Abstract

A process for designing a telecommunications and data network allows telecommunications and data lines to be connected to subscribers in a variable manner. The number of cable leads required for each subscriber is stripped and the uninsulated cable leads are connected to the connection of the subscribers, while other intact cable leads are led through the distributor to the other distributors for other connections and are stripped there. The object of the invention is to develop a process of said type which allows a flexible extension of the distributor for connection to other services by using available cable lead lengths in a variable manner. To that effect, a previously determined number of cable leads DA 81 to DA 100 for the variable supply of subscriber stations TN 1 to TN n are extended with additional connections EA 1 to EA n to an automatic distributor at the end of the cable (1), through which, if required, they are led back and connected to the corresponding subscriber stations TN 1 to TN n by means of the cable leads DA
1 to DA 80 separated when the cables were stripped.

Description

97-023 DE 20 August 1997 KRONE AKTIENGESELLSCHAFT, Beeskowdamm 3-11 14167 Berlin ________________________________________________________ Method for designing a telecommunications and data network The invention relates to a method for designing a telecommunications and data network according to the precharacterizing clause of Claim 1.
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 capability and: future reliability of this network configuration is inadequate to allow subsequently required services to be covered at any time, at the subscribers. The requirements for flexibility, upgrade capability. and performance of the network are provided only to an inadequate extent.
The invention is based on the object of develo-ping a method of this generic type for designing a telecommunications and data network which ensures that variable use of existing cable conductor lengths allows the handover points (distributors) to be expanded flexibly for the connection of other services.
This object is achieved by the features of Claim 1. The use of an automatic distributor at the respective cable end and its connection to spare cable conductors in the cable as well as to the cut cable conductors (resi-dual cable lengths) result in variable and flexible implementation of additional connections for the sub-scribers. This results in no cable conductor lengths being unused.
According to a preferred embodiment, a plurality of cables are connected in an automatic distributor such that the subscriber can be connected to further connec tions 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 embodi-ment of a network configuration which is illustrated in the drawings, in which:
Fig. 1 shows a schematic illustration of a net-work according to the prior art, and Fig. 2 shows a schematic illustration of the network configuration according to Fig. 1, designed according to the inven-tion.
Fig. 1 illustrates a known, conventional network configuration. According to this, subscriber points TN 1 to TN n are connected via distributors V 1 to V n to a cable 1, which contains, for example, a hundred double conductors DA 1 to DA 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 80.
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 1, 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 to provide connections for subscriber points TN 1 to TN 4 are passed 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 80.
The double conductors DA 81 to DA 100 are passed through to the automatic distributor AV at the end of the cable 1, for a variable supply of the subscriber points TN 1 to TN n with further connections EA 1 to EA n. Using the automatic distributor AV, these double conductors DA 81 to DA 100 are connected back in a variable manner, as required, to the corresponding subscriber points TN 1 to TN n, via the double conductors EA 1 to EA 80 which are disconnected when cut, and which, according tol the prior art, were routed unused to the last distributor V
n.
A plurality of cables can also be combined in the 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 1, 2, 3 can be allocated to the subscriber points TN of the respective other cable 1, 2, 3.
