Monitoring ISDN Line Usage
After you have first configured the unit for use with
ISDN, it is important to monitor ISDN line usage to
ensure that the unit is working in the way you expect.
Check the ISDN 1 and ISDN 2 LEDs to ensure that
unexpected calls are not being made or that
connections are not remaining open when you
expect them to have closed.
Even if the ISDN Utilization LEDs are not lit, call with
little or no data transfer may be in progress depending
on how you have connected or configured the unit.
As in a conventional telephone call, charges are made
regardless of what is sent down the line until the call is
dropped.
If you want to ensure that ISDN line usage is limited,
set up ISDN Timebands or set the Maximum Call
Duration parameter. See the Software Reference guide
for more information on these features.
Setting Up a WAN Link
If you are using the OfficeConnect Remote to
connect to a remote site over a leased line link, the
initial setup is very simple.
1 Before you power on the unit, connect an
appropriate WAN cable to the WAN port on the rear
of the unit. If you have already powered on the unit,
switch it off and connect the cable.
For more information about suitable cables, see
Appendix B .
2 Power on the unit.
The OfficeConnect Remote automatically configures
the WAN port to the appropriate line speed.
3 Refer to the Software Reference guide and edit the
WAN port’s configuration as follows:
a From the main menu, enter CO PO .
b Highlight the WAN port.
c Enter ED to display the Edit WAN Port screen
shown in Figure 1-15 .
