Modules overview

DECT Messenger consists of separate modules. There are three main

groups of modules:

• Core software modules

• Input and output modules

• Security modules

The following sections provide an overview of the modules. Detailed

module descriptions are provided in DECT Messenger Installation and

Commissioning (NN43120-301).

Kernel modules

There are two main modules that are used for the core software:

• eKERNEL

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 nonfunctional.

• 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.

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. Each module has a specific incoming function,

outgoing function, or both. “Incoming and outgoing modules” (page

16) provides an overview of the modules.
