Right:
[code:1]"The primary functions of a transciever are:
Electrical Interface (correctly transmitting and receiving the Ehternet signals on the physical medium)
Transmission
Reception
Idle (not doing anything), and
Collision detection (see your other post on this subject)
In addtion to these the transciever must also provide the following:
Jabber protection (insert a jamming signal onto the Ethernet bus to prevent transmissions while a malfunctioning device is monopolising the bus)
Electrical Isolation (protecting the computer from the bus and vice versa), and
SQE or 'Heartbeat' Test (not used nowadays, provides a means of proving that the collision detection circuitry in the NIC is working by briefly raising the SQE signal during the expected inter-packet gap)"
