- Platform-independent architecture
- For embedded and PC-based systems
- Powerful CAPI interface
ISDNCode+ is a portable ISDN protocol stack developed and maintained by Stollmann E+V GmbH. It has been ported to many embedded and PC-based systems and supports various ISDN chipsets, CPUs and operating systems.
The stack consists of the D- and B-channel protocol supporting all ISDN functions for Basic Rate (BRI, S0) and Primary Rate (PRI, S2m) lines. All modes (NT, TE) are supported. Hardware driver for all ISDN chips on the market are available. Please refer to the feature list for more details.
The application interface of the stack is an enhanced CAPI 2.0. If required support for legacy interfaces like AT-commands is available.
The operating system interface (OSIF) makes integration into different platforms simple without altering the stack itself.
