DECT Messenger overview 69
• eWATCHDOG
The eWATCHDOG is a software module that works with the Watchdog
card. The eWATCHDOG sends a code to a V.24 interface (COM
port) on the DECT Messenger PC. This COM port is connected to a
Watchdog card that expects the code within certain time intervals. If
the code is not received within the time interval, the Watchdog card
assumes that the system is down and restarts the PC or activates a
alarm indication.
• eTM
The eTM is the Task Manager, which ensures that the DECT
Messenger modules remain active. If a module fails, the eTM
reboots the module automatically. You can specify which modules
are monitored by the eTM. The eTM can be installed on the DECT
Messenger PC where the eKERNEL is located, and on other PCs if
there are DECT Messenger modules also running on other PCs. The
eTM is always used in conjunction with the eCONFIG module.
Logging module
The eKERNEL has a built-in logging function that provides technical
logging data. For a more user-friendly logging function, the eLOG module
is also available.
•
eLOG
The eLOG module generates log files. These files contain information
about processing individual alarms/messages. The eLOG module is
part of the eKERNEL.
Linking modules
All the modules are software modules (e-modules such as eCAP). The
core module is the eKERNEL. All other modules are input/output modules
or security modules that communicate with the eKERNEL module.
Modules do not communicate with each other, except through eKERNEL.
The communication between a module and the eKERNEL passes through
a TCP/IP socket. (A socket consists of an IP address and a port number.)
The modules can be anywhere in a TCP/IP network. Figure 12 "Example
of logical representation of module links" (page 70) shows logical links
between the modules. Figure 13 "Example of module links (practical)"
(page 70) shows a practical example of module linking.
