This raised the fasted speedof data transfer with a modem from 33.6Kbps(kilobits persecond) to 56Kbps. With this specification, modemtechnology has reached the technological limit fortransferring data over plain old telephone lines.In 2000, the ITU approved the V.92 standard. Thisspecification does not raise the transfer speed, but onlyadds a few minor features. The "Modem On Hold" featureapplies call waiting to your Internet connection. If atelephone call comes in while you are using your browser,this feature lets you put your Internet connection on holdwhile you answer the call. It works with Caller ID, so youcan identify the caller and decide whether to answer thecall.Each time your modem connects, it has to negotiate aprotocol and speed with the other modem. The beeps andtones you hear when your modem dials is that negotiation.The "Quick Connect" feature makes the modem remember theconnection setting from the last time it connected to thatnumber, and it uses that setting to quickly reconnect.V.90 modems, referred to as "56k modems" cannot actuallycommunicate at 56Kbps. Because of the antiquated design ofthe telephone system, signals with a frequency that highwould interfere with signals on adjacent circuits. Thisphenomenon is called "cross talk". In order to preventcross talk, the Federal Communications Commission (FCC)has set a limit on the power you can send over thetelephone line. A V.90 modem can usually transfer data atonly 44Kbs to 48Kbps.In order for the new V.92 features to work, modems atboth end of the line must be capable of using the V.92protocol. You can usually upgrade your modem to V.92 bydownloading and installing the latest driver from yourmodem manufacturers Web site. Although V.92 does notincrease the maximum download speed, it does increase themaximum upload speed from 33.6Kbps to 48Kbps. Many serviceproviders equipments bandwidth is already stretched tothe limit and they are not interested in upgrading to thenew standard.A service provider has the option to disable the new V.92features. They can set the amount of time a connection canstay on hold. If you answer a call, dont expect yourInternet connection to stay on hold for more than a fewminutes. A service provider may disable Quick Connect inorder to throttle the bandwidth back when his equipment isreaching full utilization.The V.92 standard is associated with the new V.44compression standard. This standard increases thecompression ratio to 6:1 from the 4:1 ratio of the V.42bisstandard. When uncompressed, the data can be passed toyour computers UART (Universal Asynchronous ReceiverTransmitter) at speeds up to 180Kbps. The standard UARThas a maximum speed of only 115.2Kbps.Should you upgrade your modems driver to the new V.92standard? With the V.90 specification, modem technologyhas reached the technological limit for transferring dataover plain old telephone lines. The new V.92 standard onlyadds a few trivial features. Many service providers arenot upgrading to the new standard, or are disabling thenew features. No need to hurry to upgrade your modemsdriver.----------------------------------------------------------Resource Box:Copyright(C)2002 Bucaro TecHelp.
