OAM FUNCTION AND SIGNALLING OAM Levels in the B-ISDN #)OAM functions in the network are performed on five OAM hierarchical levels associated with the ATM and physical layers of the protocol reference model. #)The functions result in...

What is ATM? #)ATM(Asynchronous Transfer Mode) is a transfer mode in which information is organized into cells. #)It is asynchronous in the sense that the occurrence of a cell containing information from an individual user is not necessarily...

Adaptive filters are the filters that can change its transfer function corresponding to the error feedback so that it can work on noisy environment.ie these type of filters can distinguish the input and the noise and can able to change its transfer...
