Abstract

PURPOSE:To execute a packet trace to only a designated line by implementing collection and output of packet data information through a registered trace object line. CONSTITUTION:When a registration request command for packet trace is outputted from a packet data collection input output means 30 to a maintenance operation means 13, a call control means 12 implements trace registration according to a command to a designated line. When a digital terminal equipment 20 makes a call, the call control means 12 acquires a line and uses a packet data collection means 11 when the line is a registered line to start the collection of a packet data. The maintenance operation means 13 starts the output of the packet data collected from the packet collection means 11 based on the data output request command from the packet data collection input output means 30 and outputs the data to the packet data collection input output means 30 via the maintenance operation means 13. Thus, packet trace is implemented to only the designated line.
