On December 20, 2000，the former China TieTong----China Railway Communication Co., Ltd. (China Railcom), was founded. At January 20, 2004, it was shifted from the Ministry of Railways to the administration of the State-owned Assets Supervision and Administration Commission (SASAC) and its name was changed to "China TieTong Telecommunications Corporation." Ever since its incorporation, China TieTong is a major state-owned basic telecommunications operator.
With total assets of 42.4 billion RMB and a staff of 72,000, China TieTong has established 31 provincial braches (including those located in the autonomous regions, municipalities directly under the Central Government), 316 municipal branches and five holding subsidiaries. With its networks characterized by nationwide coverage, advanced technology and complete functions, China TieTong demonstrates its strength in quick response and flexible networking due to its completely uniform dispatching and management over all its networks. In addition to varied value-added services, currently it also offers basic telecom services to the public, including: domestic/international voice, data, image and multimedia communications, and domestic communications resource leasing service.
With perseverance in excellent services to win market shares, high quality to build the brand, and differentiation to enhance competitiveness, China TieTong has never given up its endeavor to deepen reform and to reinforce management. As a result, over the three years since its foundation, China TieTong has kept a track of record-making performance--annual revenues from main businesses increased by more than 37%, fixed-line subscribers doubled every year, and the number of Internet broadband users in 2003 was 8.52 times of that in 2002.
Through its long history of providing communications services to railway transportation, China TieTong has trained its people and enriched its experience, and obtained the strength to provide high quality services particularly to cross-regional and cross-industrial clients. On the basis of honesty and integrity, we are willing to cooperate with friends from all circles for joint development in the future.

Looking into the future, China TieTong will as always insist on the philosophy of "Doing pioneering work with devotion, being innovative by keeping learning, improving efficiency by cooperation and competition and building the brand with integrity", and take the advantage of being one of the pilot exclusively state-owned enterprises where a board of directors will be set up as . By means of establishing a modern enterprise system, we'll comprehensively organize and implement the development strategy, deepen the reform at the corporation level, set up and gradually perfect a new system and mechanism suitable for constant market changes, and endeavor to grow into a competent basic carrier in three to five years.

Network Profile
From 2001 to 2003, China TieTong has made great efforts to integrate, upgrade and rebuilt its original networks by adopting the most leading-edge technologies, and has basically completed the construction of trunk transmission network, switching network, data network, MANs and the infrastructure for railway communications and interconnection. Therefore, China TieTong has reinforced its capability to provide telecommunications services to the public, and materialized the transform from a dedicated railway communications provider to a public provider.

Currently with its varied services covering nearly 300 LANs nationwide, China TieTong has 150,000 kilometers of communications lines (including 100,000 kilometers of fiber cables), nearly 30,000 ports for various data services and 3600 kilometers of digital microwaves. In addition, its total switch capacity exceeds 18 million lines.

I. Backbone Transmission Network
When China TieTong was just founded, its backbone transmission network was not completely digitalized, whose bandwidth only reached 622 Mbit/s. After two years' continuous construction and upgrade, China TieTong has built a high-speed backbone optical transmission network composed of five fiber loops: Northeast, Northwest, Southwest, Southeast and Beijing-Shanghai-Guangzhou Loop. Incorporating DWDM and with a capacity of 400 G, this network covers most of the cities in the 31 provinces in China, and a distance of 52,00 kilometers.
Beijing-Shanghai-Guangzhou Loop: With a total length of 8080 kilometers of optical cables, this loop covers three municipalities directly under the Central Government and eleven provinces, and involves 25 core nodes and 101 stations. The DWDM 40í10Gb/s system is opened between the three nodes of Beijing, Guangzhou and Shanghai.
Southwest Loop: With a total length of 5500 kilometers of optical cables, this loop covers the municipality of Chongqing, and eight provinces, and involves 15 core nodes and 85 stations. The DWDM 32í 2.5Gb/s system is established with self-owned fiber cables.
Northwest Loop: With a total length of 11000 kilometers of optical cables, this loop covers the municipality of Beijing, six provinces and three autonomous regions, and involves 22 core nodes and 113 stations. The DWDM 32í 2.5Gb/s system is set up with self-owned fiber cables.
Southeast Loop: With a total length of 5860 kilometers of optical cables, this loop covers the municipality of Shanghai, and four provinces, and involves 15 core nodes and 55stations. The DWDM 16í 2.5Gb/s system is set up with both self-owned and leased fiber cables.
Northeast Loop: With a total length of 5668 kilometers of optical cables, this loop covers the municipalities of Beijing and Tianjin, and three provinces, and involves 18 core nodes and 108 stations. The DWDM 16í 2.5Gb/s system is established with self-owned fiber cables.
Up to now, mainly incorporating fiber cables with satellites and microwaves as supplements, China TieTong has established a nationwide transmission network characterized by high capacity and high speed.

II. Telephone Switching Network
At the beginning of the establishment, China TieTong's Telephone Switching Network was dedicated to railway transmission, involving 56 Railway Administrations as its numbering units with a capacity of only 2.28 million lines. After two years' construction and upgrade, currently this network is beginning to take shape. With a switch capacity of over 18 million lines, it covers 282 of all the 343 numbered regions nationwide, and has been interconnected with networks of all the other telecom carriers.
In addition, great achievements have also been obtained in the following aspects:
We have established a backbone intelligent network at the nationwide level and intelligent networks as well at the provincial level, which are capable of offering varied voice and value-added services;
We have commercialized a "Two-way Intelligent Conference System" and an IP videoconference system;
We have reaped first fruits in establishing a national billing and settlement center and 29 provincial billing centers, which enables China TieTong to be the first carrier offering detailed records for local calls:
We have set up a national customer service system and opened our national uniform access number 10050.
We have established supporting networks, including S7 Network, Digital Synchronized Network, Billing Network, and so on.

III. CRNET
Covering nearly 300 LANs, CRNET is a high-speed broadband IP network featuring nationwide coverage, uniform management and centralized dispatching. It provides a wide range of services including voice, image, fax, data and MPLS VPN with a core switch capacity of 320G and a backbone trunk bandwidth of 10G.
IV. Broadband Data Backbone
The ATM-based broadband multi-service integrated data network provides a backbone bandwidth of 2.5 G and an access bandwidth of 622 M/155M, covering over 300 LANs with its 138 nodes.
