Description

CENTRALIZED OPERATION AND CONSERVATION STRUCTURE APPLICABLE TO A TELEPHONE PLANT D E S C R I P C I O N OBJECT OF THE INVENTION The present specification refers to a patent application of invention relating to a centralized operation and conservation structure applicable in a telephone plant, whose purpose is to consider the different existing equipment and operating systems integrated in a single structure configured as the Architecture of Operation and Conservation of the Telephone Network, architecture developed by the applicant and that includes a hierarchical system (SOC-Sis emas Control-Terminal Plant), integrating the supervision of different types of telephone plant. ca through a common interface, existing a parallel network of security and counting on the relevant interconnection of the different elements of the structure, through the integration of X.25, TCP \ IP and asynchronous networks with two different proprietary protocols.

It should be noted that the invention also contemplates the action on a connection to the SERES, structure of connections between the Provincial SOC and the different control systems and existing main plant terminals, as well as the internal structure of the SOC, redundant control of different terminals, interchangeability of the SCS, incorporation of audio facilities for various systems and supervision of power stations in which the MORE has been installed, configured by a digital control unit for electromechanical power stations, which was originally requested as an invention patent in Spain on behalf of Telephone of Spain.

FIELD OF THE INVENTION This invention has its application within the field of telecommunications, and in particular, in the systems for the operation and maintenance of telephone networks.

BACKGROUND OF THE INVENTION The traditional conservation / operation procedures of the Basic Telephone Network are characterized by their repetitive schemes of applying the same procedure to a multitude of Scattered Plant Elements, by the manual execution of tasks and in general by the need for coordination between activities of the working groups, using a large amount of resources for all this.

These characteristics imply a lack of integration in the conservation / operation activities, playing a fundamental role the skill and ingenuity of the operators in the search of solutions to the daily problems, making their presence necessary in many points of the Network. .

In many of the problems involved elements of Switching, Transmission, Radio, Outdoor Plant and Power Plant simultaneously, resolved by constant telephone calls between operators of different Power Plants.

All this, as far as troubleshooting is concerned, and on the other hand, both in this task and in other Maintenance and Network Management services, traditional guidelines for sending printed reports, tapes and discs continue to be maintained. necessary administrative tasks that slow down the provision of customer service.

The obvious solution to the current problem in this area, would be to have a centralized Operation and Conservation Structure, which would obviate or at least reduce a plurality of operations that must be performed for the centralized maintenance of a telephone plant.

However, until now there is no knowledge on the part of the applicant of the existence of a structure of operation and conservation that allows alleviating the aforementioned problem.

DESCRIPTION OF THE INVENTION The centralized operation and conservation structure applicable in a telephone plant proposed by the invention, is configured as a set of systems to help the integrated and centralized operation of the Telephone Plant, allowing the operation and conservation of the entire analog / digital plant, Trying the Switching, Transmission, Radio Plant, Power Plant and Outdoor Plant in an integrated way.

Basically, it consists of a network superimposed on the Basic Telephone Network (RTB), with a series of Plant Terminals to which the Plant Elements of the Basic Telephone Network must be connected, so that they can be supervised.

The operation and maintenance structure receives information on the status of the plant in service, processes it and makes it available to the operator in a homogeneous, simplified and affordable format, transferring the orders of said operator to be executed remotely in the element of the corresponding plant, thus considerably facilitating its work.

In this way, the displacements for the repair of faults are considerably reduced, being limited to those faults that are strictly mechanical in nature.

The centralized Operation and Conservation Structure applicable in a Telephone Plant object of the invention is defined as a set of hierarchical Operation Systems that covers the exploitation needs of a certain geographical area, systems that integrate different switching equipment, transmission, radio, energy and in general all the elements of the telephone plant, thus allowing an integrated service of Maintenance and Operation of the Network.

As operating system, it should be understood a set of computers, not two of data switching and communication systems that provides a set of services.

Thus, the centralized Operation and Conservation Structure provides the services offered by the Operation Systems and plant terminals that compose it.

It is constituted by four main elements. Namely: I - Plant Terminals.

- Plant Control Systems.

- Control Centers.

- Media.

The plant terminals are directly related to the Elements of the Telephone Plant (switching centers, transmission equipment, radio equipment, power equipment, cable equipment, lines, etc.) and act as interfaces between said elements of the plant. plant and the rest of the elements of the Operation and Conservation Structure, providing information on the state of the Plant and providing the necessary means of action.

