See SQE.

Also known as SQE (Signal Quality Error), a test between the transceiver/MAU and the DTE to ensure that the collision detection circuit in the transceiver/MAU is working. The heartbeat function must be disabled when a transceiver/MAU is attached to a repeater. Every time a transceiver/MAU has successfully completed a transmission, it must send the SQE to the DTE to which it is connected to confirm that the collision detect circuit is functioning properly. This continual "pulsing" is referred to as heartbeat.

In an IEEE 802.3 network a circuit (normally part of the transceiver) which generates a collision signal at the end of a transmission. This signal is used by the controller interface for self testing purposes.

Telstra Cable uses an authentication system nicknamed "the heartbeat" which is similar in concept to a "ping. Every five minutes or so, a message is sent to your computer to see if you're still there. Several applications like firewalls, Win98/ME ICS and VPNs block this message, causing the connection to drop out regularly. While there are plans to ditch it, it was originally used provide people with multiple, independent connections using the one modem between several computers and maintain independent usage statistics for each one.
