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 DATA LED to ensure that unexpected calls are not being 

made or that connections are not remaining open when you expect 

them to have closed. 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 

AccessBuilder ISDN Access Router Software Reference

 guide for more 

information on these features.

Setting Up a WAN Link

If you are using the AccessBuilder 500 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.