The range of types of Plant Terminals is very wide, covering cases in which it is only necessary to capture alarms and collect data, with few alarm points to explore, even situations where tele-government is required and a large number of exploration points.

The main plant terminals considered are the following. Namely: Multifunctional Plant Terminal (TPMF) configured as a team located in analogue switching centers that, whether served or not, need the supervision of a large number of alarms and remote and centralized government.

Rural Multifunctional Plant Terminal (TPMFR), for the supervision of local analogue switching stations.

. Terminal of Alarm Collection Plant (TPRA), small equipment that is located in rural points that will not be served, to capture the status of alarm points of the plant elements.

. Terminal Transmission Alarm Plant (TPAT), for the collection of alarms of transmission equipment.

. Transmission Measures Plant Terminal (TPMT), for the supervision of transmission equipment.

. Terminal of the Channel Concentrator Plant (TPCC), used for the concentration and switching of RS-232 channels.

. Canal Concentrator Plant Terminal Reduced (TPCCR), used for the concentration and switching of RS-232 channels in those plants with reduced connection capacity.

. Power Plant Terminal (TPE), which allows the supervision of energy equipment.

. Computer Bus Plant Terminal (TPBI), for connection to the system of transmission equipment equipped with a supervisory computer interface.

. Terminal of the Communications Interface Plant (TPIC), which allows the access of the Operation and Conservation System to the Digital Centrals.

. Fiber Optic Plant Terminal (TPFO), which has as its objective the permanent supervision of vacant or in service optical fibers.

. Other units, which can be considered as plant terminals, with respect to the Radio Plant or Cable Supervision, are the Supervision Systems of the Radio Plant (SSPR), the Remote Remote Units (UR), the Central Units (UC) and the Data Acquisition Units (UAD).

The plant control systems are responsible for the concentration of the plant terminals previously indicated, and provide the means of processing and storage of data.

The main Control Systems considered are the following. Namely: - Operation and Conservation Systems (SOC-P, SOC-M, SOC-N).

- Security Systems (SS-P, SS-M, SS-N).

- Sectorial Control System (SCS).

/ - System of Reduced Sectorial Control (SCSR).

- Sectoral Control Device for Transmission (DCST).

- Radio Sector Control Device (DCSR).

- Centralized Cable Supervision System (SSCC).

The control centers are the workplaces of the personnel responsible for the operation, through which the operators communicate with the different operating systems and therefore the peripherals of input / output of the information reside in them. say, alarm panels, graphic terminals and printers.

Also, there are some centers called Internal Maintenance Centers (CMI), in charge of managing and updating the software of the components of the Structure that is being described.

Regarding the media, it should be noted that the aforementioned elements, which, together with the latter, make up the Operation and Conservation Structure, are related to each other through the means of communication, with their corresponding standardized or specific protocols.

The centralized Operation and Conservation Structure is conceived in such a way that the supervision of the Basic Telephone Network takes place from different hierarchical levels and considering areas of different extension.

Thus, the first level that requires supervision is the plant itself, the plant being understood as the building where the RTB equipment is installed, the environment where Plant Terminals operate and which constitutes the LOCAL operation scope.

The network elements of the RTB and its terminals are grouped into Sectors, or Sectoral operating environment, where the control systems described perform their function.

The control systems, in turn, are grouped into others of higher hierarchy until reaching the highest level or national level, where the control system that brings together the entire Operation and Conservation Structure is framed.

Consequently, the hierarchical organization of the centralized Operation and Conservation Structure (EOC), from the upper level to the lower level, presents various levels: The zero level is formed by the National SOC (SOC-N) and the National Internal Maintenance Center (CMI-N). I Level one is formed by the Multi-Provincial SOC (SOC-M), Multiprovincial Security Systems (SS-M) and Muti-Provincial Internal Maintenance Centers (CMI-M).

Level two is formed by Provincial SOCs (SOC-P), Provincial Security Systems (SS-P) and Transit SOC (SOC-T).

Level three is integrated by the control systems (DCSR, DCST, SCS, SCSR) previously indicated.

Level four is integrated by the different Plant terminals (TPAT, TPMT, TPCC, TPCCR, TPMF, TPMFR, TPE, UEA, TPFO, TPRA, TPBI, SSPR, UR, UAD) referenced above.

