Emergency stand alone description

The PRLCM with the ESA is a different configuration than the standard
PRLCM. The PRLCM with ESA requires ESA software and special
hardware components. This chapter describes the ESA configuration
separately.
The PRLCM is a remote configuration. Defective or severed
communication links between the PRLCM and the host site can interrupt
service. The ESA feature package allows the PRLCM to provide
stand-alone call-processing ability when loss of communication with the
host occurs. The ESA feature package allows the PRLCM to take over the
call processing functions of the LTC and the central control (CC).
