Determining Link State
The LXT1000 and its link partner determine the type of link established through one of three
methods:
Auto-negotiation is the only method allowed by the 802.3ab standard for establishing a
1000BASE-T link, although forced operation can be used for test purposes. (See

negotiation is enabled. If not, the LXT1000 forces operation as directed. If auto-negotiation is
enabled, the LXT1000 begins transmitting Fast Link Pulses (FLPs) and receiving FLPs from its
link partner. If FLPs are received by the LXT1000, auto-negotiation proceeds. It also can receive
100BASE-TX MLT3 and 10BASE-T Normal Link Pulses (NLPs). If either MLT3 or NLPs are
received, it aborts FLP transmission and immediately brings up the corresponding half-duplex link.
