Description

Description of the invention

The present invention relates to electrical filter systems for broadband remote 2 communication equipment.

To ensure high-speed data transmission, for example, in an asynchronous digital subscriber line (DSL) or in conventional digital subscriber line systems (x-DSL), it is necessary to combine and separate the voice signal sent from the switch and the high-speed x-DSL data signal at various stages , which arrived from the access multiplexer of the digital subscriber line (MDCL). This combination and separation of voice signals 70 and data signals is accomplished by a filter (sometimes called a splitter) that sums or separates these signals on their way to or from the subscriber.

A filter for combining or separating voice signals and high-speed data signals is often mounted together with the MDSCAL. Due to the high cost of the combined equipment of the MDCAL and the filter and the double wiring that must be mounted between the MDCAL and the intermediate switchboard, some 12 operators prefer to purchase different elements separately and place the filters and the MDCAL in different cells. As a rule, boards with many filters are used, that is, for several lines or accesses. These boards have the disadvantage that when one of the lines fails, the entire board must be replaced, which means high ongoing maintenance costs and disruption of all lines on that board.

The task of this invention is to create a more convenient connection scheme or configuration of broadband connections, in which the filters are placed separately from the MDCAL, but not in separate cells, as in known systems.

According to the present invention, the filters are placed on the intermediate switchboard, from which the combined signals combining speech signals and data signals pass to and from the vertical connecting block. The terms "intermediate switching board" and "vertical connecting block" are well known to specialists in the field of telecommunications technology. In a preferred embodiment, a separate filter is provided for the use of each respective individual line or access, which facilitates ongoing maintenance, reduces the cost of (9) it and does not significantly increase the space it occupies on the intermediate switchboard. It is also preferable that the design characteristics of the filters and with "connecting blocks of the intermediate switchboard have been improved in order to make better use of said space and create a manual access point. In addition, it is better that each of the individual filters has its own means of protection against overvoltages and overcurrents. o

The wiring diagram proposed by the present invention with electrical filters for broadband U connections thus has advantages compared to the known system described in the FRG utility model patent 20104605, in which such a diagram provides a connection block with upper and lower covers, which both c are intended for the routing of wires and have two rows of pairs of contacts located frontally, 10 pairs per row. Gee!

On the inside of this assembly is a filter board that carries all the filters, four in total, for the 3 or four lines that can be connected. The connection block has a number of pairs of contacts arranged on it in two rows of 10 pairs of contacts per row, some of these pairs being used for grounding

It has two pairs of contacts per line through which the combined signal passes.

The circuit diagram described in |patent 20104605) has several disadvantages. The board with the filters is "inside the connection block, so in the event of a line failure that requires a filter replacement, with the 740 you have to open the connection block to get to the board, which is inconvenient. In addition, the fact that this single c board carries filters of several lines means that together with the faulty filter, all the c" working ones must be replaced at the same time. Moreover, the filters described in |patent 20104605) have no means of protection against overvoltages and current overloads. Another disadvantage of the circuit diagram described in (patent 201046051) is that its connection block does not allow for optimal use of space, since the available mentioned 10 pairs of contacts can connect only four lines in total.

The configuration proposed by this invention allows you to get rid of several or all of the above-mentioned (se) disadvantages. The equipment according to the invention can be placed in such a way that it will make it possible to connect a total of 5 lines to the connecting block on the intermediate switchboard; and/"or leave one or more o pairs of contacts free to serve as a metal access or manual access contact to transmit this 4! 20 signal to the control stand; and/or allow filters to be individually replaced on the intermediate switchboard junction block and/or provide separate filters with means of protection against overvoltages and current overloads.

In addition, the wiring configuration of the connection blocks on the intermediate switchboard according to the proposed options, which are preferred, makes it possible to optimally use the pairs of 22 contacts and leave one half-pair of free contacts per line, which can be used for different purposes, (FI for example, they can be used for grounding or as a contact for metal access and/or connection to a control stand. This half-pair of free contacts can be connected to a control stand for the purpose of automatically monitoring the condition of the lines. In other preferred embodiments of the invention, the filters themselves may have multiple control points allowing manual access to any one of the following three 60 signals: a voice signal, a data signal, or a combined signal - a voice signal plus a data signal, in addition to the mentioned possible use of free pairs.

The distribution of pairs of contacts on the connecting block in the best version is such that in every two pairs two half-pairs are located in the upper row and the other two half-pairs are in the lower row and, accordingly, one of the upper half-pairs is used for the voice signal, and the other - for high-speed data signal x-CAL, while one of the 62 lower half-pairs is used for a combined signal - voice signal plus data signal, and the other is the above-mentioned free half-pair, which can be used for various purposes.

