Description

7802725-7.

A presently proposed embodiment of a device having the features significant to the invention will be described below with simultaneous reference to the accompanying drawings in which Figure 1 schematically shows parts of a device for a current subscriber exchange and Figure 2 schematically shows the device in connection with a data transmission facility.

In Figure 1, the current gear PABX is symbolized by a register REG and B extensions. The exchange is in a manner known per se provided with a unit pD, for example of a microcomputer type known per se, which unit senses the telephone traffic occurring in the exchange. Both internal and external telephone traffic is sensed. The unit is arranged to exercise control function within the gear unit in a manner known per se, for example to effect selector influences.

The current exchange includes a so-called referral service, ie a service where calls to a referral-connected B-connection are transferred to a waiting point or to a telephone operator with the FMA intermediary, from which the caller receives information that the B-connection in question is not available.

In accordance with the idea of the invention, a computer equipment, preferably separately in relation to the exchange in general, is to be used as an information collecting means for the reference service.

Said computer equipment is provided with one or more terminal devices A1 and A2, wherein in the figure one terminal device A1 is intended to be included in operator-associated equipment and the other terminal device A2 is used as a fitting device.

With the respective of the said terminal devices can information. connected to the referral service is inserted into the computer equipment HD. The mentioned information may include that the B-connection or B-connections in question are not available or can be found, possibly connected with additional information on, for example, time of return, name of the B-connection, etc. The said computer equipment and terminal devices are arranged so that the information entered into the computer equipment 7802725-7. can be presented on the terminal device in question for the person handling the referral service or the guarding service.

The said computer equipment HD is connected to the unit uD which, in addition to sensing the traffic in the exchange, also senses the information entered in the computer equipment HD for the B extensions which are currently connected to the reference service. Therefore, when a call arrives at a B extension, which has informed the call center or the operator that he is not available in addition to any other information and this information has been entered into the computer equipment from the terminal device concerned by the operator or equivalent person, said unit reacts through the connection to the computer equipment HD and arranges for the call to be transmitted to the call center or the operator by influencing the relevant means in the subscriber exchange in a manner known per se. At the same time, the call center or the operator automatically receives from the computer equipment the information entered in the computer equipment for the extension, which information is presented in a suitable form, for example on a display. In this way, the referral service is significantly facilitated for the telephone operator or equivalent person who does not need to distinguish the B extensions with internal notes.

In the event that the operator is called directly from outside and a certain extension is sought, the B extension can be called from the transmission device FMA via the unit pD, after which the operator receives information about the extension via his telephone.

In the above example, communication between the unit pD and computer equipment has taken place directly. According to the invention, however, it is possible to also allow communication between said means to take place via a data transmission system which comprises a control unit CPU which provides several services, each of which is assigned to its additional computer equipment HDI. In the figure, the bus connection of the data transmission system is shown with BUS.

Respective computer equipment H can be equipped with its own terminal device. Two or more computer equipment can be controllable with a common terminal device, etc. 7ao2v2s-7 Figure 2 is intended to show the case where the unit} 1D and the computer equipment HD communicate with each other in both directions via a control unit CPU in a data transmission system.

The said control unit can then be programmed to supply additional information to the one introduced in the computer equipment HD, for example if flex time function is integrated with the exchange, information can be given to a caller in connection with the reference connection when stamping has taken place for the extension in question. A number of time clocks S or equivalent are therefore connected to the computer equipment HD3, which provides individual information to the computer equipment m3, which individual information of the CPU can be transferred to the terminal apparatus A1 for the computer equipment HD so that the time task in question is presented on said terminal apparatus.

Figures shown in the figures HDI - HDS, whereby HDI is attributable to individual call debiting, HDZ to directory information, HD3 to information on flex time, HDI »to programmable number groups, and RDS additional information on so-called national blocking. The unit T constitutes a writing and reading unit with teletypes, monitor, etc. and with the aid of the CPU information can be transferred between optional computer equipment of the computer equipment shown. Box K is intended to indicate the speed dial selection function within the exchange.

The invention is not limited to the embodiment shown by way of example above, but may be subjected to modifications within the scope of the appended claims.
