Reliability requirements for telecommunication systems affected by particle radiation

The principles for determination of reliability requirements are described and three types of reliability requirements (alert function reliability, service reliability, and maintenance reliability) are defined. Three reliability classes for each type of requirement are defined based on the acceptable soft error failure rate. Specific values are determined for each type and class of reliability requirement.
