    AUTOMATIC DISTRIBUTOR AND METHOD FOR USING THE SAME
    The invention relates to a telecommunication equipment. More specifically, the invention relates to an automatic dispatcher and a method for using the same.
    CONTEXT
    Telecommunication cabinets are often used to house connection cables, cabling, and so on. used for communications from a central office, and for distribution to subscribers near the cabinet.
    Operators may encounter problems when the capacity of the cabinet is not sufficient to meet the growing demands of subscriber services.
    [0004] Another problem that often occurs is the need that may occur to reconfigure a cabinet.
    In fact, it will be understood that in one embodiment, the outer cabinet can be viewed as a matrix with subscriber pairs on one side and office equipment ports on the other.
    The matrix is configured such that any subscriber pair is physically connected to one of the plurality of office equipment ports.
    The matrix can be reconfigured, for example, if the needs of a customer change over time, p. ex. if a customer wants an upgrade or wants additional services.
    In one embodiment, the reconfiguration of the matrix requires intervention of the operator to physically change the configuration.
    A disadvantage is that fees are incurred by the physical change of the configuration.
    Another solution is to use an outdoor cabinet that is completely reconfigurable remotely. This solution may be ideal for reducing the costs associated with a change by removing the physical intervention of an operator in the field, but the skilled person will understand that this solution has the disadvantage of being expensive to implement.
    Therefore, there is need for an automatic distributor and a method for using it that overcome the disadvantage identified above.
    The characteristics of the invention appear from the description, drawings and description of the invention below.

    This being so, the present invention relates to an automatic distributor and a method for using it.
    An embodiment of a system 10 in which an Automated Distribution Frame (ADF) 12 is used as shown in FIG. 1. It will be understood that the automatic distributor can be used in an outdoor cabinet.
    As will be explained below, it will be understood that an automatic distributor comprises an overflow device and a plurality of switching matrices. Each switching matrix comprises a corresponding plurality of inputs and a corresponding plurality of outputs. A first part of the corresponding plurality of inputs is connected to the overflow device and a second part of the corresponding plurality of inputs of the switching matrix is connected to at least one corresponding subscriber loop of the plurality of loops. subscriber. A first portion of the corresponding plurality of outputs of the switching matrix is connected to the overflow device while a second portion of the corresponding plurality of output of the switching matrix is connected to at least one selected office equipment line. of the plurality of office equipment lines. Further, it will be understood that the overflow device is used to forward the traffic of a given switching matrix to at least one other switching matrix if a number of services requested by clients of the plurality of subscriber loops exceeds one number of services of the plurality of office equipment lines available in the given switching matrix.
    [00066] FIG. 1 shows a configuration in which an automatic dispatcher is used. It will be appreciated that in this configuration, a plurality of subscriber loops, also referred to as pairs, are connected to an automatic dispatcher 12. Specifically, six hundred (600) subscriber pairs are connected to the automatic dispatcher 12. It will be understood that various alternative embodiments may be provided for the number of subscriber pairs.
    It will be understood that distribution equipment is also connected to the automatic distributor 12 in this embodiment.
    It will be further understood that, in this embodiment, the subscriber pairs can be used to connect a maximum of one hundred and ninety-two (192) active users. It will be understood that the usual number of users in such an application is, on average, only one hundred forty four (144) users (ie a utilization rate of 24%).
    [00069] FIG. 2 shows a first embodiment of the automatic distributor 1 2.
    In this embodiment, the automatic dispatcher 1 2 includes an overflow device which is an overflow switch (OS) 20. The overflow switch 20 has a plurality of inputs 22 and a plurality of outputs 24.
    The automatic distributor 12 further comprises a plurality of switching matrices 26. The switching matrices are also called lower funnel switches because the number of outputs is less than the number of inputs. For example, the plurality of switching matrices 26 comprises the switching matrix 28, the switching matrix 30 and the switching matrix 32.
