AES Input Error Detection
This option can be enabled to monitor the status of the AES/EBU inputs for signal presence and three detailed error types:
Each AES input can be masked for error detection:
The input status may be presented to external monitoring systems using SNMP. The frame controller summarizes such status in-
formation and generates SNMP traps for the frame as an entity or may activate GPOs (if GPIO module(s) are installed). The SNMP
manager may afterwards poll the modules Status (see SNMP documentation for details).
Bus Error Detection
The serial audio data from the frame bus can be monitored for proper positioning of an Error-Flag. A bad Error-Flag indicates a
disturbance upstream (i.e., input signal, input module, other DSP module). The Error Detection can be turned Off and On for
each input from the bus. An LED denotes the status of the busses on the left side.
The bus status may also be presented to external monitoring systems using SNMP.
Lock AES receiver lock status
Validity AES3 validity bit detected
Parity AES parity (data errors detection)
Grey Error detection disabled
