Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic register closing system in an automatic register testing device.

Centralized testing equipment (hereinafter referred to as MT
When starting up and testing each device from F), test information is required to specify the various devices. Sending depends on the number of cables and the MTF deployment tree.

Therefore, since a normal call is not blocked and activated, if it is blocked and activated, it is regarded as a test, and test information is created based on this. This will be explained below using figures.

Figure 1 shows the conventional automatic blocking system, where IR is an input register, MB relay in IR is a relay for receiving blocking information, and contact a
is the activation reception relay from the human trunk, is the ground air supply relay for control within the IR, ba is the auxiliary of the B relay, rp is the connector relay with the marker, IRMC is the connector between the IR and the marker, M is the ma' The TST relay is a test information receiving relay.

Although the IRL is not shown, the incoming register link connects the incoming trunk and the IR, the CSF is the central monitoring rack that monitors and blocks the busy state of each device, the BL is the busy lamp, the MB is the blocking jack, and the ACT The tree in ACT is an IR deployment tree, ir is a relay that operates during an IR test, and MBK relay is an empty confirmation relay. A conventional automatic closing method will be described with reference to FIG.

In the case of a general call, although not shown, the IR from the incoming trunk
L is activated and begins IR selection. RL is IRl, which is an empty IR, where earth air is sent out in the RGBY lead.
Select and connect the incoming trunk and IR. Although not shown in the IR, number information is received from another station via the incoming trunk and a marker (M) is activated via the IRMC. At this time, since 1R is not blocked, no TST information is sent. Next, when testing from MTF, the maintenance person inserts a jack into the corresponding 1R (7) MB in the CSF, blocks the IR, and then starts 1RL.In IRL, MTF is activated by starting from MTF regardless of the RGBY lead. I specified from
Select R. The IR receives number information from the MTF via the incoming trunk and activates the marker (M) via C. At this time, since the jack is inserted in MB, the marker (M
) TST information is sent to. Next, regarding ACT, 1R is sequentially closed and all functions of the IR are automatically tested.Although not shown, a tree is first expanded to specify the IRO, and the RGBY leads of the IRO are expanded. and MB lead is pulled into ACT.

If there is air in the RGBY lead, the IR is identified as empty, the vacancy check relay (MBK) relay operates, and air is supplied to the MB lead through the Mbk contact. ACT connects IRL and IR in the same manner as MTF, and sends a test number to IR. IR by receiving the number
Activate the marker via MC. At this time, A to MBlJ-do
Since earth air is supplied from CT, TST information is sent to the manufacturer. Using the above-described method, tests are carried out by sequentially changing the deployment tree up to IRn. The above is the conventional automatic closing method, but in this case, RGBY and M
The two B leads must be pulled in, and two circuits are required for the deployment circuit in the ACT.

The object of the present invention is to solve the above-mentioned drawbacks, and to provide a 4-register automatic blockage method that is capable of performing register blockage processing with only one MB lead corresponding to the register under test. be.

In order to achieve the above object, the present invention provides that when a register of a common control automatic exchange is activated while the register is blocked, the marker is set to 9' by the blockage air. Test equipment that has a circuit configuration that sends out test call information when the register is empty or when the marker is activated, and that automatically closes the register and performs the test. The blockage lead is then monitored, and if it is empty, the timing of the marker operation time is further monitored, and if the blockage lead is still empty after this timing, the register is determined to be free, and the blockage lead is The feature is that the blockage is performed by sending out the earth's air.

Embodiments of the present invention will be described below using the drawings.

FIG. 2 shows a specific circuit example of the register automatic closing system according to the present invention. The operations from the general call and MTF in FIG. 2 are the same as in FIG. 1, and will therefore be omitted.

In FIG. 2, the same symbols as those in FIG. 1 indicate the same devices and functions, and will therefore be omitted. The IRS relay in the automatic test equipment (ACT) is a relay that activates the input register (1R) and monitors the IR availability. The BY relay is a busy monitoring relay for input registers, the BYT relay is a slow recovery relay that covers the operating time of the marker (M), the busy identification relay for the IRB stop register (IR), and the MBK relay is for checking when the input register (IR) is vacant. Shows identification relay.

For the ACT test, first, a trigger is set to designate the IRO, and for the IR test, an IR relay (not shown) is activated.

The IR relay operation activates the BY and BYT relays.

BY, BYT relay operation activates IRS relay,
Switch the BY relay to the MB read side. At this time, (1)
If the IR is blocked due to a failure etc., the BY relay will be restored because there is earth in the MB lead. BY relay recovery V
) (Jiki) - 1rs make - Mbk break - 1rby
Break-By Break-1 The IRBY relay is operated by the RBY coil 1 (battery), identifies IR busy, and moves on to the IR test of the next line. Next, (11) If the IR is in operation and before the marker is activated, that is, while information is being received, the MB read is open, so the BY relay is restored in the same manner as above, and the IR busy status is identified.

Next, if 0!0IR is empty or the marker is activated, (earth) - BY coil - 1rs make - Mbk break - tri-MB terminal 1 (if IR is empty) b break - Ba break -MB coil (battery) (if marker is activated) Rp make - TST terminal - Ra make - TS
BY relay will not recover due to T coil 1 (battery).

Furthermore, due to the IRS operation, the slow recovery relay BYT that covers the marker operation time starts recovery, and if the BY relay is still operating when BYT is recovered, (earth) Ir

! ) MBK relay operates. In other words, the MB read is monitored taking into consideration the marker operation time, and if the BY relay does not recover during that time, the BY relay is held by the battery that has passed through the MB coil, so the IR is identified as empty and the MB is read.
K relay operates. The MBK relay operates to switch the MB lead, send out the earth air, and close the IR. The subsequent operations are the same as in the conventional method. As described above, the blocking method according to the present invention requires monitoring only the MB lead, and has the advantage of reducing the number of cables and tri-circuits.
