1.1.2 L-IP Redundant
The L-IP Redundant CEA-709/IP Router is a perfect solution for networks where a high
reliability in the communication is required. It is a member of the L-IP family, based on the
standard L-IP router and adds functionality which allows building redundant network
infrastructure.
An L-IP Redundant CEA-709/IP Router can be used as a single device to achieve the
redundancy on the CEA-709 (TP/FT-10) channel by building a ring structure. Full
Redundancy on the IP-Channel

and on the CEA-709 channel can be achieved with two
devices installed in parallel. In this case device redundancy is ensured as well by mutual
monitoring of paired L-IP Redundant devices.
In addition the L-IP Redundant CEA-709/IP Router monitors the nodes on the TP/FT-10
channel and creates an alarm if a node gets offline. Thereby a cable break on the TP/FT-10
channel can be easily located. The L-IP Redundant only supports the “Configured Router
Mode”.
As an IP-Router the L-IP Redundant CEA-709/IP Router can tunnel CEA-709 packets back
and forth through an arbitrary IP based network, such as a LAN, an Intranet, or even the
Internet. The Router connects to the IP network via an Ethernet channel. The IP
configuration can either be obtained via DHCP or entered manually. The user only needs to
provide the IP address of an CEA-852 configuration server. If operated behind a router with
network address translation (NAT or masquerading), the L-IP Redundant CEA-709/IP
Router supports Auto-NAT to work with dynamic public IP addresses. When using the built
in CEA-852 configuration server, the user can edit and backup the IP channel configuration
through the built-in web server. The configuration is stored persistently and the device
operates completely standalone. After installation, the L-IP Redundant CEA-709/IP Router
is ready to route packets between the CEA-709 network (ring structure) and the IP network.
Thus, all CEA-709 networks connected to L-IP Routers can exchange data over the IP-852
channel. If connected to untrusted networks, such as the Internet, all CEA-852 packets can
