This paper analyzes different network design options based on IP Multimedia Subsystem (IMS) use for Public Switched Telephone Networks (PSTNs). The analysis shows that operators can significantly reduce their expenditures on network deployment, when using Packet Switching, or transmitting voice and multimedia over IP in PSTNs. Finally, the paper shows economic effects of such design for fixed and mobile network operators.
Keywords: PSTN design, IP Multimedia Subsystem (IMS), techno-economic study.
BANDWIDTH CAPACITY OF TELECOMMUNICATION CHANNEL DURING TRANSMISSION OF LIMITED DURATION SIGNALS
M.A. Bykhovskiy, MTUCI, professor, Dr.Sci. (Tech.); bykhmark@gmail.com
The article presents a formula that generalizes Shannon’s formula for the calculation of telecommunication channel bandwidth capacity for the case when optimal multidimensional ensemble of finite duration is used for message transmission, which allows to ensure a pre-determined probability of erroneous reception. It is shown that as transmission time duration increases, this bandwidth capacity tends to the same one as determined by the famous Shannon formula. The author also compares telecommunication systems which for signal transmission use QAM signals as well as Shannon’s optimal volume-spherical signal ensemble.
Keywords: multidimensional ensemble of signals with finite duration, error probability at reception, speed of message transmission.

THE DEPENDENCE OF THE ELECTROMAGNETIC IMMUNITY OF UNDERGROUND COMMUNICATION CABLES FROM SWITCHING BETWEEN THE CONDUCTIVE PROTECTIVE COVER
A.M. Kalyagin, Ph.D.; a. makarovich@mail.ru
The article provides an analysis of influence of cable armor connection with sheath on underground cables withstanding against external electromagnetic interference. It is shown that the aluminum sheathed cable has higher lightning resistance. But, when you connect cable armor with sheath the cable lightning protection is reduced. The analysis results are proved by experiments carried out at the test site, and long-term observations on existing links. It is shown that underground fiber optic cables are also damaged by lightning strokes.
Keywords:cable lightning protection, isolation of armor from a cover, connection of armor with a cover, communication resistance, storm damages of the fiber optic cables.
