Appendix B: Concepts
Configuring data routing on the IPNC
The diagram below shows the basic concept of inbound and outbound data call
configuration on the IPNC.

IPNC Data Call Handling
INDeX Call Handle
Note: The RAS must be configured with the DDI for the incoming call
For Dial in data calls the RAS configuration serves as an intermediate incoming
call handler and allows the first level of PPP call negotiation to be performed.
During the first level of PPP call negotiation the method of authentication i.e. PAP
or CHAP and optional PPP parameters such as BACP, Multi-link Compression
type, or Callback are negotiated.
After the authentication method is determined, the IPNC completes the
authentication process by associating the received PAP or CHAP response
against a Dial in enabled User. By identifying and associating the incoming call to
a particular User the IPNC is then able to check the password held in the User
configuration.
In order for the RAS process to receive the incoming data call the called number
(MSN) must be assigned. This is done in the RAS - Extensions field.
Dial Up or outbound calls are configured using the Service form. Within this
configuration form all aspects of the outbound call are configured. These include
PPP authentication name password and the ISDN capabilities. The Service
configuration form also allows ISDN bandwidth control parameters to be assigned
using the Service-Advance button.
