User's Manual

DECT Messenger overview 67
The eKERNEL is the core software in the system and must always
be present. eKERNEL is between the incoming and the outgoing
modules and must always be running. The system does not operate if
eKERNEL is absent or non-functional.
Configuration modules
There are two configuration modules:
•
eGRID
The eGRID module is used to make inquiries and to edit the
configuration database. The configuration database (an MS Access
database) stores all the configuration data.
•
eCONFIG
The eCONFIG module is used to set up and configure the system,
messages, and message flows. The eCONFIG is a user-friendly
variant of the eGRID, and can be used either on the DECT Messenger
PC, or on a remote PC.
Incoming and outgoing modules
There are nine modules (incoming and outgoing) that communicate with
the eKERNEL module. Incoming modules receive messages, and outgoing
modules send messages. Table 7 "Incoming and outgoing modules" (page
67) provides an overview of the modules.
