Module eAPI
Introduction
The module eAPI is not a real module, but rather a description of a public
Application Program Interface (API) for third-party developers who want
to communicate with DECT Messenger. This chapter is intended for
developers who want to build an interface to the eKERNEL module.
The objective of this document is to describe how developers can integrate
applications with DECT Messenger. Note that the eAPI interface has
limited capabilities. An alternative to developing your own program is to
contact Nortel and request the development of an integrated solution.
Limitations
Input program functionality only
The functionality implemented in the eAPI interface is limited to the
sending of message requests to the eKERNEL module. This process is
carried out through so-called message request (msgrqs) transactions.
Therefore, third-party application programs that are created using eAPI
technology are limited to input program functionality only.
No central configuration
A second limitation in eAPI is that there currently is no support for
configuration request messages. In all other modules, there is a central
configuration database, where all relevant parameters are centrally
administered. This process is normally carried out through configuration
requests (cfgrqs) from the module to eKERNEL and configuration replies
(cfgrpy) from eKERNEL to the module. As a result, third-party developers
must provide their own configuration techniques (through registry, .INI files,
database, command line parameters, and so on) to control the behavior
of their applications.
Basic architecture
The architecture of eAPI is embedded in the eKERNEL module. The eAPI
interface refers to the ability of eKERNEL to provide a TCP server, which
listens to a specified port, and receives TCP sockets packages that contain
message requests.
