• You must apply to the carrier for the MCID feature before you can trace the A-station in the public network.
• To add a code:

  ADD-WABE:CD=<code for trace>,DAR=TRACE;
  

• Proceed as follows to enable the feature:

  CHA-FEASU:TYPE=A,CM=TRACE&TRACCO; 
  

• To configure a trace code as follows:

  CHA-ZAND:TYPE=ALLDATA,TRCD=<code for trace>;
  

• Timer for tracing jobs (multiple timer, default value 50 seconds)

  CHA-DTIM1:TYPEDH=CO,TRACCO=number; 
  

  Parameters for the trunk (also required for tie trucks):
• Create a class of parameter for lines to be traced as follows:

  ADD-COT:PAR=TRAI; 
  

• Create a class of parameter for lines with initial tracing as follows: (Finland NO2 signaling):

  ADD-COP:PAR=TRAC; 
  

• Define the maximum number of simultaneous tracing jobs per trunk group: The TRACENO parameter must be >0.

  CHA-BUEND:TGRP=<number>,TRACENO=<number>; 
  

  Parameters for stations:
• Assign trace authorization to the station as follows:

  CHA-SCSU:STNO=number,COTRACE=YES;
  

  or

  CHA-SBCSU:STNO=number,TRACE=Yes; 
  

  Parameters for the station or attendant console, for example:

  CHANGE-COSSU:TYPE=COS,COS=<COS of attendant console>, 
  AVCE=MTRACE;
   or
   CHANGE-COSSU:TYPE=COS,COS=<COS of attendant console>, 
  AVCE=MCIDM;
  

  or

  CHANGE-COSSU:TYPE=COS,COS=<COS of attendant console>, 
  AVCE=MCIDA;
  

• For MCID call clearing control (MCID after disconnect):

ADD-COT:PAR=MICC;
