Objective

• Study of various DSL Broadband Technologies.

• Study and analyse various ADSL& other problems in Broadband technology.

• Give solutions and suggestions to remove the Broadband problems.

What is Broadband?

As per TRAI:

Broadband is an “An ‘always-on’ data connection that is able to support interactive services including Internet access and has the capability of the minimum download speed of 256 kilobits per second (kbps) ”

NEED OF BROADBAND

• PROFESSIONAL ACTIVITIES: - Telecommuting, Video Conferencing, Home Based Business, Home Office

• ENTERTAINMENT ACTIVITIES: - Web surfing, Video on Demand, Video Games

• CONSUMER ACTIVITIES: - Telemedicine, Distance learning, Information gathering, Photography, Video conferencing among family and friends

Broadband Access (Classification)

Broadband Access

xDSL (Digital Subscriber Line)

• xDSL– Symmetric DSL• Provide identical data rates upstream & downstream

– Asymmetric DSL• Provide relatively lower rates upstream but higher

rates downstream

• Four main variations of xDSL exist:– ADSL-Asymmetrical Digital Sub’s Line– HDSL-High bit/data rate Digital Sub’s Line– SDSL-- Symmetric Digital Sub’s Line– VDSL-Very-high-data-rate Digital Sub’s Line

ADSL (Asymmetrical Digital Sub’s Line)

Data Rate - Wire Size – Distance

Broadband Components

• Customer Premises Equipment(CPE)• Digital Subscriber Line Access Multiplexer

(DSLAM)• LAN Switches: for aggregating DSLAM• Broadband Remote Access Server (BRAS)• RADIUS and LDAP (SSSC)• Provisioning System

BROADBAND PROBLEMS, ANALYSIS AND SOLUTIONS

1. Why does modem take so long to sync with the CO?

• Reason: - No micro filter installed between phones and the company line.  Poor line quality. Problem with modem in CO.• Solution: - Make sure that the phone line connection to the modem is direct Power up the modem. It should sync with the CO within 5 minutes.

If it still won't sync, call your ISP to report the problem. There could be a problem with your line.

2. DSL disconnects when I answer the phone…

Reason: - Bad internal wiring, or problems with filters, splitter or sockets. It also came when signal is influenced by any high magnetic or electrical signals.

Solution: - You can have told your phone company to do a copper line check and they should be able to determine what is the cause and approximately where it is located

3. ERROR 678: "The remote computer did not respond

Reason: - Wrong connections at broadband CPE. LAN card of PC may be disabled. PC Ethernet card (LAN card) or port fault/ Driver corrupted. Local Line problem between your end and POP of Internet Service Provider.

Solution: -

If ADSL LED is Stable, then take a ping test from your PC to the modem. Procedure for PING Test: start-> run, Then type “ping 192.168.1.1 –t” and

press enter. If reply is ok then check the modem configurations else LAN card problem.

4. ERROR 691: “Access was denied because the user name and/or password was invalid on the domain”

Reason: - Incorrect entered User name or password, or Spelling error. Due to forget of user password. Due to wrong port binding by ISP. Due to authentication problem in AAA server of ISP.

Solution: - Check spelling of User name & password entered. Check Caps Lock Key. Ask BSNL office for password reset.

5. ERROR: 619- “The remote computer did not respond and port was closed”

Reason: - It occurs when another application or process requires the same port as

being used by the broadband / internet modem. Due to corrupted Modem USB driver (If using). Due to Registry Problem in PC. You may have installed a router and is causing you some issues with

connectivity.

Solution: - Most of the time, when you restart your system it automatically resolved. Fix your System registry problem by using registry cleaning software. Uninstall and reinstall your Broadband modem USB driver.

6. Error 718: “Timed out waiting for a valid response from the remote PPP Peer”

Reason: - A problem with the servers at the BSNL (This problem occurs if loading

is high on the system and number of customers exceeds the traffic handling capacity of system or bandwidth is full).

The wrong username and or password were entered when connecting. The modem may need initialization string to stabilize its operation.

Solution: - Reboot the modem or off and on the modem. Make sure that the username and or password entered is correct. If problem still not solve, contact to service provider and make a

complaint to BSNL regarding this.

Results-

This Project report describes the basic idea about the DSL Broadband Technologies, in which the ADSL technology mainly described. The above study is describing mainly about the problems and errors which occur when we use the Broadband or Internet on the PC.

The study will surely help to understand the ADSL broadband technology in present aspects and will surely guide the consumers by making awareness. The service providers also guided by this study and giving Reliable and quality services to the consumers. If the service is very good and complaint solving is very fast, it attracts the consumers which are the main cause of revenue increments.
