Definitely. Data is getting there but may get swamped by other disruptive technologies before it becomes a significant player. |

Data is getting there but may get swamped by other disruptive technologies before it becomes a significant player. They're arguing about it now because once it's a done deal, it's very difficult to unravel or get reassigned. It'll be interesting to see what happens when all the analog TV signals are reallocated to data & other areas (who knows what); in theory, this should happen in 2006 when TV stations will be required under current laws to turn their analog frequencies over to the government to be auctioned off, but in reality, there won't be enough consumers with digital TV's yet for this to occur "on time". The FCC recently proposed an 80% coverage threshold - meaning that instead of 2006, the changeover will occur when 80% of the households in the country have digital TV, and instantly it was met with opposition from congresspersons who represent poorer districts, large rural areas, etc. -- Neil Henderson Saqqara Records http://www.saqqararecords.com |
