SE440017B - CLUTCH DEVICE FOR SYSTEM INDEPENDENT RECORDING OF CALL DATA - Google Patents

Description

T9Û3ZS9MS L / 'l use of external counters for a sorting and the output of the data thus produced as well as an invoicing. This registration of call data shall then require as little collection as possible.

A switching device for system-independent registration of call data and charges is admittedly already known in the past, but in doing so, however, charge pulses from the superior station are required for all processes. In addition, despite a considerable contingent, it is not possible to charge subscribers for a forwarding with fees.

The invention solves the said problem in that the lines leading from the subscriber exchange to a higher station are routed in a group over a connection device for station lines, that the subscriber lines to the subscriber exchange are connected in groups with a connection device for subscribers, that each station line connection device per station management contains a receiver for any counting pulses arriving from the parent station and a detector for selection pulse identification, including identification of call start and disconnection, that each connection device for subscribers comprises an identification device, by means of which it is determined which subscriber participates in an existing station connection, and that both connection devices via a control device are connected to a memory, in which the generated call data is stored until they are output by means of a sheet printer or other readable medium (hollow strip, magnetic tape or the like). s possibly sorted according to given parameters.

Since two types of connection devices, namely some for station lines and the others for subscribers, are provided, the assignment of each station line to each subscriber can be easily ascertained. Thereby, the recorded data, which belongs to each station connection, can be monitored and stored for further evaluation. In this way, according to a further education of the invention, redirected and forwarded conversations are also ascertained and evaluated.

V 'p' -n uq .. NLQ 'fi jp-inq 7903259-5 also call start and end, interval selection times, length and tolerance of polling pulses and pause times as well as special signals such as for private calls and call diversions. For subscriber exchanges, to which no charge pulses are transmitted, the start and end of the call are important, since with the call time and the distance to the selected local network, taking into account the time, the costs of the call can be calculated. The determination of interval selection times and pulse lengths serves for traffic measurements and for ascertaining errors in the system as well as for determining selection manipulations when dialing.

The special signals allow not only a statistical determination of the individual call types but also different processing of these calls for a settlement.

An example of the invention will be described in more detail with reference to the accompanying drawing. In it, all details which are not required for the understanding of the invention have been omitted. The individual units shown are known for their structure and function and can be constructed in different ways.

Above the dotted line is a standard subscriber exchange system. However, it can also be another telecommunications system which is connected to a superior system, in which counting pulses are generated at different distances, with which the connection leading to the same is calculated.

This system consists of a subscriber exchange NA, of a number of subscribers TN, which with individual subscriber lines are connected to the subscriber exchange NA, and the station lines AL, over which connections are connected, which lead to the parent station OVSt. Below the dotted line are the devices for system-independent determination of call data and for independent evaluation. Since the NA subscriber exchange can be of any structure and system, and the subscribers connect their outgoing connections with a finger pad or keypad, these devices are universally useful for any type of subscriber exchange facilities. No changes or preparatory work are required in the NA subscriber exchange NA. Even if no counting pulses are received from the parent station OVSt, this device can be used as will be explained later.

This device contains several connection devices for station lines ANA, a group of station lines AL being routed over each connection device.

The connection devices for subscribers ANT are likewise connected to a group of subscriber lines TL.

In the connection devices for station lines there are reception distributors per departing station line AL, which receive the counting pulses arriving from the parent station OVSt and at the same time prevent their forwarding to the subscriber exchange NA. These counting pulses are usually transmitted at a frequency of 16 kHz.

For each line AL, a detector for selection pulse identification (for pulse selection to the station OVSt) and a detector for coating and disconnecting the line are also provided.

In addition, these connection devices have devices for determining the beginning of the call. All station lines in a connection device ANA are interrogated at the same time as a scan address.

In addition, they also contain per line AL a transmitter, by means of which an identification signal generated centrally in a common device for connection devices ANG is applied to the part of the station line AL leading to the subscriber exchange NA. This signal is a tone frequency which, due to the division of the line AL by means of a reception divider, can also amount to 16 kHz.

