There were a number of problems with the original implementation using ATM. This caused the introduction of the FDDI network. Dual FDDI networks were created. The second ring is pretty quiet. The diagram should be on the web soon.

ATM Switch Criteria
NEWBRIDGE 36150 is in use. It may not be the best, but was the best in 1992. The Cisco Lightstream is being considered, but there are somethings missing on in it that are on this list.
Will there be an interim step beyond the FDDI before getting to the ATM offering that suits both NAP users and other ATM users? Perhaps. There is alot of interest. PAC*BELL is not looking to having a seperate product offerings, but more having two catagories of customers under the same general product offering. When will closuer come? Warren doesn't know yet. He will work to get that information to the community as soon as possible. Part of the problem is that PAC*BELL did not get the production AIP cards until just 10 days ago. Mark from AADS is curious about the quality of the AIP cards they were using. The Bellcore work was done using earlier cards.
The ATM testing is the different from the testing the AIP issues. ATM issues should not be a part of the critical path in solving this problem. TCP preformance is. Warren says that is what he will get done in the next four weeks.
Colocation is not possible with PAC*BELL because of CPUC issues. Getting on the ring requires that the traffic would exceed 20Mb/sec.
