9.5 Definitions
If there is a software version mismatch between the TE and MS the lowest common version will be
used. The TE is initiating the version check by sending the test command message during the start up
of the multiplexer. The multiplexer version numbers have to be compared on both sides. In the future
software including the multiplexer version check shall be used.
Example:
The MSMUX_VERSION2 ´Request Test Message´ is shown as hexadecimal dump send from the MS.
The version number is indicated in the last 3 bytes (32 00 00).

9.5.1 Coding of "TestCommand" message
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 10.
(see GSM recommendation 07.10 / chapter 5.4.6.3.4)
Table 10: IEI coding
8 7 6 5 4 3 2 1
0 0 0 0 0 1 0 0 TEMUX_VERSION
0 0 0 0 1 0 0 0 MSMUX_VERSION
Other values
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. So it is possible 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). Digit
which are not used are sent as zero string in the test message.
