IDM Architecture
ISDN-Controller B1 PCI v4.0 – 12 AVM System Architecture 63
z
Messages independent of the operating systems
z A message-passing mechanism tailored to specific op-
erating systems for optimum system integration
z An asynchronous, event-driven mechanism for high
throughput
12.2 IDM Architecture
The ISDN Driver Model (IDM) illustrated below shows how
ISDN is integrated in Microsoft operating systems.
IDM Architecture
The ISDN Driver Model is the framework for all driver compo-
nents of AVM ISDN products. The IDM describes how ISDN
services are integrated and how they are accessed by appli-
cations. It also defines the transparent integration of ISDN
hardware resources in the operating system.
One of the most important features the IDM enables is the
coupling of existing communication components (such as
RAS) with CAPI-based hardware. This connection is realized
by the AVM system drivers such as the AVM CAPI Port Driver
or the NDIS WAN CAPI Driver.
