still takes finite time for messages to propagate. However, this is usually
not a factor.
The main reason for attempted call mismatches are:
The outgoing side records every SETUP message sent to it bythe PBX.
The incoming side records SETUP messages sent to the PBX by the
ITG card. Every call that is cleared quickly or blocked by fallback skews
the results.
IP Trunk 3.01 (and later) upgrades
Several differenttypes of upgrades can be required for the IP Trunk 3.01
(and later); for example,a software upgrade for bug fix and/or the addition
of new features. All upgrades are accomplished by updating the on-board
application flash memory with the application. Software upgrades are
performed from the TM 3.1 PC.
Nortel recommends loading the application from the network, rather than
the faceplate PC Card.

Application upgrade

On occasion, a field up-issue is done over the network. In this instance,
the customer is provided with a customer-specific binary file containing a
new software load. The binary file includes both the base code and the
application code.

Maintenance or bug fix upgrade

The user installs the new software from the network.

Patching tool

A patch is a piece of code that is inserted or patched into an executable
program. The patching tool enables loadware on the Media Card 32-port
and ITG-Pentium 24-port trunk cards to be patched or fixed without having
to upgrade the IP trunk card loadware and without service interruption.
All patch commands on the Media Card 32-port and ITG-Pentium 24-port
trunk cards are accessible at the ITG> shell prompt. These commands are
summarized in Table67 "Patch commands" (page 411).
The parameter string supplied to the command must be enclosed with
double quotes. For example, the syntax for the pload command is pload
"patch1.p".
These commands are used to manage patches on the Media Card 32-port
and ITG-Pentium 24-port trunk cards. Patches must be downloaded from a
workstation to the Media Card 32-port and ITG-Pentium 24-port trunk cards
