M100-ADSL Interface DSL Modem
The LEDs on the Interface Card
LED 1 is illuminated for approx.
five seconds after a reset (self test), and
is then extinguished for approx.
ten seconds (system initialisation). The
modem is ready for operation when
LED 1 flashes continuously in 250-ms
cycles).
LED 2 indicates that there is a connec-
tion between the switch on the mod-
ule and the modem (the LED is illumi-
nated continuously). LED 2 is
temporarily extinguished when LED 5
flickers, i.e. during a data transfer via
Ethernet.
LED 3 is off when the modem is down.
LED 3 flashes on and off in 250-ms
cycles when the modem is in active.
After approx. 2.25 seconds, the modem
goes from the active state to the
“down” state for approx. one second. In
the “showtime” state (= synchronised),
LED 3 is illuminated continuously.
LED 4 is off as long as there is no data
transfer via ADSL. During data transfer
via ADSL, LED 4 flickers at a speed de-
pending on the data transfer rate.
LED 5 is off as long as there is no data
transfer via Ethernet. During data
transfer via Ethernet, LED 5 flickers (in
this case, LED 2 is off).
Pin outs
As an alternative to using the RJ45
sockets to connect the interface card to
the splitter, you can use the pressure
terminals (slot no. 3).
