Der Anschluß einer Nebenstellenanlage an ein öffentlichesThe connection of a private branch exchange to a public one
Netz mit der Möglichkeit mehrere Externgespräche gleichzeitig führen zu können, kann auf unterschiedliche Weise realisiert werden.The network with the possibility of being able to make several external calls at the same time can be implemented in different ways.
Beim analogen Anschluß werden mehrere Kupferdoppeladern benötigt . Dabei kann pro Doppelader ein Gespräch geführt werden .Several copper pairs are required for the analog connection. One conversation can be held per pair.
Beim ISDN können auf einer Doppelader bereits 2 Gespräche geführt werden. Bei höherem Kapazitätsbedarf werden mehrere Doppeladern benötigt. Diese Konfiguration ist bereits in ITU- Empfehlungen enthalten (siehe auch FIG 1 und [1] , Seite 81,82) .With ISDN, 2 calls can already be made on a twin wire. If more capacity is required, several double wires are required. This configuration is already included in ITU recommendations (see also FIG 1 and [1], page 81, 82).
Bei sehr hohem Kapazitätsbedarf wird der Primarratenanschluß verwendet .If the capacity requirement is very high, the primary rate connection is used.
Aus [2] oder [3] ist ein adaptives Bittransportsystem für Kupferdoppelader bekannt, das mit einem Übertragungsrahmen von n 64 kbit/s Kanälen und einem Signalisierungskanal, z.B. einem 16 kbit/s Signalisierungskanal, arbeitet. Dieses Bittransportsystem wird zwischen Teilnehmer und Netz eingesetzt. Die dadurch zusätzlich zur Verfügung stehende Kapazität kann für Datenkommunikation und/oder Sprachkommunikation verwendet werden.From [2] or [3] an adaptive bit transport system for copper twisted pair is known, which with a transmission frame of n 64 kbit / s channels and a signaling channel, e.g. a 16 kbit / s signaling channel, works. This bit transport system is used between the subscriber and the network. The additional capacity available as a result can be used for data communication and / or voice communication.
Der Erfindung liegt die Aufgabe zugrunde, eine Netzabschlußeinheit anzugeben, durch die der Anschluß mindestens eines Sprachkommunikationskanals und mindestens eines Datenkommunikationskanals an ein öffentliches Netz über eine einzige Kupferdoppelader ermöglicht wird, wobei mehrere Kommunikationen gleichzeitig durchgeführt werden können. Diese Aufgabe wird durch die Erfindung gelöst .The invention is based on the object of specifying a network termination unit by means of which the connection of at least one voice communication channel and at least one data communication channel to a public network is made possible via a single copper twin wire, wherein several communications can be carried out simultaneously. This object is achieved by the invention.
Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert .An exemplary embodiment of the invention is explained in more detail below with reference to the drawing.
Dabei wird eine geeignete Network Termination beschrieben, an die eine Nebenstellenanlage über mehrere a/b-Schnittstellen und/oder S0-Schnittstellen angeschlossen werden kann und die über eine Kupferdoppelader mit dem Netz verbunden ist.A suitable network termination is described, to which a private branch exchange can be connected via several a / b interfaces and / or S 0 interfaces and which is connected to the network via a copper pair.
FIG 2 zeigt die vorgeschlagene Network Termination. Die Nebenstellenanlage ist über m S0-Schnittstellen an den Basic Access Einheiten der Wideband Network Termination (WNT) angeschlossen. Zusätzlich stehen dem Teilnehmer noch eine oder mehrere Schnittstellen zur Datenkommunikation, z.B.2 shows the proposed network termination. The private branch exchange is connected to the Basic Access units of the Wideband Network Termination (WNT) via m S 0 interfaces. In addition, the participant has one or more interfaces for data communication, e.g.
Ethernet-Schnittstelle, zur Verfügung. In der Rahmeneinheit werden die einzelnen Verkehrstströme gemultiplext (oder konzentriert) , die Informationen in einen geeigneten Übertragungsrahmen kopiert und über die Kupferdoppelader ins Netz transportiert. Im Netz werden die von den So- Schnittstellen kommenden Informationen der Vermittlungsstelle zugeleitet .Ethernet interface, available. The individual traffic flows are multiplexed (or concentrated) in the frame unit, the information is copied into a suitable transmission frame and transported to the network via the copper twin wire. The information coming from the S o interfaces is forwarded to the exchange in the network.
Die S0-Schnittstellen können auch durch a/b-Schnittstellen ersetzt werden. Hierzu können im einfachsten Falle bestehende a/b - S0 Umsetzer verwendet werden. Prinzipiell ist auch die Umwandlung der analogen a/b-Signale in WNT-proprietäre Digitalsignale durch entsprechende a/b-Digital-Umsetzer denkbar. Die Digitalsignale werden in Zeitschlitzen auf der Kupferdoppelader zum Netz transportiert.The S 0 interfaces can also be replaced by a / b interfaces. In the simplest case, existing a / b - S 0 converters can be used for this. In principle, the conversion of the analog a / b signals into WNT-proprietary digital signals by corresponding a / b digital converters is also conceivable. The digital signals are transported to the network in time slots on the copper twin wire.
Die Erfindung bietet folgende Vorteile: • Der Netzbetreiber spart Ports an seiner Vermittlungsstelle . • Kupferdoppeladern werden frei und können für neue Anwendungen oder neue Teilnehmer verwendet werden. • Eine eventuell bei herkömmlicher Technik notwendige Neuverlegung von Kupferdoppeladern kann vermieden werden.The invention offers the following advantages: The network operator saves ports at its switching center. • Copper twisted pairs become free and can be used for new applications or new participants. • A relocation of copper twisted pairs that may be necessary with conventional technology can be avoided.
• Der Netzbetreiber muß nur noch eine Leitung betreiben, überwachen und warten (Kostenersparnis) .• The network operator only has to operate, monitor and maintain one line (cost savings).
• Der Teilnehmer kann seine Nebenstellenanlage unverändert nutzen. Die Anzahl der installlierten NTs wird kleiner. Der Teilnehmer bekommt außderdem die Möglichkeit der schnellen Datenkommunikation über die gleiche Kupferdoppelader.• The subscriber can use his private branch exchange unchanged. The number of installed NTs is getting smaller. The subscriber also has the option of fast data communication via the same copper pair.
Zukünftig ist die Integration der Nebenstellenanlage mit der WNT denkbar. Dadurch entfällt der Verkabelungsaufwand zwischen diesen Einheiten.In the future, the integration of the private branch exchange with the WNT is conceivable. This eliminates the wiring effort between these units.
