Abstract
The effective availability kE of a link system is expressible as the product of an average availability 
and an availability factor 
. A general expression is derived for for link systems providing access to trunk groups carrying smooth traffic. The value of obtained for smooth traffic is shown to be applicable to trunk groups offered random traffic. The validity of the theory is demonstrated by application to a three-stage link system and comparing the results obtained with the results obtained by using the methods of Jacobaeus.
