TW-701D ADSL2+ Tester
Introduction
TW-701D ADSL2+ Tester is a hand-held
communication instrument that supports batteries as power supply,
and has a large color touch 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 Features:
English menu, large color touch screen, and simple operation;
Portable design; built-in lithium battery, and its working time are
over 6 hours;
Multi-task support (test and browsing previous records at one
time);
Save, delete test setup and test results and power-off memories;
Save 7 test setup and 100 test results;
Complete alarm detection and indication;
Communicate with PV via RJ45, and make saving, analyzing and
printing for test results;
Online updating of software;
Webpage browsing.
PC simulation: Simulate PC and dial-up via Modem.
Network layer test: It includes Ping, IP config, Route, Tracert
test.
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;
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 user’s 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 user’s 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 user’s phone.
Estimate the distance of telephone wire.
