• DMT component channel carrier wave pattern
• Display of the modulated bit number on each DMT component channel in form of diagram and figure.
• Display of user's connection state and testing progress at real time, and present information on local equipment manufacturer and version.

For ADSL network layer, the following items can be tested:

• ISP PING test: Verify the connection of user to ISP provider.
• Simulated PC logon: The instrument can be used to simulate user terminal PC logging on ISP provider to verify if ADSL user can get on the Internet.
• LAN PING test: Verify the PC in connection failure within LAN.
• WAN PING test: Directly PING the website IP to local WAN to verify the connectivity of WAN link.
• The instrument can be used instead of ADSL MODEM to test Internet wire speed and bandwidth available for the user.
• The instrument can carry out simulated ISP logon instead of ADSL modem to check the operating performance of users' terminal equipment.
• PPPOE dialing can determine the users' dynamically distributed IP websites.

For ADSL line, following items can be tested:

• Digital multimeter (DMM): DMM can be used to measure AC/DC voltage, loop resistance, dielectric resistance, capacitance, etc.
• Subscriber telephone connectivity test: The separator in the instrument can be connected to an external telephone to verify the connectivity of subscriber telephone. Estimation of the length of subscriber telephone line
