    Detection of fatal error frame count at proximal end and remote end;

    Detection of power loss count at proximal end and remote end;

    Detection of signal loss count at proximal end and remote end;

    Detection of interleave channel FEC forward error correcting code count at proximal end and remote end;

    Detection of fast channel FEC forward error correcting code count at proximal end and remote end;

    Detection of interleave channel CRC error frame count at proximal end and remote end;

    Detection of fast channel CRC error frame count at proximal end and remote end;

    Detection of interleave channel HEC error frame count at proximal end and remote end;

    Detection of fast channel HEC error frame count at proximal end and remote end;

    Detection of interleave channel NCD error frame count at proximal end and remote end;

    Detection of fast channel NCD error frame count at proximal end and remote end;

    Detection of interleave channel OCD error frame count at proximal end;

    Detection of fast channel OCD error frame count at proximal end;

    Calculate error second (ES), serious error second (SES), and unavailable second (UAS) of up and down channel;

    Calculate bit error count of up and down channel;

    Calculate total cell, total data cell, total transfer cell.

DMT sub-channel carrier pattern
    Display modulated bit numbers on each DMT sub-channel by diagram and digital mode

Display users connection state and testing progress at real time, and present information of local equipment manufacturer and version.

TRACE function:
    Trace the transmission path of IP pack, display IP routing

For ADSL network layer:

ISP PING test
    Verify the connectivity of user to ISP provider.

Simulated PC logon
    Simulate user terminal PC logging on ISP provider to verify if ADSL user can surf on the Internet.

LAN PING test
    Verify the PC in connection failure within LAN.

WAN PING test:
    Directly PING the website IP or web address to local WAN to verify the connectivity of WAN link.

Instead of ADSL MODEM to test Internet surfing speed and flow available for the user.

Completely instead of ADSL MODEM to simulate PC logon, and verify the operation performance of users terminal equipment.

Obtain dynamic IP address by PPPoE dial-up.

Webpage browsing.

For ADSL line:

Digital multi-meter (DMM) test
    Test AC/DC voltage, loop resistance, insulation resistance, capacitance, etc.

Phone connectivity test
    Built-in separator connected an external phone to verify the connectivity of users phone.

Estimate the distance of telephone wire.
