This interface is extremely mission critical to the point that a 99.9% uptime will not be acceptable. I have the following questions: 1) Bell Atlantic assures us that, because of the redundancy, we can expect 100% uptime from the OC-12. I would like feedback as to whether this is a realistic portrayal of the SONET environment.
How many significant digits do you consider acceptable? Even in an ideal APS environment, link failure detection and protection switching does take finite time. You might get 99.999% uptime, but probably not 99.9999999%. Methinks that you've been subjected to Marketing. ;-) Tony
