The following steps describe the manual exit sequence:
1. The C-side communications between the DMS CC and the PRLCM are
restored.
2. The DMS CC discovers that the PRLCM is in ESA mode.
3. The DMS CC queries the PRLCM for the number of active calls.
4. The DMS CC displays the number of active calls on the MAP display and
queries the operating company personnel if ESA-exit is desired.
5. If operating company personnel confirms to the DMS CC that ESA-exit is
desired, the DMS CC sends the ESA-exit request to the ESA processor.
6. If operating company personnel does not want to continue with the
ESA-exit, the PRLCM is left ManB. The PRLCM stays in ESA mode.
7. The PRLCM and the ESA processor perform exit operations.
8. The ESA processor tells the LCM to return the LCC card to normal
operations.
9. The ESA processor sends operational measurements, peg counts, and the
reason that the PRLCM dropped into ESA mode to the DMS CC. This
information is displayed in the PM171 and PM181 logs.
10. The DMS CC returns the PRLCM to service.
11. Return the ESA processor and RMM nodes to service.
