7.6 Ethernet Interface
7.6.1 Overview
The RCP2 Ethernet port (J9) supports several IP network protocols to provide a full
featured remote M&C interface over an Ethernet LAN.
• IPNet protocol — redirection of standard Paradise Datacom LLC serial
protocol over UDP transport layer protocol. This protocol is fully supported in
Paradise Datacom LLC’s Universal M&C software.
• SNMPv1 protocol — protocol intended for integration into large corporate
NMS architectures.
• HTTP Web interface — designed to allow platform independent remote
control function for a single RCP2 unit
In order to utilize either of the protocols listed above, the relevant interface option has
to be turned on. Refer to Section 7.5.2 (Setting IPNet interface), Section 7.5.3
(Configure unit to work with SNMP protocol) and Section 7.5.4 (Web interface).
Of course, standard IP level functions such as ICMP Ping and ARP are supported as
well. There is currently no support for dynamic IP parameters settings (DHCP).
7.6.2 IPNet Interface
7.6.2.1 General Concept
Satcom system integrators are recognizing the benefits of an Ethernet IP interface.
These benefits include:
• Unsurpassed system integration capabilities;
• Widely available and inexpensive set of support equipment (network cable;
network hubs);
• Ability to control equipment over Internet;
• Ease of use
Implementation of the raw Ethernet interface is not practical due to the limitations it
places on M&C capabilities by the range of a particular LAN. It is more practical to use
an Ethernet interface in conjunction with the standard OSI (Open System Interconnect)
model to carry a stack of other protocols. In an OSI layered stack, an Ethernet
interface can be represented as a Data Link layer. All upper layers are resolved
through a set of IP protocols. In order to keep data bandwidth as low as possible
(which is important when M&C functions are provided through a low-bandwidth service
channel) the IP/UDP protocol set is used as the Network/Transport layer protocol on
Teledyne Paradise Datacom SSPAs.
