Telecommunication In the Bed of Development

Introduction

Ministry of post , telegraph and telephone and its subsidary companies started the year 1382 whil the generalities of bill for changing the name of P.T.T to ministry of communication and technology of information was approved .

This change in name , brings hope to whole society , particalary to communication and information society and it is expected to be a factor to change pointview of the outhorities in the country .

The second important event in beginning of the year 1382  was the identification of the winner for prepaid mobile phone tender .

In this tender which is a new experience in communication sector ,one iranian cooperative along with four European and international companies were announced as winners of tender for carring out the work .

In telecommunication year of 1381 , Iran had more acceleration in comparison of previous year in technology development .

Development of optical fiber , cabling of 19000 kilometers of optical fiber all over the country , the efforts of high council for information in TCI and private sector and approval of Takfa plan and preparation of pilot document for development of information technology , establishment of committee to study computer and internet crimes were some of the considerable measures of telecommunication of the country in the last year . But with regard to increasing development of communication and people need more information and cultural problems for development of information technology that , is one of the most important challenge in development of such a valuable phenomenon , pushes  telecommunication personnel to increase their knowledge and getting ready to face electronic world .

Today while we are looking forward ro telecommunication`s day in 2003, telecommunication society in the country is aware of passing this inavoidable youte.

However , telecommunication sector of Islamic republic of Iran with all technical capabilities could be able to reach foundamental changes and recordless achievement .

This article introduces qualitative and quantitative achievements in last year . Telecommunication in Iran with such a policy , welcome the year 1382 . this year with regard to Noroz message of revolution leader , was named the year of serving people and telecommunication in this year as one of the large organization in the country could play main role in this regard and like last year presents successful face .  

Optical fiber

TCI in the way of development in optical fiber network as infrastructure of transmission network in the country , takes effective steps , as function of this company in optical fiber network was 2759 kilometers in the end of 1380 and cabeling of intercity optical fiber until the end of 1380 was 8842 kilometers that includes 3450 kilometers TAE project and 5392 kilometers PC and SC loop .

It is necessary to say that the main sections of developed optical fiber network in the country were carried out as framework of first to third  development plans , in the manner that until the end of 1381 , establishment of this huge network in the history of telecommunication development of the country was recordless and with regard to implementative operation of this project , engineering , installation and commissioning of abut 19000 kilometers of optical cable was carried out in remote areas and this is one of the longest network in the country . this network connected all centers of provinces and main cities and is main communicative artery and infrastructure of the country .

The important point is that , in 1381 more than 8500 kilometers of optical fiber in the communication  network of the country has been used .below table presented function of optical fiber in the country in the first , second and third plans until the end of 1381.

 Function of optical fiber During first , second and third

Five- year plan (until March 1993) in the country

See table

-It should be said that condition of optical fiber cabling for main lines in the country was 9969 km until 1380 and function of the year 1381 up to 24.12.81 was 8500km .  

Data communication

The first phase of third plan for development of data network which include creation of a powerful in frastructure for communication network started from 1379 . In this phase, 420 telecommunication center in 185 larg cities were completely covered by national data network and enables  delivery of high speed data and internet services to commercial and professional subscribers and ISPS . National data network can provide distribution of international  high capacity internet in all over the country for ISPS and leading subscribers . In addition , making direct  connection of internal internet sites through inside routes of country (withat transmission of internal traffic to outside) is part of capabilities of the network . other main dury of this network is to make VPN for organizations , institutions and large companies (enterprise) . Also, It could be mentioned , intallation and commissioning of routers (edge) of  network in 34 points of 28 province centers , 760 ports of IP with high speed for ISPS and leading internet subscribers and delivery of internet to 118 ISPS in 1380 . International internet communications had considerable growth in the same year from 44MBS to 87MBS that all of that is related to first phase of the plan . phase two would have higher jump at data communication and estimated to have 400 percent growth . Implementative operation of phase two started from 1381 in the manner that until the end of the year , capacity of information transmission reaches 10578 megabite and 162 cities are provided by information transmission network and at present time the number of active ISP is more than 950 center . It is necessary to say that in the year 1381 , capacity of information transmission network is increased to 5880 megabite.

Back bone Network 

This network is supplier of inside and international communication and now works in the frame of 8 SC centers (couple) and 84 PC centers . with regard to expansion of new services, particularly broud band in the world , TCI has studied to move the network toward powerful network , so that It could be cable to handle huge telephone and data traffic . In this way , with regard to complete coverage of the country by optical fiber , the future of the network could be developed by considering NGN(Next Generation Network) . In this way , differnt proposals of companies were reviewed and It could be possible to tender the procurement of the project.

