lit at the same time while the LED of the busy channel is out.
The 'Rec' LED on the right side of the housing (red) displays the operating
mode of the MicroLink dLAN Audio:

LED is lit continuously: Recording from analog (line) input
LED is flashing rapidly: Recording from digital input
LED is flashing slowly: Recording from "Mic" input
The 'Power' LED is lit when the MicroLink dLAN Audio is ready for oper-
ation.
The 'Act' LED is lit when data are being sent or received via the power
supply grid.
The 'Link' LED is lit when a connection to another dLAN adapter has been
established.
When operating the MicroLink dLAN Audio adapter using the web-based
configuration interface, it is also possible to observe the corresponding sta-
tuses of the LEDs (see "The HTML configuration interface for the MicroLink
dLAN Audio adapter" on page 30).
