ESA manual exit
A manual exit is an exit from ESA mode that operating company personnel
start at the STAR MAP level through the RTS command. A manual exit is
required if one of the following conditions are present:
•
•
Operating company personnel override a time-out value different from zero to
start a manual exit. Operating company personnel busy the Star Hub units at
the STAR MAP level to override the time-out value. Personnel must use the
FORCE option with the BSY command.
The following steps describe the manual exit sequence:
1. The C-side communications between the DMS-100 CC and the Star Hub
2. The DMS-100 CC determines the Star Hub is in ESA mode.
3. The DMS-100 CC queries the Star Hub for the number of active calls.
4. The DMS-100 CC displays the number of active calls on the MAP display
5. If operating company personnel confirm the ESA exit, the DMS-100 CC
6. If operating company personnel do not want to continue with the ESA
