Architecture of the Centre
The Center of Telephone Networks - xPhoNet - consists of three basic parts: a register of networks, a tester of networks and a transit exchange. Logical diagram of xPhoNet is introduced below.
xPhoNet Centre of Telephone Networks is equipped with the following interfaces:
n |
Thin client for anonymous users - web pages accessible for all Internet users (i.e., for professional and non-professional public). A freely accessible part of the xPhoNet website which does not require a name and a password and displays for public majority of information saved in the register of networks. |
n |
Thin client for authorized users - web pages accessible via Internet exclusively for authorized workmen of operators. Normally non-accessible part of the xPhoNet website is concerned. The name and the password are required. This interface allows to operators to display or edit information saved in the register, related to their network. |
n |
Thick client for authorized users - SW for MS Windows NT/2000/XP designated for authorized workmen of operators only. Group of programs implementing functions of supervisory centre and sharing the data continuously being saved in the database of register of networks. |
n |
Telephone ports for testing of networks - VoIP, ISDN30, ISDN2, GSM type interface or standard telephone sets simulating HTS. From the point of view of particular networks, these interfaces seem to be groups of telephones where telephone traffic is simulated among them. |
n |
Telephone ports for interconnection of networks - VoIP/SIP and E1/SS7 interfaces implementing transit of telephone calls of star-type connections. From the point of view of particular networks, connecting bundles allow transit of calls to all other networks connected to any xPhoNet centre. |
n |
Telephone ports for interconnection of centres - VoIP/SIP interface mutually interconnecting various installations of centres of telephone networks. It is intended for international transit of calls or for national transit of calls among xPhoNet centres operating in parallel. |
n |
Data interfaces for operator’s IS - interface for data transmissions between the centre of telephone networks and operator’s control servers. Secured VPN is concerned via which a SOAP secured interface, serving for taking over of data from xPhoNet and delivering data to xPhoNet, is accessible. |
From the xPhoNet point of view, telephone networks are divided into partner ones and others. Partner networks obtain access names and passwords for their authorized workmen, these networks are connected to the tester of networks and to the transit exchange and their IS may be connected to xPhoNet data interface. The operator of the centre of networks initiates a partner network in the register and then workmen of the operator can initiate or update all other data about their network, by means of thin client. Workmen of the operator (or operator’s supervisory centre) also gain the possibility to utilize xPhoNet thick clients. Information about other networks shall be possibly initiated by the centre operator. Information about partner networks is guaranteed by respective operators and information about other networks is without a warranty. xPhoNet is a telecommunication service offered and provided to partner networks.
