WAN Protocol Device Drivers

The NComm Device Driver and its associated API provides the interface between TMS or other WAN Protocol Software and the Dallas framer device driver. Hardware implementations of complex systems may involve various & mixed devices that access different WAN technologies. To accommodate this potential, all NComm Device Drivers are archetected to:

• Work co-operatively (T1 with T3, etc.)
• In the case of SONET/SDH a Polymorphic Device Driver Mapping Methodology is followed that permits many device drivers to appear as one virtual device to the SONET/SDH Software; this methodology maintains a commonality in general device driver development
• All Driver APIs are comprised of a set of ANSI C functions and macros that handle the interaction with the framer device
• All drivers are OS independent and may be directly used with such popular RTOS like Linux
