Definitions

  • the invention relates to a digital telecommunications device in which any number of connection modules for subscribers or extensions is grouped around a digital switching network, which together with a plurality of control parts and in particular at least one module for the detection of A switching center forms part of the internal functions belonging to the operating functions and can be connected to other subscribers via a further switching network (e.g. the public network).
  • a further switching network e.g. the public network
  • telecommunication systems are switching systems (private branch exchanges or local exchange systems or long-distance switching systems) which establish (switch) connections (lines) between two terminals (subscribers) A and B.
  • Terminal A transmits a phone number to the PBX and the PBX automatically switches the selected terminal B.
  • Device B only receives the connection request signals (the doorbell rings). The voice connection is only established when someone activates device B ("picks up").
  • Older switching systems established a physical connection via a rotary selector - which in principle simulated the "plugging process”.
  • Modern - digital - switching systems no longer produce real electrical individual connections, but select digital (logical) channels from a supply of digital channels for connection.
  • a special wire connection is no longer established between A and B, but only a logical connection (digital switching matrix).
  • a modern ISDN PBX mediates digitally and it supports digital - instead of analog - connections.
  • a continuous (end-to-end) digital connection is established.
  • the digital connection can be a "voice” or "data channel” - although this is transparent to the PBX, i. H . it cannot "notice” whether there is talk over this connection or whether data is being transmitted over it.
  • Service intervened because it has the monopoly over "real time” language switching.
  • the 1 TR6 on the main connection in traffic with a local exchange is the standard and the DKZE protocol (agreed by the ZVEI with the post office) on the private branch exchange.
  • PBX extensions "sub-mediate" incoming calls, and all possible combinations occur, in particular a local exchange can again be a sub-exchange of a long-distance exchange.
  • V-2 connections In known telecommunications systems, special devices are connected via data lines (mostly so-called V-2 connections), specifically
  • the present invention is concerned with designing a device of the type mentioned at the outset in such a way that it is easier to handle and to maintain.
  • the module can be selected for recording the internal states belonging to the operating functions.
  • the invention consistently makes use of the ISDN technology of the respective PBX, so that other types of connections (for example V 24 or connections deviating from the subscriber circuit) are no longer required.
  • connection technology according to the present invention not only enables
  • all seats can also be removed (remote), i.e. can be connected via other telecommunications systems (e.g. public exchanges) without special connection technology (modem) or the like. to use.
  • remote i.e. can be connected via other telecommunications systems (e.g. public exchanges) without special connection technology (modem) or the like. to use.
  • modem connection technology
  • connection is a "normal" ISDN connection without any change in the signaling protocol.
  • This connection technology has the following advantages over the conventional one: It can also be used to maintain, diagnose and parameterize smaller PBXs "remotely”.
  • a switch consists of the protocols for the participants and the switch.
  • the B channel is the voice / or data channel (the "line").
  • the D channel is the switching channel with the corresponding switching protocol (signaling protocol or D channel protocol).
  • a signaling channel can (need not) switch more than one B channel (for the standard connection 2, more for multiplex connections, eg 30 for the primary multiplexer).
  • the protocol in the B channel is not standardized for data transmission, with speech it is "the language", i.e. protocol levels 2 to 6 are empty, layer 7 is the PCM (pulse code modulation) of the language.
  • the B channel is conveyed transparently, ie what is transmitted and how is an end-to-end protocol agreement (with the service features language and data).
  • An end-to-end protocol agreement (with the service features language and data).
  • a wide variety of agreements are possible for the data, e.g. B .:
  • the present invention is based on a protocol between subscribers (A or B) with the switching system
  • the invention comprises the layer 1 communication protocol
  • Layer 1 is a physical ISDN connection that the switching system provides for digital ISDN terminals.
  • Virtual subscribers are intelligent units in the switching system, e.g. B. the diagnostic server, the status server, the parameterization server.
  • the connection between the operator station (like a participant A) and the virtual participant within F (participant B v ) is established in exactly the same way as the connection between A and B (via F).
  • Only the subscriber B v is not outside the switching system, but inside (eg on the "PCM-Highway" as a subscriber circuit. You can therefore select these operator functions with it - like normal B subscribers. That means the connection to The internal intelligence of the system is made exactly like the connection to an external one (e.g. a telephone or data terminal).
  • the "virtual subscriber" is represented by an intelligence unit embedded in the system, which behaves like a data terminal. However, this has access to the TK internal resources and states so that all requested operating functions can be fulfilled.
  • a subscriber circuit (subscriber module, usually a component insert with about 4 or 8 terminal connections) for the mediation of end-to-end communication is replaced by a subscriber circuit which does not necessarily have external connections, but does so via a normal one Called number of selected B channels can be recognized as an "internal" terminal.
  • the data exchange required to operate the PBX takes place between this internal data terminal (virtual subscriber) and the operator station (e.g. a PC).
  • the virtual subscriber (possibly in contrast to the normal subscriber circuits) has access to the resources necessary for the operation.
  • the switching center shown in the figure contains a plurality of connection modules for the individual subscribers, but only two are shown in the drawing. These connection modules are connected to the internal switching network, which in turn can be connected to the public network or other switching centers.
  • the module for recording the internal states which has already been mentioned several times, is also arranged within the switching center. Arrows indicate that the most diverse information can get into this module.
  • connection module which, like the other connection modules, can be connected to the switching network, as indicated by a dash.
  • connection module from the outside, from the subscribers, or only from very specific subscribers, via the switching network in order to carry out desired functions.
