The ATM, which is expected to give us broadband capabilities, have got many opportunities. It gives us high bandwidth, the users of the bandwidth could be quite flexible, it provides us with variable betreat and service integration. The use of cellulars priority can give us the availability of the ABR availability of service, an unspecified betreat service. The multi-point distribution in the network is possible with ATM and the multimedia, multiplexing and multiple connection becomes quite flexible with the ATM. However, ATM also has certain limitations, like the cells might be lost, the delay might be jetting in the cell transmission and reception, packetization delay would be there and the parameter control, that is the peak or the average rate has to be appropriately taken care of.
