DTMX5000 IP Gateway Introduction
Rev. 1 1–9
1.4 DTMX5000 Configuration
The DTMX5000 must be connected to a local serial terminal in order to enable definition
of the unit’s essential configuration parameters.
The DTMX5000 also can be accessed and configured remotely using the unit’s NMS. In
addition, the unit supports remote configuration via a Telnet terminal.
1.4.1 DTMX5000 Application
The operation of the DTMX5000 is determined by a software application, which is
loaded automatically on Startup. A new release of this application can be downloaded to
the DTMX5000 from a remote station. A new software release also can be downloaded
using FTP.
1.4.2 Local Configuration
The unit’s default operational behavior is determined by a configuration file (CFG.INI),
which resides on the unit’s internal hard drive. This file is persistent and is loaded by
default into memory when the DTMX5000 is started up.
The CFG.INI file can be accessed and edited directly from a locally connected terminal,
in the form of a terminal or PC.
1.4.3 VGA Display
An optional VGA display can be connected to the DTMX5000, for viewing startup and
operational messages.
1.4.4 Remote Configuration
The DTMX5000 also can be controlled and configured remotely from a Telnet terminal.
Setting the relevant parameters via the local terminal can enable Telnet services.
1.4.5 Firmware
The DTMX5000 contains a Field Programmable Gate Array (FPGA) which performs
most of the mapping of IP datagrams onto the MPEG2 transport stream. The
configuration of this FPGA is downloaded by the DTMX5000 application each time the
DTMX5000 restarts.
