Abstract
The invention relates to a procedure for the processing of an unexpected disconnect request in an access node (AN) which is connected to a local exchange (LE) over a V5 interface. In the access node (AN), call setdown is effected by means of a disconnect message, which is sent from the local exchange (LE) and on the basis of which the call resources in the local exchange (LE) are released. According to the invention, the resources reserved in the access node (AN) for the call are preserved. Moreover, the local exchange (LE) is informed that the subscriber is busy, thus preventing the occurrence of an undefined condition between the local exchange (LE) and the access node (AN).
