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 

 

 parameter. See the 

 

 guide 

 

for more information on these features.

 

 

If you are using the OfficeConnect Remote to 

 

connect to a remote site over a leased line link, the 

 

initial setup is very simple.

 

 

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 

 

 

 

 

Power on the unit.

 

The OfficeConnect Remote automatically configures 

 

the WAN port to the appropriate line speed.

 

 

Refer to the 

 

 guide and edit the 

 

WAN port’s configuration as follows:

 

 

From the main menu, enter 

 

.

 

 

Highlight the WAN port.

 

 

Enter 

 

 to display the Edit WAN Port screen
