dedicated circuit components and hard board wiring are used. This also
provides greater circuit reliability.
• Functionality is enhanced without hardware redesign or even removal and
replacement. Upgrades are done in the field by loading a new image definition.
FPGA and the Boot ROM
FPGAs are dynamic devices because they do not retain their image definition when power is
removed. The image definition for each device is loaded from an image definition file (*.idf) during
the system boot sequence. The TMS contains a boot ROM that statically stores the names of
the .idf files for the devices contained on its motherboard and the modules that are plugged in.
Whenever a new system is installed, an existing system has components added or replaced, or the
system is upgraded, the boot ROM must be verified and, if necessary, modified. See

The MDM can provide 8 DSPs for a total of 16 fax channels per TMS.
The following fax specifications are supported:
• CCITT T.4 and CCITT T.30 for Group III fax compatibility
• Fax pages: A4 only
• Data rate: 9600 baud with fallback rates of 7200/4800/2400 baud
Terminal Server (Optional)
The optional terminal server provides remote access for servers that have Lights Out Management
(LOM) capability. LOM capability is a service requirement and is accomplished through the use of a
terminal server or a VPN.
The terminal server can be configured to provide Telnet port access, remote access to any of the
application or speech processors connected to the server.
