Service Identification

Plug one end of a cable into the RJ-45 jack on either side of NetTool and the other end into any RJ-45 wall jack.

Power up NetTool and select AutoTest. Doing so shows you what service is active on the jack. Based on voltage and other electrical characteristics of the port, NetTool can detect:

Telco: Shows the tip and ring pins.

XCaution

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.

Ethernet: Tells you if the jack is hot, what’s on the other end (hub, switch, etc.), as well as the speed and duplex, level, and polarity. Also shows the segment ID so you can choose the right network (if there are multiple jacks).

Token Ring:

Indicates the presence of a Token Ring network.

No Response: A dangling, flashing power cord Indicates that NetTool senses an Ethernet device but the device is not responding. This usually means the device is powered off.
