Abstract

PURPOSE:To enable the selection of speech by operating the terminal of an attendant board without depending on the operation of an extension terminal by calling the terminal of the attendant board and selecting either of two speech paths is connected to the terminal of the attendant board, after completing the connection of the extension terminal. CONSTITUTION:When a signal to request the call of an attendant board terminal 5 is transmitted from a first exchange station 1 to a second exchange station 2 by a signal transmitting means 6, a connecting means 7 analyzes this signal and provided at the second exchange station 2 so as to connect two speech paths 8 between the first and second exchange stations 1 and 2, to call the attendant board terminal 5 and to connect the attendant board terminal 5, extension terminal 3 and trunk line terminal 4 through the speech paths 8 by the response operation of the attendant board terminal 5. Thus, without depending on the operation of the extension terminal 3, it can be selected by operating the attendant board terminal 5 whether the extension terminal 3 or the trunk line terminal 4 is released from a call.

The present invention relates to an other-station relay recall service, and more particularly, while an extension terminal accommodated in a first switching center and a central office line terminal are talking, the extension terminal is operated to be accommodated in a second switching center. The present invention relates to an other station relay stand recall system that calls a relay stand terminal and uses a response from the relay stand terminal to place an extension terminal and the relay stand terminal in communication.

Recently, a method has been adopted in which relay services for private branch exchanges installed in each building are concentrated in a single building's switching center, and operator services are provided through trunk lines between buildings. This is because, with the expansion of buildings, intensive nighttime and holiday services and directory assistance services are becoming necessary.

In the figure, a relay terminal is installed at exchange A, and no relay terminal is installed at other exchanges B, C, D, etc., and the extension terminals and central office line terminals of other exchanges require relay service. When this happens, the operator calls the relay terminal at exchange A and receives the operator's service. For example, when a central office line terminal connected to exchange B wants to connect to an extension terminal at the same exchange B, if the extension number is not known, the central office terminal at exchange A is called and a connection request is made. After the extension terminal is connected, exchange A and B
Since there is no need for a round-trip trunk line to and from the switching center, a method is used in which the central office line terminal and the extension terminal are directly connected in the B switching center and the connection with the relay terminal in the A switching center is released.

However, while a subscriber at a central office line terminal in exchange B is talking with a subscriber at an extension terminal, it may be necessary to call a subscriber at another extension terminal within the same exchange. In this case, it becomes necessary to call the relay terminal of exchange A again and receive operator service. That is, a service method for recalling other station relay stations is required.

[Scope of Claims] While an extension terminal housed in a first switching center and a central office line terminal are talking, an operation of the extension terminal calls a relay terminal housed in a second switching center, and the relay terminal responds. In an other-station relay recall system in which the extension terminal and the relay terminal are in a call, a call to the relay terminal (5) is sent from the first exchange (1) to the second exchange (2). A signal sending means (6) capable of sending out a requested signal; and by analyzing the signal, two communication lines (8) are established between the first switching center (1) and the second switching center (2). ), call the relay console, and respond via the relay console terminal (5) via the telephone line (8).
), a connecting means (7) for connecting the extension terminal (3) and the central office line terminal (4), and a connection means (7) for connecting the relay terminal (5) and the central office line terminal (3), or for communication between the trunk terminal (5) and the central office line terminal (3) or between the central telephone terminal (5) and the central office line. Another station relay stand recall service system characterized in that selection of a call on a terminal (4) and selection of release of an extension terminal (3) or release of a central office line terminal (4) are performed from a relay stand terminal (5). .
