Telecommunications

The telecommunication sector is certainly one of the strengths of the organization, among other projects including:



SMART SWITCHES SYSTEM

At the present time, the heterogeneity and scalability of information brought to an increase of wired and satellite transmission media. The high safety standards already achieved in the transmission of data allowed us to classify these two as reliable transmissions. This has made  vital the transmission of information, not only protected from intruders, but also reliable from the point of view of continuity. If the recent standard protocol ensures the redundancy to the user, the redundancy of critical points achieves the continuitiy to the backbone.
The Smart Switches System is therefore a physical layer switch that allows the exchange between redundant systems, either automatically or manually (locally or remotely), thus ensuring increased uptime for critical communication circuits. Because the switching is based on Relay, the device will ensure the switching even if the devices (connected to the Smart Switches System) aren’t powered. The device is highly modulated by using different cards that can accept traffic from all the most common physical media, for example optical media and Ethernet.

The exchange system allows the Smart Switches System the intelligent switching which is connected to the intefaces. This switching can verify in different ways:

  • Through the use of a command supervision (local switch)
  • Through a manual switch
  • Through an automatical control logic.
These last features allow  the supervising and the reachability of one or more IP addresses based on the result and the implementation of the switching policies. For example, you can control the exchange of one or more interfaces when the device isn’t reachable through  its IP address and also you can plan what to do in case of return of the accessibility of the IP node.
The context of application of the Smart Switches System requires the activation  of a second device to redound the first-one. This exchange of delivery must take place in instant and automatic way in order to appear transparent to the end user. In the second release of the project, two new types of cards will be introduced: VoIP over satellite and ADSL. These two new cards will use the satellite as a backup network and in some contexts as the main network, but this makes critical the continuity of service and fundamental the hardware redundancy of the equipment used for this type of transmission. Smart Switches System ensures continuity of service through the exchange of intelligent data path in case of failure. This exchange, manually or automatically, will be made in accordance with rules and policies programmable to adapt the system to the particular needs of the network on which will be used.
The device consists of a physical layer switch that allows the exchange between redundant systems, either automatically or manually (locally or remotely), assuring increased uptime of critical communications circuits. Since the relay-based switching, the device provides communications, even when not supplied because the switching is based on relay.  Each card has a common port switch defined "C",  a port "A" and a port "B". In normal condition the port C is connected to port A,  manually or automatically, based on programmable rules.  So that the exchange takes place, port C can switch on port B

Smart Swtiches System can contain until 16 cards exchange A/B put in a 19" standard height of 5 units (5 HE). Multiple devices can work in parallel thus allowing a modular architecture consisting of an indefinite number of trading cards A/B. Remote management is via Telnet, Web or via management program. The intuitive interface allows the following:

 

·        The configuration of the device

·        The graphical display  of the cards switching

·        The Exchange manual (individual or group)

·        The display of any alarms

 

A typical application could be the management of the redundancy of the two routers. These interact via the protocol VRRP (Virtual Router Redundancy Protocol). If the master router has a breakdown the router slave replaces it automatically, so the system notes that the router (A) has a breakdown and it switches the WAN circuits to the router defined B, obtaining  continuity of service.


THE SMART SWITCHES SYSTEM MANAGEMENT

The ultimate goal is to create a software product that could be useful and easy to use for end users who are the beneficiaries of its action plan.

Through this system the user will have full control of the machine, thanks to user friendly screens, both for the configuration and for the supervision. The software allows  to interact with the machine and get the macro-information (state of the basket) to reach the micro-information (state of a single board or power supply).

The software will be used by users who need to

manage the Smart Switches System in order to simplify the configuration, otherwise made by the console.

It is possible to visualize  the current configuration of the device from the program and to modify the configuration according to user needs.

The program will be as an alternative to configuration via console. It will have a macro configuration of one or more racks until you obtain the details of each card. The configuration can be remotely and any c

hange (made trough a graphical interface) will be immediately activated on the device. The main “Actor” of the software system is named Administrator that  would perform the following functions:

  • Configuration change of the apparatus
  • Visualization of the configuration of the apparatus
  • Video display information about the status of the device.

Using the software the “Actor” will have a simple management of the device, for example, he can save the entire configuration into a text file which can be exported to a computer.


RADIO GATEWAY MANAGEMENT SYSTEM

The "Radio Gateway Management System" will have total control of radio communications, and thus of their respective channels, to be managed. This management system shall be installed on user workstations, which will be able to configure the router to connect to Radio Gateway ports 4E & M cards (cards that carry voice and data streams).
At the gates of the cards 4E & M will then be connected to radio transmitters or receivers, so on the basis of the operator can create the interconnection between the doors of Radio Gateway, SGS placed in rooms or at remote sites.



Access to the program is made ​​up of two types of users: the user base and the super user.
The user base User performing connection between the place and the various radio-operator, and display system status Gateway Radio remote sites.
The super user has the same characteristics of the user base, but also has the ability to create new users to the base type and load on the database (through appropriate interfaces) the configuration of each radio Gateway.

In detail, the user (super or base) that uses the management system can perform the following tasks:
• Data entry: the super user can create / edit / delete new user base, inserting / updating data retrieved from the Radio Gateway question, whether it be in the room or at remote sites SGS
• Connection of ports: the user (super or base) can create simple and user friendly interfaces with the interconnection between the devices.
• Displaying the status of remote sites: the user (super or base) displays the status of the equipment located at remote sites. There are three types of status:
OFF: The port is not connected, so it is considered free
RELATED: The port is connected, provides information, site name and port name, which is connected to that port.
FAULT: there is an error on port and provides information, site name and port name, which was connected to that port.
• Reporting: the user can print the information on the status of remote sites, which are described in the preceding paragraph.
