Summary (Cable Test)

 Wire Map Test Result gives the wire map test result for each pair.

When the link is up: The wire map result for each pair is given as seen

by the FTB-700G/800 Series to get a link up. This means that the wire

map result may not correspond to the type of cable tested depending

on the cable(s) used and/or the configuration of the cable mode (MDI,

MDIX, or auto-detection) on both the FTB-700G/800 Series and the far

end equipment. For example, two crossed pair cables end to end used

between the FTB-700G/800 Series and a far end equipment may give a

straight pair (MDI) wire map result.

Note: For 1Gbit/s, both MDI and MDIX can be reported simultaneously since

crossed pairs detection is performed independently for pairs A-B and C-D.

MDI Straight pair.

MDIX Crossed pair.

MDI (-) For 1Gbit/s, straight pair with swapped wires within pair.

MDIX (-) For 1Gbit/s, crossed pair with pair A swapped with pair

B and/or pair C swapped with pair D.

Noise Excessive noise on a pair most likely caused by a link

partner running in 10/100 Mbit/s forced mode. In this

case, no propagation delay or length is reported and

there is no comparison with any threshold.
