User's Manual
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 is a wide range of incoming and outgoing modules available. They all communicate with
the eKERNEL module. Each module has a specific incoming or outgoing function. This means
that the incoming modules can receive messages and outgoing modules can send
messages.
Table 6: Incoming and outgoing modules on page 59 provides an overview of the modules.