This distribution of the use of pairs of contacts on the connecting block of the intermediate switching board gives the maximum benefit from this block. If the number of pairs of contacts on the connection block is odd, it is possible

It is advantageous to supplement with an adjacent connecting block having the same odd number of pairs, and each pair interacts with the pair just opposite on the adjacent connecting block. Further, by way of illustration and not limitation, specific embodiments of the present invention will be described with reference to the accompanying drawings, wherein:

Fig. 1 - traditional known configuration for x-CAL networks. 70 Fig. 2 - a connecting block and a filter proposed by this invention.

Fig. 3 - the connecting block of the intermediate switchboard.

Fig. 4 - configuration of broadband networks with filters proposed by this invention.

Fig. 5 - a possible implementation of a multi-filter module.

Fig. 6 is an assembly in which, thanks to the metal access block, there is access to voice signals, data signals and 7/5 Combined signals and it is possible to use free pairs for subsequent automatic control of the latter.

In the known device shown in Fig. 1, a voice signal (2) is sent from the switch (1A), which reaches the horizontal connecting block (3) and continues to the intermediate switching board (5) through the voice jumper (4), continues makes its way further along the cable (b) until it enters the filter (9), which serves to combine or separate the voice signal (2) and the high-speed signal (8) of the x-CAL, which comes from the Digital Subscriber Line Access Multiplexer (DCL) (7) from the network, while receiving a combined signal (10), which is again fed to the intermediate switching board (5) and which then continues its way to the vertical connecting block (12) through the jumper (11). From this vertical connecting block (12), the combined signal passes through a filter (13) in which the voice signal is separated from the high-speed data signal x-CAL, and ends its path either in the telephone set (14) or in the computer ( 15). It can be seen that the filter (9) is a node remote from the intermediate switchboard (5).

According to the present invention and in order to achieve an arrangement in which the filter (9) is placed separately from i)

MDCAL (7) and in a special way, which makes it possible to eliminate the shortcomings inherent in known configurations, filters and wiring diagrams were developed. connecting blocks located on the intermediate switchboard, which are shown in fig. switchboard and which has a number of contacts (17.1) located in such a way that they enter the holes of the pairs that correspond to the voice signal, the combined signal - with the voice signal plus the data signal, the data signal and ensures the use of the previously mentioned free pairs. On the inner side of these filters are the means necessary to protect them from overvoltages and current overloads. Me

Figure 3 shows the arrangement of pairs of contacts on the connecting block (16) of the intermediate switchboard M (5) for the most profitable use of pairs of contacts of the connecting block (16). These pairs are placed in two rows, each with 10 half-pairs of contacts, to use two half-pairs of the upper row and two opposite half-pairs of the lower row for the same line. For example, half-pairs (18) and (19) are used, respectively, for a voice signal and a high-speed data signal x-CAL. At the bottom and just opposite is the "Half-pair (20) intended for the combined signal - voice signal plus data signal, while the half-pair (21) with c is free for other purposes, for example, to serve as a grounding point, or a metal access point, from where this signal can be transmitted to a control stand to automatically check the condition of the lines. ;" Figure 4 shows a configuration in which the filter or divider (9) is installed separately from the MDCAL (7), and the filter or divider (9) is directly connected to the connecting block (16). Again it can be seen that the connection block (16) is mounted on the intermediate switchboard (5), the latter having a row of -I connection blocks (16) having one or more groups of four pairs of contacts, each group has one free pair (21), one pair for cables for the input voice signal (18), another pair for cables and, for the input signal (19), data x-CAL and another pair of contacts for cables for the output combined signal. In addition, the filters (17) include several control points (17.2) with which it is possible to manually access any of the three aforementioned signals: voice, combined - voice signal plus data signal and data signal, as well as for other possible use of said free pair. In order to be able to use the mentioned free half-pair as a metal access leading to the control stand, it is necessary that the contacts on the connection block are in a certain state, that is, the contacts for the voice signals and the combined signal must be normally closed, and the contacts for the data signal must be normally open, and all this is to prevent a short circuit when pulling out the filters. This arrangement makes it possible to optimally use all the pairs located on the connecting block

F) (16), and in the case of an odd number of pairs, group each half-pair with the corresponding half-pair of the adjacent co-connecting block.

It should be noted that, although the use of individual filters is described, the same arrangement can be achieved using multi-filter modules, that is, equipment grouping filters corresponding to several lines, as shown in Fig. 5, in which the multi-filter module (22) has a row of contacts (22.1) and several control points (22.2), which allows manual access to any of the above-mentioned three signals, namely: a voice signal, a combined signal - a data signal plus a voice signal, or a data signal, and other possible using free steam. 65 Fig. b6 shows how the metal access block (23) can be used to receive a voice signal, a combined signal and a data signal, as well as implement the possible use of a free pair of contacts and,

thus making it possible to transmit these signals to the control board where they are checked automatically. The contacts (24) of the metal access block are inserted into the control points (17.2) that the filters (17) have. The drawing also shows the contacts (17 1) of the filters (17), which are connected to the connecting blocks (16).

