Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a re-acceptance method that facilitates the re-acquisition of a held line when a station line is held at a station line reception desk.

In general, a reception desk that accommodates a large number of subscribed lines requires lamps and control buttons depending on the number of subscribed lines, or a system in which held lines are accepted by operating numerical buttons corresponding to the line. However, in reception desks with a large number of accommodating lines, there were problems such as the number of buttons increasing, or the number of button operations needed to reacquire.

The present invention seeks to solve these problems.
In other words, since it is thought that only a few lines can be put on hold at the same time even at a reception desk that accommodates a large number of people, a device is installed that can store the accommodation position information of each line on hold, and the line can be put on hold with the touch of a button. This allows the line to be reacquired.

A case where a relay circuit is used as an embodiment of the present invention will be described below. In addition, this explanation is based on the case where one reception desk can accommodate a large number of lines (100 lines in this case).
Although this is carried out for a case where a reception desk is accommodated, the same concept can be applied to a case where a reception desk with several reception desks is used.

Fig. 1 is a block diagram of a switching system related to a reception desk according to the present invention, Fig. 2 is a block diagram for storing trunk (line position) information according to the present invention, and Fig. 3 A to C are diagrams of this function using a relay circuit. It is a circuit diagram of the main parts.

In FIG. 1, a trunk information control unit A is a control unit for storing trunk position information at the time of hold in a storage unit, and a trunk information storage unit B is a circuit station line for storing trunk position information at the time of reconnection of the held trunk. Trunk C is a trunk for making calls to the central office line, receiving calls, putting calls on hold, etc. Further, the trunk connection control section D is a control section for connecting the office line trunk C and the reception desk F, and the trunk connection section E is a circuit for establishing a call route connection between the office line and the reception desk F. F is a control console that performs reception operations with central office lines and the like.

FIG. 2 shows the configuration of circuits A to D and the numerical display section.

In the relay circuit shown in FIG. 3, the central office line trunk is held by the central office line holding operation of the reception desk operator. At this time, the H relay of the office line trunk C shown in FIG. 3A is activated. This H relay operation activates the trunk information storage control section A, and operates its TG1/0-9, TU1/0-9 relays and check relay TK.

The vacant trunk information storage section B is selected by the operation of the TK relay, and the C1/0 to n relays of the trunk information storage control section A corresponding to the vacant storage section B are operated as shown in FIG. 3C. . This C1/0~
The check relay CK is activated by the operation of the n relay. At this time, the K relay of the office line trunk C that caused the activation is operated to disconnect the activation circuit, thereby preventing the control section A from causing activation again. Further, the operation of the CK relay of the control section A operates the connector relay H of the storage section B, and transfers the trunk position information to the storage section B as shown in FIG. 3A. That is, the relays 1A to 8A and 1B to 8B of the storage section B operate based on the position information, and the check relay OK shown in FIG. 3C operates. The operation of the OK relay causes the RL relay of the control section A to operate, thereby restoring the control section A. As a result, the information on the central office line trunk is stored in storage section B.
The trunk number is displayed on the number display section of the reception desk as shown in FIG.

When re-capturing a central office line trunk that is displayed on hold at the reception desk, activate the trunk connection control section D and trunk information storage section B shown in Figure 3B by operating the individual connection button corresponding to the number display section. , the control section D operates the P relay, and the storage section B operates the S relay. The operation of the S relay causes the T relay to operate, and the trunk position information stored in the storage section B is transferred to the trunk connection control section D. When the connection button is restored, the S relay is restored, and the T relay begins to recover slowly. During this slow recovery time, the RL relay is operated to recover all stored information. In this way, the trunk connection control section D acquires the central office line trunk C again based on the information from the trunk information storage section B.
