Decoding generates one or more lines in the format:

GSMAb MPTYPE TYPE
ctrl-field

With the following representations:

• MPTYPE: Management Procedure type:
  
  
  • RLM: Radio Link Management.
    
  • DCM: Dedicated Channel Management.
    
  • CCM: Common Channel Management.
    
  • TRX: TRX Management.
    
  • O&M: Operation and Maintenance Management.
    
    
• TYPE: message type.

The control fields are comprised of IE's; each IE is decoded according to two formats:

• Identified format:

  IE:(xx) len:y >> designation
  value

With the following representations:

• xx: Value in hexadecimal of the IE code.
  
• len:y Length of IE content (after 2 IE header octets).
  
• designation: IE standardized designation.
  
• value: IE contents in hexadecimal.

• Detailed format:

  IE:(xx) len:y >> designation
  octet 3 : b7-b0 designation
  octet 4 : b7-b0 designation
  ...

With the following representations:

• xx: Hexadecimal value of the IE code.
  
• len:y: Length of IE content (after 2 IE header octets).
  
• designation: Standardized IE designation.
  
• octet i: Row of bits in the IE.
  
• b7-b0: High-order bits for the sub-field with designation.

When IE's do not have decoding corresponding to the detailed format, they are displayed in identified mode.
