For example the German federal post office adopt integrated data net (IDN) thus provide a kind of in digital technology the transmission data with the irrelevant net of telephone network, a kind of like this net for example is the Datex-P net.Remove outside this IDN, it is known also also having other to utilize the data network of digital transmission technology.As the representative of all these nets, below only consider IDN.
Can connect data terminal equipment (DEE) at user side on this IDN, their transmission rate can be different on the interface that is provided calmly.The data network terminal equipment (DNG) that for example known interface * 21 a kind of and according to CCITT are connected with peak transfer rate 19.2Kbit/s.Similarly also known have for example equipment of 64kbit/s of higher transmission rates.A kind of like this equipment for example is one and directly exhales network termination equipment (DAG), for the signal that makes DEE can transmit in an IDN, in the known technology, between the two, connected a data network termination equipment (DNAE), it is with the signal that the signal processing of DEE becomes can transmit, and a DNAE for example can be a DNG or DAG.
In order to make full use of the copper conductor of existing cable facility more, above-mentioned German journals " net " is also known, and for example two users only are connected to one with their telephone set and connect on the lead.The transmission of signal for example realizes between telephone office and user with transmission rate 144Kbit/s later in digitlization.These two digitized language passages respectively are by a two-conductor line transmission between user and the telephone office or rightabout ground in the passage of 64Kbit/s at two.Remaining so-called D passage is to transmit by a two-conductor line in the passage of 16Kbit/s.Remaining so-called D passage is used to control purpose with the speed of 16Kbit/s.Also can connect teleprinter at customer-side and replace telephone set.This corresponding system represents with PCM2A, because connect side and have two analog interfaces available in telephone office's side the user.
Described these two systems thereby utilize two separated net work.When a user wants to reach these two nets of " simulation " equipment utilization with his " numeral ", then he will be connected with two nets of separated path and this with known technology.This need be than higher cost, because must lay separated lead between a telephone office or a plurality of telephone office and user.
Task of the present invention is the described method of beginning is improved further, so that a user's loom only not only may but also can be connected with telephone network with integrated data net IDN through a two-conductor line.
This task will solve in this wise according to the present invention:
--the two-wire interface of two connection devices at least respectively has one to make digital interface;
--the digital interface at user side is such configuration: has the data terminal equipment that numeral inputs or outputs end and connected under the data network termination equipment situation and can connect by a two-conductor line in the centre, and
--on the digital interface of telephone office's side, connect a data network.
Utilize this method just can make this known transmission system promptly wherein the language passage between user of communication network and telephone office after the digitlization, on both direction by a two-conductor line system for transmitting, utilize simple mode additionally to be used to connect to have the data equipment that numeral inputs or outputs end.In each connection device of user and telephone office, have at least an analog interface to be replaced by a digital two-wire interface for this reason so that the two-conductor line of introducing to DNAE one of user side, and the integrated data net IDN in telephone office can be directly be connected with separately digital two-wire interface.All looms of a user can be connected with IDN or communication network by existing two-conductor line thus, and whether have the end that an inputs or outputs numeral or a simulation with them have nothing to do.The cost that is used for this method has reduced, because only be that an A/D converter must be replaced by a digital matching component in two connection devices with the simplest execution mode.Connect owing to be used for two-conductor line, additional advantage just be provided in the structure of the digital two-wire interface of user side: promptly can beguine between connection device and DNAE according to the bigger distance of situation transmission of X-or the V-interface of CCITT.Owing to use two-conductor line, the intersection line substantially simplified.
In a preferential form of implementation, in two connection devices, reach the transmission unit (UEI) that in DNAE, has inserted a use ISDN transmission method in digital two-wire interface side, by this transmission unit, the digital signal that is used for transmitting is converted and handles on two-conductor line separately or at IDN.So for example substituted A/D converter in user and the telephone office's connection device with a UEI.
The method according to this invention will be described further by means of the accompanying drawing as embodiment.
