Overview

A console client application used to introduce single, fixed, automatic, and random error such as Logical, MF, BPV, CRC, Framing, and National etc into the incoming bit streams.

The wcs commands supports Bulk delay to apply delay on the entire T1/E1 trunk (full multi-frame) of 1.544 Mbps (T1) pipe or 2.048 Mbps (E1) pipe (applicable to USB Analyzer unit only).

Auto error insertion supports types of error insertions including single logic error, and multiframes. Single Logic Errors as stated above can be inserted at a rate from 102 to 109. In fixed or random insertions, the errors are inserted only in the timeslots that have been selected. Multiframe Errors uses a multiframe mask file that was created by the Tx Multiframe application to insert errors.

Command Set for WCS Error Insertion Includes:

• Error Insertion Initialization:

  Commands to load error insertion dll for the T1/E1 systems

  Example:

  run task "ErrInstnE1:InsertError" #1:1..31 continuous;

run task "ErrInstnE1:InsertError" #1:1..5, 8, 9, 23..30 continuous;
• Error Insertion Settings:

  Commands to set selected timeslots for error insertion

  Example:

  inform task 1 "set txtimeslots 1-5,8,20"; // timeslots 1-5, 8 and 20

inform task 3 "set txtimeslots *"; // all timeslots are selected
  
  

  Tasks to autoinsert errors at fixed and random rate

  Example:

  inform task 3 "set autoinsertmode fixedrate"

inform task 3 "set autoinsertmode randomrate"

inform task 1 "set fixedrate 0.0009348";

inform task 1 "set autoinsertion on"; // starts inserting errors

inform task 1 "set randomrate 0.0034";
  
  

  Display commands to output timeslot information in long and short format.

  inform task 1 "set tscomma on";

Output:Tscomma=on

inform task 1 "display txtimeslots";

Output:txtimeslots=1,2,3,4,5

inform task 1 "set tscomma off";

Output:txtimeslots=1-5
  
  

  Bulk delay commands to apply delay on the entire T1/E1 trunk, supported only in USB or Universal T1/E1 systems. "bkdelaytime" must be set first and "bulkdelayunits" is set in milliseconds or microseconds.

  Example:

  inform task 1 "set bulkdelayunits milliseconds"; // milliseconds or microseconds

inform task 1 "set bulkdelaytime 87"; // set to 87 ms (milliseconds)

inform task 1 "set bulkdelay on";
• Error Insertion Variable Information:

  Commands to output the error insertion variable information such as selected timeslots, fixed rate of insertion, random rate of insertion, autoinsertion mode, fixed, random or undefined, autoinsertion status, on or off, bulk delay units in microseconds or milliseconds, and display bulk delay.

  Example:

  inform task 3 "set txtimeslots 0-31";

inform task 3 "set randomrate .00001";

inform task 3 "set autoinsertmode randomrate";

inform task 3 "set tscomma off";

inform task 3 "display";

Output:TxTimeslots=0-31

FixedRate=0.000000000

RandomRate=0.000010000

AutoInsertMode=Random Rate

AutoInsertion=OFF

TsComma=OFF
• Error Insertion Commands:

  Commands to directly insert error into single timeslot, and commands to set range by "txtimeslots", if timeslot

  Example: inform task 1 "insert logic error into timeslot 7";
