LAN SOLUTION NETWORK TESTER
If no voltages are present, testing for Ethernet link
pulses begins. If link pulses are found, the advertised
capability, the pairs with link pulses, and the polarity of
link pulses are displayed. The pairs with link pulses are
indicated by reference to the device that would normally
present pulses on those pairs (the hub, switch, or NIC,
assuming straight-through cabling. With a cross-over
cable present, an NIC would be labeled as a hub, etc.)
The AUTO indication is displayed if the device
connected is capable of auto-MDI/MDI-X. If no pulses
are found, but the pattern of termination of the cable is
that of an inactive Ethernet device, it will be displayed as
such.
If the tester does not find any of the conditions
described in this section, it invokes the cable test as
described in
Section 4.2.2 , displaying any single-ended
cable test, full cable test, or “No I/O or Cable” results.
