Ethernet IP Traffic and Remote M&C Connectors
Four gigabit ethernet RJ45 connectors are provided on the base unit for modem
Monitor and Control (M&C), satellite IP traffic and for connecting to other
QMultiFlex-400™ units for demodulator expansion purposes.
Ethernet speed, duplex and cable termination (crossover versus straight-through)
are auto-negotiated. Line speed and duplex can also be set to fixed values.
Figure 5-5 Base Modem Ethernet RJ45 Ports
M&C control can be via the Simple Network Management Protocol (SNMP), an
embedded web server that sends web pages to a web browser, a Telnet-style
terminal emulation application or via TCP packets that encapsulate Paradise
Universal Protocol (PUP) commands.
SNMP is disabled by default and must be enabled before it can be
used. Once enabled, the modem will always respond to SNMP
commands regardless of whether it has been placed in a mode that
restricts user control to the front panel only.
When using the M&C interface, an M&C IP address (including subnet mask and
default gateway) must be set. An IP traffic address is not required when operating in
Ethernet bridging modes. IP addresses are described in

Terrestrial Interface Positions
With the QMultiFlex-400™ an ethernet processing card is installed as standard. The
other interface slot is not currently used. The connections are shown below. A short
Ethernet cable (shown in orange) is required to connect the IP processing card and
the base Modem. It is important that this connection is between the base Modem IP
traffic port 1 (next to M&C port) and the IP Processing card port IP4. Do not plug
anything into ports IP2 & IP3 on the IP card.
