Abstract

The proposed utility model relates to telecommunication technology, and more specifically to synchronization equipment used to provide synchronization signals for synchronization objects. The technical result of using the utility model is the ability to perform the functions of one or several types of synchronization devices — a secondary master oscillator (VZG), a clock network signal splitter (PC TCC), a resynchronization device (URS), as well as promising and fundamentally new functions without the need for purchase and installation of additional equipment, without changing the hardware configuration of the equipment. And also it becomes possible to measure the parameters of the synchronization signals at the output of the synchronization devices (sources of synchronization signals) without breaking the connection. The technical result of the utility model is achieved through the use of a universal, programmable, configurable control module that provides the ability to remotely change the composition of logical function blocks, their relationships and software, and through the use of synchronization signals in the input field of consumers and in interface modules of inputs of plinths with normally open or normally closed contact pairs.

Description

The proposed utility model relates to telecommunication technology, and more specifically to synchronization equipment used to provide synchronization signals for synchronization objects.

Known as a prototype equipment for branching synchronization signals ARSS - ABVG, (Specifications IFPM.465275.001 TU), where ABV is the number of removable units that determine the functions of the equipment, and G-presence ("1") or absence ("0") of the field connecting consumers of the RFP (separate passive switching device). In addition to plug-in units, all equipment modifications contain permanent units: a voltage-controlled generator, input interface modules and a quality control module, data transfer interface modules and interface output modules associated with the connection field of synchronization signal consumers,

The consumer connection field provides an individual consumer connection to any of the 12 outputs of the Us-2048 unit through D-sub connectors, which do not allow measuring synchronization signal parameters without disconnecting the connection.

The purpose of this utility model is to create a synchronization device that would perform the functions of one or several types of synchronization devices, as well as more convenient during operation.

The goal is achieved through the use of a universal, fully configurable programmable control module that provides the ability to remotely change the composition of logical function blocks and their relationships, as well as software.

Also, to achieve the goal in the field of connecting consumers of synchronization signals and in the interface modules of the equipment inputs, plinths with normally open or normally closed contact pairs are used. The skirtings comply with the international requirements and standards of ISO / IEC 11801, EN 50173, EN 60352 and EIA / TIA 568.

Thus, it is proposed to introduce a universal control module based on programmable logic integrated circuits (FPGAs) into a synchronization device, including a voltage-controlled generator, input interface modules, data transfer interface modules and output interface modules connected to the field for connecting consumers of synchronization signals, in which the structure and interconnection of modules defining the main functions of the synchronization device, including the quality control function, is determined by software tva, moreover, to connect the universal control module with a voltage-controlled generator, with data transmission interface modules, with input interface modules, as well as with output interface modules, and perform the connection of synchronization signal consumers and input interface modules using plinths with normally open or normal closed contacts.

The technical result of using the utility model is the ability, after installing synchronization equipment on the network, to perform the functions of one or several types of synchronization devices - a secondary master oscillator (VZG), a network clock synchronization splitter (PC TCC), resynchronization devices (URS), as well as promising and fundamentally new functions without the need for the purchase and installation of additional equipment. In addition, it is possible to measure the parameters of synchronization signals at the input and output of synchronization devices (sources of synchronization signals) without breaking the connection. Measurements of the line parameters in both directions are carried out without disconnecting the conductors from the cut-in contacts in the skirtings. All this leads to lower maintenance costs.

In traditionally used synchronization equipment, the set of functions performed is determined by the equipment bundle, i.e. types and number of hardware modules included in the equipment. Changing or adding functions occurs by installing different modules.

Universal, fully configurable by software, the control module is based on programmable logic integrated circuits (FPGA). FPGA contains a digital implementation of all hardware modules that are part of traditional synchronization equipment and perform the functions of branching synchronization signals, resynchronization, filtering phase wander in the synchronization signal, providing a hold mode and quality control.

FPGAs contain the structure of modules and their relationships. This allows you to download a new configuration via the data transfer interface, which will allow you to change the functions of the equipment without changing the hardware.

In addition to the universal control module, the device has input and output interface modules, data transmission interface modules, protection elements and secondary power sources.

The synchronization device also uses a different, compared with traditional equipment, method of monitoring synchronization signals during operation.

This method provides the ability to measure the parameters of the synchronization signals at the input and output of synchronization devices (sources of synchronization signals) without breaking the connection. To do this, in the device, the field for connecting consumers of synchronization signals and interface input modules are made with

using skirtings with normally open or normally closed contacts.

Usually skirtings are used in cross equipment. For each connected signal, the skirtings contain two types of contact groups electrically interconnected: mortise contacts and open pressure contacts. Mortise contacts are used to connect the cable, and pressure contacts are used to disconnect or switch equipment using breakers.

The plinths allow, by embedding, to connect cables for transmitting synchronization signals and use the clamping contacts of the plinth to connect measuring devices without interrupting communication with consumers of synchronization signals.

In this case, it becomes possible to carry out measurements and tests in both directions, the use of 5-point electrical protection (with the successive inclusion of protection devices in line). There is no need to display control points for measurements, which increases the reliability of the device and the reliability of the measurements.

When using D-sub connectors in the synchronization equipment, in order to measure the parameters of the synchronization signal at the output, it is necessary to disconnect the connecting cable from the required output (remove it from the socket) and connect a measuring device to this output (insert the contact of the connecting cable connected to the measuring cable into the socket device).

When using equipment in synchronization of skirtings with normally open or normally closed contacts, the connecting cable of the measuring device can be connected to any output without interrupting communication with the synchronization object.

An additional effect of using skirtings is a reduction in prices, including due to the fact that it is not necessary to produce special mounting connectors for connecting sources and consumers of synchronization signals.
