Version matching is achieved through the use of difference (diff) files, each
containing the difference between the CT software version files. The diff files
needed to match CT to the version of 9500 MXC embedded software, are held
within the embedded software set. This means that:
• For a new 9500 MXC installation the version of CT supplied in the Setup CD
will always match the embedded software of the equipment being installed.
• In other situations, the auto version feature delivers transparent version
matching to ensure the version of CT used is always compatible with 9500
MXC software.
The process used by CT to determine the version needed to communicate with
9500 MXC is as follows:
• When a CT start-up is executed (refer to Starting 9500 MXC CT on page 2-19)
the highest version of CT installed on your PC is used.
• Initial communication with 9500 MXC identifies the version of CT needed.
• Where an earlier version of CT is required, CT selects the correct version and
restarts itself.
• Where a later version of CT is needed (not on your PC), CT downloads the
updating difference files from 9500 MXC. During this process the CT Start Up
screen will indicate a later version of 9500 MXC CT is being downloaded. On
completion of the download, 9500 MXC CT will automatically complete the
start up process. The next time you connect to this 9500 MXC there will be no
download, as the updating files are now held on your PC.
• The download time required to update to a later version depends on the number/
size of the diff files needed, and whether your PC connection to 9500 MXC is
by V.24 or Ethernet. Ethernet is much faster. When downloading is initiated, an
on screen message provides an estimation of the time needed.
• An alternative to CT updating using 9500 MXC CT Auto Version, is to update
from the 9500 MXC Setup CD supplied with the Node/Terminal. Refer to
Procedure for Installing 9500 MXC CT on page 2-2. Compared to a V.24
connection, this may provide a quicker update.
When new 9500 MXC software is loaded into a Node/Terminal, you must re-start
CT to trigger auto version matching.
