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 7: Example of the site definition table on page 63 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.
Table 7: Example of the site definition table
Site IP address
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 13: Example of logical representation of module links on page 62 and
Figure 14: Example of module links (practical) on page 62, the site and area structure is
shown in Table 8: Site and Area structure on page 63.
