Control Method for DSI / DS1E Signal and ATM Cell Bus Connection Device in Demand Dense Optical Subscriber Transmitter

摘要

The present invention relates to a control method for a DS1 / DS1E signal and an ATM cell bus connection device in a demand dense optical subscriber transmission device, the method comprising: initializing and reinitializing the DS1 / DS1E signal and ATM cell bus connection device; Register an interrupt vector and an interrupt service routine (ISR), create a communication queue, perform FM processing to perform LOS and AIS declaration / release operations on DS1E signals, and process PMs to generate performance monitoring items. CM process that manages and maintains PVC information and loopback designation / release information, OAM processing that performs PM function, connection normality check function, and loopback function by MCCU command, and related to transmission of IPC data. IPC transmission processing, ISR processing that generates an event in the corresponding processing when an interrupt occurs, IPC reception processing related to IPC message reception, test IPC cell transmission, Registering the menu processing to perform the PVC setting, loopback setting function in the memory, and is performed.
