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

PPPauthentication name password and the ISDN capabilities. The Service configuration form also allows ISDN bandwidth control parameters to be assigned using the Service-Advance button.
