Considerations for ATM deployment in the telephony network

As the deployment of broadband technology for data gains more ground, the application of asynchronous transfer mode (ATM) in the public switched telephony network (PSTN) begins to be considered. The network providers evaluate business drivers which may lead to the change, and identify the technology issues to be addressed. This paper presents a set of factors which will influence the introduction of ATM in the PSTN and highlights the network architecture and technology aspects to be considered for implementation.
