Introduction DTMX5000 IP Gateway
1–2 Rev. 1
1.2 Description
On the input-side, the DTMX5000 connects to two 10/100 BaseT Local Area Networks
(LANs). To ensure security and support high availability, the DTMX5000 has two
separate 10/100 BaseT Network Interface Cards (NICs).
Transportation NIC Data from this NIC can only be forwarded to the
DVB channel. This NIC can be connected to an
unsecured network (such as the Internet).
Control and Management NIC Connected to a secured network.
The DTMX5000 links to a DVB modulator for the Single Channel per Carrier (SCPC)
transmissions, or to a DVB Multiplexer (Mux), connected to a QPSK modulator in the
case of Multiple Channels per Carrier (MCPC) transmissions. The DTMX5000
environment is shown in Figure 1-2.
