Protocol test equipment and test method in remote protocol test equipment

摘要

In the present invention, when a plurality of protocol control points (PCOs) are to be tested as in the B-ISDN protocol, each control of the object under test (IUT: Imprementation UnderTest) A protocol test apparatus and a test method in a remote protocol test apparatus that can remotely control events (protocol primitives and protocol data units) that occur at observation points from time to time. In the B-ISDN protocol test, It is possible to check and control the operation of the target protocol from each control observation point by remote test equipment by providing means for control observation at lower layer and management layer so that more test items can be remotely tested , And the test coordination protocol is bidirectionally communicated by a simple timer and module configuration Can operate in mode, it is possible to grasp and control the status of the protocol in the test subject spherical water immediately at the remote protocol test device.
