Cable Diagnostic
The accuracy for detecting fault free cable length is within +/- 5 meters normally. However, under the following conditions,
the fault free cable length detection accuracy can be beyond 5 meters limit. The frequency of this occurrence is very low.
1. The remote link partner has a termination incompatible with IEEE 802.3 specification (100 £[).
2. A cable coupler is placed within 7 meters from the link partner.
