Exiting OPAC ESA mode

After communications are restored, the CM recovers the OPAC from the
ESA mode. When the OPAC exits ESA mode, the system takes down all
active calls. This action is a cold exit.
When the system restores C-side communication between the OPAC and the
CM, the CM initiates the ESA exit sequence. Before the ESA exit sequence
begins, the CM communicates with the ESA processor over the nailed-up
connection. This communication determines if the OPAC is in ESA mode
and if the system can recover OPAC immediately.
A system exit or a manual exit are two methods for the recovery of the
OPAC.
ESA system exit
A system exit is an automatic exit from ESA mode the CM starts without
operator interference.
The CM starts a system exit if one of the following conditions occur:
