Abstract
Identification of data packets in switching equipment included in a telecommunication system and known as a packet switch. A plurality of incoming links are connected to the switching equipment via first switch ports, and a plurality of outgoing links are connected to the switching equipment via second switch ports. The equipment also includes control and coupling devices required to connect an incoming link with an indicated link, where the indication of an outgoing link is initiated by signals in the form of one or more data cells occurring on an incoming link. Additional information in the form of additional bits is delivered to the data cell in the first switch port and the additional bits are given a configuration which corresponds to the address information in the data cell. The additional bits are removed in the second switch port. The additional bits include a category identification and/or a function identification.
