onsoft ISDN Stack for BRI and PRI |
|
 |
|
|
|
|
|
All the onsoft ISDN protocol stack layers have been developed in-house according to the E-DSS1 standard of the Euro ISDN protocol.
The software covers all the basic functions of modern telephony.
|
|
The ISDN stack is programmed in ANSI C and supports all standard embedded systems
and computer architectures based on 8081, 8051, V25, PowerPC® and Intel® processors.
