INTRODUCTION

The TPT 10BASE-T Twisted Pair Transceiver lets you use
existing twisted pair wiring as part of an Ethernet network.
Distance and Cable Type
The TPT supports an unshielded twisted pair (UTP)
segment, up to 100 meters (328 feet) of 24 AWG UTP with
an impedance of 85-110 ohms.
Signal Quality Error (SQE) Test
The TPT has a Signal Quality Error (SQE) Test Switch
that lets you turn on or off the SQE (“heartbeat”) test
function. With SQE Test turned on, the transceiver
generates a test signal after each packet transmission that
checks the collision circuit and path between the TPT and
the device attached to the transceiver’s AUI port.
NOTE:
You must disable the SQE test if you attach the
TPT to Version 1 equipment or to a repeater. Version 1
equipment and repeaters interpret the SQE test pulse as a
collision, which significantly slows the network response
time.
Polarity Detection and Correction
The TPT incorporates a Polarity Detection and Correction
feature. This feature lets the TPT pass data to and from the
