VOICE
(Yellow) If a Voice port is fitted this LED shows
the status of the voice connection:
■
On – A voice call is in progress.
■
Flashing – Indicates that handset is off the hook
and a dial tone is present or a call is being dialled
or ringing out. It also shows if the handset is
ringing (receiving an incoming call).
WAN
(Yellow) This LED indicator provides
confirmation of the state of the WAN link (if fitted). If
the LED is lit, the WAN connection is valid and can
pass data across the link. If the LED is flashing it
indicates a fault on the WAN port.
ISDN Utilization
(Green/Yellow) These LEDs show
the ISDN utilization as a percentage of network
loading. If you consistently see a continuous ISDN
loading of 100% and you require faster throughput,
then you might consider the following:
■
You could configure the unit to filter some of
the data. See
the
Software Reference
guide
for
more information.
■
An additional ISDN or WAN link is possibly
required to cope with the amount of data you
need to transfer.
