Abstract:
In a telecommunication system comprising a local telephone exchange, an access node connected to the local telephone exchange via a concentrating interface, a group of subscribers, and a data network, a method for preventing congestion in the concentrating interface by setting up a data connection directly between an access node and a data network based on a predefined status of a subscriber initiating a data connection, said method comprising:defining a status definition of either a voice subscriber or a data subscriber for each subscriber; storing said status definitions in the access node; receiving a call setup request from a calling subscriber in the access node; determining whether the status of said calling subscriber is voice subscriber or data subscriber by using the stored status definitions; preventing the received call setup request from being signaled further to a local telephone exchange, if the determined status of said calling subscriber is data subscriber; generating a dial tone locally in the access node for the calling subscriber, if the determined status of said calling subscriber is data subscriber; receiving and processing dialing from the calling subscriber locally in the access node, if the determined status of said calling subscriber is data subscriber; and setting up a data connection between the calling subscriber and the data network directly from the access node based on the received dialing, if the determined status of said calling subscriber is data subscriber.
