Subject of this application note is an ISDN/LAN Router, a communication system that
enables two LANs to communicate via the ISDN.

ISDN/LAN Router
The structure of the whole system is shown in Figure 85. The router itself is realized as
a stand alone solution. It is connected to a standard PC for software download and
maintenance control only. After the download the system works fully independent of the
host PC.
The hardware of the ISDN/LAN router consists of an application specific part and a
processor system. The application specific hardware is mainly based on the SIEMENS
Component MUNICH32 (Multi Channel Network Interface Controller for HDLC) and a
standard LAN controller. Both devices are integrated in the same processor system.
The software of the ISDN/LAN router is formed by integrating the MUNICH32 Device
Driver Module (DDM) and the corresponding LAN controller Device Driver Module in a
Device Driver System (DDS). The device driver modules build a platform to implement
the routing strategy in a separate application module.
The application specific hardware, the MUNICH32 Device Driver Module and the
application module are the main aspects described in the following chapters. The
structure of the processor system is briefly illustrated. The DDS service routines are
explained as far as necessary to understand this special application. It is suggested that
the reader has some knowledge about the MUNICH32 before reading this application
note. Detailed information about the MUNICH32, its features and memory structures are
given in the MUNICH32 PEB20320 Data Sheet.
