ABSTRACT:
The invention concerns methods for testing a connection either between a central controller of a communication network and a terminal of the network, or between two terminals of the network. In both cases, a terminal sends test pattern data which is to be echoed back by another device over the connection to be tested. In certain circumstances, a terminal may register twice with the central controller, in order to be able to establish the required test connection without disturbing existing connections. The invention also concerns devices for implementing the methods. The invention can be used in a Hiperlan 2 network.
