Abstract
A packet switch comprising a plurality of line interfaces each connected to a pair of input and output ATM lines, and a routing unit for transferring packets received from each of said line interfaces to one of the other line interfaces specified by the header information of the packets, wherein each of the line interfaces is configured to convert a group of ATM cells received from the input ATM line selectively into either a first type of packet in which ATM cell headers are excluded or a second type of packet in which ATM cell headers are remained, whereby management cells received from the input ATM line are relayed to said one of the other line interface by inserting said management cell into said second type of packet together with user cells on the same connection.
