Single-Ended AutoTest Results
AutoTest result screens vary depending on the device that
NetTool is connected to.
Note
This results described in this section are provided
as examples of what information NetTool
provides.
Network Drop
If NetTool is connected to a network drop, it displays one
of the following icons to identify the service that is active
on the jack:
•
Telco: shows the tip and ring pins (in the case of
voice being carried on an RJ-45 cable).
Caution
Although NetTool can detect Telco signals, it
is not designed to be used on the public
telephone network. Disconnect immediately.
NetTool cannot reliably discover Telco
information with the AC adapter or serial
cable connected. It also detects ISDN signals
but cannot reliably detect the S/T interface.
•
Token Ring: indicates the presence of a Token
Ring network.
•
Ethernet: tells you if the jack is hot and what is on the
other end (for example, a hub or a switch). It also
provides the speed and duplex setting, level, polarity,
and the segment ID so you can pick the right network
to hook up to a PC (if there are multiple jacks).
•
No Response: A dangling, flashing power cord
indicates that NetTool senses an Ethernet device but
the device is not responding. This usually means that
the device is powered off.
