DE2218510C - Circuit arrangement for telecommunications, in particular telephone systems, with two types of message transmission, for example telephony and data transmission - Google Patents

Description

Monitoring of the connection ufcd, the adaptation of the different character systems and the implementation of the data. An identification device JD with an associated controller JD-ST for determining the subscriber line number is also shown.

The establishment of a data connection can either be initiated by dialing a predetermined code with the dialing device of the telephone FG or by inserting or plugging in a perforated card or the like in a reader as data terminal DE > o, which first receives the corresponding code and after retrieval durcii the input-output controller EIA-ST of the data processing device DV sends out the actual data.

When one of the transmissions DUe is occupied and one of the inputs of the input-output controller EIA-ST is occupied at the same time, the latter triggers an identification request. Regardless of the fact whether this requirement is met immediately, you will receive the requesting participants in the form of a continuous tone, the request to enter the data.

Via the JD-ST controller, the pending requirements are sequentially i.bgewickel, e.g. B. in the form of a circuit test item, in the case of the occupied transmission DUe a test signal is connected to the existing connection path w.rü that is branched off in the subscriber circuit TS and sent to a new identification unit as soon as a result requested by the input / output control EIA-ST if the first complete data block has not already been entered, this is transferred and thus the prerequisite for the authorization check is fulfilled. In this case, an authorization check in good time is no longer possible. The subscriber therefore receives the busy signal and the beler. · Transmission DUe is activated.

i * 2 in the case of new systems of this type, the same Claim: tiliziereinrichtung for higher traffic routes gene. Circuit arrangement for telecommunication, in particular the invention relates to a circuit arrangement Sundere telephone systems, with direct control for telecommunication, in particular telephony of the individual elective levels and two types, with direct control of the individual elective levels communications (e.g., telephony and two types of communications and data transmission), in which the authorization (e.g. telephony and data transmission), in the One type of messaging allows one type of narration to pass an authorization check on the basis of an OK notification of an authorization check to H.ind supplied by a subscriber identification one supplied by a subscriber identification Result is dependent, which is dependent on this type of result, which is dependent on this type of result of central message processing central facility direction is made and which is made in the absence of and in the absence of an authorized person Authorization to send out a busy signal, to send out a busy signal and to sign and leads to the activation of the central activation of the central facility, Direction leads, thereby identified, a reduction in waiting times or a reduction in waiting times net, that the transmission of the calculation of the deduction of the market value is according to the invention check dependent message type is achieved in that the transmission of the already immediately after the message type that is dependent on this post-authorization check has been assigned set up receiving central processing immediately after the occupancy of this post-installation (DK) is released and a set up receiving central processing facility Transmission of the busy signal then takes place, direction is released and a transmission de> if the identification result occurs up to the end of the busy signal even if the Identides Arrival of a given group of assessment results until the end of the arrival of a Messages (e.g. of the first data block) are not given a predefined group of messages, located. According to the invention, a subscriber receives immediately after an input has been assigned to the Da 30 processing device and independent of the Authorization check the request to enter data. He doesn't need to wait until It is already known to identify its subscriber line and the data for existing telephone networks the transmission of additional data to be processed is communicated. The Identifi benefits and, in conjunction with a central data device, this saves time to deal with these too Processing facility special services, such as. B. To be able to do the request. This period of time Obtaining information, placing orders is based on the input time for a preliminary or collecting predefined data. given group of characters; expedient becomes a "Block" can be specified as the data terminal at the subscriber station, since it generally means that the either the phone itself or a special processing procedure is initiated. If on tes device, e.g. B. a punch card reader, serve. The end of a data block is the identification result of the setting of a data connection takes place in the same data processing device not yet communicated rather like the production of a telephone connection and thus no qualification test through binding by dialing a predefined code that can be performed, the busy signal is sent and when using a separate data terminal 45 the assignment of the input to the data processing council can also be sent automatically. establishment canceled. In order to ensure that only authorized part of the total, the waiting Participant access to the data processing device noticeably reduce times for the participant. Other and the various data services, on the one hand, which the identifying devices are equally speaking Utilities are allocated, keep 50 busy so that lower peak traffic, the requesting participants can be used as a basis for identifiers, zier ?, and the identification result of the data processing. Further details are based on the in the transfer facility. Only when so that the drawing shown block diagram of a AusVoraussetzungen for Bereehtigungsprüfung ER- execution example described in more detail: are filled, the emission of a check 55 is earlier than the Teilnehmcrstelle TLN consists of a Fernforderungszcichens for data input to the telephone set FC and from a data terminal EN subscriber causes . Is the authorization for the in the form of a card reader. Both devices are not provided with the data service used, so the same connection line is connected, which communicated a busy signal to the subscriber and the subscriber circuit TS is connected to a call seeker AS the occupied input to the data processing device 60 as a preselection stage. Activated via the follow-up. constricting group selector GW are different Should such data services be achieved subsequently in connection sets. The connection sets VS standing systems with direct control of the cinzel are introduced in a known manner for the processing of NEN dialing levels, so there is the telephone connections, while the data connection risk that the data generally only fertilize for the central data processing device Identification device, the DV via the transmissions DUe and all the increased load only with increasing waiting times for common input-output control EIA-ST , which subscribers can take over. On the other hand, these transmissions are used in a known manner
