How do I configure an ISDN interface in general?
Configuring an ISDN interface on the V!CAS involves telling the V!CAS
a few things about the ISDN service you’re receiving from your carrier
and how to answer calls it receives on this line. After the V!CAS knows
the basic information about this interface, you can begin to configure dif-
ferent ISDN partners the V!CAS can establish connections with.
The settings for our ISDN interface shown above would be configured
in Setup Tool as follows:
WAN Interface:
Here’s where we tell the
V!CAS what type of ISDN service we’re receiving over this line.
Result of autoconfiguration:
In most cases, the V!CAS detects the cor-
rect D-channel protocol at boot time (and during normal operation)
and displays the results here.
ISDN Switch Type
: Normally this is set to allow autodetection. Only
if autodetection is incorrect, unsuccessful, or you need to configure
the switch type manually, set the switch type and channel fields.
For Leased Lines set the appropriate number of channels to use.
For Dialup Lines specify the ISDN protocol used on the D-channel.
WAN Interface:
Here’s where we tell the V!CAS how to answer incoming calls on
this line. This allows you take advantage of the different telephone
numbers provided by your carrier. The V!CAS answers or dis-
patches calls to different services based on the number called
(known as the Called Party’s Number or CPN in ISDN).
