Remote upgrades of the above listed firmware cards are also accomplished
through the use of SDL-2. SMS is no longer used for this purpose.
You can transfer and install upgrade files by any of the following methods:
CommWorks IP Telephony Manager—IP Telephony Manager is an
SNMP-based management program for the CommWorks platform. IP
Telephony Manager provides tools to transfer files to one or more
components simultaneously over an IP network.
Direct Serial Connection—You can connect a serial cable, with null
modem adapter, between a computer and a serial port on a Total Control
NIC, then transfer a file using any serial communications program that
supports ZMODEM file transfers. Refer to the Total Control 1000 Media
Gateway Guide for more information.
SNMP MIB Browser and TFTP Server—If the other two options are not
available, you can use an SNMP MIB browser and an TFTP Server to upgrade
the firmware over an IP network.
SDL2 Utility—The SDL2 utility runs on Windows NT. You can use it to
upgrade the Media Gateway, SIP Proxy Server, Gatekeeper, and Back-end
Servers as follows:
