CI-B
Control-In Circuit B: The negative
signal for the CI circuit. With CI-A,
CI-B is an output current driver pair
to the CI circuit. This output pair is
activated when a collision is detected
on the network, either during self-test
(heartbeat) as the SQE test
sequence or after the watchdog timer
has expired to indicate that the
transmitter is disabled.

DO-B
Data-Out Circuit B: The negative
signal for the DO circuit. With DO-A,
DO-B is a differential receiver input
pair from the DO circuit. This input
pair receives 10-Mbps Manchester-
encoded data that is driven by the
DTE (terminal or computer).

DO-S
Data-Out Shield: The shield for the
DO twisted pair in the AUI cable.
