Overview
The File based TRAU Record/Playback (Traufunc) module is an optional application that allows Capture/Playback of TRAU traffic.
They are similar to File based HDLC Record/Playback module with additional TRAU broadcasting transmission and multiple receive
features per task. The module also allows to check for command syntax and also transmission / reception of TRAU frames in *.hdl
file format located on server.
Features:
- Checks for the command syntax.
- Receiving TRAU frames in .HDL file format located on the server.
- Transmitting TRAU frames from .HDL file located on the server.
Important Syntax Notation Notes
- Whenever TrauFuncT(E)1:Xxx is used in a command syntax that implies TrauFuncT1: XXX must be used for T1 cards and
TrauFuncE1: XXX must be used for E1 cards.
- All the parameters must be entered in the order defined by the syntax. [parm] means that the parameter is optional and can be
omitted.
- The command is case sensitive for ex: parameters in capital like CONT, EOF must be entered as in capitals.
- Parm1/Parm2/Parm3 - parameter is mandatory, one of the choices Parm1, Parm2 or Parm3 must be specified
- Parameters specified in syntax with all small letters are usually substituted by a specific name or value. While parameters in all
capitals must be entered as they are specified

Examples:
- Displaying syntax of all commands implemented in this dll
Syntax:
run task "TrauFuncT(E)1:help" #*;
- Transmission of TRAU frames from an hdl file located on the server
Syntax:
run task "TrauFuncT(E)1:TxFile" using " 'file_name' CONT/EOF/limit_frame_count 8K/16K SC:BitMask " ts_spec;
where,
file_name: Full path of a HDL server file in single quotes to transmit
CONT: Transmit file in round robin fashion (after the last frame transmit the 1st frame)
EOF: Transmit the file till End Of File (EOF)
limit_frame_count: Transmit the file till the specified frame limit. If file is shorter than specified frame limit and transmission is
continuous (i.e CONT), start transmitting the 1st frame after the last frame till limit_frame_count is reached.
SC:BitMask :sub channel mask. Refer following table.

For Example:
- For T1 Card run task "TrauFuncT1:TxFile" using " file.hdl CONT 8K SC:80 " #1:10;
For E1 Card
run task "TrauFuncE1:TxFile" using " file.hdl CONT 8K SC:80 " #1:10;
This will transmit the file continuously on single stream of 8Kbps on card 1, Time Slot 23and sub channels 1.
- For T1 Card run task "TrauFuncT1:TxFile" using " file.hdl EOF 8K SC:F0 " #1:23;
For E1 Card
run task "TrauFuncE1:TxFile" using " file.hdl EOF 8K SC:F0 " #1:23;
This will broadcast the file till the end frame on 4 streams of 8Kbps on card 1, Time Slot 23 and sub channels 1,2,3,& 4.
- For T1 Card run task "TrauFuncT1:TxFile" using " file.hdl 2000 8K SC:01 " #1:1;
For E1 Card
run task "TrauFuncE1:TxFile" using " file.hdl 2000 8K SC:01 " #1:1;
This will transmit 2000 frames on card 1, Time Slot 1 and sub channels 8.
Note: The transmitting file should consist of a single stream.
- Receiving TRAU frames into an hdl file located on the server
Syntax
run task "TrauFuncT(E)1:RxFile" using " 'file_name' buffer_size CONT/limit_frame_count 8K/16K SC:BitMask UPLINK/DOWNLINK
" ts_spec;
This command will receive TRAU frames and store it in specified path and it is in the HDL file format.
For example:
- For T1 Card: run task "TrauFuncT1:RxFile" using "trau.hdl 10000000 CONT 16K SC:FF UPLINK " #1:23;
For E1 Card:
run task "TrauFuncE1:RxFile" using "trau.hdl 10000000 CONT 16K SC:FF UPLINK " #1:23;
This will receive 4 streams of 16Kbps each on TS 23 cards 1 continuously.
- For T1 Card: run task "TrauFuncT1:RxFile" using "trau.hdl 10000000 2000 16K SC:C0 UPLINK " #1:23;
For E1 Card:
run task "TrauFuncE1:RxFile" using "trau.hdl 10000000 2000 16K SC:C0 UPLINK " #1:23;
This will receive 2000 frames on single stream of 16Kbps, TS 23 cards 1.
