Nice graphics on the Telecom 99 page. Surfing more on the Newbridge website, I came up with the following at prodweb.newbridge.com:80/news/stories/ip_atm/index.jhtml "By combining IP, ATM and SONET a service provider, and its customers, can get the maximum benefit from each technology. As they now exist, IP, ATM and SONET each has its own inherent advantages. ATM is more deterministic in that it has more traffic and policy features. It also works very well as a gateway technology and has evolved to meet a T1 access requirement from the days when it needed a DS3 pipe. IP is a ubiquitous protocol that is widely available in homes and offices because it uses standard DSO, time division multiplexing pipe technology. In addition, IP keeps router traffic in a more native element domain. And while IP routing and ATM switching both provide Layer 3 protections through logical restoration, SONET provides physical layer protection by allowing bi-directional line switching in the case of a severe failure, such as a fiber cut." I suspect this was written by a marketing person rather than an engineer. IP does not have anything to do with DSO and TDM. IP is a separate layer which at times, may ride on top of a DS0 line which itself may be transported on a TDM circuit... I know, picky, picky..
