Radio and Television Network EOC Technology HFC cost of two
。
This paper, the broadcast industry wide concern the cost of two-way transformation of the initial EOC network analysis, focusing on cost analysis on the transformation of several important factors.
China Cable television After 20 years of development, in China's total length of cable lines are now more than 300 million km, fiber-optic lines to 26 million km, has established a nationwide urban and rural areas HFC Network. In recent years, with the network communication technology, and the triple play of the times the need of competition, local radio and television operators in the active Overall conversion , It is also actively exploring two-way technology, especially Internet access network technology development.
HFC network resources can not be questioned, but after the conversion times for radio and television operators, and many value-added services must rely on two-way network to carry out, in this context, two-way cable networks of radio and television operators face transformed into a key issue.
For radio and television operators, the way of transforming one of the most important technology EOC mainly face two problems: First, technical standards are not unified, the second is the transformation of funding. For many regions, the entire rpm distributed free of charge STB The costs have been overwhelmed, and then implementation of the Reconstruction of two-way network, the funding is clearly beyond its capability. To do this, what is the minimum total cost of ownership TCO for network transformation, rapid return on investment has become the industry issues of common interest.
TCO, includes several factors: cost of equipment, construction, line matching and post-maintenance costs,You are not allowed to view links.

As the saying goes, "cheap no good goods" too cheap equipment will result in construction and later maintenance costs significantly. Therefore, the broadcasting network operators transform, the device is not as small as possible the cost of investment, telecommunications, ADSL is a typical example.
Compared with two-way HFC network, ADSL uses the same two-way coaxial network, after several years of development,You are not allowed to view links. Register or Login, cost estimates have mature experience in value, so the cost of ADSL in the TCO cost model can be modified as a reference EOC.
ADSL-front capital costs: the cost of headend equipment 250 + Line Construction / package cost 150 yuan + Terminal Equipment Costs 200 yuan = 600. It can be seen early in the ADSL equipment into 75%, 25% of the cost of line changes. Speaking for the telecom operators, ADSL which the later maintenance costs include several components, in what percentage of total investment accounted for?
ADSL network construction in the early,You are not allowed to view links. Register or Login, small-scale maintenance of the network, through artificial means, through Tester Form to complete. However, with the continuous expansion of the network, a simple manual testing and maintenance of way can not meet the need.
ADSL network failures common categories are as follows:
?? client failure. According to statistics, in all ADSL Broadband Access failure, the client PC, Modem and other equipment, the highest proportion of failures, of which, there is very largely due to improper user operation.
?? subscriber line faults. ADSL business is carrying on the telephone line, telephone line conditions are so complex that the actual line of maintenance work carried out mainly around two aspects, first opened in the ADSL business before the need for effective evaluation of the line quality test whether they meet the ADSL Business opened requirements; 2 is accurate,You are not allowed to view links.

?? central office equipment failure. Central office equipment including BRAS, DSLAM and other equipment, as the core device users to access Internet, its users access Zhiliang plays a vital role, therefore, must be fast positioning device port failure, so that maintenance personnel short period of time as far as possible, restore the user's business.
