摘要： PURPOSE:To perform switching connetion without changing subscriber number, by providing a device which switches a subscriber to another station if a telephone station is in failure for connection and changes the number of one station to the other station number for a relay line between the other station and a relay exchanger. CONSTITUTION:If a station A is in failure and connection is impossible a subscriber (a) is changed over to station B with a changeover switch SW. When subscribers (c), (d) in stations C, D perform a telphone call to a subscriber (a), the call to the station A is in failure and detour connection from the stations C, D to relay exchanger TDMS is made. When the call of the number of the station A is taken place on a relay line between the station B and the exchange station TDMS, conversion is made to the number of the staton B with a number converter TLRF. The exchanger TDMS is provided with a station A subscriber number detector RCLE to perform detour connection of the call of the station A to the station B, if the station A is in failure. Thus, even if the station A is in failure and connection is impossible, the station B subjected to switching connection performs incoming/outgoing connection lwithout change the number of subscriber.

CONSTITUTION:At connection test, based on the test number stored in the control unit CPE, a dial pulse is delivered from the dial pulse generating unit RSATE to the telephone exchanger via the test line, and after the end of delivery, the incoming side of the test line is reconnected to the failure identifier OGTATE to monitor the connection to automatic concentration test trunk ACTT and the connecting condition of communication path. Further, a failure is identified at the failure identifier, the selector OT holds the line connected to the outgoing side of the test line and stores the failure information to the control unit CPE. Thus, the test is automatically conducted and the test line is selected to other lines in case of failure to continue the test.
