Back to Top1. What are the options for Internet connectivity in China?
If your office is located within a major Chinese city, you should be able to find Internet offerings very similar to what you could expect in the US or Europe – with one major difference. China Telecom (or its subsidiaries) still maintains a monopoly control of traditional telecom resources. Thus many connections will include both a line rental from China Telecom and a data traffic fee from the ISP.

The following are some of the more common options currently available in China for corporate subscribers. We point out that there may be a few other options such as GSM dial-up which might be implemented in combination with these to create an entire office/remote access solution.

Type
Speed
Notes
Analog dial-up
33-56 kbps
Readilly available but slow
ISDN
64-512 kbps
No static IP address
ISDN virtual leased line
(ITBN only)
128 – 512 kbps
Static IP address
ADSL
512 kbps (normally)
Variable bandwidth, no static IP address, limited stability
Building Ethernet
512 mbps – 2 mbps
Variable bandwidth, available only in some buildings, usually no static IP
Fractional E1/DDN
64kbps-2mbps
High bandwidth, limited availability
Fiber
2mbps-100mbps
Growing availability in major metropolitan areas

ISDN (64 kbps – 128 kbps)
With ISDN, Internet access is provided over the publicly switched telephone network, but in completely digital format instead of traditional analog. ISDN as most commonly implemented within China provides from 64 kbps to 512 kbps to the customer and has a high level of redundancy, guaranteeing a minimum of down time. ISDN can be configured either as “always-up” or for “bandwidth on demand”.

Virtual Leased Line (64 kbps – 512 kbps)
ITBN is the only ISP in China to offer fixed IP addresses for selected ISDN subscribers. This allows companies to leverage the decreased cost of ISDN dial-up with required functionality such as remote access to external subscribers.

DDN/Fractional E1 (64 kbps – 2 mbps)
The traditional approach for corporate Internet access in China has been via DDN (“Digital Data Network”) leased lines, also know as “private circuits”, because they are, in theory, always on-line, allowing use of fixed IP addresses. These are typically delivered to customer premises via normal PST-provided copper telephone wire, but are switched through a municipal DDN network to the ISP. As supplied in China, DDN is used to deliver anywhere from 64 kbps (a “partial E1” connection) up to a full E1 (2.048 mbps). However, due to the low number of subscribers and the need to set up each connection individually, in most cases DDN proves to be the most expensive option in terms of both setup and monthly rental fees.

Fiber (2 mbps – 100 mbps)
Used with increasing frequency by corporate subscribers with high bandwidth requirements, fiber connectivity is now available in for many parts of Beijing and Shanghai – including Beijing’s Sanlitun Embassy District. Fiber is an ideal solution for corporations looking for substantial and scalable bandwidth.

If you are having difficulty deciding which option is right for you then please feel free to contact one of our Corporate Services representative, who will be happy to answer you questions.

Back to Top2. What is the situation with government censorship of the Internet?
The Chinese Internet is very much a regulated entity with all international exits watched carefully by a combination of private and government run filters and software. To the end-user in China, this feature of the Chinese Internet makes itself known with slow download speeds and often arbitrary connectivity to foreign Web sites. Many US news and government sites that may not be accessible over one connection may be easily reached on a second connection. (see ITBN’s technical advantages, below).

Similarly, the concentration of all international traffic into several routes means that many carriers are vulnerable to physical disruptions. In 2001, many Chinese Internet users were stranded when an underwater China Telecom cable near Japan was cut. Some traffic was diverted to alternative routes, but overall the entire national Internet experienced a considerable slow down.

Back to Top3. What are the advantages of using IT Broadband Networks?
ITBN offers subscribers quality and options unprecedented in Chinese Internet Service Providers:

Multiple uplink options
ITBN currently offers three different upload options to residential subscribers. This offers redundancy in light of international network disruption, and also delivers control of the uplink directly to you, the end user. You yourself can choose which of the three uplinks to use as required by your Web browsing habits. All other Chinese ISP’s offer a single default uplink. When you find access to a specific site is blocked, there is nothing that can be done. Only ITBN delivers options.

Bandwidth Allocation
ITBN is the only ISP in China now using sophisticated bandwidth allocation technology to ensure the exact amount of bandwidth delivered to EACH subscriber. With some connectivity packages, ITBN even provides guaranteed bandwidth to the end-user. This technology allows ITBN to maintain constant real time monitoring of network conditions to ensure a smooth and effective delivery of Internet service.

Group packages for remote access solutions
ITBN is the only ISP in China to offer group packages covering both individual and corporate subscribers. Depending on your requirements, ITBN engineers can assist you in configuring your internal network to allow VPN based remote access – with the additional security of allowing access to only your own residential subscribers to ITBN. Add a level of security by using ITBN internal IP addressing – without exposing yourself to the entire Internet.

Back to Top4. What after sales support does ITBN offer?
ITBN offers unrivalled after sales service, with true 24 hour bilingual telephone support. Our highly experienced support staff are on hand to help you whenever you need them. Email based support is also available if you prefer. ITBN is also the only ISP to offer Technical Account Managers to each client.
