LINK SIGNAL TYPE

Three different signals can be used to establish a Link: a Link Code Word, an NLP or an MLT-3 waveform.

The Link Code Word is specific in both Link speed and duplex mode. The NLP is specific in speed (10Mbps) but ambiguous in duplex mode (half or full). The MLT-3 waveform is also specific in speed (100Mbps) but ambiguous in duplex mode. Duplex modes for equipment that use NLP or MLT-3 signaling must be

known to ensure proper Link operation.

(Example: a switch port can be configured to a 100Mbps full duplex mode of operation. Most switches use MLT-3 signaling for this mode. When this port is connected to a NIC in a full Auto-negotiating mode, the NIC will assume the switch port is in a half duplex mode based on the MLT-3 signal. The duplex configuration mismatch will cause the Link to perform poorly due to high error rates and collisions.)

The LanMaster 25 indicates an NLP signal by alternately blinking the 10TX and 10FD indicators. An MLT-3 signal is indicated by alternately blinking the 100TX and 100FD indicators. When this condition exists, both Link Partners must be configured for the same speed and full duplex mode or one must be configured for half duplex operation and the other in full Auto-negotiation mode for the Link to operate properly.

BATTERY LIFE

The LanMaster 25 remains on until the “Test” button is pressed and released a second time. Check that the unit is off (all indicators are dark) after each test to conserve battery life.

APPLICATIONS

Network Planning - Identify capabilities of installed equipment for LAN upgrades without opening the case. Installation - Verify physical layer connectivity to the far end. Link activation signals verify two way continuity and identify connected hub/switch port.

Trouble Calls - Reduce troubleshooting time by ensuring the Link is active and no faults are detected. Locate physical layer problems with built-in tone generator and standard tone probe.

Moves, Adds and Changes - Identify correct wire pair with tone generator feature and verify Link is operating after punching down new connections.

Network Management - Test current configuration of installed equipment to determine if modes have been configured manually and type of Link signaling used.