Level five consists of the Plant Elements to be monitored (Radio, Transmission, Analog Switching, Digital Switching, Outdoor Plant, Energy).

Given the great variety of plants to be monitored, a Universal Exploitation Language (LUEX) is used, as a common language, in such a way that with the same user interface it allows different functions to be carried out regardless of the type of Plant that is being managed.

The users of the Centralized Operation and Conservation Structure are the operators that conserve the network and these are grouped forming families or working groups to which an operator belongs.

Important families can be considered the Switching, the Transmission, the Radio, the Outdoor Plant, the Power Plant, etc.

The Plant Terminals are equipment that through exploration and action points and data interfaces, are directly connected to certain elements of the Plant, such as electromechanical and semielectronic power stations, transmission equipment, power equipment, etc. ., in order to monitor its operation.

They are capable of detecting states, anomalous sequences and executing orders on the Plant Elements, to which they are connected, acting as intermediate elements between them and the Plant Control Systems.

The Multifunctional Plant Terminal (TPMF), is conceived as a team to be installed in the cross-bar electromechanical power stations, in order to monitor their behavior by analyzing the real-time status of all their relevant bodies and acting on them when necessary. necessary through the use of remote controls.

The TPMF collects information from the plant through exploration points connected to the fundamental organs of the plants.

You can also act on them through action points or remote controls, which allow the control of auxiliary equipment and the isolation of organs. I The Rural Multifunctional Plant Terminal (TPMFR) is the terminal used for the supervision of plants in rural areas.

The Terminal of the Interconnection Plant of Communications (TPIC), implements the interface function for the access from the SOC-P to the Digital Centrals.

The connection of the SOC-P and said plants is done by means of dedicated lines, using X.25.

The Alarm Collection Plant Terminal (TPRA), is a terminal similar to the TPMF, but directed to the exploration of external points of alarms, detecting any change of state in the same ones and transmitting said changes to the SCS or the SCSR.

The Transmission Alarm Plant Terminal (TPAT) is the physical element responsible for collecting the alarms from the transmission plant that are scattered as external alarm points.

They are located in the vacant space that has the Filacera Header of the transmission equipment, connecting to each other in multipun-to configuration, in such a way that only one of them (called master), is connected to the DCST.

The Plant Terminal for Transmission Measures (TPMT), is the terminal responsible for the realization of measurements on the digital transmission flows, in order to analyze the quality provided by the supervised links.

They are installed in those transmission centers that, due to their importance (important data transmission flows), require the realization of measurements.

The Concentration Plant Terminal of Channels (TPCC), is the terminal of the EOC specialized in the connection .. with the elements of intelligent Network that have an RS-232 or RS-485 link for its remote supervision.

Likewise, they can perform functions of scanning external alarm points and activating remote controls, avoiding the installation of additional plant terminals when these functions are needed.

This terminal is also used for the supervision of plants in which the Modernization of Electromechanical Power Plants (MORE) system has been installed.

It also allows the connection of (TPE).

The Terminal of the Reduced Channels Concentration Plant (TPCCR) is based on the functionalities of the TPCC, but adapted to the needs of those plants for which the TPCC connection capacity is excessive.

This terminal has a series of asynchronous doors, equipped with an internal modem to allow connections with remote plant elements that have RS-232 ports for control and operation.

The Computer Bus Plant Terminal (TPBI), allows the connection to the system of the transmission equipment equipped with supervisory computer interface.

It is responsible for the supervision, concentration and unification of protocols of equipment from different manufacturers to adapt to the needs of the EOC.

It is installed in the power stations where there are equipment equipped with a supervisory computer interface and it is connected to the DCST both directly and through a TPAT.

This allows the reception of all the monitoring information provided by the equipment, alarms and quality measures, mainly in any Control Center for the Transmission Plant.

The Optical Fiber Plant Terminal (TPFO) has as its objective the permanent supervision of vacant or in service optical fibers, in such a way that if some type of anomaly is detected by cutting or degradation of the optical characteristics of the fiber, it sends a message to the SOC Provincial to alert the operator and proceed with the repairs.

The Power Plant Terminal (TPE) is the team in charge of centralizing the supervision of all the energy equipment located in a building.

Supervision is applied to transformer stations, service switchboards, power panels, air conditioning units, battery sections, etc.

