Changing Your Configuration
Auto-disconnect time
If you are using ISDN Dial-on-Demand, your interoffice connection will by
default automatically be disconnected if it is unused for more than 60 seconds,
to save call charges. It will automatically be reconnected when there is new
data to send. You can change the value of the Auto-disconnect timer, or select
Off to keep the ISDN call connected permanently.
I
If necessary, modify the Auto-disconnect timer.
Data over voice
The Data Over Voice (DOV) feature sends data calls over the ISDN network as
though they are voice calls. For those ISDN service providers that have lower
charges for voice calls than for data calls, this feature can give reduced ISDN
call charges. If you are to receive DOV calls, you must have an ISDN directory
number to be used only by DOV calls, entered in the Phone and ISDN
Information page (Figure 7-4). If you are to send or receive DOV calls, the
remote office must also be configured for Data Over Voice calls.
I
Enable or disable Data Over Voice calls.
Caution: Depending on which country you are located in and the ISDN
service you use, using the Data Over Voice feature may not be permitted.
Callback
The AR100 supports callback for outgoing calls. Beyond the small charge for
the initial ISDN call, this allows a remote site to reverse the call charges to a
central office, for central billing of ISDN calls. If you are unsure about whether
this feature is also supported by your remote office, contact your network
administrator at the remote office.
I
Choose whether or not to enable callback.
Update IP networks
If you have both Internet and inter-office connections, your router must be
configured with the correct IP address ranges and masks at the remote office.
I
To check these click the Update IP Networks button at the bottom of the
page. The Remote IP Networks page opens.
Data for destinations within the IP address ranges specified here are sent over
the inter-office connection. Data to all other destinations is sent over the
Internet connection.
I
To add a new subnetwork click the Add IP Network button.
I
To remove a subnetwork click the Remove button beside the subnetwork
you want to remove.
Save changes
I
Click the OK button to save these changes and return to the Update
Configuration page (Figure 7-2).
