US 5,632,017 A · Telecontrollable communication system having a remote transmission module

Abstract

A communication system equipped with a central computer means is connected to a service central via a communication network, for example, a telephone network of ISDN network, for telecontrol thereof. For the information exchange between the service central and the communication system, a teletransmission module is arranged in the latter, this telecommunication module being connected to the central computer means via a computer/bus interface and via a PCM-oriented system/bus interface. An information transmission via different communication networks, preferably via the telephone network or via the ISDN network, can be set using the teletransmission module. Due to the central arrangement of the teletransmission module with different information transmission procedures for different communication networks and due to the control of the call setup and cleardown for different communication networks by the central computer means that is possible as a result thereof, externally connectable transmission equipment (for example, modems) including a call setup and cleardown controller provided for this purpose can be eliminated.

Summary1,540 words

#The present invention is directed to a telecontrollable communication system having a central computer means to which can be connected via at least one PCM-oriented system bus interface subscriber line equipment, that is connectable to communication terminal equipment, and at least one trunk line unit. The communication system can be connected via a communication network to a service central for the purpose of an information exchange for telecontrol of the communication system.

#U.S. Pat. No. 5,047,923, hereby incorporated by reference discloses a communication system in which an administration and maintenance terminal (usually realized by a V.24 interface) is provided for the operation, the administration, and the maintenance and diagnosis of the communication system. Information communicated to or from an operations unit (for example an operator personal computer) connected to this operating interface is transmitted directly from or to the central computer means of the communication system via this administration and maintenance terminal.

#The telecontrol, that is, the teleoperation, the telemaintenance, the teleadministration and the telediagnosis, is effected in that the administration and maintenance interface is conducted via a private or public network to a service central. The transmission of the information to be communicated is implemented with a transmission equipment with whose assistance the digital information for the telecontrol of the communication system which is to be communicated is converted such that this information can be transmitted via, for example, the telephone network (that is, analog information transmission and telephone signaling) or via an ISDN network (integrated services digital network) that is, digital information transmission and ISDN signaling. For the call setup and cleardown of the connections for telecontrol of the communication system, a considerable circuit-oriented and program-oriented outlay is required both in the communication systems or, respectively, in the service central as well as in the transmission equipment.

Detailed description2,319 words

#In a block circuit diagram, FIG. 1 shows a service central SZE that is connected via a link AL to a communication network KN that is connected via a trunk VL to a communication system KS. The service central SZE, for example, is realized by a personal computer that is equipped with an access means to the communication network KN. A plurality of communication systems KS (indicated by dots) connected to the communication network KN are telecontrolled with the assistance of this service central SZE, for example, are teleoperated, teleadministered, telemaintained and telediagnosed. To this end, appropriate telecontrol routines realized in program-oriented terms are implemented in the service central SZE.

#For example, the communication network represents a telephone network or an ISDN network (integrated services digital network).

#In the illustrated communication system KS, the trunk VL coming from the communication network KL is connected to a terminal A of a trunk line unit VAE. The service central SZE as well as the trunk line unit VAE are fashioned in conformity with the provided communication network KN (telephone network or ISDN network). This means a corresponding circuit-oriented and program-oriented realization in view of the physical and procedural properties of the provided communication network KN.