Performs the functions of supervision by means of the exploration of points of alarms and the analysis of currents and tensions continuous and alternate of the force equipment and of the air conditioning equipment, through temperature sensors distributed by the enclosure on which they act .

The Plant Control Systems are responsible for the concentration of Plant Terminals and provide the means of processing and storage of data.

The Centralized Cable Supervision System (SSCC) allows the exploitation of the Cable Plant.

It consists of a single Central Unit (for each SSCC), which controls a series of Remote Units (UR), as well as a set of Units of Acquisition of Data (UAD).

Both the Remote Units (UR) and the Units of Acquisition of Data (UAD), concentrate the information taken from the data collection points of the Cable Plant. The Radio Sector Control Device (DCSR), can be considered within the Operation and Conservation Structure, as a System of Operation and Conservation (SOC) of lower hierarchy, oriented to the Radio Plant.

To work with the Plant Elements assigned to it, it has connections with the SSPR and TPAT for the supervision of external alarm points.

The Radio Plant Supervision System (SSPR), is a network configured based on two types of basic units or stations: the Central Units (UC) that are responsible for cyclically interrogating the rest of the Units belonging to the network, processing the information collected and presenting through its visualization bodies, the most significant events that can happen to the Remote Units (UR), which are the units in charge of obtaining information on the supervised elements, of executing the actions on them and of meeting all the requirements that automatically or at the request of the operators is carried out from the UC.

The Sectorial Control System (SCS) allows the supervision and operation of analogue switching equipment located within a sector of a telephone province.

The operation of the power stations and network elements of an electromechanical nature is grouped forming said telephone sectors. I In order to carry out its mission, the SCS is connected to all the TPMF, TPMFR and TPRA Terminals corresponding to the Network Elements belonging to that sector grouping.

Therefore, its basic function is the concentration of Plant Terminals (Concentration of Communications) and the provision of Control Centers for its attention, having for it mainly a computer with the configuration and system recharge data, as well as a printer and an alarm panel.

First of all, the SCS allows the connection to the various Plant Terminals indicated by a remote presentation service and operate with them, performing the alarm treatment, the printing services, communication with the TPMF, TPMFR and TPRA of the SCS and the maintenance of the system itself.

Likewise, it incorporates audio facilities, through the use of an Audio Terminal (TAR), both as a means of communication between the Plant Control Systems, and for the realization of test calls supervised directly by the operator on the PC- 32 On the other hand, the SCS allows the routing of the information that is selected towards the SOC, (Plant Control System at the provincial level), based on criteria defined by the operators locally or remotely.

Second, the SCS to achieve operability in sectors where the constant presence of an operator is problematic, has two important mechanisms. Namely: - Sector Attention, which consists of the supervision of a SCS that does not have its own Control Center (SCS not served), from another SCS previously defined and that can be called the Service Center.

All the information that arrives at the unattended SCS is retransmitted to the Service Center, so that the operators present in it, treat said information in the established manner.

- The Sector Transfer, which can be defined as a temporary service, through which the information received in a SCS is retransmitted to SCS previously defined as the Transfer Center of the former.

The ease of transfer allows in a temporary way to serve one Sector from another, reducing the needs of personnel in locations that do not need it permanently.

From the moment the transfer command is given, the alarms, spontaneous messages and deferred responses that were directed to the SCS where the command is given, will be redirected to its Transfer Center.

Any SCS can be Transfer Center or transferable center.

The System of Reduced Sectorial Control (SCSR), allows the concentration of local and remote data channels, the supervision of alarm points, the execution of remote controls and in general, the supervision and operation of the TPMFR, TPRA, TPE and TPCC, connected to it, with a capacity more directed to a rural environment.

Likewise, it allows the interconnection of the Operation and Conservation System (SOC) with the Modernization System for Electromechanical Power Plants (MORE).

The Transmission Sector Control Device (DCST) can be considered within the EOC as a concentrator of the terminals of the transmission plant, that is, as a SOC of lower hierarchy for the Transmission Plant.

Thus, it carries out the monitoring of alarms of the TPAT and TPMT, and can also interconnect the SOC with the TPE.

The DCST is installed in transmission centers of a certain entity, in which there are maintenance personnel, being responsible for the supervision of the plant in which it is located and of other smaller plants that exist in its environment.