Restructure in Telecommunication

 However development of telecommunication sofar was , by means of government help , but , private sector sould be recalled for multilaterial development and potential capital of other sectors sould be used . In this regard authorities of TCI have decided to restructure and privatize telecommunication that its legal procedures have prepared in the articl 124 of third development plan .

On the basis of this , TCI will be changed to professional mother company and other 31 companies becames affiliated to mother company . This company comprises of 28 province companies of mobile phone and 3 new companies ( Data , mobile communication , Backbone “engineering and technical” and shahid gandi cables companies ) .

Besides TCI , organizing institution for giving licences and supervision at post and telecommunication section would be established and the duty of policy making in all sectors is at responsibility of  P.T.T with structure and task approved by ministry of communication and information technology . In this condition , ministry at the top of pyramid , organization for assignment of regulations at second grade , TCI at next grade and implementative companies of post and telecommunication and private sector are at the base of pyramid .

Privatization in TCI

TCI in order to perform the A and B parageraphes of article 124 law for third development plan of the country has recalled for cooperation whit the aim of freedom , privatization , attracting private sector participation at development of fixed phone network and restructing of telecommunication that results in development of  telecommunication and increasing employment .

To achieve that , five methods of participation of private sector have used as fllow :

1.                             At present situation , part of telecommunication works , with keeping ownership of telecommunication , for operation and maintenance as cubic contracts , are given to private sector , suchas , maintenance of network , civil , intercity lines , …..

2.                             with preserving ownership of telecommunication , all affairs of maintenace and operation of telecommunication centers are given to private sector . in this method , private sector will receive part of the incomes as contractor shares .

3.                             In the area of the non-mather telecommunication networks (from subscriber to the first PC intercity center) for development and establishment of telecommunication centers form of the described projects , through tendering , non-government sector is invited to participate .

4.                             Non-government sector is invited in not only financing , but also telecommunication projects , maintenance and operation of established centers and amount of contractor share for maintenace and operation and instalments of spended capital is determined as pretender mechanism .

5.                             Establishment of telecommunication centers with capital and ownership of the private sector .

At present time in the fixed telephone section , about 2000000 fixed telephone are given and 2000000 credit mobile phone is assigned to private sector .

Fixed Telephone

In the fixed telephone section which is the most importand and spread activities of TCI , statistics shows that the number of operating phones from 5824968 lines at the end of 1375 reached to 12934416 lines at the end of 1381 , this shows growth of 122 percent . In the other words , the number of operating fixed telephone during the six year become twice as much .Also the function of operating fixed telephone in the year 1381 is 2037844 lines that is 35 perecent of the whole six-year function .

Teledensity

Teledensity of the fixed telephone from 9.7 lines for ever 100 people at the end of 1375 reached to 19.73 lines at the end of 1381 that shows growth of 103 percent . the function of 10.03 percent of this index in six-year study caused the teledensity to more than twice as much of the beginning of the period . Also the function of the teledensity in 1381 is 2.86 percent that is 29 percent of the whole period .

Rural communication

TCI along with development of the telecommunication network in the cities , tried to help rural dwellers to take advantag of telecommunication connections which could have valuable role in social-economic relations . in the manner that the number of the villages having connection from 14535 villages at the end of 1375 reached to 28062 villages in 1376 and now more than 36000 villages in the country have telecommunication . It is to say the function of connecting to villages during the six years (79-81) is equal to 21485 villages that shows 148 perecent growth .

The function of connecting villages in 1381 is 4127 villages that is 20 perecent of the six-year of the whole function .

Transfer of this service in provinces that have necessary equipment and signal (ss.7), has already started .

At the present , Telecommunication network of the country is equipped by 20000 ports 2B+D and 350 ports 30B+D that are gradually transferred.

2-code od debit card

This service is used in order to help subscribers who have not independent telephone line , perticulary at high density places like , garrisons, universities , dormitory and tourism industry and users with their own cost can make intercity and international connection by using one telephone line . This service from the year 1380 in different provinces by private sector is commissioned and operated. 

With considerable welcome from this service , now the code of debit card is active in 25 provinces and in future phase will change to city and national networks .

3-showing number(caller ID)

This service shows the number of caller on the telephone screen of called .

With good welcome of this service , now , 50 percent of Telecommunication network is equipped by this service that in case of completion of signaling network (ss.7) , this figure will reach to 100 percent . This service reduced considerably the number of phone troublesome at the networks which are equipped by this service
