Using the function reference

This section provides an alphabetical reference to the T1/E1 functions. A typical function includes:

Prototype

The prototype is shown followed by a listing of the function arguments. Data types include:

  • U8 (8-bit unsigned)

  • S8 (8-bit signed)

  • U16 (16-bit unsigned)

  • S16 (16-bit signed)

  • U32 (32-bit unsigned)

  • S32 (32-bit signed)

 

If a function argument is a data structure, the complete data structure is defined.

Note: Some parameters are not applicable to both ANSI and ITU-T (CCITT) networks.

Return values

The return value for a function is either T1E1_SUCCESS or an error code.


Note: Call TxT1E1Open before calling any other T1/E1 functions for a board.
