PATH CONNECTION CONFIRMING SYSTEM

摘要

PURPOSE:To confirm simultaneously connection of plural control and sound channels by providing a folding function where transmitting and receiving terminals are connected in cascade between the control and the sound channels. CONSTITUTION:A specific data is inputted from a transmission terminal Tx in a test device Ei after the connection of lines is finished as shown in dotted lines by transmitting a specific control signal from the test device side Ei to a trunk device TRKj side, the data is received by a receiving end Rx in the test device Ei via a control channel C, the 1st sound channel and the 2nd sound channel connected in cascade. The propriety of all lines is confirmed in the lump by comparing the specific data from the transmission terminal Tx in the test device Ei with the specific data received at the receiving end Rx.
