The coding of the multiplexer stack version is used specifically for SIEMENS equipment and 
is not defined in ETSI standards. The IEI values defined for the verification pattern of the 
“TestCommand” message are indicated in Table 7. See GSM recommendation 07.10, 
Section 5.4.6.3.4).

For easier analysis of multiplexer traces the message shall be sent in the following format: 
(1.) Version 

IEI 

(2.)  TEMUXVERSION/MSMUXVERSION (send as ASCII) 

 

(3.)  Version Number (1...999 send as ASCII) 
 
The message part after the Version IEI is coded with ASCII characters. This allows to read 
the version information from the trace file.  
The version number must have a value between 1-999. If not all digits of the version number 
are used only the used digits are coded as ASCII sign(s). Digits that are not used are sent as 
zero string in the test message.
