Abstract

PURPOSE:To enable a network test by using an existing hardware as it is, through closing of a line concentration stage network, by a loop circuit formed with an arbitrary channel line at a relay line side of line concentrated. CONSTITUTION:When the A relay is operated with the operation panel 26 at the space split inverse line concentrator 17 to close the contact (a), and the loop of contact (a) and resistor R is formed to an arbitrary channel line at relay line side. The order closing the link tying an arbitrary subscriber and the relay line from the panel 26 is transmitted to the control circuit 23 at line concentration side via the station side control circuit 25-station side information transmission/reception circuit 22-line concentration stage side information transmission/reception circuit 21. With the order of link closing, the DC bus of charging circuit 19-charging switch 14- switch element of space split line concentration device 15-relay line 16-contact a-resistor R is closed and it is made the same as calling state by scanning the subscriber terminal.
