Modules overview
DECT Messenger consists of separate modules. There are three main groups of modules:
• Core—core components of the software, including security and maintenance tools.
• Input/Output modules—used for sending or receiving messages to or from supported
devices.
• Add-Ons—optional expansion modules adapted for specific customer needs.
• Web Administrator—a web application that enables web-based access to a limited set of
functions.
The following sections provide an overview of the modules. Detailed module descriptions are
provided in Avaya DECT Messenger Installation and Commissioning, NN43120-301.
Core modules
The following core modules are available:
• 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/eGRID
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.
• eGUARDIAN
The eGUARDIAN is a integrated into eKERNEL and is used in conjunction with an input
module that receives data at regular intervals. The eGUARDIAN module checks the data
input at regular intervals. If the input is not received within a specified time period, the
eGUARDIAN module sends a message indicating that an input is down.
• eBACKUP
The eBACKUP module takes care of making a backup of the configuration database at
regular intervals. -
• eTM
The eTM (Task Manager) is a background module that automatically starts up other DECT
Messenger modules in case they are down. Most of the core modules are typically
deployed on the server PC. Exceptions are eCONFIG, which can optionally be deployed
and used from a client PC (with limited configuration capabilities) and eTM, which is
recommended to run on every DECT Messenger PC, client or server.
