Shelezyaka - the prefix to the phone to remove noise and clicks.
· REAL MODEM UPGRADE TECHNOLOGY · Bring to your attention one more pribambasinu to your modem. In the first issue we have already told you about a signal booster telephone line, and now it's time to tell you about the very fundamentally different lronburg that will allow you to get rid of any noise and clicks on the line, arising due to the induced electricity. Just want to tell you that the author of this text is unknown, but the text was racked from the depths of the Internet. That's all that I (Shaitan / SoK) wanted to say about it. And now give the floor to our unknown author, but first give your attention the scheme of the device. R1 C1 T1 * T2 * O \ / \ / \ / \ / \ / \ / \ / \ / o ATS R2 Modem O / \ / \ / \ / \ / \ / \ / \ / \ o * C2 Entry ~~~~~~~~~~ So we are on the verge of great discoveries. Our eyes make the technological revolution - modems have become so perfect that it is time to improve their telephone lines. Not to think that it is very difficult - you it is now also under strength, so we developed and tested a new device that extends the ability of your phone line. Principle of operation ~~~~~~~~~~~~~~ Transformer T1 is designed for high performance filtration high interference. This allows us to successfully confront the appearance of interference due to operation of electrical appliances and such bad thing as laying parasitic interference radio transmission network in your apartment or office. Plot scheme, collected on the passive elements R1, C1 - R2, C2, is for frequency correction of the input signal. As we know from the course of circuit theory, telephone line is a natural analogue of the so-called long-line, work which at one time studied the Lord Kelvin in the design of the communication line between America and Europe. Long line applies to circuits with distributed parameters and the specified area as the scheme brings the kind of signal to the original. And finally, transfrmator T2 performs important function of the passive amplifier signal. Ergo, we got a cheap and practical a device that improves the line parameters Communication and beneficial effect on the quality of faksmodemnoy communication. Manufacturing & Parts ~~~~~~~~~~~~~~~~~~~~~ Transformer T1 contains 2 independent winding to 7 turns each, and wound on the ferrite ring rigorously symmetrical, ie both windings are wound roughly clockwise. Wire - coating, approximately 0.5 mm in diameter. Resistance R1, R2 - 10 .. 50 ohms, which determined empirically and depends on the length of the line from the PBX to your telephone wall socket, which includes a modem. Capacitors C1, C2 - 0.1 microfarads. Transformer T2 has 2 independent winding turns of each of 30-60, and wound on the ferrite ring rigorously asymmetric, ie windings are wound in different directions. Wire - varnishing approximately 0.5 mm in diameter. Try to place the transformers T1 and T2 away from each other - this improve the overall performance of the apparatus. STE truncated wrote not me! But the thing ..... cool ..... ispytavayu ...... Duc .... less glitches and vaaasche ....;) Collecting! Attempt - it has not yet been torture! ;-)
