ISDN Software product configurations

Using ISDN Software, you can access ISDN services in three ways:

Configuration type

Description

Channelized

Configure ISDN Software so an application can perform call control and other operations using the NCC API.

This is the interface described in this manual.

ACU

Access ISDN APIs at the ACU SAPI. Using the ISDN Messaging API, an application can perform a wide range of Q.931 ISDN D channel functions.

For more information about this configuration, see the Dialogic® NaturalAccess™ ISDN Messaging API Developer's Manual.

LAPD

Access ISDN APis at the data link layer (Layer 2). Using the ISDN Messaging API, an application can send and receive I-frame data in LAPD messages. This data typically consists of Q.931 messages.

For more information about this configuration, see the Dialogic® NaturalAccess™ ISDN Messaging API Developer's Manual.

Specify the configuration to use when initializing the ISDN protocol stack, as described in Initializing the application.
