EINHEITSAUSTAUSCH IN EINEM DATENPAKETWEITERGABEKNOTEN

The invention relates to a method for implementing a unit changeover in a telecommunication node forwarding packet data. In accordance with the invention, the traffic aimed at the channels of the unit to be changed is buffered, and the transmission buffers of the unit to be changed are emptied by transmitting data contained in them to its destination. Following this, the replacement unit is switched to the channels of the unit to be changed, and the information of the node is updated to correspond to the new configuration, and the reception of the incoming traffic from the line is begun. Finally, the outgoing traffic is activated by releasing the buffered traffic through the replacement unit.
