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.

Notes |
Analog dial-up |
33-56 kbps
|
Readilly available but slow |

ADSL |
512 kbps (normally) |
Variable bandwidth, no static IP address, limited

Building Ethernet |
512 mbps – 2

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.