In addition, the present invention includes improvements in equipment with electrical filters for broadband connections, filters designed for these means, as well as connecting blocks, also specially designed for connection with such filters. The purpose of the proposed additional improvements is to create the possibility of using pairs on adjacent connection blocks instead of pairs on the same connection block, preserving the functionality of the mentioned means, but greatly simplifying the wiring of the connection blocks, 7/0 while voice (ordinary telephone system) remains connected to the line when the filter is removed.

In the systems described above, among other characteristics, it is provided that the distribution of pairs of contacts on the connecting block of the intermediate switchboard is determined by two rows, of which two pairs of the upper row and two placed opposite the pairs of the lower row are intended for one line, so that the first two pairs are used, respectively, for input voice signal and input high-speed data signal x-CAL, 7/5 While one of the other two pairs is used for the output combined signal - voice signal plus data signal, and the second remains free for various purposes, for example, for grounding, or as a point metal access, from where the signal can be transmitted to the control stand for automatic checking of the condition of the lines

Such a scheme, although it reduces costs due to the separation of the multiplexer, or MDCAL, from the filters, however, causes certain difficulties with wiring, since it is necessary to alternately change pairs of contacts of one type or another 2o In the entire connection block, while the wiring could be would make it simpler if all parts of each line of the connecting block were of the same type.

The proposed additional improvements consist in the use on the intermediate switchboard of parallel connecting blocks, grouped in pairs so that within a certain pair of connecting blocks, on one of them for the incoming voice signal of the corresponding lines, one of the rows of pairs of contacts is diverted, for the outgoing of the combined signal - the voice signal plus the data signal of each line lead to the second row, and on the second connection block, opposite the first, the pairs of contacts of one of its rows are taken for the input i) high-speed data signal x-CAL, while the pairs of contacts of its second row are left free for grounding or as a metal access point or for other auxiliary purposes. This means that the pins of each filter, instead of being coplanar, can be arranged in parallel, at a distance corresponding to the distance between the connection blocks when fixed on the intermediate switchboard.

Next, as an example, the preferred placement option will be described with reference to the accompanying drawings p

Fig. 7 is a schematic front view of the connecting blocks with the proposed additional improvements, on which one of the individual filters corresponding to a single line is applied. Me)

Fig. 8 is a perspective view of one of the separate filters for introduction into any of the lines, installed M in a pair of connecting blocks of Fig. 7.

Fig. 9 is a schematic perspective view of an intermediate switchboard with connecting blocks and one of the filters.

The drawings show that the connecting blocks (1), which are part of the intermediate switching board (2), are placed parallel to each other and grouped in pairs, as shown in Fig. 7. This makes it possible to functionally combine both with connecting blocks (1-1) belonging to one pair, installing on each of them the first is a number of pairs of contacts (5), (53, (573, ... (5 V, used, for example, for the input voice signal of the corresponding ," lines, and the second longitudinal row of pairs of contacts (6), (6), (67), (6 V, used, for example, for the output combined signal - voice signal plus data signal At the same time on the second connection block (D) install the first row of pairs of contacts (3), (33, (37, ... (3 "), used, for example, for the input high-speed data signal of the x-CAL, and, finally, the second row of pairs of contacts ( 4), (4, (4"), .. (47) can be left free, for example, for grounding or as a metal access point from which the signal can be transmitted to the control stand for cars omatic line condition check This means that all connections in contact pairs (5) are o identical, according to different lines, this also applies to contact pairs (6), contact pairs (3) and c 20 contact pairs (4), at the same time, all the lines are independent, which greatly facilitates the installation of wiring. With this arrangement of the connecting blocks (1-1), each filter (7) can be simultaneously installed on two parallel connecting blocks (1-13), which is specifically shown in Fig. 8, for which the pins (8) of the filter, each of which has two contacts (9), as in Fig. 8, or three contacts, as in Fig. 9, are made parallel, so that one of them is inserted as a plug between the contacts ( 5) and (6) of one of the connecting blocks (13, and the second - between pairs of 2o contacts (3) and (4) of another connecting block (1), which is also visible in Fig. 9.

GF) For specialists in this field, the scope of this invention and its advantages are obvious, so there is no need for a detailed description. Materials, shape, size and location of structural elements can be changed, provided that this does not change the essence of this invention.
