DECT Messenger overview 71
In Figure 12 "Example of logical representation of module links" (page
70), four DECT Messenger modules are shown (eCAP, eKERNEL, eIO,
and eDMSAPI). These modules are grouped around the eKERNEL. Each
input/output module (eCAP, eIO, eDMSAPI) communicates with the
eKERNEL through a socket. The default port numbers are shown in Figure
12 "Example of logical representation of module links" (page 70). The IP
addresses are the same if the modules are all on the same PC, but the IP
addresses are different if the modules are on more than one PC. After a
module starts, it contacts the eKERNEL and exchanges data. During this
data exchange, the module indicates the IP address (PC) on which the
module is found.
The illustrations show an example with a site and two areas defined.
These concepts are defined as follows:
•
Site
The site is the place where the eKERNEL resides. A site has a fixed
relationship with only one eKERNEL. If you have more than one site,
you have more than one eKERNEL. Also, you can have only one
eKERNEL for each PC. This results in a fixed relationship among site,
eKernel, and IP address (PC).
Although you can have more than one site in a network with PCs, only
one site can be active at a time. With only one site active at a time,
you can set up a second eKERNEL (that is, a second site) offline. After
the configuration is set, you can shut down the first site, and start the
second one.
Table 8 "Example of the site definition table" (page 71) shows an
example of the site definition table on the DECT Messenger PC, which
shows the link between a site and the IP address of the computer
where the eKERNEL for that site resides.

1 192.168.1.99
2 192.168.1.34
• Area
An area is a subdivision in a site. An area refers to a connection
from an eDMSAPI module to a PBX. For each PBX you must create
an area. The eDMSAPI modules can exist on the PC where the
eKERNEL is running, and also on another PC.
Referring to Figure 12 "Example of logical representation of module
links" (page 70) and Figure 13 "Example of module links (practical)"
(page 70), the site and area structure is shown in Table 9 "Site and
Area structure" (page 72).
