The TX host application development environment consists of libraries that enable you to configure and control the protocol engines loaded on the TX board. This manual describes the following TDM libraries:
H.100/H.110 switching control library
T1/E1 library
TX SWI library
The TDM libraries provide high-level interfaces for host applications to control H.100/H.110 switching and the T1/E1 trunks. The H.100/H.110 switching control library and the T1/E1 library provide simple synchronous interfaces to the H.100/H.110 and T1/E1 manager tasks. The functions issue requests and wait for responses from the TX board, blocking the calling application before returning control to the application. The TX SWI interface provides an alternative method for controlling both the H.100/H.110 switch fabric and the T1/E1 trunks on TX boards.
The TDM functions use the services of the H.100/H.110, T1/E1, and SWI manager tasks on the TX board through the standard CPI driver and the CPI channels dedicated to H.100/H.110, T1/E1, and SWI control messages.
