Outdoor Unit (ODU)
Outdoor Unit and antenna. The ODU is a ruggedized box, often
antenna-mast mounted, that houses a radio modem and connects to
an antenna. It also has an ethernet cable that passes both data and
power to/from the Power Injector. The radio modem and circuit board
inside have flash memory and a standalone CPU that can intelligently
communicate with other systems. Remote management software
configures and controls the ODU.
Outside Link
A link to an outside network node.
Packet
A base unit of data. In networking, a packet defines the syntax of data
transmitted to and from an application.
Packet Scheduler
A packet scheduler determines when packets are sent to an
intermediate router or final destination, as determined by your route
and QoS selection.
Parity Check
Self-checking code that uses binary digits to indicate whether the total
number of ones (or zeros) in each coded expression are always even
or odd. Checks may be made for even, odd, or no parity (checks not
performed).
Peer Group
Logical nodes grouped to create a routing hierarchy.
Peer-To-Peer
Nodes can directly begin communication with each other in a peer-to-
peer architecture
without an intermediary.
Physical Link
A tangible physical link that provides a connection between two
switching systems.
Physical Medium
Physical Medium are actual physical interfaces such as DS1, E1, DS2,
E3, DS3, E4, FDDI-based, Fiber Channel-based, STS-1, STS-3c,
STS-12c, STM-1, STM-4, and STP. These mediums range from
1.544Mbps through 622.08 Mbps in data rate.
Ping
Packet internet groper. A utility program that tests whether
destinations can be reached by sending them an ICMP echo request
and then waiting for a reply. Ping is a useful utility to check whether
equipment is performing and connected properly on the network. Ping
clients are available for the PC, Macintosh, and Unix computers.
PoE Cable
Power-Over-Ethernet Cable. This is a category 5 Ethernet cable that
also includes power in addition to data signals. The cable is a single
interconnect between the ODU and the Power Injector which supplies
the Ethernet connection from the LAN and the power via an AC
adapter that attaches to the Power Injector. Malibu Networks supplies
PoE cables in various lengths.