The Operation and Conservation System (SOC), is the system located at the highest level of the hierarchy, its main objective being the centralized exploitation of the Basic Telephone Network of a certain geographical area.

Depending on this geographic area, the EOC covers up to three different hierarchical levels: Provincial, Multiprovincial and National, areas of influence always observed from the telephone point of view.

Each SOC comprises a Control Subsystem and one \ several Control Centers themselves.

It concentrates all the information related to the exploitation of the Network.

The digital exchanges are connected directly to SOC, as are the different Operational Systems indicated above and some TPCC and TPMF.

All the information received is presented to the operators located in the different Control Centers of the SOC, providing information on the status of the Plant under their charge.

The SOC consists in the Control Centers of a panel that shows in real time the active alarms of the whole supervised plant, supporting facilities to select under different criteria such as origin, family, type of plant and time interval, the routing of the to different destinations.

Likewise, it renews the spontaneous messages received from the Elements of the Plant to the terminals of the Operators and other SOCs according to a wide range of criteria.

From the SOC, an operator can connect to and operate with the different Plant Elements, Plant Terminals or other Operating Systems such as another SOC, an SCS, a DCSR or a DCST.

For example, it allows connection to the Dispo-sitivo Sector Control Plant Radio (DCSR) in a transparent manner and act through it on the radio plant, trying all alarm information and spontaneous messages generated by the SSPR and representing the state of the Plant through a set of graphic panels that reflect the structure of the supervised Plant.

It also incorporates diverse audio facilities, some as a means of communication between EOC systems and others for the direct supervision of test calls made by its operators with rural centers.

It also allows the planning of tasks to be executed later and provides the necessary mechanisms to ensure the security of the system, limiting the actions that users can take, by defining categories and checking their access.

The Control Subsystem is composed of general-purpose computers connected to each other through a local area network.

Access to the Plant Elements is done through point-to-point data lines, or through public / private X.25 networks.

Switched line multiplexers and audio point-to-point lines are also used.

The Control Centers, at the SOC level, are the workplaces of the operators and there may be several depending on the configuration of the system, it being possible to specialize each of them in the processing of information from a geographical area or of a certain type of Plant to be monitored (Transmission, Digital Switching, Analog Switching, etc.).

The Control Centers can be local, connected by a local area network to the Control Subsystem or remote, connected to the latter by X.25 lines.

In the case of Local Control Centers, these centers are constituted by several work stations and PCs connected in a local network with the computers of the Control Subsystem, portable remote terminals equipped with a modem for access to the Control Center via RTC, as well as printers, a panel of alarms and Remote Audio Terminals (TAR) for the supervision of the rural plants of plants.

In the case of Remote Control Centers, they are connected to the Control Subsystem through X.25 lines, being constituted by several work stations and PCs, as well as the software corresponding to the assigned functionality.

These centers allow the same capacity of access to information as local centers.

The Security System (SS), is an emergency network parallel to the EOC, which replaces it when it is not operational. i 'They are replicated three hierarchical levels as in the case of the SOC, so provided, a security system Provincial level (SS- P), one Multiprovincial (SS-M) level and one at a national level (SS -N) Security Systems sometimes use the same lines to reach the elements of the plant and in the same way, sometimes they use different plant terminals.

At the Provincial level (SS-P) it presents the face-to-fall protection of the communications lines with the digital power plants and breakdowns in the Provincial SOC.

At the Multiprovincial level (SS-M) it protects against falls of communications lines of the SOC-M, with the corresponding SOC-P.

In the same way, at the National level (SS-N), the communication lines between the different SOC-M and the SOC-N are protected.

The EOC Security Network is connected to the EOC through the use of a public data network or a private exploitation network.

The terminals TPCC or TPCCR, DCST and SCSR are integrated into the emergency network.

Likewise, access to digital exchanges is allowed, for which a TPCC is installed in each digital exchange.

Regarding the different Communication Media, the Operation and Conservation Structure presents three different types of networks, that is, X.25 networks, asynchronous networks and IP networks.

TCP / IP is used for communications between the different SOCs.

The X.25 lines allow connection to the digital switching plant.

Asynchronous communications are used for the connection with the rest of the telephone plant, using two different types of protocols: the AEOC, full-duplex level 2 asynchronous protocol of the EOC (connection between SCS and the TPMFR mainly) and the N2R protocol , Asynchronous protocol level 2 rural half-duplex, used for the connection of SOCs with terminals TPBI, TPAT, TPMT and TPCC and SCSR.

