Telephony technologies
 Providing of services of telephony on the basis of a data transmission network excludes the necessity of operation of separate networks for data transmission and telecommunication and provides an opportunity of fuller satisfaction of needs of the enterprises in services of telephony.
Company «NVP Ukravtomatika» offers solutions of a corporate telephony which will allow the customer to reduce charges on implementation, support and expansion of the incorporated network and as consequence, to raise profitability of a telecommunication network. One of such solutions is implementation of an IP-telephony.
IP-telephony is the technology providing, alongside with a traditional telephony, a plenty of additional services – voice mail, selector meetings, videoconferences.
IP-telephony is understood as the technology, allowing using the Internet or any other IP-network as means of the organization and conducting international and intercity telephone conversations and transfer of faxes in a mode of real time, and also optimization of conversations inside the organization, irrespective of its size and location. Implementation of IP-telephony is a construction of modern multipurpose system of digital communication on the basis of corporate IP network.
Implementing IP-telephony at the enterprise, you receive a number of advantages:
- Opportunity of construction of a uniform telecommunication infrastructure on the basis of a corporate network;
- Simplicity of construction of the distributed telephone and telecommunication systems due to the distributed architecture;
- Decrease of total cost of system possession;
- Reduction of charges on channels due to an opportunity of an effective use of channels for joint transfer of the data, voice and video traffic;
- Reduction of charges on payment of intercity negotiations;
- Simplification of adjustment, support and administration of a telecommunication infrastructure;
- Opportunity of use of the modern applications using advantages of voice, video and data integration within the limits of a uniform telecommunication infrastructure;
- Orientation to support of the open protocols and application programming interfaces (API), a providing opportunity of integration with a wide spectrum of the modern applications offered now by various manufacturers;
- Opportunity of development of own applications integrated with networks on the basis of distributed architecture;
In the field of introduction of IP-telephony we work only with proved manufacturers of the equipment, such as KIRK Telecom and Hagenuk.
The digital enhanced cordless communication (DECT) is the standard of digital radio access which uses radio frequencies bandwidth very effectively and opens new applications of wireless communication for house, office and private local commercial zones (airports, stations, shopping malls, banks, stock exchanges, exhibition centers, building areas, bid warehouses etc.). It provides the steady high-quality communication protected from not authorized access to users. The standard supports voice and facsimile communication, and also data transmission. Besides it is developed in view of modern telecommunication tendencies, such as convergence of fixed and mobile networks, integration of voice communication and data transmission, multimedia services and simultaneous service from several operators.
In the field of implementation of DECT-telephony the company “NVP Ukravtomatika” is ready to offer proved and effective solutions from such manufacturers of the equipment as Tadiran Telecom, RAD, Oneaccess and KIRK Telecom.
Advantages of choice of DECT
- Quality of the wire communication line - 32k ADPCM
- The highest speed of data transmission among all TDMA-standards
- Opportunity of creation of various systems on the basis of DECT:
- House wireless multi-handset systems that also suit for small office,
- Microcellular wireless corporate systems (office and office automatic telephone exchanges with radio access),
- Microcellular systems of the general using (ÑÒÌ),
- Coexistence of various not coordinated DECT-systems in the general frequency range without necessity of frequency planning
- Compatibility of the equipment of different manufacturers (at presence of GAP)
- Maintenance of transition from cell to cell without break of connection (handover)
- Opportunity of service of one handset in different networks (private and the general using)
- Providing of big traffic - up to 10,000 Erlan/km
- Compatibility with other radiosystems
- Absence of management channel - stability to a radiointerferences
- Low level of radiation - safety for health
