AlphaCom system log

The AlphaCom system log provides technical events for monitoring the health of the AlphaCom system. The system log includes the following type of events:

AlphaPro log configuration

• Station Line error
• Board down
• Device/card cage error
• AGA line error
• Software error
• Remote input on/off
• Customized event logging

In AlphaPro (Exchange & System > System > Logs and Errors) it is possible to configure what events to include in the system log. By default all events are included.

It is also possible to configure customized events in the system log. This is done in AlphaPro by using Event programming.

Log events

Station line error

Oct 11 14:06:21 src@Johnson AlphaLog: N001.D065:.Exch:@D65.B01-2 Line Down: CD Open St 2 "102 -"

Board error

Boards are reported down only (not up). Here the board in position 9 is reported down:

Device error

Error on communication with Device #1 (Device is normally a RIO unit):

Oct 10 17:51:36 src@Johnson AlphaLog: N001.D065:.Exch:@D01        Device Error

Reported after restart if device is defined and OK

Oct 10 17:51:37 src@Johnson AlphaLog: N001.D065:.Exch:@D01        Device OK

Device not responding after AlphaCom startup:

Oct 11 16:16:54 src@Johnson AlphaLog: N001.D065:.Exch:@D02        Device Missing

Card Cage

Reported OK when all boards in the module are up and running (the module is operational)

Oct 10 12:54:45 src@Johnson AlphaLog: N001.D065:.Exch:@D65        Card Cage OK

AGA error

An AGA error is reported if the audio link between two nodes in AlphaNet becomes faulty. Here the first line on board position 23 (B23-1) is reported faulty. The audio links are supervised by a test tones issued at regular intervals. Signal Level (SL) is the level measured when there is supposed to be a tone, Noise Level (NL) is the measured level when there is no tone (silence). Signal level is normally in the range 80 - 90. If the signal level is below 40, the AGA error is reported.

Oct 13 14:23:28 src@AlphaComE AlphaLog: N001.D065:.Exch:@D65.B23-1  AlphaNet Line Down:SL=  8 NL=  8

When the audio link becomes OK, the line is reported UP. Signal level 86 in this example:

Oct 13 14:23:59 src@AlphaComE AlphaLog: N001.D065:.Exch:@D65.B23-1  AlphaNet Line Up:SL=86 NL=  8

Remote Control Input RCI

RCI's are reported....

Oct 13 14:22:41 src@Johnson AlphaLog: N001.D065:.Exch:ALARM 1 ON.
Oct 13 14:22:39 src@Johnson AlphaLog: N001.D065:.Exch:ALARM 1 OFF.