    In one embodiment, the plurality of switching matrices 26 comprises twelve (1 2) switching matrices.
    It will be understood that each switching matrix of the plurality of switching matrices 26 comprises a corresponding plurality of inputs, such as for example the plurality of inputs 34 of the switching matrix 38, and a corresponding plurality of outputs, as for example the plurality of outputs 36 of the switching matrix 28.
    In addition, it will be understood that, for each switching matrix, a first part of the corresponding plurality of inputs, such as for example the first part 38 of the corresponding plurality of inputs 34, is connected to a corresponding part. 40 of the plurality of inputs 22 of the overflow switch 20, and a second portion 42 of the corresponding plurality of inputs 34 of the switching matrix 28 is connected to at least one corresponding subscriber loop of the plurality of control loops. 'subscriber.
    In the embodiment shown in FIG. 2, fifty (50) subscriber loops are connected to each switching matrix. Also in this embodiment, sixteen (16) office equipment ports are connected to each switch fabric. Such a configuration therefore allows sixteen (16) services to be connected to fifty (50) subscribers.
    A first part of the corresponding plurality of outputs, such as for example the first portion 44 of the corresponding plurality of outputs 36 of the switching matrix 28, is connected to a corresponding portion 46 of the plurality of outputs 24 of the switch overflow 20, while a second portion of the corresponding plurality of outputs, such as the second portion 48 of the corresponding plurality of outputs 36 of the switching matrix 26, is connected to at least one line of selected office equipment. of the plurality of office equipment lines.
    It will be understood that in the case where more than sixteen (16) services are requested from the same group of fifty (50) subscribers, up to four (4) services may be "borrowed" from another switching matrix via the overflow switch, which is a big advantage.
    [00078] FIG. 3 shows an embodiment of a matrix of connectors such as, for example, the switching matrix 28 of the plurality of switching matrices 26.
    In this embodiment, the switching matrix 28 is a three-stage closed array made of 5 x 6 base matrices which is an embodiment of a multi-stage closed array. It will be understood by those skilled in the art that various alternative embodiments may be proposed for the switching matrix 28.
    It will be understood that, in this embodiment, a subscriber port is not used. Those skilled in the art will understand that this is usual with the use of a single basic matrix.
    The first stage 50 and the last stage 54 of the switching matrix 28 exceed the middle stage 52 by 20%. Those skilled in the art will understand that this is designed to ensure the non-blocking nature of each switching matrix by allowing its reconfiguration, if necessary, without signal interruption.
    It will be further understood that at the middle stage 52, an additional port on each side is marked TA (Test Access = test access). This additional port is a test access entry point. It will be understood that this is an embodiment of the case where a central stage, such as the middle stage 52, has at least one port for testing a connection between a given loop of the plurality of subscriber loops and a given line of the plurality of office equipment lines. At the middle stage 52, a connection of a service to a subscriber may be interrupted and reestablished on the test access equipment.
    Those skilled in the art will understand that, although the basic matrices are represented with ports on the left and right sides, the basic matrices are actually made of rows and columns with peak and annular relays to each junction. In one embodiment, all 5 x 6 base matrices are identical. Also in one embodiment, a 1 2 x 5 switching matrix is created by juxtaposing two 6 x 5 basic matrices.
    Due to the funnel architecture, only eleven (11) base dies are required on the subscriber side while four (4) base dies are located on the office equipment side.
    It will be understood that the twelfth row of each base matrix of the middle stage 52 allows, in one embodiment, an access connection to any one of the four (4) equipment line connections. office that can cross this basic matrix. The fifth column of a base matrix of the middle stage 52 allows the connection to four (4) subscriber connections among the eleven (11).
    It will be understood that such an arrangement allows the interruption of a given pair to be tested. The two sides of the data pair are referred to as "Desktop Equipment Line Direction" and "Subscriber Direction". Both sides of the given pair being tested are available on the test access pair. This given pair is combined in the funnel with two (2) other test access pairs of the funnel middle stage to create the even or odd test access pair of a funnel card.
