Enable Bus Driver
Selecting this option turns on all module bus drivers (from tri-state mode).
From C8000 Bus Output Mux
The multiplex mode for incoming audio signals from the audio bus can be set to 2ch or 8ch.
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/EBU 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 Functions Setup” on page 62).
Bus Error Detection
Monitors the serial audio data from the frame bus to properly position an Error-Flag. A bad Error-Flag indicates a disturbance up-
stream (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.
Lock AES receiver lock status
Validity AES3 validity bit detected
Parity AES parity (data errors detection)
Grey Error detection disabled
Green No error detected/PCM audio
Yellow No error detected/non-audio (Dolby E, D)
Red Indicates an error condition
Grey Error detection disabled
Green No error detected/PCM audio
Yellow No error detected/non-audio (Dolby E, D)
Red Indicates an error condition
