P 1OPERIF9M296-98 spal da-22/02102 -1- Method for designing a telecommunications and data network The invention relates to a method for designing a telecommunications and data network.

In local communications and data technology networks, a defined number of double conductors are allocated to each subscriber using the known cut-to-fit method, are cut out of the cable and are connected via a first distributor to the subscriber. The other double conductors are passed through the first distributor, uncut, to other distributors, where they are cut and connected for the other subscribers.

The remaining lengths of the connected double conductors are unused, as far as the cable end. Spare connections/expansions are implemented as required from already existing spare cable conductors in the cable. The expansion 15 capability and future reliability of this network configuration oooo is inadequate to allow subsequently required services to be covered at any time, at the subscribers. The requirements for g flexibility, upgrade capability and performance of the network are provided only to an inadequate extent.

20 The invention is based on the object of developing a method of this generic type for designing a telecommunications ••go and data network which ensures that variable use of existing S: cable conductor lengths allows the handover points (distributors) to be expanded flexibly for the connection of other services.

In accordance with the invention, there is provided a method for designing a telecommunications and data network for variable connection of telecommunications and data lines to subscribers, characterised in that a previously determined number of cable conductors are passed through to a distributor at an end of a cable for connection to a variable supply of dsubscriber points via connections established, as required, to 9 he corresponding subscriber points using disconnected nductors of the cable, cut at the respective subscriber d< P:'OPEWDM 9529698 sp, I.do-Z2OZ2 points and extending between the respective subscriber point and the distributor.

According to a preferred embodiment, a plurality of cables are connected in an automatic distributor such that the subscriber can be connected [lacuna] further connections from different cables. This achieves a considerable expansion in capacity.

Further advantageous refinements of the invention result from the dependent claims.

The invention will be explained in more detail in the following text with reference to an exemplary embodiment of a :network configuration which is illustrated in the drawings, in g which: Fig. 1 shows a schematic illustration of a network 15 according to the prior art, and ego Fig. 2 shows a schematic illustration of the network e configuration according to Fig. i, designed according to the l invention.

g 0 Fig. 1 illustrates a known, conventional network e o 20 configuration. According to this, subscriber points TN 1 to TN o•o n are connected via distributors V 1 to V n to a cable 1, which oooo "contains, for example, a hundred double conductors DA 1 to DA S 0: 100.

The subscriber point TN 1 is connected to the double conductors DA 1 to DA 4, the subscriber point TN 2 to the double conductors DA 5 to DA 10, the subscriber point TN 3 to the double conductors DA 11 to DA 15, the subscriber point TN 4 to the double conductors DA 16 to DA 20, the subscriber point TN n to the double conductors DA 76 to DA The double conductors DA 81 to DA 100 are passed through the distributors V 1 to V n and are used as required to implement expansion connections EA i, EA 2, EA 4, EA n by means of jumper lines (spare connection) The double conductors DA 1 to DA 20 which have been used A 35 to provide connections for subscriber points TN 1 to TN 4 are d 4, C-) P:OPER\DM93296-98 spa I do-22/02O2 -3passed on unused as spare cable lengths RKL as far as the cable end at the last distributor V n.

Fig. 2 illustrates a network configuration of a telex access network according to the invention having an automatic distributor AV.

The subscriber point TN 1 is connected to the double conductors DA 1 to DA 4, the subscriber point TN 2 to the double conductors DA 5 to DA 10, the subscriber point TN 3 to the double conductors DA 11 to DA 15, the subscriber point TN 4 to the double conductors DA 16 to DA 20, and the subscriber point TN n to the double conductors DA 76 to DA The double conductors DA 81 to DA 100 are passed through oo oo. to the automatic distributor AV at the end of the cable i, for a variable supply of the subscriber points TN 1 to TN n with 15 further connections EA 1 to EA n. Using the automatic •co distributor AV, these double conductors DA 81 to DA 100 are e connected back in a variable manner, as required, to the corresponding subscriber points TN 1 to TN n, via the double o• 0conductors EA 1 to EA 80 which are disconnected when cut, and 20 which, according to the prior art, were routed unused to the last distributor V n.

oooo :A plurality of cables can also be combined in the o• automatic distributor AV, for example, as is illustrated in Fig. 2, the cables 1, 2, 3. This achieves even greater flexibility in that the variable conductors in the cables i, 2, 3 can be allocated to the subscriber points TN of the respective other cable i, 2, 3.

The reference to any prior art in this specification is not, and should not be taken as, an acknowledgment or any form of suggestion that that prior art forms part of the common general knowledge in Australia.
