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 the event handler by using the LOG command.

Log events

Station line error

The line monitoring feature of the AlphaCom will detect when there is a station line error. Stations are reported down only (not UP). Here line eroor is reported on station 102, board positon 1, line 2:

Board error

Board Down is reported when the AMC-board fail to communicate with a board inside the module. Board error is reported down only (not up). Here the board in position 9 is reported down:

Oct 11 16:15:15 src@Johnson AlphaLog: N001.D065:.Exch:@D65.B09 Board Down

Device error

Device Error is reported if the communication between the AlphaCom and the device fails. A "device" is normally a RIO unit). Here there is an error communicating with device #1:

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

Device OK is reported when the communication becomes OK, and also after restart of the AlphaCom exchange:

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

Device Missing is reported if the device is 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.