The connections between the SOC and the SCSR also consist of audio facilities in addition to the use of the AEOC protocol.

The connections between the SOC and the SCSR also consist of audio facilities, in addition to the use of the N2R protocol.

With regard to the SOC itself, the connection of the computers of the Control Subsystem and of the Local Control Centers is done through a local network, while the Control Centers Remotes use X.25 lines.

The SCSR is connected to the TPMFR, TPRA, TPE and TPCC plant terminals via V.24 links for local connections and through V.21 and V.22 bis modems for remote terminals, in both cases using the Rural Level 2 protocol. .

The connection of the DCST to the TPMT and TPAT is done through V.24 links for local connections and through V.22 bis modems for the remote ones, in both cases using the Rural Level 2 protocol.

Finally, the EOC consists of a connection to SERES (System of Exploitation of Signaling Network number 7), having at all times the knowledge of the status, configuration and behavior of the signaling system number 7.

The SOC-SERES connection obtains the information from the transit digital exchanges connected to the SOC-T (Traffic SOC), and the SERES can control up to 80 of these digital transit exchanges.

In addition, this EOC-SERES connection provides the SERES with valuable information about alarms, beats and the configuration of the network in general.

The Plant Control Systems are responsible for the concentration of the Plant Terminals previously indicated, and provide the means of processing and storing data, having identified in this figure number 2, the Operation and Conservation System (SOC) itself (57 ), the Sectorial Control System (SCS) (44), the Reduced Sectorial Control System (SCSR) (43), the Transmission Sectorial Control Device (DCST) (42) and the Sectoral Radio Control Device (DCSR) ) (56).

The Sectorial Control System (SCS) (44) allows the connection to the various Plant Terminals indicated by a remote presentation service and operate with them, performing the alarm treatment, printing services, communication with the TPMF (33), TPMFR (32) and TPRA (31) of the SCS (44) and the maintenance of the system itself.

The System of Reduced Sectorial Control (SCSR) (43), allows the concentration of local data channels, the supervision of alarm points, the execution of remote controls and, in general, the supervision and operation of the TPMFR (32), TPRA ( 31), TPE (34) and TPCC (35), connected to it, with a capacity more directed to a rural environment.

The Transmission Sectorial Control Device (DCST) (42), can be considered within the EOC as a concentrator of the terminals of the transmission plant (7), that is, as a SOC of lower hierarchy for the Transmission Plant .

Thus, it performs the supervision of the TPAT (30) and TPMT (29), and can also receive alarms from a TPE (34), provided it is connected to a TPAT (30).

The DCST (42) is installed in transmission centers (7) of a certain entity in which there are maintenance personnel, being responsible for the supervision of the plant in which it is located and of other smaller plants that exist in its environment .

The Radio Sector Control Device (DCSR) (56) can be considered within the EOC as a concentrator of the terminals of the radio plant (6), that is, as a SOC of lower hierarchy for the Radio Plant (6).

The Operation and Conservation Systems (SOC) (57) are the systems located at the highest level of the hierarchy, with the main objective being the centralized operation of the Basic Telephone Network of a certain geographical area.

They comprise a Control Subsystem (11) and one / several Control Centers (12).

The architecture considers depending on the geographical area to be monitored, up to three different hierarchical levels: Provincial (SOC-P), Multiprovincial (SOC-M) and National (SOC-N), areas of influence always observed from the telephone point of view.

The SOC concentrates all the information related to the exploitation of the Network. The digital exchanges (24) are directly connected to it, as well as the different Operation Systems indicated above and some TPCC (35) and TPMF (33).

All the information received is presented to the operators located in the different Control Centers (12), providing information on the status of the Plant under their charge.

The Control Subsystem (11) is composed of general purpose computers connected to each other by means of a local area network (16).

Access to the Plant Elements is done through point-to-point data lines, or through public / private X.25 networks.

Switched line multiplexers and point-to-point audio lines are also used, all through the use of communication concentrators (17).

The Control Centers can be local (12), connected by a local area network (16) to the Control Subsystem (11) or remote (20), connected to the latter by X.25 lines (22).