    As shown in FIG. 4, two Test Access Ports (TAP) are connected in each switch matrix. A test access port is connected by the three (3) odd middle stages and the second test access port by the three (3) even middle stages. This allows up to two simultaneous tests on a switching matrix, provided that the two connections do not pass through a median floor of the same parity, for example a cross-talk measurement between two subscribers, a peer and an odd, and two lines of office equipment, a par and an odd, on the same funnel card. If the two desired connections share a median floor of the same parity, the connections of the switching matrix will be re-arranged automatically, without user intervention, to place one of the connections on a median floor of different parity.
    [00088] FIG. 5 shows a funnel module communication and control card 60. The funnel module communication and control board 60 includes an "any-to-any" multiplexer of sixteen (16) by four (4) used to reduce the amount wiring between the funnel module and the overflow switch and the test access equipment.
    It will be understood that all the test access ports leaving the communication and funnel module control card 60 can come from the same funnel card or any combination of four (4) funnel cards in a embodiment.
    Any combination of test access ports of the funnel cards can be made available on the funnel module test access.
    [00091] FIG. Figure 6 shows a test port access path through funnel and common equipment modules (Common Equipment = CE).
    It will be understood that a test access port offers the ability to connect the circuit under test to an external test unit.
    The test access port provides the ability to split a circuit under test. A division consists in breaking the transmission path of the circuit to be tested. The two sides, or directions, of access points are called "direction of office equipment" and "direction of subscribers".
    It will be understood that all test access ports (TAP) on the overflow switch can test test pairs that come from the same funnel module or any combination of the three (3) funnel modules.
    In one embodiment, any combination of test access from the funnel module can be made on the test access port.
    It will be understood that it is possible to access individually any subscriber line as well as any line of office equipment.
    [00097] In addition, in one embodiment, the four (4) test access ports may be used simultaneously.
    Those skilled in the art will understand that certain test functions, such as the cross-talk mapping of the automatic splitter, can be automated by software using menus or scripts.
    [00099] FIG. 7 shows an embodiment of an overflow device which is overflow switch 20. As will be explained below, it will be understood that various alternative embodiments of the overflow device may be provided.
    The overflow switch 20 used to route services from one switch fabric to another is, in one embodiment, a three-stage 48 x 48 closed network device which is an embodiment of the invention. a multi-storey closed network.
    [000101] Still in this embodiment, the overflow switch 20 consists of forty four (44) 5 x 6 switching matrices.
    [000102] More precisely, a central stage uses four (4) switching matrices of 5 × 6 to create a switching matrix of 10 × 10. Here again, as in the funnel structure, a reserve of 20% is available. a reconfiguration is necessary. It will be understood by those skilled in the art that various alternative embodiments may be possible for the overflow switch 20.
    In one embodiment, the automatic dispatcher is initially deployed with a 75% port load, one hundred and forty four (144) input side customers regularly distributed across all funnel cards. As a result, each funnel has twelve (12) input ports taken. The remaining four (4) ports provide a reserve for new connections.
    [000104] It will be understood that as the utilization rate increases and service changes occur over time, the risk of congestion on the input side increases. Those skilled in the art will understand that when this occurs, the remaining four (4) ports of the funnel are available and offer - as a temporary solution - additional routing capability through the overflow switch.
    Those skilled in the art will understand that with the automatic dispatcher embodiment disclosed herein, the disentangling can be advantageously performed with a minimum amount of handling and service interruption, simply by reconfiguring the port mapping. the automatic dispatcher and exchanging one of the five (5) subscriber connectors of the entangled funnel for one less used on another funnel.
    [000106] FIG. 15 shows an embodiment of a method for using an automatic dispatcher.
