General
The ADS-702C ADSL2+ Tester is a hand-held communication instrument
that supports batteries as power supply, and has a large screen
with English display. This product is particularly applicable for
the field cutover, acceptance and maintenance of ADSL equipment,
and can be widely used by ADSL business operators like China
Telecom, China Rail Company, etc, and is the best choice of ADSL
engineers and technicians.

Major Functions
For ADSL physical layer:
Fast
channel and interleave channel.
Line
parameters testing: up and down channel rate, line attenuation,
noise margin, transmitting power, and use rate of channel.
Performance analysis of line error and alarm:
- Automatic
detection and display of such alarms as signal loss, frame loss,
power loss and cell loss etc. at proximal end and remote end.
- 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.
DMT
sub-channel carrier pattern
Display modulated bit numbers on each DMT sub-channel by diagram
and digital
Display user’s connection state and testing progress at real time,
and present information of local equipment manufacturer and
version.
For ADSL network layer:
ISP
PING test
Verify the connection of user to ISP provider.
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.
Instead of ADSL MODEM to test Internet wire speed and flow
available for the user.
Simulated ISP logon instead of ADSL modem to check the operating
performance of users’ terminal equipment.
PPPOE
dialing can know the users’ dynamically distributed IP websites.
For ADSL line:
Digital
multi-meter (DMM) test
Test AC/DC voltage, loop resistance, insulation resistance,
capacitance, etc.
Subscriber telephone connectivity test
Built-in separator connected an external phone to verify the
connectivity of user’s phone.
Estimate the distance of subscriber telephone wire.
