ADSL broadband access service
I Definition
1 Name: ADSL broadband access service
2 Definition: ADSL（Asymmetrical Digital Subscriber Loop）
A broadband technology that delivers high speed data links of up to 8Mbps (downlink) in theory   across existing copper wire telephone lines without affecting voice service.
II Service Features
High speed Internet access, send and receive email, transmit document, retrieve or download information and online games etc.
III Merits
1 High data rate: Theoretically speaking, max. uplink speed can be as high as 640Kbps, downlink rate can be 8Mbps. Users can surf online, read news, play games or download pictures. They can even enjoy VOD by visiting our broadband website.
2 Dedicated bandwidth that is safe and reliable: Compared with shared network, ADSL connects with the equipment room of the broadband network, and users can enjoy dedicated bandwidth. ADSL uses CNC　telephone network that connects to thousands of households．Core network uses optic-fiber that covers the whole country, while all nodes use ATM broadband switch to process information. Information can be transmitted in a fast, reliable and safe manner.
3 Surfing online and making telephone calls at the same time. Through frequency division multiplexing (FDM), ADSL data signal and telephone tone signal are modulated in their own frequency without interference to each other. Unlike dial-up access, you can visit Internet and make phone calls at the same time. Furthermore, as data is not transmitted through telephone switch, ADSL access does not charge you  airtime fee that you will incur when you use dial-up access, it saves you money.
4   Easy installation: add ADSL to existing telephone line, only need to install an ADSL MODEM and a splitter.
IV Service Discretion
i Service Type
ADSL service breaks down into three categories: ADSL service for general public, ADSL service for corporate customers and the last one is for campus customers.
ii Access Rate
Definition: The rate at which a user’s modem is connected with broadband access server, not the effective bandwidth through which the data packet of a user is carried throughout the whole network and reaches the last server. 
ADSL access rates available
a  Access rate uplink
512Kbps
b  Access rate downlink
Different service has different downlink access rate.
a  For general public users: 512Kbps or 1Mbps
b  For corporate users: 1Mbps or 2Mbps
c  For campus users: 512Kbps
  iii Access Model
Currently for general public users and campus users we only offer dynamic IP address analysis, while corporate users they can have either static IP address or dynamic IP address analysis.
Dynamic domain name system （DDNS）：A service that correlate a fixed domain name with dynamic IP address, similar to the use of fixed IP. After the activation of DDNS service, domain name will be bundled with ADSL account through self-service system, then the user can have corporate domain name analysis by  logging onto the Internet via ADSL account number@bbn. For dynamic domain name access, however, roaming is not advisable.
Static IP address: When a user logs onto Internet through ADSL, network authentication system will assign the user a fixed IP address and guarantee that the whole network can visit this IP address. Access through static IP address does not support roaming.
iv Authentication
Access through PPP over Ethernet(PPPOE)
V Network Technical Indicators
i Network Status Quo
At present ADSL network in Beijing from user to IP backbone network has three layers, namely access layer, service aggregation layer and service control layer which provide high performance broadband services.  According to the layout of telecom offices in Beijing and the characteristics of access optic-fiber, PSTN as well as the distribution of users’ telephone lines, we divide urban Beijing into 66 “Zones for Broadband Access Service”. That is to say ， main terminal offices, and their module offices, exchange rooms will form a service zone for broadband access. BRAS of each service zone is in the central office, and every zone has one to three BRAS.
Our current ADSL network architecture in urban Beijing is: through telephone twisted pairwire a user is connected with DSLAM in the equipment room of the terminal office,  DSLAM uses Ethernet interface of  Mbps or Kbps to connect with BRAS through bare fiber，then BRAS will be connected with Beijing IP network through fiber in the form of IP. Suburb areas mainly use ATM uplink but where conditions permit, IP uplink is also available. (Currently for suburb areas only the newly built DSLAM offices in Changping and Shunyi county have IP uplink that is connected to ERX 1400.)
DSLAM FE (high speed Ethernet ports), for uplink port aggregation, 100M connects with 500 users of 512K; DSLAM GE( Giga Ethernet port), for uplink port aggregation, 1000M connects with over 2000 users of 512K. Downlink port for BRAS (FE or GE）≤4K, support VLAN (virtual Local Area Network), uplink port uses two GE to uplink to Beijing IP network.
ii Network Technical Standards
At present all Beijing ADSL broadband networks adopt G.992.1 standard which is as follows:
1.  DMT（Discrete Multi-Tone）coding technique that divide carrier frequency band into many sub-carriers；
2.  Use OFDM or ECM echo cancellation method to allocate different carrier frequency band and sub-carrier for uplink and downlink channel in order to realize asymmetrical uplink and downlink bandwidth.
3.  Define the model of data rate adaptation of subscriber line.
4.  Data encapsulation at link level through ATM cell model
According to the definition of G.992 standard, the max. downlink rate for ADSL using this standard can be  6Mbps，max. uplink rate, 640kbps; but the real data rate depends on the specific line situation and service package a user chooses.
At the same time, ADSL network devices also support following standards:
IETF RFC 2662   1999/08 ADSL Definition of line management objects
IETF RFC 2516   Point-to-Point Protocol (PPP) Over Ethernet
IETF RFC 2865,RFC 2866,RFC 2869  RADIUS and RADIUS
IETF RFC1483    Multiprotocol Encapsulation over ATM Adaptation Layer 5
IETF RFC862     Echo Protocol
IETF RFC1661    Point-to-Point Protocol
IEEE 802.3      Ethernet Network Protocol
iii Customer Access Network
 At present ADSL access model in Beijing is that a customer uses PPPOE software to dial up, then CPE modulates, and DSLAM aggregates to BRAS, thus realize the commencement , termination and management of PPPOE access. Currently through BRAS we use a comprehensive authentication system to authenticate, bill and restrict data rate of our ADSL service. (Please see the figure above)
ADSL station equipment and CPE are connected with each other through telephone copper wire, so fixed phone subscribers can have ADSL broadband access through existing telephone lines. According to test data and real usage, for the widely used twisted-pair copper line whose diameter is 0.4mm, ADSL 512K/1M is guaranteed for access distance within 3 km, and ADSL 2M is guaranteed for access distance within 2.8km.
