Alternate Communication Channels

One of the best ways to handle availability of data from remote sites is to have alternate communications channels. In particular, these should have no common points of failure. This includes:

· Physically separated channels, so that channels in the same microwave link or fiber optic cable are not considered physically separate. Also entry points into buildings or sites need to be different.

· Different media, so that if one type of media suffers a failure, the other type is not affected (e.g. weather conditions affect radio-based communications)

· Automated switchover from one communications channel to the other within the performance requirements of the functions using the channels
