Before you begin
The list below is numbered for convenience. The steps can be accomplished
in any order.
1 Upgrade to MAT 6.6 or later. Make sure you install all the ITG and
Alarm Management applications.
2 Upgrade Meridian 1 X11 software to Release 25 or later. ITG ISL
Trunks require packages 145 (ISDN) and 147 (ISL). Install additional
software packages, such as Package 148 NTWK, as required for
advanced ISDN features. Table 1, “Software packages for Meridian 1
ITG ISL Trunk,” on page 22 lists required software packages.
3 Download the ITG 8-port upgrade software from the website. The
website URL to check the latest recommended ITG software release
is:

The filename that you want to download is called “ITG28xx.mms”
where “ITG2” indicates the ISL trunk software, “8” indicates it is the
upgrade software for an 8-port card, and “xx” is the software revision
level.
4 If you are adding 24-port cards to the 8-port node as part of the
upgrade, check that the required LAN networking equipment and
cables are installed. For networking equipment requirements, turn to
“ITG Engineering Guidelines” on page 71. Leader 0 and Leader 1 must
be on the same subnet T-LAN.
WARNING
It is critical that you install only the 8-port software on the
8-port cards. If you install the 24-port software, the 8-port
card will become unusable and must be returned to Nortel
Networks for repair.
