Upgrade Voice Gateway Media Card software

To upgrade the software on the Voice Gateway Media Card, follow the steps
in Procedure 65.
If Procedure 64 has just been completed, the correct software should have
been verified and obtained for the Voice Gateway Media Card, and the files
transferred to the OTM PC.
Note: A node can contain a mix of Media Cards 32-port and 8-port line
cards and ITG-P 24-port line cards. Each card type has a different
software version. If a node contains a mix of cards, the software upgrade
must be performed separately for each card type. That is, upgrade the
ITG-P 24-port line card’ software and then the Media Card line card’s
software. Downloading ITG-P software to a Media Card takes that
Media Card out of service. If this happens, it is not possible to restore the
Media Card to service by downloading the correct software after the
incorrect software has been used.
Procedure 65
Upgrading Voice Gateway Media Card software from the OTM 2.2 PC
1Open the OTM Navigator, and click on the Services folder. Double-click
the IP Telephony icon.
The IP Telephony window opens.
2Select the Voice Gateway Media Cards that are to be upgraded from the
main card list view. Upgrade all the cards in the node together, unless a
spare card that has older software is being installed.
3Disable all Voice Gateway Media Cards to be upgraded. Use the LD 32
DISI command from OTM Maintenance Windows, the OTM System
Passthru terminal, or a system management terminal directly connected
to a TTY port on the system.
Note: Nortel recommends that a Voice Gateway Media Card be disabled
before upgrading the software. However, it is possible to perform the
transfer of the software to the card while the card is enabled. A Voice
Gateway Media Card does not have to be disabled to transfer the
software; however, the card must be disabled before it is rebooted.
4In the IP Telephony Gateway - IP Line 4.5 main window, select
View > Refresh and verify that the card status is showing “Disabled.”
