Hardware Description
1.5.7.1 LED Status Indicators (LED1 to LED9, and ILFI)
LED1 (HK1)
is low when analogue port 1 is off-hook, high when on-hook.
LED2 (HK2)
is low when analogue port 2 is off-hook, high when on-hook.
LED4 (CN2)
is high when analogue port 2 is connected to the ISDN network, low when not connected.
LED8 (AR)
is pulsed high and low until the ISDN line is activated, when it remains low constantly.
LED9 (CN1)
is high when analogue port 1 is connected to the ISDN network, low when not connected.
ILFI
is high when an ISDN Link Failure is Indicated, low when the link is operational.
The functions of the LED and ILFI indicators are set out in the table below:
