A standard error control system that includes LAPM, as well as MNP 2-4.
end-to-end error correction, runs "on top of" V.32, etc, and adds more than 10% to the effective throughput, even for compressed data
Error-correcting procedures for DCEs using asynchronous-to-synchronous conversion.
CCITT industry standard for modem error correction
An international error correction protocol that uses Link Access Procedure Modem (LAP-M) as the primary protocol, and MNP2-4 as back-up protocols.
A CCITT Recommendation for error correction on modem communications.
a CCITT error-correction protocol. Two modems which both have V.42 can exchange error-correction information between themselves, so that a file could theoretically be transmitted error free, even without using an error-correcting transfer protocol. V.42 incorporates MNP 4, so all V.42 modems can communicate with MNP 4 modems.
LAPM error corrrection (selective ARQ)
an error correction scheme used by many V.32 and V.32bis modems that carries asynchronous data using the LAPM protocol over a synchronous connection.
CCITT standard for modem communications that defines negotiation for LAPM error control. V.42 also includes support for MNP error correction protocol levels 1 - 4.
Error control procedures.
ITU standard protocol for doing error correction.
An error correction standard. V.42bis has data compression too.
ITU-TSS standard for modem error checking using LAP-M protocol. MNP-2, -3, and -4 are alternative protocols included for backward compatibility.
An ITU-T standard for modem communications that defines a two-stage process of detection and negotiation for LAPM error control.
ITU-T standard protocol for error correction using LAPM. See also LAPM.
