The Reader continuously monitors the CGC

health and forces a switchover if health fails.

Automatic

Failed Serial Lane

Controller Link

The Reader forces a switchover when an

enabled serial link from the LPM to the LC

has been interrupted. Usually a downed link

is due to external conditions.
Only the lack of OBU transactions in outgoing

messages to the LC allows a downed link to

be detected. To detect serial cable issues in

the absence of OBU transactions, the

operator must enable Heartbeat messages