    [000107] According to the process step 1500, an automatic dispatcher is provided. This automatic dispatcher serves to connect a plurality of subscriber loops to a plurality of lines of office equipment. The automatic dispatcher includes an overflow device having a plurality of inputs and a plurality of outputs, and a plurality of switch fabric, each switching matrix comprising a corresponding plurality of inputs and a corresponding plurality of outputs. A first part of the corresponding plurality of inputs is connected to the overflow device and a second part of the corresponding plurality of inputs of the switching matrix is connected to at least one corresponding subscriber loop of the plurality of loops. subscriber, and a first portion of the corresponding plurality of outputs of the switching matrix is connected to the overflow device while a second portion of the corresponding plurality of outputs of the switching matrix is connected to at least one equipment line. desktop selected from the plurality of office equipment lines.
    The overflow device is used to forward the traffic of a given switching matrix to at least one other switching matrix if a number of services requested by clients exceeds a number of services available in the given switching matrix.
    [000108] According to the process step 1 502, a reconfiguration of the mapping of the automatic splitter is performed.
    [000109] Before performing a disentangling, it will be understood that the reconfiguration of the mapping of the automatic splitter can be performed according to various embodiments.
    [000110] According to the process step 1504, the disentangling is performed on the automatic dispatcher. It will be understood that, in one embodiment, the disentangling is performed by the operator. Thanks to the architecture of the automatic splitter, detangling is done quickly.
    [000111] According to the process step 1506, a reconfiguration of the mapping of the automatic splitter is performed after the disentangling of the automatic splitter.
    An example of a disentangling operation in a funnel module is shown in FIGS. 8A and 8B.
    For example, as shown in FIG. 8A, all the input ports, including the four (4) overflow ports, of the funnel card # 1 80 are used. The distribution of subscribers is as follows: six (6) subscribers on cable # 1, five (5) subscribers on # 2 cable and three (3) subscribers on each of the remaining three (3) cables, for a total of twenty (20) subscribers.
    [000114] Still in this embodiment, the funnel card No. 3 82 has only five (5) subscribers: three (3) subscribers on the second cable and one (1) subscriber on each of the last two (2) cables, for a total of five (5) subscribers.
    Those skilled in the art will understand that it is possible, after the reconfiguration of the network of the automatic distributor, to unravel the funnel No. 1 by exchanging the first two (2) cables funnel cards No. 1 80 and 3 82.
    The new distribution of subscribers will be as follows: twelve (12) subscribers on the funnel card No. l 80, three (3) subscribers out of four (4) of the five (5) cables, and thirteen (1 3) subscribers on the funnel card # 3 82, six (6) subscribers on the # 1 cable, five (5) subscribers on the # 2 cable and one (1) subscriber on each of the last two (2) cables.

    [000118] FIG. 9A shows an embodiment of the funnel card 90.
    [000119] In one embodiment, the funnel card 90 contains nine (9) relay cards, making a total of eight hundred and ten (810) relays.
    [000120] It will be understood that each relay card is configurable individually.
    [000121] The interconnections between each relay card create a complete funnel structure as described above.
    [000122] The fifty (50) subscriber connections are accessible from the front panel via five (5) subscriber connectors for the 5-10 model [five (5) cables of ten (10) pairs] or two (2) ) Subscriber connectors for the 2-25 model [two (2) twenty-five (25) pair cables].
    The sixteen (16) office equipment connections are accessible from the front panel via at least one (1) office equipment connector.
    [000124] The four (4) additional ports on each side of the switching matrix - subscribers and office equipment - are provided for the overflow switch module. They are connected to the backplane connector.
    The four (4) test access ports (Test Access = TA) are provided for test access, two (2) output / input pairs (odd and even). They are connected to the backplane connector.
    The funnel card 90 houses the secondary protection for subscriber connections.
    [000127] A backplane connector contains all the signals necessary for the proper functioning and management of the connections, namely power source, control signal, overflow switch signals and test access signals.
    It will be understood that, in one embodiment, the funnel module can be equipped with a maximum of four (4) funnel cards.
