AUTOMATIC TEST SYSTEM OF SATELLITE CONTROLLER

摘要

PURPOSE:To test automatically a satellite controller via a communication satellite channel by dialing a specific subscriber number from a satellite control exchange and a pseudo subscriber terminal device. CONSTITUTION:A controller 52 starts the pseudo subscriber terminal device 6 in calling, this connecting request signal is connected in a folding way among an earth station radio device 22, an antenna 23 and a communication satellite 4, and connected to a channel trunk of a satellite exchange 1. A dial pulse generator 54 transmits a special dial pulse signal to the exchange 1 in the said route after the confirmation of a dial tone, and when the exchange 1 receives the signal, a test trunk 51 is started and connected. Then, a channel check device 51 is connected between the trunk 51 and an interface device 53, and the device 55 tests the transmission of the channel. A specific subscriber number is dialed from the trunk 51 by the control of the controller 52 in case of incoming call, the signal is incoming to the device 6 via the communication satellite channel in the reverse route, the channel is completed by the response of the device 53 and the similar test is executed afterward.
