ALARM INFORMATION TRANSFER METHOD IN ATM NETWORK AND ATM EXCHANGE AND SYSTEM

摘要

PROBLEM TO BE SOLVED: To suppress the decline of the transmission efficiency of user data due to alarm information cells and to efficiently transmit and receive alarm information to/from an opposing ATM exchange.;SOLUTION: This method is provided with a step for coding the plural pieces of the alarm information, turning the coded value and a bit for indicating the state of an alarm into cells, and transferring them to the opposing ATM exchange; and a step for extracting the coded alarm information from ATM cells received in the opposing ATM exchange, decoding the extracted value; and transferring it to a line side as the corresponding alarm information at the time of transferring the alarm information from the present ATM exchange to the opposing ATM exchange by the ATM cells.;COPYRIGHT: (C)2002,JPO