The common device for connecting devices ANG contains, in addition to the already mentioned generator for the identification frequency, also a timer, a clock generator for generating all required beats, and a number This number is equal to the size of the group of subscriber lines tuned to the identification frequency.

TL, which are connected to a connection device for subscribers ANT.

The connection device for subscribers ANT contains 7903259-5 only components for simultaneous connection of all subscriber lines TL connected to it to the receivers in the common device ANG.

When connecting an outgoing connection to the parent station OVSt, the connection device ANA belonging to the paved station line AL is activated and from this the common device ANG and a control device SSP for all connected devices. The signals recorded in the connection device ANA are converted into digital connection signals. The control device SSP detects these signals and ensures that the following information is prepared from them: Date and time of occupancy of the station line AL, selected call number (local or long distance call), interval selection time, call start, length and tolerance of pulses and pauses in the selection pulse series, end of the choice, number of any charged pulses, disconnection of the connection, call time and charges per subscriber, special signals, such as one for private calls, permissions, call diversion, etc.

Some of these data are required for the calculation of fees, some for traffic measurements and statistical compilations, some for the determination of intended or unintended incorrect service of the facility - and early detection of errors, which have not yet been reported by the subscribers.

The data thus recorded or ascertained is temporarily stored in a memory SP together with the number of the calling subscriber TN until the end of the call and the further processing.

To determine the caller's number, he is identified at the beginning of the call, which is ascertained by the first counting pulse or by evaluation of the selection time.

For this purpose, the transmitter belonging to the occupied station line AL transmits the identification signal in the connection device 7903259'- 7 ANA to the station line AL leading to the transmission NA. Thereafter, one connection device ANT after the other is controlled by the control device SSP and all connect to the same connected subscriber lines TL in groups to the receivers in the common device ANG. As soon as in any of these groups the subscriber line TL is found with the identification signal, the further identification process can be interrupted and the result entered into the intermediate memory SP.

In a subscriber exchange system, it is possible to reroute or mediate a call one or more times between the subscribers and from or to the mediation site.

For a correct division of the fees, however, it is important to know which subscriber, including the one to whom the connection was redirected, how long it was connected to the station management AL in question. For this purpose, a post-identification is performed at cyclic intervals. The cyclic intervals are either measured by the clock generator in the common device ANG, which, for example, provides a post-identification every three seconds, or they are given by the arrival of counting pulses. .

The already known subscriber TN is then connected, depending on the insertion into the intermediate memory SP, after the connection of the identification signal to the station line AL in question with a receiver in the common device ANG.

If it is then established that this subscriber TN can no longer be reached over this station line AL, because a call diversion or forwarding has taken place, then the control device SSP causes a repetition of the complete initial identification, which is again performed as already described. The first call is provided with a corresponding switching signal and stored as terminated in the memory FS. All additional accrued fees are then attributed to the new subscriber.

With larger time intervals, for example once a month, the memory FS is read and written with these data corresponding to telephone bills and various lists are printed with the help of a BS printer. For this purpose, the stored l ~ are sorted. 79-03259-5. data according to different criteria and, if necessary, be provided with corresponding reference numerals. This is how a choice can be made according to subscriber connections, cost centers, area code. Local calls can be distinguished from long distance calls, service calls can be distinguished from private calls and cheap calls can be distinguished from more expensive calls, and calls with distorted pulse pulses are marked. All fee units per extension are summed or all individual calls with all detailed data, especially private calls, are printed. Based on targeted sensing, individual telephone bills are produced on forms, for example for hotels or hospitals, even for shorter time intervals. When using a special calculator, it is also possible to calculate and invoice on the basis of call data, such as call time and counting pulse distance for long distance calls to individual area codes. Various selection criteria are also conceivable for statistical and traffic measurement purposes.

If it is desired to build a less complicated plant, the calculator, sorting device and / or blade printer can be dispensed with and instead data recorded on a magnetic tape or a perforated strip, so that the sorting and printing can be performed with existing other devices, such as a computer. . A cheapening of the plant during optional omission of individual devices is also possible without limitation of the invention.
