Abstract: PURPOSE:To confirm that the titled unit is connected normally to a DCE, by allowing it to have a function for testing whether it is connected normally to a terminal connecting device or not, at the time of installation. CONSTITUTION:As for a communication control equipment 11, when a power source is turned ON, a connection test is started. A calling command is sent out to a DCE (Date Circuit Terminating Equipment), a three-second timer is started, a 'selecting signal sendable' signal from the DCE is awaited, and unless it is received within three seconds, it is decided to be an abnormal end. When the 'selecting signal sendable' signal from the DCE is received, it does not sent a 'selecting signal' to the DCE but waits for a 'disconnection instructing' signal from the DCE due to six-second time-out of an X21 protocol. On the other hand, the timer of ten seconds is started in advance, and unless the 'disconnection instructing' signal is not received from the DCE even after having waited for ten seconds, it is decided to be the abnormal end. When the 'disconnection instructing' signal is received within 10 seconds, it is decided that this communication control equipment is connected normally to the DCE.
