Abstract

PURPOSE:To realize a test trunk function, by connecting various tone generators at each one channel in common to a time division channel device and switching the bus of the time division channel device in high speed sequentially for the connection with a trunk line. CONSTITUTION:A trunk line from an opposing station is connected to a time division switch TDSW and a DE lead is connected to an incoming side of the switch and an AB lead is connected to the outgoing side. On the other hand, a tone DTONE in 1kHz of frequecy and a digital ring back tone DRBT are connected to the incoming side of the TDSW by one channel each. When the sequence for the test trunk function is to transmit 1 DRBT, to terminate 2,600OMEGA and to transmit 3 DTONE, first the bus of 1 is connected with the bus control of the TDSW. Next, the bus of 2 transmitting an idle channel pattern F is connected at the outgoing side of the TDSW. Further, through the connection of the bus 3 for the transmission of DTONE, the function of test trunk can be realized.

If it is a B transmission, the path (3) is connected by path control of the time division switch (t) and the TDSW (t). Next, on the output side of the time division switch, connect the no-call pattern 7Ft--the path (2) to be sent. Furthermore, by connecting the path (■) to send out 1kHz)-on DTOWE, the function of Terotori Drunk is increased to 5! Since the present time division switch TD8W can switch paths at high speed (1 ms or less), it is possible to easily connect multiple tones faster than a test trunk using a relay.

するという効果がある。As explained above, this Ij1 takes advantage of the high speed of the time division switch and the ease of connecting multiple tones, and connects each channel of tones required for the test trunk to the time division switch for testing. According to the trunk sequence, the tone and trunk line are sequentially connected by path control of a time division switch. This has the effect of eliminating the need for a conventional time division switch, which requires four test trunks depending on the traffic, and also requires a tone distribution circuit and a switching relay and relay control device for each test trunk.