In the case of Local Control Centers (12), these centers are constituted by a set of Operating terminals (14) connected in local network (16) with computers (14) of the Control Subsystem (11), portable remote terminals (19) equipped with a modem for access to the Control Center (12) via Telephone Network Switched (21), as well as print media (15) and Remote Audio Terminals (18) (TAR) connected by audio lines (49) for the supervision of the rural PC-32 plant (25).

In the case of Remote Control Centers (20), they are connected to the Control Subsystem (11) by X.25 lines (22), being constituted by several work stations and the software corresponding to the assigned functionality.

These centers allow the same capacity of access to information as local centers.

The external communications of the SOC (57) with the digital Plant Elements (24), the DCST (42), the DCSR (56) and the SSCC (38) are synchronous, following the X.25 (22) standard, while the connections with the TPMF (33) are asynchronous following a particular norm of own design called AEOC (47), incorporating in addition to this protocol for the case of the SCS the audio facility (46).

In the case of the SCSR (43), the Rural Level 2 protocol is used to communicate with the SOC (57), also incorporating audio facilities (45).

Also, for communications with the other different Plant Terminals: SSPR (39), TPAT (30), TPE (34), TPCC (35) and SCSR (43), the Rural Level 2 protocol (48) is also used.

The SCSR (43) is connected to the plant terminals TPMFR (32), TPRA (31), TPE (34) and TPCC (35) via V.24 links for local connections and modems V.21 and V.22 bis for the remote ones, in both cases using the Rural Level 2 protocol.

The connection of the DCST (42) to the TPMT (29) and TPAT (30) is done through V.24 links for local connections and through V.22 bis modems for the remote ones, in both cases using the Rural Level 2 protocol.

Likewise, the different Provincial SOCs (57) are connected via TCP / IP (51) to other SOC (57) Provincial lines.

Also, they consist of connection (50) to the SOC Multiprovincial and the National SOC.

The hierarchical structure of the SOC Provinciales (57), Multiprovinciales (58) and the National SOC (59), is contemplated in figure number 3, where the Provincial (61), Multiprovincial (60) and National security systems are also indicated. (62), such as the connection through the Traffic SOC (63) to the System of Signaling System Operation number 7 (64).

The maximum configuration of the SOC-N allows the connection of up to 12 SOC-M, while the configuration of the SOC-M allows the connection of up to 20 SOC-P, using X.25 lines point-to-point or using a data network.

The maximum provincial configuration allows up to 10 SOC-P (57) per telephone province, establishing for each SOC-P (57) up to 16 control centers (local + remote) (12 + 20) and the connection of 25 DCST (42) , 10 SSCC (43), 32 TPCC (35), 32 SCSR (44), 10 DCSR (56), 100 SCS (43) and up to 240 digital centers (24), according to the following distribution: 100 AX, 100 S12 and 40 5ESS.

Regarding the dimensioning of the SCS (44), it admits up to a total of 17 Plant Terminals, being able to support up to 3 monopose Control Centers.

In order to reduce to the maximum the probability of unavailability of the components of the systems that make up the EOC, it is necessary to create a parallel network to the EOC, to replace it, as far as possible, when it is not operational.

This security system is installed at three different levels of SOC, Provincial, Multiprovincial and National.

As can be seen in Figure 4, the EOC Security Network is connected to the EOC through the use of a public data network or a private exploitation network (65).

There are monitoring and emergency operation nodes at the provincial (SS-P) (61), multi-provincial (SS-M) (60) and national (SS-N) (62) levels.

The terminals TPCC or X.PCCK 135), DCST (42) and SCSR (43) are integrated in the emergency network 100.1.

Likewise, access to digital exchanges is allowed, for which a TPCC is installed in each digital exchange.

Finally, the EOC consists of a connection to the SERES (System of Exploitation of Signaling Network number 7), having at all times the knowledge of the status, configuration and behavior of the signaling system number 7.

The SOC-SERES connection obtains the information from the transit digital exchanges connected to the SOC-T (Transit SOC) (63), and the SERES (64) can control up to 80 of these exchanges.

In addition, this EOC-SERES connection provides the SERES with valuable information about alarms, beats and the configuration of the network in general.

It is not considered necessary to make this description more extensive so that any expert in the field understands the scope of the invention and the advantages derived therefrom.

The materials, sizes and disposition of the elements will be susceptible of variation, as long as this does not suppose an alteration to the essence of the invention.
