Definition and meaning of V.42

V.42 is an International Telephone and Telegraph Consultative Committee (CCITT) V-Collection wellknown that regulates errors-detection for high-speed Modems. V.42 permits Laptop Modems to work with both Digital and Analog telephone traces. It’s an blunders-correcting process for facts Communications System (DCE) that uses an Asynchronous-to-Synchronous conversion.

What Does V.42 Mean?

V.42 lets in Receivers to request the retransmission of lost facts Packets, although it does not offer a assure approximately how a whole lot time it'll take to supply the mistake-loose Records to the receiving aspect. V.42 is normally included in dial-up modems and even includes an high-level Data Hyperlink control-based Protocol known as Link Access Procedure for Modems.

The V.42 protocol consists of a few nicely-described traits:

• A non-error-correcting mode with V-series DCE, such as asynchronous-to-synchronous conversion according to ITU Telecommunications Standardization Sector hints
• Permits errors detection the usage of a Cyclic Redundancy Check. Error Correction is finished the use of the automated retransmission of inFormation.
• Enables Synchronous Transmission via start-prEvent facts conversion and an iNitial handshake in start-prevent format that reduce DTE disruption
