Abstract

A method retrieves subscriber identifications in a communication network having multiple sub-scribers which are connected to a ring-shaped transmission path. A first telegram is outputted onto the ring-shaped transmission path which comprises a sequence of telegram fields, wherein each subscriber is allocated a telegram field for entering its subscriber identification and each subscriber checks during the passing-through of the first telegram if the subscriber identification field allocated to the subscriber is vacant, and upon detecting a vacant subscriber identification field enters its subscriber identification.
