| Abstract: | It's very important that how cisco 8450 works in ATM asynchronous optical communication. The kernel controlling unit CPU of cisco 8450 is not only the most key component but also a fragile one, if the CPU runs trouble, the communication net in whole power station will be stopped. This paper draws out a resolving scheme, called non-redundant CPU about cisco 8450, which introduces two respects about it in detail, the automatic receive and the manual dial. |
