Under
DSP Load
the load of the system is displayed. The usual load is
about 55 to 65%.
• Via the function
PC Logfile
you can record major events of the system.
Every day a new file is created according to the following scheme
yyyy-mm-dd.txt
(z.B. 2004-12-23.txt)
The files are located in the installation directory in the folder
Logfiles
You can read the files with any text editor.
The following events can be activated:
–
Line Events (ISDN/POTS)
: All line events (link connection and discon-
nection) are recorded.
–
Internal Events
: All internal events are recorded in the log file (e.g.
RS232 connecting error).
–
Alarms
: All alarms are recorded.
FIG. 47 EXAMPLE LOG FILE
• Under
System Logfile
you can create a detailed ISDN log file.
–
ISDN Layer 1
: Physical Layer: All messages concerning the physical ac-
tivation/deactivation of the ISDN interface are stored in this layer.
–
ISDN Layer 2
: Data Link Layer: The main task of the data link layer is
to take a raw transmission facility and transform it into a line that ap-
pears free of transmission errors in the network layer.
This layer should
only be activated for the log file if there are potential problems. Please
notice that if this layer is enabled an entry is generated every 8 seconds
and therefore the memory is filled quickly.
–
ISDN Layer 3
: Network Layer: The Network Layer enables that a con-
nection between two subscribers is established by adequate address-
ing. This layer is the most important one for the logging since all con-
nection data is recorded here.
The system saves all messages of the activated
ISDN Layer
. The inter-
nal memory capacity is 128-kByte
1
. The data is filed cyclically.
NOTICE
The log file is created by the PC software. If the PC software does not run, the
logging is not continued.

An entry in the ISDN protocol is about 15 Byte on average.
